You explored the cell during the webquest

2

Now we will discuss a few of the more common cell organelles

3

Vocabulary:

organelles

Parts of a cell that do different jobs in the cell

4

1. Can find in both plant and animal cells

2. Gives support and protection to the cell

3. Controls entry in and out of the cell

Cell Membrane

5

Vocabulary:

Cell membrane

A part of the cell that controls entry in and out of the cell

Nucleus

6

1. Large and oval in appearance

2. Controls cell activity

3. The brain (or boss)

7

Vocabulary:

nucleus

A part of the cell that controls the activity of a cell (brain)

Cytoplasm

8

1. Clear, thick jelly like substance that holds the organelles

2. Supports and protects the organelles

9

Vocabulary:

cytoplasm

A part of the cell that supports and protects organelles

Endoplasmic Reticulum

10

1. Network of tubes or membrane

2. Carries materials through the cell

3. The “conveyor belt” of the cell

11

Vocabulary:

Endoplasmic reticulum

Part of the cell that carries materials throughout the cell

Ribosome

12

1. Small round bodies attached to the endoplasmic reticulum or floating in the cytoplasm

2. Produces proteins

3. Looks like little ticks

13

Vocabulary:

ribosomes

Part of the cell that produces proteins for the cell

Mitochondrion

14

1. Bean shaped with inner membranes

2. Breaks down sugar molecules into energy

15

Vocabulary:

mitochondria

Part of the cell that breaks down sugar molecules to make energy

Vacuole

16

1. Fluid filled sacs

2. Stores food, water, and wastes

3. The “storage containers” of the cell

17

Vocabulary:

vacuole

Part of the cell that stores food, water and wastes in a cell
