cell notes
cell structures and function
structure | funtion |
---|---|
cell wall | -animals don't have one -plants:made of cellulose -gives strength to plant thru turgor pressure |
cell membrane | -Cell Membrane is the outside covering of a cell that is flexible but still provides support. It determines what goes in and out of the cell such as water, ions, oxygen, CO2 and nutrients. |
Vacuole | - storage unit in cells that hold water. small in animal cells |
nucleus | control center of the cell, houses DNA, controls cell growth and makes ribosomes |
lysosome | contains digestive enzymes to break things down in the cell |
Mitochondria | - "powerhouse" of the cell. Produces energy by breaking down glucose |
Cytoplasm | - gelatinous "goo", semi-transparent fluid that fills the cells. Organelles are suspended in it |
Rough ER | - covered in ribosomes, stores proteins |
Smooth ER | - transports cell products |
Ribosome | - Site of protein synthesis (makes protein) |
Golgi Body | - Packages cell products for transport (like ups) |
site of photosynthesis turns light in to energy has chlorophyll |
