Cells Flashcards
Nucleus
contain genetic material
Cytoplasm
where chemical reactions take place
Cell membrane
controls what goes in and out
Mitochondria
where respiration takes place
Ribosomes
protein are made
Cell wall
made of cellulose- strengthens cell
Diffusion
particles moving from an area of high concentration to an area of low concentration.
Small molecules that can diffuse through cell membranes
glucose, oxygen and amino acids
Big molecules that can’t fit through cell membranes
starch and protein
Palisade Cells

Red blood cells
carry oxygen
packed with haemoglobin
no nucleus
Sperm Cell

streamlined head
many mitochondria
Muscular Tissue
