Presentation transcript:

Cell structure – form and function

The cell as a factory The nucleus

Cellular Control Center Contains all genetic information in the form of DNA. /watch?v=uohe2V4yOzE /watch?v=uohe2V4yOzE

Storage, clean up, and support Vacuoles and vessicles Lysosomes Cytoskeleton

Vacuoles Store food, water, or waste materials

Lysosomes Contain digestive enzymes to digest unwanted particles nimations/flythrough/m ovie-flash.htm nimations/flythrough/m ovie-flash.htm

Cytoskeleton Maintain cell shape Move materials within the cell Microfilaments – support Microtublues – shape, movement

Cytoplasm Clear fluid within cell that contains all organelles

Building proteins Ribosomes Endoplasmic reticulum Golgi apparatus

Ribosomes Makes proteins in the cell May be free in cytoplasm or attached to ER

Endoplasmic Reticulum Series of folded membranes that form sacs or tubes Rough ER has ribosomes attached

Golgi apparatus Saclike membranes used for storing/ packaging of chemicals m/watch?v=a6boqEbcJ WI m/watch?v=a6boqEbcJ WI

Capturing and releasing energy Chloroplasts Mitochondria

Energy center – ATP produced in cellular respiration

Chloroplast Only found in plants/ algae Chloroplasts contain the pigment chlorophyll

Cell boundaries Cell membrane Cell wall

Cell Boundaries Cell membrane – phospholipid bilayer Controls what enters and leaves the cell

Cell Wall Found in plant cells Adds protection and support.
