Transport
Moves from low concentration to high concentration
Active Transport
protects the DNA that controls the activities of the cell
nucleus
moves water
osmosis
one individual member of a species
organism
the division phase of the cell cycle- 1 cell becomes 2 identical daughter cells
Mitosis
The movement of substance from an area of high to low concentration is called
Simple Diffusion
Makes RNA which make up ribosomes. Surrounds the nucleus
nucleolus
involves a protein channel
facilitated diffusion
set of organs working together for a common function
organ system
spindle fibers form out centrioles, and the nuclear membrane disappears.
prophase
What type of feedback mechanism result in amplification of the response?
positive
moves the entire cell through extracellular fluid in a whip like motion
flagella
move small particles like O2 and CO2
diffusion
set of tissues working together for a common function
organ
chromosomes line up in the middle of the cell
metaphase
What gas would likely move through the phospholipid bilayer the most easily?
CO2, Oxygen
breaks down chemical energy in food to release usable energy in the form of ATP
Mitochondria
Involves a vesicle
group of cells working together for a common function
tissue
chromatids move to opposite ends of the cell
(True or False) A substance that is described as having a high concentration is one that has more solute than solvent.
True
help cells divide by pulling chromosomes apart
Centrioles/Centrosomes
molecular pumps
most basic unit of life that has all the characteristics of life
cell
nuclear membrane reforms around chromosomes, spindle breaks down, and cytokenisis begins
telophase
