Cell Structure

1
Cell Structure Function

• Looking Inside Cells
• Chapter 1
• Section 2

2
Organelles

• Tiny cell structures that make up a cell

3
Cell Wall

• Rigid layer of nonliving material that surrounds
  the cells of plants
• Protects the cell
• Supports the cell

4
Cell Membrane

• Controls what substances come into and out of the
  cell

5
Nucleus

• The cells control center, directing all of the
  cells activities

6
Cytoplasm

• Gel-like fluid that supports the organelles
  inside the cell

7
Mitochondria

• Produce most of the energy for the cell
• Powerhouse

8
Endoplasmic Reticulum (ER)

• Transports protein throughout the cell

9
Ribosomes

• Produce the cells proteins
• Located on the Rough ER

10
Golgi Bodies

• Modify proteins
• Continue to transport proteins

11
Chloroplasts

• In Plants
• Organelle that capture energy from sunlight and
  use it to produce food for the cell

12
Vacuoles

• Storage areas for the cell
• Water
• Waste
• Nutrients

13
Lysosomes

• Use strong chemicals to digest things like
• Food particles
• Old/Dead organelle
• Foreign invaders

14
Bacteria

• Single celled organisms
• Has
• Cell wall
• Cell Membrane
• Does not have
• A real nucleus

15
Specialized Cells

• Each type of cell is specialized
• Skin
• Bones
• Muscles
• Blood
• Brain
• Liver
• Stomach
