Exploring Creation With Biology Flashcards

Activation Energy

Energy necessary to get a chemical reaction going

Active Transport

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

Cell Wall

A rigid substance on the outside of certain cells, usually plant and animal cells

Central Vacuole

A larger vacuole that rests at the center of most plant cells and is filled with a solution that contains a high concentration of solutes


Clusters of DNA,RNA, and proteins in the nucleus of a cell


Organelles that contain pigments used in photosynthesis


The rupturing of a cell due to the excess internal pressure


A jellylike fluid inside the cell in which the organelles are suspended

Cytoplasmic Streaming

The motion of cytoplasm in a cell that results in coordinated movement of the cell's contents


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

Endoplasmic Reticulum

An organelle composed of an extensive network of folded membrane that performs several tasks within a cell

Golgi Bodies

The organelles where proteins and lipids are stored and then modified to suit the needs of the cell

Hypertonic Solution

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

Hypotonic Solution

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

Intermediate Filaments

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

Isotonic Solution

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


Organelles that store starches or oils


The organelle in animal cells responsible for hydrolysis reactions that break down proteins, polysaccharides, disaccharides, and some lipids


Fine, threadlike proteins found in the cell's cytoskeleton


Spiral strands of protein molecules that form a tubelike structure


The organelles in which nutrients are converted into energy

Nuclear Membrane

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

Passive Transport

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

Phagocytic Vacuole

A vacuole that holds the matter which a cell engulfs


The process by which a cell engulfs foreign substances or other cells


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

Pinocytic Vesicle

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

Plasma Membrane

The semipermeable membrane between the cell contents and either the cell wall or the cells surroundings


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


Non-membrane-bounded organelles responsible for proteins synthesis

Rough ER

ER that is dotted with ribosomes

Secretion Vesicle

Vesicle that holds secretion products so that they can be transported to the plasma membrane and released

Smooth ER

ER that has no ribsomes

Waste Vacuoles

Vacuoles that contain the waste products of digestion
