7.12D Differentiate between structure and function in plant and animal cell

organelles, including cell membrane, cell wall, nucleus, cytoplasm, mitochondrion, chloroplast,

and vacuole

• Structure: Flexible Membrane with small holes, Surrounds cells (outside layer for animal cells, just inside cell wall for plants)

• Function: Controls what goes in and out of cell (transports material) & Holds in cytoplasm

• Analogy: It is like the bright orange flexible fencing around construction sites because it protects the work site while still allowing things to go through.

Structure: Gel-like fluid made mostly of water

The material inside the membrane

Function: •Holds organelles •keeps cell flexible•maintains shape of cell

Analogy: It is like the water in a swimming pool because all the stuff that happens in the pool happens in the water. The water supports the swimmer like cytoplasm supports organelles

Plant Cell

Animal Cell

Plant Cell

Animal Cell

Structure: Bean shape with many layers inside

Function: Transforms energy (from nutrients and Oxygen) for cells to use

Analogy: Mitochondria act like a power plant because they both transform other materials to make energy. Plant Cell

Animal Cell

Plant Cell

Animal Cell

Structure: Large and round, will usually be located towards the middle of the cell. Membrane bound (eukaryotic)

Function: Contains genetic material (DNA), controls cellular activities

Analogy: The nucleus is like the brain of a human because the brain controls the actions of the body like the nucleus controls the cell.

Plant Cell

Animal Cell

Structure: Flat, folded membrane, usually around the nucleus

Function: Makes proteins for the cell. Internal delivery system.

Analogy: ER is like a factory that produces goods and ships what they have made.

Structure: Stacked membranes

Function: Packages and delivers materials made from ER. In plants, the Golgi made cell wall material.

Analogy: Golgi bodies are like FedEx because they package and ship materials around and out of cell.

Structure: small and round, usually more found in animal cells. Can move within cells.

Function: Digestion of cellular waste. Recycles old cell material to make new molecules.

Analogy: Lysosomes are like your digestive system because both can break apart larger materials to make new molecules.

Structure: small and round in animal cells, usually a single large bag-like structure in plants

Function: stores water and nutrients, aids(helps) in cellular digestion. In plants it works with the cell wall for cell support (turgor pressure).

Analogy: A canteen is like a vacuole because both are used to store water.

Structure: green, bean shaped – found only in plant cells

Function: contains chlorophyll that makes photosynthesis possible

Analogy: Kitchens are like chloroplast because both make “food” for organisms.

Only in plant cells!

Structure: rigid material that forms the outer layer of plant cells.

Function: gives plant cells support and protects cell’s interior.

Analogy: Walls of a building are like a cell wall because both are used for support.
