Chemical process by which plants use light energy to make sugar from water and carbon dioxide.

Cellular Respiration

Process in cells by which oxygen is chemically combined with food molecules and energy is released.


Adenosine Triphosphate, the major energy-carrying molecule of the cell.


Simple sugar made by plants through the process of photosynthesis.


Green pigment in plants that captures the energy of sunlight for use in photosynthesis.


A structure in a plant cell that contains chlorophyll.

Photosynthesis Equation

6CO2 + 6H2O -> C6H12O6 + 6O2

Cellular Respiration Equation

C6H12O6 + 6O2---> 6CO2 + 6H2O + ATP

Cell membrane

Outermost layer of the cell that controls the movement of substances into and out of the cell.


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


Structure near the center of a cell that contains the cell's DNA


A structure located in the nucleus of a cell, made of DNA.


Segment of DNA, found on a chromosome, that determines the inheritance of a particular trait


The material found in the cell's nucleus, that determines the genetic traits of the organism


Structures in the cell that transform the energy in food into a form cells can use to carry out their activities.


Fluid-filled structure that holds waste products or substances needed by the cell.


Small round structures found in the cytoplasm that contain digestive enzymes. Usually not found in plant cells.


Structure in a cell where proteins are put together

Endoplasmic Reticulum

Structure in a cell that is involved in making proteins and transporting materials.

Golgi body

Cell structure that helps package and distribute products with-in the cell


small membrane-bound sac that functions in moving products into, out of, and within a cell

Cell wall

Stiff outer barrier of a plant cell, outside the cell membrane, which is made mostly of cellulose


One-celled organism that does not have membrane-bound nucleus or organelles.


Organism made up of cells that have a membrane-bound nucleus and other organelles


Allowing substances to pass or diffuse through. Pores are the widest and it is not very selective.


Preventing substances from passing or diffusing through. Pores are the smallest and it is very selective.


membranes that allow some substances through but not others.


diffusion of water through a selectively permeable membrane


the process by which molecules move from an area of higher concentration to an area of lower concentration

Active Transport

the movement of materials through a cell membrane using energy
