3rd Nine Weeks Flashcards
What happens during Interphase
DNA is replicated
What happens at the end of Cytokinesis
Two identical cells are created
What happens during Propase
Nuclear membrane disintegrates, nucleolus disappears, chromosomes condense, mitotic spindle forms
What is the function of the plasma membrane
controls what enters and leaves the cell
What do carbohydrate chains in the plasma membrane do
Helps identify chemical signals outside the cell, cell to cell recognition
What does cholesterol do
Helps to stabilize the membrane
What is diffusion
Movement of molecules from an area of high concentration to an area of low concentration
What is osmosis
Diffusion of water
Hypertonic solution
High amounts of solute
Hypotonic solution
Low amounts of solute
Active Transport
Movement of molecules against the concentration gradient; cost energry.
Two examples of active transport
exocytosis and endocytosis
Photosynthesis
Anabolic, builds glucose and releases oxygen
Where does Phase 1 occur
Thylakoids
What happens in Phase 1
Light dependent, water molecule splits, ATP and NADPH are released into the stroma for Stage 2
