what structure allows substances to move in and out of cell
cell membrane
where do we place our eye during observation
ocular tube/lens
give the flow of sensitivity reaction
receptor--> spinal cord --> brain --> spinal cord --> muscle/effector

constant
manipulated
responding
what are the organs that can be transplanted give 5
lungs, heart, skin, kidney, uterus, liver, blood,
where does most chemical reaction happens in the cell for both plant and animal cells
cytoplasm
why do we add chemicals or dye before we view the cell
so we could observe the specimen clear and the cell will be stained
