4.Cell Organelles 1

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 3.The “power plant” of the cell

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

Lysosome 18 1.Small and round with a membrane 2.Breaks down food molecules 3.Digests old cell parts

19 Vocabulary: lysosome Part of the cell that breaks down food molecules and digests old cell parts

Chloroplast 20 1.In plant cells only 2.Green and oval with chloroplasts 3.Uses energy from the sun to make food

21 Vocabulary: chloroplast Part of the plant cell that uses energy from sun to make food

Cell Wall 22 1.In plant cells only 2.Rigid outer layer that gives support and protection to the cell 3.Allows H 2 O, CO 2, and O 2 to pass in and out of the cell

23 Vocabulary: Cell wall Part of the plant cell that provides support and protection
