What is a tiny structure inside a cell that has a specific job/function for the cell?
solution with a lower water concentration of dissolved particles
what is hypertonic?
The tails are _________ while the head is _________.
hydrophobic, hydrophilic
These processes require ATP
What is active transport?
In order for digestion to be balanced the content has to be
hypo, hyper, or iso?
What is isotonic?
the outer part of a plant cell that gives it its support?
What is the cell wall?
a solution with a higher water concentration of dissolved particles
What is hypotonic?
protein maintaining the stability and structure of the cell membrane and the shape of a cell
What is a spectrin
Processes such as osmosis, simple diffusion, and filtration
What is passive transport?
Why are most cells subjected to osmosis?
what is mostly surrounded by water?
This controls the center of the cell, directs all its activities
What is the nucleus?
true or false? the cell changes in volume when placed in an isotonic solution.
what is false?
The part of a membrane protein that extends through the phospholipid bilayer is primarily composed of amino acids that are
( hint: polarity)
nonpolar
these channels use ATP to move molecules across a membrane.
What are carrier proteins?
Cell body shrinks and pulls away from the cell wall
What is plasmolysis?
what are peroxisomes?
What happens to a person who is injected with potassium chloride?
( what happens to their cells?)
Their cells shrink from a hypertonic solution causing them to suffocate from deoxygenated blood cells.
While water continually orients phospholipids into a lipid bilayer, it does not fix the lipids permanently into position. The bilayer is considered to be
What is fluid?
A process that involves transporting molecules into eukaryotic cells to form a vacuole
What is Endocytosis?
The process of releasing things out of cells and the process of taking substances into cells
What are endocytosis and exocytosis?
prokaryotic movement is attributed to blank while eukaryotic movement is attributed to by
What is flagella, and what is the cytoskeleton?
A plant cell is turgid when putting it in this type of solution
What is hypotonic?
Formed when the concentration of a molecule is different on two sides of a membrane
What is a concentration gradient?
a protein that opens channels to allow two molecules to enter a cell simultaneously
What is a symporter?
Proteins that allow water molecules to get past the hydrophobic middle of a membrane
What are aquaporins?
