the process by which the body takes in and uses food
to carry or move from one place to another
the process by which cells break down simple food molecules to release the energy they contain
the process by which wastes are removed from the body
the behaviors and physical characteristics that allow organisms to live successfully in their environments
process by which plants and some other organisms use light energy to convert water and carbon dioxide into oxygen and high-energy carbohydrates such as sugars and starches
green pigment that captures light energy for photosynthesis
organelle found in cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy
membrane discs containing plant pigments; coin-like structures
stacks of thylakoids
The fluid of the chloroplast surrounding the thylakoid membrane; involved in the synthesis of organic molecules from carbon dioxide and water.
has a yellow-orange color and is primarily found in the palms and the soles
the form of sugar that circulates in the blood and provides the major source of energy for body tissues. When its level is low, we feel hunger.
the small openings on the undersides of most leaves through which oxygen and carbon dioxide can move
the layer of cells in a leaf where most photosynthesis occurs
proces in which protozoans digest tthei r food. Lyosomes enclose themeselves arounda food particle and release digestive enzymes. Unusuable products are taken out of the vaucole
digestion that takes place outside of the cell
extensions of cytoplasm for movement and feeding
process in which extensions of cytoplasm surround and engulf large particles and take them into the cell
a state of balance
process by which a cell takes in liquid from the surrounding environment
Short-term, repetitive, or cyclical movements that recur on a regular basis.
process by which cells release energy in the absence of oxygen
streaming movement within cell that allows for transport in the cytoplasm
Respiration that does not require oxygen
Respiration that requires oxygen
iron-containing protein in red blood cells that carries oxygen for delivery to cells
Conditions in the environment that put limits on where an organism can live
a stable mature community that undergoes little or no change in species over time
the series of predictable changes that occur in a community over time
largest number of individuals of a population that a environment can support
