Cell Organelles S 7 L 2: Cell Structure and Function

CELL ORGANELLES • Organelles: Structures within a cell with special functions.

CELL ORGANELLES • Organelles: Structures within a cell with special functions.

Cell Wall (School Walls) • Cell Wall- Strong, rigid wall that protects the cell

Cell Wall (School Walls) • Cell Wall- Strong, rigid wall that protects the cell and gives it shape. – Plants cells have cell walls; Animal cells do not.

Cell Membrane (Building Doors) • The outer covering of a cell. • Used for

Cell Membrane (Building Doors) • The outer covering of a cell. • Used for protection and support. • Lets good stuff in; keeps bad stuff out.

Cytoplasm (Air) • A gel-like substance found inside the cell. • Used to support

Cytoplasm (Air) • A gel-like substance found inside the cell. • Used to support the organelles.

Nucleus (Main Office) • Regulates and controls all the activities within a cell. •

Nucleus (Main Office) • Regulates and controls all the activities within a cell. • Contains chromosomes which contain DNAhereditary material

Nuclear Membrane • Covers and protects the nucleus. • Controls what enters or leaves

Nuclear Membrane • Covers and protects the nucleus. • Controls what enters or leaves the nucleus.

Chloroplast (Cafeteria) • Green organelle that makes sugar for plants. • Chloroplast is used

Chloroplast (Cafeteria) • Green organelle that makes sugar for plants. • Chloroplast is used in photosynthesis. • Contain chlorophyll- Green pigment that captures the sun’s light. • Plants contain chloroplast; animal cells do not.

Mitochondria (Generator) • Bean or Rod-shaped organelle that produces ATP (provides energy) by performing

Mitochondria (Generator) • Bean or Rod-shaped organelle that produces ATP (provides energy) by performing cellular respiration. • The POWERHOUSE of

Endoplasmic Reticulum (ER) (Hallways) • A network of passages used to move proteins and

Endoplasmic Reticulum (ER) (Hallways) • A network of passages used to move proteins and other materials throughout the cell. • Comes in two types: Rough (has ribosomes) and Smooth (does not have ribosomes)

Ribosomes (Workers) • Tiny organelles that are used to make proteins. • Some float

Ribosomes (Workers) • Tiny organelles that are used to make proteins. • Some float throughout the cytoplasm, others are stuck to the rough endoplasmic reticulum.

Golgi Body/Complex/Apparatus (Packaging Center/Mail Room) • This large organelle modifies and packages proteins. •

Golgi Body/Complex/Apparatus (Packaging Center/Mail Room) • This large organelle modifies and packages proteins. • It is the “Packaging” center for the cell.

Vacuoles (Lockers) • Organelles that are used for storage. • Vacuoles store food, water

Vacuoles (Lockers) • Organelles that are used for storage. • Vacuoles store food, water and waste.

Lysosomes (Custodians) • Small round organelles that contain digestive chemicals. • Used to break

Lysosomes (Custodians) • Small round organelles that contain digestive chemicals. • Used to break down food, waste and dying organelles.

From Cell to Organism • Groups of cells combine to form tissues. • Groups of tissue combine to form organs.

From Cell to Organism (Cont) • Groups of organs combine to form organ systems.

From Cell to Organism (Cont) • Groups of organs combine to form organ systems. • Groups of organ systems combine to form an organism.
