The background material of the mitochondrion; it is the site of the stages of aerobic respiration (called the Krebs cycle) (6) 6. a functionally and structurally distinct part of a cell. For example, a ribosome or mitochondrion (9) 7. a short, microscopic, hair like vibrating structure. They occur in large numbers on the surface of certain cells, either causing currents in the surrounding fluid, or, in some protozoans and other small organisms, providing propulsion (5) 10. the DNA in the nucleus when the chromosomes have not condensed (9) Down 2. a cell that does not contain a nucleus or any other membrane bound organelles; bacteria is an example (11) 3. a structure that is present outside the plasma membrane in plant cells, fungal cells and bacterial cells; in plants it is made of criss-crossing layers of cellulose. (4, 4) 4. molecules made from chains of amino acids and sugars; they are found in bacterial cell walls (13) 7. a space enclosed by the membranes of the endoplasmic reticulum (8) 8. the cell surface membrane, made up of the phospholipid bi-layer in which protein molecules can float (6, 8)
