General Awareness -Biology- Life Processes
Tissues present in leaf
1-Autotrophic organisms synthesize their own food.
2-The process in which energy stored in Carbohydrates released is known as Respiration.
3-Oxygen is released during photosynthesis.
4-Iodine can be used to test the presence of Starch.
5-Photosynthesis occurs in chloroplasts parts of the cell.
6-Plants are green because they reflect green light.
7-The openings present in the epidermis layer of leaf are called stomata.
8-Stomata in large numbers are present in ventral side of the leaves.
9-The inorganic element of the chlorophyll is Magnesium.
10-The substance assimilating Carbon di-oxide in the dark reaction of photosynthesis is Ribulase 1-5 diphosphate.
11-Stroma and Granna are the parts of chloroplasts.
12-Melvin Calvin got Nobel prize for his studies on carbon fixation.
Melvin Calvin
13-Photosynthesis occurs at a higher rate in Red radiation.
14-Food factories of the plants are leaves.
15-Quantum is the energy present in the photon particles of Light rays.
16-The pigments of the leaf are excited during photosynthesis by sunlight.
17-Oxygen during photosynthesis is released from the split of water.
18-KOH effectively absorbs Carbon di-oxide.
19-Light reaction occurs in grana part of chloroplast.
20-Percentage of Carbon-dioxide in the atmosphere is 0.03.
21.Colour of Xanthophyll in plants is yellow.
22-Number of Carbon atoms in Glyceraldehyde-3 phosphate is 3.
23-Chloroplasts are richly present in Palisade parenchyma.
24- Nature of the substance in the stroma is viscous.
25-Stomata help in regulating exchange of gases and evaporation of water.
26-First stable product formed during photosynthesis after absorbing carbon dioxide is Phosphoglyceric acid-PGA.
27-Light reaction of photosynthesis is also named as Hill Reaction.
28-Dark reaction occurs in stroma part of chlorophyll.
29-Orange coloured pigments in plants is Carotene.
30-Photosynthesis is most important life process.
