Requires the cell to use energy - T or F
TRUE - the cell has to use ATP energy to move material through active transport.
Requires the cell to use energy. T or F
False - Passive transport requires no ATP energy from the cell.
How many layers is the cell membrane?
bilayer or 2
A solution with equal concentrations of water and solutes compared to a cell?
Isotonic solution
Why won't plant cells "pop" when taking in a lot of water?
Their cell walls
Bulk movement of materials out of a cell.
Exocytosis
Movement of molecules from a high concentration to a low concentration.
Diffusion
What is another name for the cell membrane?
Plasma membrane.
Also known as a Fluid mosaic model
A solution with more solutes than water compared to a cell.
Hypertonic Solution
Hydrophillic (water-loving) heads and hydrophobic (fears water) tails
What is the phospholipid bilayer
Bulk movement of materials into a cell.
Endocytosis
Movement of water from a high concentration to a low concentration through a membrane.
Osmosis
The cell membrane can mostly choose what can enter and leave the cell. What do we call this?
Selectively permeable.
A solution with more water than solutes compared to a cell.
Hypotonic solution
Plants love what kind of solution?
Hypotonic
Bulk movement of liquid into a cell. Sometimes referred to as "cell drinking"
Pinocytosis - Form of Endocytosis
Sped up diffusion where the cell uses channel proteins.
Facilitated diffusion.
What molecule did we say the cell membrane CANNOT control the passage of?
Water
What is known as cell shrinking do to losing water?
Plasmolysis
Our cells love what kind of solution?
Isotonic
Active transport that pumps ions against their concentration gradient. Classic example!
Sodium Potassium pump
Molecules move from high to low until they reach what? Technically they never stop moving so we have a two word answer for this!
Phospholipids
Choleserol
Proteins
Glycoproteins
What is known as cell splitting or popping due to too much water coming in?
Cytolysis
The water pressure inside a plant cell.
Turgor pressure
