Parts of the Cell Notes Cell Unit

Cell Membrane: • Outer layer of the cell that keeps good stuff inside and

Cell Membrane: • Outer layer of the cell that keeps good stuff inside and bad stuff outside. • Example: The Police officer of the neighborhood

Cell Wall: • Provides structure and support for the cell membrane. • Only in

Cell Wall: • Provides structure and support for the cell membrane. • Only in plants. • Example: Security Guard

Nucleus: • contains the cells’ DNA • is the control center of the cell

Nucleus: • contains the cells’ DNA • is the control center of the cell • Example: Principal’s Office

Cytoplasm: • jelly-like substance that holds organelles inside the cell. • Example: the land

Cytoplasm: • jelly-like substance that holds organelles inside the cell. • Example: the land air

Mitochondria: • Breaks down food to make energy • Example: PE

Mitochondria: • Breaks down food to make energy • Example: PE

Chloroplast: • Makes food using the energy from the sun (photosynthesis). • Found only

Chloroplast: • Makes food using the energy from the sun (photosynthesis). • Found only in plants cells. • Example: Plants in the neighborhood

Ribosomes: • The place where proteins are made. • Example: Kitchen

Ribosomes: • The place where proteins are made. • Example: Kitchen

Endoplasmic Reticulum: • Packages up proteins so they can leave the cell. • 2

Endoplasmic Reticulum: • Packages up proteins so they can leave the cell. • 2 Types: Rough and Smooth – (Rough has ribosomes, smooth doesn’t) • Example: Cafeteria Workers

Golgi body: • Processes and transports materials out of the cell. • Example: Delivery

Golgi body: • Processes and transports materials out of the cell. • Example: Delivery Trucks

Lysosome: • Digests food particles, wastes, and foreign invaders. • Example: Janitors

Lysosome: • Digests food particles, wastes, and foreign invaders. • Example: Janitors

Vacuoles: • Store water, food, and other materials. • Very BIG in plant cells

Vacuoles: • Store water, food, and other materials. • Very BIG in plant cells • Example: Storage Closet

Do Now • Why is the lysosome like a janitor? • Why is the

Do Now • Why is the lysosome like a janitor? • Why is the nucleus like the principal? • Why is the cell membrane like the security guard?
