DID YOU KNOW THAT.................

1. Nucleus - contains DNA
2. Nucleolus - in nucleus, manufactures ribosomes
3. Endoplasmic reticulum - move materials from one part of the cell to another
4. Golgi apparatus - where proteins are converted to their final form
5. Lysosomes - contain digestive enzymes
6. Chloroplasts - contain pigments important to photosynthesis
7. Mitochondria - site of ATP production
8. Ribosomes - manufacture of proteins
9. Centrioles and microtubules - support, cell locomotion, forming spindle in nuclear division
10. Cell wall - support, prevents cell from bursting by taking in too much water
11. Osmosis: the net movement of water molecules through a partially permeable membrane from an area of higher water potential to an an area of lower water potential.
12. Facilitated diffusion: This is where polar molecules are transported across membranes. Molecules bind with transport proteins which change shape and move the molecules across the membrane. No metabolic energy is required.
13. Examples of active transport: the calcium pump (skeletal muscles), the sodium-potassium pump (nerve cells).
14. Endocytosis: An active process whereby substances are taken into the cell by infoldings of the surface membrane. (Exocytosis is similar.)
15. Mitosis: Mitosis is a type of cell division where the daughter cells have the same number of chromosomes as the parent cell and are genetically identical to the parent cell. Mitosis takes place in four stages: prophase, metaphase, anaphase and telophase.
16. During prophase, each chromosome forms two chromatids joined by a centromere. Two centrioles begin to move forming a spindle and the nuclear envelope breaks down.
17. During metaphase, the chromosomes are attached to the spindle fibres and line up at the equator of the cell.
18. During anaphase, the centromeres split and the chromatids are pulled to opposite poles of the cell.
19. During telophase, the nuclear envelope reforms and the cell membrane narrows at the middle, forming two daughter cells 
20. Sucrose = glucose + fructose; main form in which carbohydrate is transported in plants 
21. Maltose = 2 glucose; found in some germinating seeds eg barley
22. Lactose = glucose + galactose; found in milk
23. Lipids - insoluble in water, soluble in organic solvents
24. Fats & oils - compounds of glycerol and fatty acids
25. Structure of proteins 

• Primary - Order of the amino acids
• Secondary - The way the chain folds/turns on itself due to hydrogen bonding
• Tertiary - Cross-links including hydrogen bonds, inonic bonds and sulphur bridges
• Quaternary - The arrangement of two or more polypeptides eg haemoglobin

26.Collagen - fibrous protein; great tensile strength; found in bones, tendons, skin etc; structure = triple helix
27.Insulin - globular protein, folded chain held together by 2 disulphide bridges with the loop removed
