- membrane-bound sacs move these substances in and out of cells (like a vacuole?)
- Vessicles
- greater concentration of solutes higher than cell solute
- Hypertonic
- Process by which a cell takes in material into the cell by infolding of the cell membrane "brings into cell"
- Endocytosis
- When comparing 2 solutions, the solution with the lesser concentration of solutes Lower than cell solute
- Hypotonic
- Process by which a cell releases large amounts of material "takes out of cell"
- Exocytosis
- equal to cell solute concentration is the same
- Isotonic
- moves large molecules with help from carrier proteins movement of specific molecules across cell membrane through protein channels
- Facilated Diffusion
- takes in fluids process by which a cell takes in liquid from the surrounding environment
- Pinocytosis
- extensions of cytoplasm surround a particle & package it within a food vacuole takes in cells, fragments, organic molecules
- Phagocytosis
- identifies solutions with hypotonic, isotonic & hypertonic diffusion of water through a selectively premeable membrane
- Osmosis
- process by which molecules tend to move from an area where they are more concentrated to an area where they are less concentrated
- Diffusion
- Passive transport goes down.... Active transport goes against...
- Concentration Gradient
- energy-requiring process that moves energy across a cell membrane against a concentration difference goes against concentration gradient (ex. climbing up staircase-more energy required)
- Active Transport
- 1 of the 2 things movement through a membrane is achieved by goes down concentration gradient movement of a substance down concentration gradient (ex. walking down staircase-less energy) no energy
- Passive Transport
- moves ions & small channels
- Protein Channels
- water liking (POLAR) -head
- Hydrophillic
- water breaking (Non-Polar) -tail
- Hydrophobia
- active transport uses membrane packaging in... movement through vessicles
- Bulk Movement
