Organelles of Plant and Animal Cells

2. Review of Cell Theory 1. All living things are made of cells.
2. Cells are made from other cells.
3. Cells carry out the basic structure and function of all living things.

3. Two Types of Cells Prokaryotes Eukaryotes First cells to evolve
No nucleus
Heredity information is contained in the cytoplasm
Ex: Bacteria
Eukaryotes
Evolved from prokaryotes
Have a nucleus
Heredity information contained within the nucleus
Ex: Plants, Animals and Fungi

4. The Cell Organelles
Tiny, membrane-bound structures that perform special functions inside the cell.

5. Cell Wall Only found surrounding plant, fungal and bacteria cells.
Provides support and protection for the cell.

6. Cell Membrane Surrounds all cells!
In a plant cell, it lies beneath the cell wall.
Provides the cell with protection and controls the movement of materials in and out of the cell.
City wall

7. Nucleus Found in both plant and animal cells. Large, oval shape.
Nuclear membrane
Found in both plant and animal cells.
Large, oval shape.
Centrally located in the cell.
Controls cell activities.
Contains genetic information (DNA).
It’s like the city hall!

8. Cytoplasm Found in both plant and animal cells.
Clear, thick, jelly-like material.
Located beneath the cell membrane.
Supports and protects the organelles.
It’s like the city’s sidewalks!

9. Golgi Apparatus Found in both plant and animal cells.
Looks like a flattened stack of membranes
Processes and packages molecules, like proteins, that were made by the cell.
It’s like the post office of the cell!

10. Ribosomes Found in both plant and animal cells.
Can be attached to the Endoplasmic membrane or floating free in the cytoplasm.
Produces proteins.

11. Endoplasmic Reticulum
Found in both plant and animal cells.
Network of tubes…like a city’s highway!
Transports material throughout the cell.
Two types:
Rough (covered with ribosomes)
Smooth (no ribosomes)
Rough
City’s highway system.
Smooth

12. Mitochondria Found in both plant and animal cells.
Looks like a jellybean.
Breaks down sugar molecules to release energy.
City’s power plant.

13. Vacuoles Found in both plant and animal cells.
In plant cells: very few and very large.
In animal cells: many little ones.
Fluid-filled sacs.
Store food, water and waste.
City’s power plant.

14. Lysosomes Found only in animal cells. Small and round in shape.
Breaks down larger food molecules into smaller ones.
Digests old cell parts.
Recycling center

15. Chloroplasts Found only in plant cells. Oval shaped.
Green in color due to chlorophyll.
Uses energy from sun to make food for the plant.
Solar panels
