1. CYCLES: CHAPTER 2
CELLS

2. CELLS LESSON OUTLINE The building blocks of life The plant cell
The animal cell
Cell growth

3. The Building blocks of life
A cell is a single unit of life
All living things are made up of at least one cell
Can you guess what the world’s smallest living thing is?
Plant cells under a microscope

4. Types of cells Two basic types of cells PLANT ANIMAL
Different types of cells share common features
Different cell parts carry out different functions
Two basic types of cells
PLANT
ANIMAL

5. Controls activities of cells, holds genetic information
PLANT CELL
Functions
Supports and shapes cell
Contains chlorophyll
Where new substances are formed
Controls activities of cells, holds genetic information
Controls movement of materials in and out of cell
Cell parts of a typical plant cell

6. Function: Partially permeable layer that controls materials moving in and out
ANIMAL CELL
Function: Jelly-like substance; holds cell parts; where new substances are made
Cells parts of a typical animal cell
Function: Controls activities of cell; holds genetic information

7. Vs PLANT CELL ANIMAL CELL FEATURE CELL WALL CELL MEMBRANE CYTOPLASM
NUCLEUS CHLOROPLAST
YES NO
YES

8. CELL DIVISION
How did I get so big?

9. Amazing!
Cell
Division
That’s how you grew!

10. How does it work? 2.The two new cells are called “daughter” cells
Cell division splits a cell to form two new ones

11. I learned that: A cell is a single unit of life
All living things are made up of at least one cell
Different types of cells share common functions
Cells division is how living things grow!
