Cell Organelles: Be able to identify the cell structures of the animal and plant cell! Know the function of each cell structure!

Nucleus Controls all the cell’s activities.

Nuclear Membrane Controls what enters and leaves the nucleus.

Rough ER Smooth ER Transports substances Makes lipids & breaks down toxic substances.

Golgi Apparatus Packages & distributes substances.

Mitochondria Makes energy.

Lysosome Breaks down substances.

Vacuole Stores water, food, waste.

Ribosomes Makes proteins.

Cytoskeleton Provides shape & support.

Cytoplasm Contains or holds cell’s materials.

Cell Membrane Regulates what enters and leaves the cell. Phospholipids

Chloroplast Makes food for the cell.

Cell Wall Provides extra support and protection.

The Animal Cell: Golgi Apparatus Smooth ER Nucleus Rough ER Vacuole Mitochondria Cell Membrane Lysosome Ribosomes Cytoplasm

The Plant Cell: Rough ER Smooth ER Vacuole Nucleus Mitochondria Golgi Apparatus Cholorplast Ribosomes Cytoplasm Cytoskeleton Cell Membrane Cell Wall

Structures used for Motility: Flagella Cilia Long whip-like structure Small hair-like structures

Animal Cell vs. Plant Cell

Practice Questions

Difference between Prokaryote & Eukaryote? 1. Pro – no nucleus Pro – no membrane bound organelles

What does a plant cell have that an animal cell does not? 1. Cell wall 2. Chloroplast

What important organelle helps maintain homeostasis by moving substance from one part of the cell to another part? Rough ER

Cat bone Bacteria Sunflower Human muscle You look under the microscope and see a nucleus, cytoplasm, chloroplast and cell wall. What are you seeing? Cat bone Bacteria Sunflower Human muscle

What structure identifies this cell as a eukaryote? 5 5 Nucleus 1 4 2 3

What is the organelle associated with plant photosynthesis? Chloroplast

What structure does not belong in a prokaryote? DNA Cytoplasm Ribosomes Nuclear membrane

Prokaryote; animal cell Eukaryote; animal cell Prokaryote; plant cell What type of cell is being described; mitochondria, lysosome, cell membrane, nucleus, small vacuole? Prokaryote; animal cell Eukaryote; animal cell Prokaryote; plant cell Eukaryote; plant cell

What is the common function of these structures? attachment motility reproduction Engulfing food Differentiation Slide

Why is each cell shaped differently? They mutated No two cells are alike They perform different functions They changed under osmotic pressure
