Write down at least three things you see that are the same.

Then write down at least three things you see that are different.

Today’s Lesson

• Students will differentiate between structure and function in plant and animal cell organelles, including

cell membrane, cell wall, nucleus, cytoplasm, mitochondrion, chloroplast, and vacuole.

What is Structure?

• Structure is what an object looks like or how it is made.

• Can you describe the structure of the object below?

What is function?

• Function is what something does, or its JOB.• What is the function of the objects below?

What if it’s structure was different? How would that affect it’s function?

Or

Main Point

• An object’s structure determines its’ function. How it’s made determines what it does.

*Cell Membrane

• Cell Membrane-Controls what goes in and out of the cell

• How does the cell membrane’s structure determine it’s function?

*Cell Wall

• Cell Wall-A cell wall gives a plant cell structure and support.

• How does a cell wall’s structure determine it’s function?

*Nucleus

• Nucleus-the brain of the cell. Controls all the cell activities and holds the DNA.

• How does a nucleus’ structure determine it’s function?

*Cytoplasm

• Cytoplasm- The jelly-like liquid in a cell that holds all the cell parts(organelles) and helps organelles move.

*Mitochondria

•Mitochondria-Releases energy for the cell to use.

*Chloroplast• Chloroplast-contains chlorophyll, traps

energy from the sun, performs photosynthesis and gives energy in the form of glucose(plant sugar)to the plant cell.

*Vacuole

• Vacuole-stores water and waste in both plant and animal cells

• How does a vacuole’s structure determine it’s function?
