Apologia Biology 2Nd Edition Mod 6

Front 1

Microtubles

Back 1

Spiral strands of protein molecules that form a tubelike structure

Front 2

Pinocytic vesicle

Back 2

Vesicle formed at the plasma membrane to allow absorption of large molecules

Front 3

Nuclear membrame

Back 3

A highly-porous membrane that separates the nucleus from the cyoplasm

Front 4

Chromatin

Back 4

Clusters of DNA, RNA, and proteins in the nucleus

Front 5

Cytoskeleton

Back 5

A network of fibers that holds the cell together, help the cell to keep its shape, and aids in movement

Front 6

Microfilaments

Back 6

Fine, threadlike proteins found in the cell's cytoskeleton

Front 7

Intermediate filaments -

Back 7

Threadlike proteins in the cell's cytoskeleton that are roughly twice as thick as microfilaments

Front 8

Phosphilipid

Back 8

A lipid in which one of the fatty acid molecules has been replaced by molecules that contains a phosphate group

Front 9

Passive transport

Back 9

Movement of molecules through the plasma membrane according to the dictates of osmosis of diffusion

Front 10

Active transport

Back 10

Movement of molecules through the plasma membrane (typically opposite the dictates of osmosis or diffusion) aided by a process that requires energy

Front 11

Isotonic solution

Back 11

A solution in which the concentration of solutes is essentially equal to that of the cell which resides in the solution

Front 12

Hypertonic solution

Back 12

A solution is which the concentration of solutes is greater than that of the cell that resides in the solution

Front 13

Plasmolysis

Back 13

Collapse of a walled cell's cytoplasm due to a lack of water

Front 14

Cytolysis

Back 14

The rupturing of a cell due to excess internal pressure

Front 15

Hypotonic solution

Back 15

A solution in which the concentration of solutes is less than that of the cell that resides in the solution

Front 16

Activation engery

Back 16

Engery necessary to get a chemical reaction going
