- What is a cell?
- A basic unit of life
-
What does the cell theory state?
All living things are made up of cells, cells are ths basic units of structure & function in living things, & new cells are produced from existing cells
-
What do all cells have?
DNA & a cell membrane
-
What are the 2 major parts of a cell?
Nucleus & cytoplasm
-
Why is the nucleus important?
It contains almost all of the cell's genetic info which gives instructions for making proteins
-
Vacuole function
Stores materials (water, salts, proteins, & carbs)
-
Vesticle function
Stores & moves materials between cell organelles
-
Lysosome function
Breaks down lipids, carbs, & proteins (polymers) & used in cell defense
-
Cytoskeleton function
Gives the cell its shape, internal structure, & anchors organelles
-
Why do plant cells need bigger vacuoles than animal cells?
Cell walls make it harder for water & other things to go in & out of the cell
-
Ribosome function
Where proteins are assembled
-
Rough ER function
Refines proteins by putting them in 2, 3, & 4 shapes & sorts/stores
-
Golgi apparatus function
Modifies, sorts, & packages protiens & other materials from the ER for storage in the cell or release
-
Chloroplast function
Captures the energy from sunlight & converts it into food
-
Mitochondria function
Converts chemical energy in food into compounds that are easier for the cell to use
-
Cell wall function
Supports, shapes, & protects the cell
-
Cell membrane function
Regulates what enters the & leaves the cell & protects/supports the cell
-
What are the 2 types of cytoskeleton?
Microtubules & microfilaments
-
What are the 2 types of ribosomes?
Free & bound
-
What does the endomembrane system include?
Nuclear membrane, rough & smooth ER, golgi apparatus, lysosomes, vacuoles, & plasma/cell membrane
-
What are the 3 functions of the smooth ER?
Synthesizes lipids, catabolizes carbs, & detoxifies molecules
