(21 cards)
Describe prokaryote
No nucleus or other membrane bound organelles
All bacteria
Describe eukaryote
Have membranes, ribosomes, and cytoplasms.
What do prokaryotes and eukaryotes have in common
Both have cell membrane and cytoplasms and ribosomes
Does passive transport require energy
No
Do molecules move with or against the concentration gradient in passive transport?
With
Do molecules move from low to high concentration or high to low concentration in passive transport?
High to low
Study this!!!!
Study the diffusion, osmosis, and facilitated diffusion chart.
Describe a solution that has less solute than a cell.
Hypotonic
Describe a solution that has more solute than a cell.
Hypertonic
Describe a solution that has the same amount of solute as the cell.
Isotonic
Define lyse
When a cell bursts
What cell structure protects a cell from lyse
Cell wall
In which type of solution will a cell shrink
Plasmolysis
In which type of solution will a cell burst or lyse
Osmosis
Does active transport require energy
Yes
Do molecules move with or against the concentration gradient in active transport
Against
Do molecules move from high to low or low to high during active transport
Low to high
What is endocytosis
Large molecules and liquids are taken in the cell when the cell membrane makes a pocket around them.
Compare phagocytosis and pinocytosis
Phagocytosis- eating cells
Pinocytosis- drinking cells
What is exocytosis
Materials are released out of the cell through the cell membrane with the help of a vesicle.
What is the cell theory
All living things are made of cells
All living things are produced by other living things
The cell is the most basic unit of life
