Cell Biology

5. The organelle associated with membrane production, has ribosomes on its surface.
7. Small spherical body within the nucleus that manufactures ribosomal RNA and assembles ribosomes.
12. Nine triplets of microtubles arranged in a ring, which aid cell division.
14. Found within a plant cell, in addition to its cell membrane.
15. An outer membrane enclosing a semi-fluid matrix, throughout which is an internal membrane folded into 'cristae'
16. The part of the cell where DNA is retained.

1. Animal and plant cells containing DNA and organelles.
2. The semi-liquid medium in which the organelles float.
3. Elaborate 3D system of folded membranes spreading through the cytoplasm.
4. Semi-permeable double layered sheet of lipid molecules, interspersed with protein.
6. The microscopic structures within a cell that perform metabolic processes.
8. Specialised vesicles containing digestive enzymes which destroy unwanted materials within the cell.
9. Sorts, packages and sends cellular material to it's correct destinations within the cell.
10. "The smallest structural and functional unit of an organism".
11. A closed sac that transports cellular material.
13. Aid protein synthesis and carry proteins around the cell.
