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 dioxideMitochondria (Singular for Mitochondrion) = There are more of them that need a lot of energy, such as muscle or nerve cellsCytoplasm = 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 dioxideMitochondria (Singular for Mitochondrion) = There are more of them that need a lot of energy, such as muscle or nerve cellsCytoplasm = A living material that makes up a cellChloroplasts = Absorb light energy to make food in the process of photosynthesisVacuole = A large central space surrounded by a membraneCell Wall = A layer of non-living material that is found outside the cell membrane of plant cells.
