All living things are made of one or more cells. Cells are the basic building blocks of all organisms. The organization of cells into complex structures allows for the wide variety of life found in multicellular organisms.

Assignment...Choose one of the topics below to complete your post for this week. (use study islande
  1. Compare and contrast plant vs. animal cells
  2. Compare and contrast single cellular vs. multicellular organisms
  3. Describe, starting with organelles, how small building blocks come together to form whole organisms.

  • detailed answer and complete thoughts (5 points)
  • 5 or more sentences (5 points)



Standard OH Grade 6-8, Science Standard Life Sciences A
Explain that the basic functions of organisms are carried out in cells and groups of specialized cells form tissues and organs; the combination of these cells make up multicellular organisms that have a variety of body plans and internal structures.

Animal Cell Plant Cell
Nucleus: Present Present

Cilia: PresentIt is very rare

Shape: (animal cell)Round (irregular shape) (plant cell)Rectangular (fixed shape) Chloroplast: Animal cells don't have chloroplasts Plant cells have chloroplasts because they make their own food.Cytoplasm: Present Present Endoplasmic Reticulum (Smooth and Rough): Present Present. Ribosomes: Present Present.Mitochondria: Present Present.Vacuole: One or more small vacuoles (much smaller than plant cells).One, large central vacuole taking up 90% of cell volume.Centrioles: Present in all animal cells Only present in lower plant forms.Plastids: Absent Present.Golgi Apparatus: Present Present.Cell wall: Absent Present.Plasma Membrane: only cell membrane cell wall and a cell membrane.Microtubules/ Microfilaments: Present Present.Flagella: May be found in some cells May be found in some cells.Lysosomes: Lysosomes occur in cytoplasm. Lysosomes usually not evident.

While plant and animal cells share many organelles, there are a few organelles that are specific to plant cells. These organelles include the cell wall and chloroplasts. The cell wall provides protection from physical injury and, with the vacuole, it provides structural support. It is made mostly of a structural material called cellulose, which makes plant cells more rigid than animal cells. The chloroplasts are the food producers in a plant cell. These small green organelles use energy from the Sun to perform photosynthesis.

My report well be on plant vs animal cells. plants and animals cells share many things but do have there differences. both plant and animals have a mitochondria,nucleus,cell membrane, and mitochondria. a animal cell has vacuole but a plant cell dose not. a plant cell has an chloroplasts, cell wall,and a central vacuole but a animal cell has none of these.

Plant vs . Animal cells .
Plant and animal cells have some of the same organelles , but also different . The Cytoplasm , the cell Membrane , and Vacuole are found in both plants and animals . Plants have Cell walls and Chloroplast , and does not share this with animals . The cell wall provides protections from physical injury . These are a few things about these two different types or living organisms .

Plant cells have chloroplasts ,And animal do not have that they have cytoplasm . Plants have cell walls animal cell do not. And both Plants An animals both have cytoplasm. Plant cells are square and animal cells are circle. Plant cells give support , but animal cells give no support.

My topic is Compare and contrast plant vs. animal cells.
While plant and animal cells share many organelles, there are a few organelles that are specific to plant cells. These organelles include cell wall and chloroplasts. Both the plants cell and the animal cell have vacuole. The vacuole stores water and ingested food in a fluid sack and helps remove waste from the cell. both plants cells and animals cells are living Organelles.

Compare an contrast plants vs animals

One thing that plants and animals have in common is they both have cells. And other things they are in common with is The cytoplasm is the suspension fluid that contains all of the organelles of the cell located between the nucleus and the cell membrane, as well as the support structures that help give the cell its shape.

The third thing in common is the
The cell membrane (or plasma membrane) acts as a boundary layer around the cytoplasm that separates a cell from the outside environment. In addition to being able to recognize chemical signals, the cell membrane is selectively permeable to chemicals, and it controls which substances enter and leave the cell.

The forth thing in common is A vacuole stores water and ingested food in a fluid sack and helps remove waste from the cell. While both plant and animal cells can have vacuoles, the vacuoles found in animal cells are very small, while plant cells have one large, central vacuole. The central vacuole in plants produces turgor pressure against the cell wall for cellular support.
The nucleus is the control center of the cell.
The ribosomes are organelles that participate in the production of proteins.

The mitochondria take in nutrients, break them down, and create energy for the cell.

Things that are different from plant an animals cell are:

The cell wall provides protection from physical injury and, with the vacuole, it provides structural support. It is made mostly of a structural material called cellulose, which makes plant cells more rigid than animal cells.

The second thing that is different is The chloroplasts are the food producers in a plant cell. These small green organelles gets energy from the Sun to perform photosynthesis.


Compare and contrast single cellular vs. multicellular organisms.

Single-celled, or unicellular, organisms may live alone or may live of others. Many single-celled organisms can move around the environment their around. Single-celled organisms can reproduce themselves, but some reproduce sexually.


Multi-celled, or multicellular, organisms can have many different kinds of cells.Cells from multi-celled organisms cannot survive on their own. The cells have work together to be able to get food and air and to help the organism reproduce. Multi-celled organisms are made up millions and trillions of cells.All animals and plant are Multi-celled organisms

cells are a part of are body and they help us breathe and fight off sickness. they can help us live. and help are bad cells.

Animals cells are different from the plant cells because of different reproduction and different jobs that they do. They are the same by the same name and the same purpose. These cells also can be entertaining by learning about.

Compare and contrast plants and animal cells.

Similarities: Both plant and animal cells have nuclei. They both contain cytoplasm. And both have a cell membrane.

Differences: Plant cells have a cell wall, animal cells, do not. Plant cells have chloroplast, and animal cells do not. Plant cells have large vacuoles, and animal cells never do.

A plant cell has a vacuole. This is a sac in which the cell stores water and nutrients. An animal cell has no vacuole as it does not make its own food and therefore does not need to store these nutrients in that way.

The animal cell has a cell membrane and the plant cell has a cell wall. Both perform the same main function - they are a semipermeable membrane that controls the entry and exit of gases and substances to and from the cell.

1.A plant has a cell wall and a chloroplast.A animal cell has vacuoles. They both have a nucleus and a cell membrane.
2.A single cell can take care of its self a multi-celled cannot take care of it self.They both need cells to survive.
