CA3 Flashcards
Movement from an area of high [] to low []
Passive
Diffusion and osmosis are good examples
Passive
Requires the use of energy
Active
Moves from an area of high [] to an area of low [] without the help from proteins or energy from the cell
Passive
Allows the cell to obtain glucose and amino acids
Active
The process of engulfing/taking in particles for use in the cell (endocytosis)
Active
The process of releasing materials out of the cell
Active
What is osmosis
Osmosis is water particles moving across a semi permeable membrane
What are 3 differences between active and passive transport
Active Is movement from [low] to [high]. Passive is [high] to [low]. Active transport requires energy passive doesn’t. Active transport has movement of particles across a cell membrane, passive has water across a semi-permeable membrane
What is a prokaryote
No nucleus, small, has ribbons, no membrane bound organelles, no cytoskeleton, no meiosis
What is hypertonic
Lots of movement, water moves out of object
What is hypotonic
Less movement, water goes into object
What is active transport
Movement from [low] to [high]
No dynamic equilibrium
Energy required
Against [] gradient
What is osmosis
No energy required
With the [] gradient
Movement from [high] to [low] until dynamic equilibrium Energy required
Movement of water across a semi permeable membrane
