structure, behavior, or other trait in an organism that helps it to survive in its environment.
the basic building blocks of all organisms. Within cells the basic functions of organisms (converting food into energy and getting rid of waste) are carried out.
thin outer layer of cell that functions like a gatekeeper allowing certain materials in and out of the cell, found in plant and animal cells
tough outer barrier that protects plant cells and give them shape, functions like the security fence, found only in plant cells.
in the mitochondria of a cell O2 is chemically combined with glucose (sugar) to release energy (ATP), CO2, and H2O. Happens in plant and animal cells.
green pigment that captures energy of sunlight and through a chemical reaction (photosynthesis) makes food for the plant, found only in plant cells.
structures in a plant cell that make glucose and oxygen, function like solar panels, found only in plant cells.
genetic structures made of DNA that contain information used to direct cell activity and make new cells, functions like a computer hard drive, found in plant and animal cells.
a type of symbiosis in which one species benefits while the other seems to be unaffected.
gel-like fluid that fills the space in between the organelles, found in plant and animal cells
all the organisms that live in an area together with the nonliving things in the environment.
use oxygen and glucose to transform the energy in food to a form the cell can use through a process called cellular respiration, functions like the power plant of the cell, found in plant and animal cells.
surrounds and protects the nucleus, functions to allow certain materials in and out of the nucleus, found in plant and animal cells.
"little organs" or structures (parts) within a cell that carry out specific functions (jobs) that keep the cell alive.
a type of symbiosis that occurs when an organism called a parasite feeds on the cells, tissues, or fluids of another organism call a host.
chemical process by which plants use light energy to make sugar from water and carbon dioxide.
chemical reaction that combines water and carbon dioxide to make glucose - the simple sugar plants use as food, happens only in plant cells.
attached to endoplasmic reticulum and make copies of proteins for a cell, found in both plant and animal cells
a group of organisms that can mate and produce offspring that in turn can produce more offspring.
