This document discusses the organelles and their functions in cells. It identifies the key organelles as the cell membrane, nucleus, nuclear envelope, mitochondria, vacuoles, cytoplasm, chromosomes, chloroplasts, cell wall, and plastids. It then provides more details on the locations and functions of each organelle, such as that the nucleus controls the cell and contains chromosomes and nucleoli, mitochondria produce energy, and chloroplasts trap sunlight and produce food in plant cells.

4. Cell Parts and Functions
Cell Membrane
Protects the cell
Lets things in and out of the
cell
Location: around the
cell
• Nucleus
Control center of cell
Double membrane
Contains
- Chromosomes
-Nucleolus

5. Cell Parts and Functions
Nucleolus (Nucleoli)
Makes ribosome
Location: inside the nucleus
(dark spot)
Nuclear envelope
Protects nucleus
Lets things in/out of nucleus (pores)
Location: around nucleus

6. Cell Parts and Functions
Mitochondria
Makes energy/powerhouse
Location: in cytoplasm

7. Mitochondria

8. Cell Parts and Functions
Vacuole
Stores food and water
Location: in cytoplasm

9. Vacuole

10. Cell Parts and Functions
Cytop lasm
Gel-like substances, holds all
Organelles in cell
Location: in cell
Chromosomes
Contains genetic information/traits
Location: in nucleus

11. Cell Parts and Functions
Ch loroplast
Traps suns energy
and
Makes food
Location: in plant cells

12. Cell Wall
Cell Wall
Protects and supports plant
Cells
Prevents water loss
Cellulose
Location: outer layer of plant
cells

13. Cell Parts and Functions
Plastids
Stores extra food in
Plant cells
Location: in plant cell
