CYCLES: CHAPTER 2 CELLS

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

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

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

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

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

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

CELL DIVISION How did I get so big?

Amazing! Cell Division That’s how you grew!

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

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!
