Cell Organelles

• A cell is like a factory. It has many machines inside to make it work correctly.

• The “machines” in a cell are called organelles

• Organelles perform functions to keep a cell healthy and alive.

• They are similar to organs which perform functions to keep a body healthy and alive.

Nucleus-control center of the cell

•Nuclear membrane – outer covering of the nucleus, protects the nucleus

• The Nucleus contains chromosomes with DNA.

• The DNA determines the cell’s activities.

• The DNA determines an organism’s traits.

Cell membrane – outer covering of the cell

• Jobs of membrane:

1. Protection

2. Selectively Permeable – Controls what goes in and out of cell.

Cytoplasm – jelly like liquid that holds all of the

organelles

Mitochondria

• “Power House” of the cell.

• Supplies the cell with ATP energy

Ribosome

•Produces proteins

Vacuole – storage binsStores water and waste

materials

Golgi Bodies

• “Packing and Shipping”

• Pack and ship materials to other parts of the cell

Endoplasmic Reticulum

“Intracellular Highway”

•Transport tubes

•Pathway of tubes that carry substances in the cell

Plant Cells

• Plant cells have 3 parts that animal cells do not.

• 1. Cell wall

• 2. Chloroplast

• 3 Large Central Vacuole

Cell Wall• Outer rigid

protective layer of a plant cell

• The cell wall is outside of the cell membrane

Chloroplast

• Has chlorophyll

• Performs

Photosynthesis
