Cell Structure Flashcards
function of NUCLEUS
contains DNA to control cells activities
function of CYTOPLASM
a gel-like substance where most of the cells chemical reactions take place. it contains enzymes which control these reactions.
function of CELL MEMBRANE
forms the outer surface of the cell and is partially permeable so controls which substances go in and out
function of CELL WALL
(only in plants) a rigid structure made of cellulose which surrounds the cell membrane. it SUPPORTS and STRENGTHENS the cell
function of MITOCHONDRIA
small organelles where most reactions for AEROBIC RESPIRATION TAKES PLACE. respiration transfers energy that the cells needs to work
function of CHLOROPLASTS
site of photosynthesis. contain a green pigment CHLOROPHYLL which is used in photosynthesis.
function of RIBOSOMES
small organelles where proteins are made in the cell
function of PERMANENT VACUOLE
a large organelle that contains cell sap. it helps to SUPPORT THE CELL.
