Eukaryotic Cell Structure Most organisms are eukaryotes.

Cell Wall found in plants, algae, fungi, bacteria Rigid; protects and supports contains cellulose for structure surrounds cell membrane Cell Membrane

Animal Cell cytoplasm cell membrane nucleolus chromatin nuclear

Plant Cell nucleus nucleolus chromatin cell wall cytoplasm nuclear membrane cell wall cell membrane cytoplasm

Types (both in all cells): smooth E R – lipid synthesis, neutralizes poisons

2. rough E R – has ribosomes, transports protein

Ribosomes site of protein synthesis found on rough E.R. and free floating in the cytoplasm

Animal Cell cytoplasm cell membrane smooth ER nucleolus chromatin ribosome rough ER nuclear membrane

Plant Cell nucleus nucleolus chromatin smooth ER cell wall rough ER nuclear membrane cell wall cell membrane rough ER ribosome cytoplasm

Golgi complex packages and distributes protein vesicle packages and distributes protein forms small membrane sacs known as vesicles

Mitochondrion “power house” respiration centers of cell (breaks down glucose to release stored energy)

Mitochondrion produces energy (ATP) structure – inner folded membrane for more surface area = more energy produced

have there own DNA can divide to make more energy ex: muscle cells have large amounts of mitochondria because they need a lot of ATP

Chloroplasts found in plant and algae cells contain a green pigment called chlorophyll where photosynthesis takes place

Animal Cell cytoplasm cell membrane smooth ER nucleolus chromatin ribosome mitochondria rough ER nuclear membrane Golgi complex

Plant Cell nucleus nucleolus chromatin smooth ER chloroplast cell wall nuclear membrane Golgi complex cell wall cell membrane rough ER mitochondria ribosome cytoplasm

Lysosomes “suicide sacs” vesicles which contain digestive enzymes

digests food particles, kills bacteria, destroys worn out cells and organelles, degenerates tissue found in animal cells

White blood cells have a lot of lysosomes to digest bacteria.

Vesicles small sacs used to transport material around the cell

Vacuole large storage compartments for enzymes, waste, water, sap found in plant cells

Animal Cell vesicle cytoplasm cell membrane smooth ER nucleolus chromatin ribosome mitochondria rough ER nuclear membrane Golgi complex lysosome
