A Eukaryote is an organism made of eukaryotic cells. 2 of 17 What is a Prokaryote? A Prokaryote is a prokaryotic cell (singe-celled organism). 3 of 17 What is a cell? A cell is the smallest structural and functional unit of an organism. 4 of 17 What is prokaryotic cell? Small and simple cells e.g bacteria. 5 of 17 What is eukaryotic cell? Complex cells that include animal & plant cells. 6 of 17 What is the function of a nucleus? Contains the genetic material and controls all the activities of the cell. 7 of 17 What is the function of cytoplasm? Is a gel-like substance where most of the chemical reactions happen. It contains enzymes which control the chemical reactions. 8 of 17 What is the function of mitochondria? This is where most of the reactions for aerobic respiration takes place. 9 of 17 What is the function of a cell membrane? Controls the movement of substances in and out of the cell. 10 of 17 What is the function of ribosomes? This is where protein is made in the cell. 11 of 17 What is the function of a cell wall? Supports and strengthens the cell (made of cellulose). 12 of 17 What is the function of permanent vacuole? Contains cell sap, which is a weak solution of sugar and salts. 13 of 17 What is the function of chloroplasts? This is where photosynthesis occurs; they also contain a green substance called chlorophyll which absorb the light needed for photosynthesis. 14 of 17 Bacterial cells don't have a 'true' nucleus. What do they have insteac? They instead have a single circular strand of DNA that floats freely in the cytoplasm. 15 of 17 What are plasmids? Small rings of DNA. 16 of 17 What don't bacterial cells have? Mitochondria & Chloroplast 17 of 17
