THE CELL

What is the smallest LIVING unit of LIVING THINGS?

• a cell

• a mitochondria

• a brick

• a protein

Plant and animal cells...

• are different, because plant cells have two extra parts

• are exactly the same

• are the same, except that plant cells don't have a cell membrane

The cell membrane...

• is like a wall that blocks everything from going into the cell

• controls what can go into or out of a cell

• is hard and rigid, and gives the cell its shape, like an exoskeleton

Which part of the cell CONTROLS everything that happens in the cell?

• mitochondria

• nucleus

• cell membrane

• vacuole

Which part of the cell STORES water and minerals?

• mitochondria

• nucleus

• cell membrane

• vacuole

Where do cells come from?

• They come from eggs.

• They come from minerals in water.

• They come from other cells.

How do cells reproduce?

• They lay eggs.

• One cell divides to make 2 cells (etc.)

• Two cells combine and then make 4 cells.

Which part of the cell is a watery, jelly-like substance?

• cytoplasm

• nucleus

• vacuole

• cell wall

Which parts do ONLY plant cells have? (Animal cells don't have them!)

• vacuoles and mitochondria

• nucleus and chloroplasts

• chloroplasts and cell membrane

• cell wall and chloroplasts

In PLANT cells, which part is the rigid outer layer that supports and protects the cell?

• cell membrane

• cell wall

• chloroplast

• nucleus
