the smallest unit that is able to perform the basic functions of life
organisms with one cell
organisms with two or more cells
a cell that lacks a nucleus and other organelles, with DNA that isn't organized into chromosomes.
a cell in which the genetic material is enclosed within a nucleus, surrounded by its own membrane.
a thick, gelatin-like material contained within a cell membrane. (most of the work is carried out in the cytoplasm)
a structure of a cell that is enclosed by a membrane and that performs a particular function
contains genetic material to reproduce and function
contains, in plants, chlorophyll
stores supplies in cells
releases energy by using oxygen to breakdown sugar
a group of similar cells that are organized to do specific jobs
structure in a plant/animal cell made of different tissues collaborating to perform particular functions
a group of organs forming an organism
a type of molecule made of subunits of sugar and is used for energy and structure
a molecule made of amino acids controlling cell activity, growth, and repair.
a molecule made of fatty acids, used to store energy.
a major sugar energy source for most cells
an odorless white sugar in carbohydrates
process by which plants absorb sunlight to produce glucose and energy
thin layer at the top made of wax
prevent water from entering at top and bottom
upper leaf part where most of photosynthesis occurs
under palisade mesophyll creating airspace for gases to move
lets gases diffuse in and out of leaf
contain chloroplasts and allows guard cells to open and close
transports food from special tissues and veins
the process by which energy stored in food is turned into usable energy. (C6H1206 + 602 = 6C02 + 6H20 + "usable energy")
extra storage of glucose
use of oxygen in mitochondria
no use of oxygen by fermentation
ATP. usable energy to cell
movement of materials through a membrane without energy
a substance moving from an area of high concentration to an area of low concentration.
movement of water through a membrane from an area of high concentration to low concentration
movement of materials through a membrane with energy
