The Cell TheoryThe Cell Theory

1. All organisms are made of cells.
2. The cell is the basic unit of life in all living things.
3. All cells come from existing cells.

Two Types of CellsTwo Types of Cells

Prokaryotic Cells: Prokaryotic Cells:

• (^) Have no membrane covered nucleus
• (^) Have no membrane
  • covered organelles
• (^) Have circular DNA
• (^) Are bacteria

Two Types of CellsTwo Types of Cells Eukaryotic Cells: Eukaryotic Cells:

• (^) Have a nucleus
• (^) Have a membrane - covered organelles
• (^) Have linear DNA
• (^) Are all other cells

Cell MembraneCell Membrane

• (^) Outer layer of cell
• (^) Allows nutrients into the cell and wastes outside of the cell Cell Membrane “Gate into the city”

CytoplasmCytoplasm

Cytoplasm a jelly-

like fluid contained

in the cell that

holds the organelles.

The Nuclear MembraneThe Nuclear Membrane

The nucleus is surrounded by double membrane.

- It controls the passage of substances between the nucleus and the cytoplasm. DNA Nuclear Membrane Nucleolus

MitochondriaMitochondria

Power center of cell

- Provides the energy the cell needs to move, divide, etc. Outer Membrane Inner Membrane

Endoplasmic ReticulumEndoplasmic Reticulum

- Transportation system of cell - Rough ER- ribosome's attached - Smooth ER- no ribosome's Ribosomes Endoplasmic Reticulum “Roadways of the cell”

Endoplasmic ReticulumEndoplasmic Reticulum

- Two types: - (^) Smooth- is generally used for the creation/ storage of lipids and steroids. - Rough - plays a significant role in the synthesis of various proteins Ribosomes Endoplasmic Reticulum

LysosomesLysosomes

- Digests food particles and cell parts - Protects cell by digesting foreign invaders

Animal Cells

• (^) Nerve cells
• (^) Blood cells
• (^) Muscle cells
• (^) Skin cells
• (^) Fat cells Types of Animal Cells

Animal Cells

• (^) Blood cells carry oxygen to the body’s tissues and collect carbon dioxide. They also carry hormones, enzymes, and vitamins to different parts of the body. Each type of animal cell is specialized to do different jobs. red blood cell white blood cell

Animal Cells

• (^) Muscle cells comprise the three different types of muscles: skeletal, cardiac, and smooth types. These cells are shaped differently and enable these muscles to help our bodies function properly. Each type of animal cell is specialized to do different jobs.
