1 starch - carbohydrate and consists of many glucose.
         carbon fixation reactions , the chemical reactions in the darkness.
2 Entomophily - pollination in plants by insects transferring pollen

3 nicotonic acid perhaps, and ascorbic acid - c vitamin
  
4 salt marshes, probably

5 dispersal

6 pea

7 auxiliary buds, probably.

8
cleistogamous

9  I am not sure. insectivoros plants get proteins from insects, also fat, ?

10  Nitrates

11  nectories..  perhaps all the above.

12

13 magnesium

14  dixon.  but there is some mention that JC Bose also proposed that.

15  photolysis

16 PGAL 3-phosphoglyceraldehyde

17 thylakoids perhaps.  not sure. confusion with chloroplast

18 pyruvic acid

19 mitochondria

20. potometer
