Life is very diverse and living things come in all shapes and sizes.  For this week research different types of living things and write about them. 

Step by step directions:
  1. Look up two types of plants; one example of a vascular plant and one example of a non-vascular plant.  Please write their scientific name (genus and species) and provide a brief description of them.
  2. Look up two types of animals; one example of a vertebrate and one example of an invertebrate.  Please write their scientific name (genus and species) and provide a brief description of them.
  3. Look up one example of a single cellular organism and one example of a multi-cellular organism (you can use one of your examples from above if you want.  Write a brief description and their scientific name.

1.The first plant I found is called Lycopodiophyta but people call it Lycopods this plant lived up to 410 million years old and this is a Vascular and the other plant is call Moss it is callified as Bryophyta .

Moss is a nonvascular plant because They have no vascular tissues that help transport water and nutrients. A fern is a vascular plant beacuse A vascular plant has three main kinds of organs: roots, stems and leaves.Verterbrate animals have a back bone like a dog or a cat.Nonverterbrate animals have no spine like a worm or a snail.Single-cell organisms, such as bacteria and protozoa.Some multiorganisms are humans AKA homosapien
because we have vains that pump blood through are entire body.

A fern is a vascular plant,A vascular plant has three main kinds of organs: roots, stems and leaves. The roots are the part of the plant that grows underground. Roots give a plant support, anchoring it into the soil. They also collect water and minerals from the soil. Some plants store excess food in the roots for the plant to use later. Carrots and turnips are examples of plants that store food in their roots...Nonvascular plants are the simplest types of plants and most similar to their algal ancestors. They have no vascular tissues that help transport water and nutrients. Instead, they rely on diffusion from cell to cell, which can be a very slow and inefficient process. This is why nonvascular plants tend to be very moss

Vascular plants (also known as tracheophytes or higher plants) are those plants that have lignified tissues for conducting water, minerals, and photosynthetic products through the plant. Vascular plants include the clubmosses, Equisetum, ferns, gymnosperms (including conifers) and angiosperms (flowering plants). Scientific names for the group include Tracheophyta[2] and Tracheobionta,[3] 1. Vascular plants have vascular tissues which circulate resources through the plant. This feature allows vascular plants to evolve to a larger size than non-vascular plants, which lack these specialized conducting tissues and are therefore restricted to relatively small sizes.
2. In vascular plants, the principal generation phase is the sporophyte, which is usually diploid with two sets of chromosomes per cell. Only the germ cells and gametophytes are haploid. By contrast, the principal generation phase in non-vascular plants is usually the gametophyte, which is haploid with one set of chromosomes per cell. In these plants, generally only the spore stalk and capsule are diploid.

One possible mechanism for the presumed switch from emphasis on the haploid generation to emphasis on the diploid generation is the greater efficiency in spore dispersal with more complex diploid structures. In other words, elaboration of the spore stalk enabled the production of more spore and the ability to release it higher and to broadcast it farther. Such developments may include more photosynthetic area for the spore-bearing structure, the ability to grow independent roots, woody structure for support, and more branching.

Water transport happens in either xylem or phloem: xylem carries water and inorganic solutes upward toward the leaves from the roots, while phloem carries organic solutes throughout the plant.Non-vascular plants is a general term for those plants without a vascular system (xylem and phloem). Although non-vascular plants lack these particular tissues, a number of non-vascular plants possess tissues specialized for internal transport of water.

Non-vascular plants do not have a wide variety of specialized tissue. Liverworts have structures that look like leaves, but they are not true leaves because they have no xylem or phloem. Likewise, mosses and algae have no such tissues.

All plants have a life cycle with an alternation of generations between a diploid sporophyte and a haploid gametophyte, but only nonvascular plants can potentially have a dominant gametophyte generation. In these plants, the sporophytes grow from and are dependent on gametophytes for taking in water and other materials.
The term non-vascular plant is no longer used in scientific nomenclature. Non-vascular plants include two distantly related groups:

* Bryophytes - Bryophyta (mosses), Marchantiophyta (liverworts), and Anthocerotophyta (hornworts). In these groups, the primary plants are the haploid gametophytes, with the only diploid portion being the attached sporophyte, consisting of a stalk and sporangium. Because these plants lack water-conducting tissues, they can't become as tall as most vascular plants.
* Algae - especially the green algae. Recent studies have demonstrated that the algae actually consist of several unrelated groups. It turns out that common features of living in water and photosynthesis were misleading as indicators of close relationship. Only the Archaeplastida are still considered relatives of the plants.

Both of these groups are occasionally termed the "lower plants"; the term "lower" refers to these plants' status as the earliest plants to evolve. However, the term "lower" plants is not precise, since it frequently is used to include some vascular plants, the ferns and fern allies.

In the past, the term non-vascular plant included not only all the algae, but also the fungi as well. Today, it is recognized that these groups are not closely rela

The word vertebrate derives from the Latin word vertebratus (Pliny), meaning joint of the spine.[5] It is closely related to the word vertebra, which refers to any of the bones or segments of the spinal column.[6]

n invertebrate is an animal (a multi-cellular eukaryote) without a backbone. The group includes 97% of all animal species[1] – all animals except those in the chordate subphylum Vertebrata (fish, amphibians, reptiles, birds, and mammals).

Invertebrates form a paraphyletic group. Given a common multicellular, eukaryotic ancestor, all contained phyla are invertebrates along with two of the three subphyla in Phylum Chordata: Urochordata and Cephalochordata. These two, plus all the other known invertebrates, have only one cluster of Hox genes, while the vertebrates have duplicated their original cluster more than once.

Within palaeozoology and palaeobiology, invertebrates are often studied within the fossil discipline called invertebrate palaeontology.
The word invertebrate comes from the word vertebrate, with the prefix in- attached to it.[2] Thus, the w

1. The one vascular plant I found was a fern(pteridophyta.ferns are plants that do not seed or make flowers. The non-vascular plant I found was mosses(pediastrum boryanum). I found out that mosses like to grow in damp and shady places.Just like the fern, moss does not flower or make any seeds. They also grow in clumps.
2. Invertebrates are animals that do not have backbones. The one invertebrate that I chose to do was a sponge(porifera). Sponges have a jelly-like layer in-between more layers of cells.They have cells that are specialized to do specific things but they also have cell that can transform into other types of specialized cells. The one vertebrate that I researched was a salamander. I found that most amphibians are characterized as salamanders but the real salamanders are characterized as having slender bodies,short noses and long tails. Salamanders can also make new limbs if one happens to have been disconnected.
3. Mosses are multi-celled organisms that don't reproduce. Bacteria(prokaryote)are single celled organisms. They come in many shapes and sizes.

I am doing this subject is about plants and they are Ferns and Liverworts.Some of the liverworts are floating aquatics, but most of them grow on logs or rocks or upon damp ground. They are found at their best in damp, shady places. Many of them may be kept indefinitely in the greenhouse. Riccia, Marchantia, Conocephalus, Asterella,and many others vegetate luxuriously, and often fruit if kept on moist soil in a shady part of the greenhouse, and they do fairly well in the ordinary laboratory if covered with glass and protected from too intense light

Liverwort (hepatica) is an example of a non-vascular plant.Liverwort can vary in size from 5mm to 50mm. An example of a vascular plant is ferns (disambiguation). A fern is any one of a group of 12,000 species of plants belonginng to botanical group pteridophyta. The loins mane jellyfish (cyanea) is an example of a invertebra and is the largest jellyfish in the world. It is named so because of its large tenticals. A giraffe (disambigution) is an example of a vertebra. The giraffe is a good example of a vertebra becuase of its long neck and back. The atom (disambiuation) is an example of a sigle selled organism. The atom is a basic unit of mater that consists of a thin nucleus.

1.Moss is a nonvascular plant.Nonvascular plants have no stem and leaves. Trees are a vascular plant.A vascular plant has three main kinds of organs: roots, stems and leaves.

2.Octopuses are invertebrates.Invertebrates are animals that do not have a backbone, or any other types of bones.Wolves are vertebrates.Vertebrates are animals that have backbones.

3.Bacteria is a single-cell.Single-celled organisms perform all of their life processes within a single cell.Tiny mite is a multi-cell
Multi-celled, or multicellular, organisms may have many different kinds of cells.
