Small rings of DNA

3

What is a light microscope?

It lets us see large subcellular particles

4

What does the cell wall do?



Strengthens the cell

5

What does the mitochondria do?

Gives the cell energy

6

What does the nucleus do?

Contains all the DNA

7

What does the cell membrane do?

Controls what enters or leaves the cell

8

What do ribosomes do?

Make proteins

9

What does the vacuole do?

Contains cell sap

10

What do the chloroplasts do?

Absorbs light so photosynthesis can happen

11

What is an electron microscope?

Let’s you see smaller subcellular particles

12

What is a prokaryotic cell?

They are smaller and simpler cells like bacteria

How do you prepare a slide for a microscope?

Add water to a slide
Cut up an onion and peel off an epidermis layer
