Plasma Membrane
The function of the cell membrane
regulates the entrance and exit of molecules into/out of the cell
These structural proteins are found on only one side of the plasma membrane
peripheral
When something can pass through the membrane, it is said to be ________
permeable
diffusion of water from an area of higher concentration to lower concentration across a semipermeable membrane
Osmosis
Organelle involved in photosynthesis
Chloroplast
This lipid makes up the majority of the plasma membrane
phospholipid
These proteins span across the plasma membrane
integral proteins
____________, ______________molecules can pass freely across the plasma membrane
Small, uncharged
If a cell is in a hypertonic solution the water will flow_________
Out of the cell
Organelle involved in cellular respiration
Mitochondria
The polar heads of the phospholipid have this relationship with water
Water-loving (hydrophilic)
A protein with sugar molecules attached to it - important in cell signalling
Glycoprotein
Moving from an area of high concentration to an area of low concentration is moving which direction on what
Down the concentration gradient
The pressure that develops in a system due to the water concentration gradient
Osmotic pressure
Organelle involved in protein synthesis
Ribosomes
Polar tails of a phospholipid have this relationship with water
hydrophobic
Channel protein
This is the movement of a solute from an area of high concentration to an area of low concentration
Diffusion
If a cell is in a hypotonic solution the water will flow
Into the cell
Organelle that fills up with water (turgor)
Vacuole
cholesterol
Type of diffusion that requires a channel protein
Facilitated diffusion
Large molecules, ions, and charged molecules require one of these to move across a membrane
Channel proteins, Carrier proteins bulk transport (Vesicle formation)
When a cell shrivels
crenation/plasmolysis
Nucleolus
