Cells and Their Organization

Level of Organization

Organelle - CO2, H20, N20

Cell - Plant cells, animal cells

Tissue - Lung tissue, esophageal tissue

Organ - Heart, liver

Organ system - Digestive, endocrine

Animal Cells:

Nucleus = The largest organelle in the cell

Cell Membrane = Many substances pass through, permeable to carbon dioxide

Mitochondria (Singular for Mitochondrion) = There are more of them that need a lot of energy, such as muscle or nerve cells

Cytoplasm = A living material that makes up a cell

Plant Cells:

Nucleus = The largest organelle in the cell

Cell Membrane = Many substances pass through, permeable to carbon dioxide

Mitochondria (Singular for Mitochondrion) = There are more of them that need a lot of energy, such as muscle or nerve cells

Cytoplasm = A living material that makes up a cell

Chloroplasts = Absorb light energy to make food in the process of photosynthesis

Vacuole = A large central space surrounded by a membrane

Cell Wall = A layer of non-living material that is found outside the cell membrane of plant cells.
