|
cytoplasm
|
double membrane with pores; present in eukaryotic cells but not prokaryotic
|
|
|
mitochondrion
|
organelle of plant and animal cells involved in release of energy from nutrients by celluar respiration; sometimes celled the "powerhouse of the cell"; contains a little DNA
|
|
|
Ribosome
|
very tiny structure made of RNA and protein; job is to link amino acids together to assemble
|
|

leucoplast
|
clear plastid used to store starch in a plant cells such as potato cells; appears to have concentric rings within; stains dark blue when iodine is applied
|
|
|
Cell membrane
|
portion of cell between necular membrane; sometimes called the sap
|
|
|
lysosome
|
membranous sac-like organelle filled with digestive enzymes to digest ingested particles or worn out cell structures
|
|
|
Vacuole
|
sac like membranes structure which stores food particles in animal cells and stores mainly water and salts in plant cells

starch
|
|
|
enzymes
|
speed up specific reactions without being used up by lowering the necessary activition energy
|
|

|
|
|
the light independent reactions (dark reactions) occur where
|
stroma of chloroplasts
|
|
|
the debate over the source of oxygen (O2) given off by plants during photosynthesis was finally settled by
|
giving plants water containing O-18 and finding that the molecular oxygen released was composed of 0-18
