---|---|
replication | the cell makes a copy of the DNA in it's nucleus |
mitosis | is the stage during which the cells nucleus divides into new nuclei |
interphase | is the period before cell division occurs |
cytokinesis | completes the process of cell divison |
chromosome | scientists call each doubled rod of condensed chromatin |
chromatid | each identical rod, or strand, of the chromosome |
DNA replication | this ensures that each daughter cell will have all of the genetic information it needs to carry out its activates |
cell cycle | the regular sequence of growth and division that cells undergo |
stomata | carbon dioxide enters the planet through small openings on the undersides of the leaves |
fermentation | an energy-releasing process that does not require oxygen |
autotroph | an organism that makes its own food |
pigment | colored chemical compounds that absorb light |
chlorophyll | the main pigment found in the chloroplasts of plants |
comparing photosynthesis and respiration | these two things can be thought of as opposite processes |
heterotroph | an organism that cannot make its own food |
respiration | the process by which cells "withdraw" energy from glucose |
photosynthesis | the process by which a cell captures the energy in sunlight and uses it to make food |
