1) What is photosynthesis?
Answer: The process by which plants and other photoautotrophs generate carbohydrates and oxygen from carbon dioxide, water and light energy in chloroplasts.
2) What is the source of oxygen produced during Photosynthesis?
Answer: Water (H2O)
3) What is the source of oxygen in the glucose molecule produced during photosynthesis?
Answer: Carbon dioxide (CO2)
4) In which form is food stored in plants?
Answer: Starch
5) Which plants can't perform photosynthesis?
Answer: Beechdrops, Indian pipes, Rafflesia & other fungi.
6) What is the full form of NADP, ADP, ATP, PGA, RuBP, FAD?
Answer: ADP — Adenosine diphosphate.
ATP — Adenosine triphosphate.
NADP — Nicotinamide adenine dinucleotide phosphate
RuBP — Ribulose biphosphate
PGA — Glycerate phosphate
FAD — Flavin adenine dinucleotide
7) Which animal can perform photosynthesis?
Answer: Euglena, Chrysamoeba, Sea slug.
8) Which place of chloroplast is related to a dark phase of photosynthesis?
Answer: Stroma
9) Which place of chloroplast is related to a light phase of photosynthesis?
Answer: Grana
10) Which metal is present in Chlorophyll?
Answer: Magnesium (Mg)
11) Which non-metals are present in Chlorophyll?
Answer: Carbon, Hydrogen, Oxygen, Nitrogen.
12) What is the other name of Photolysis and why?
Answer: Hill reaction because it's discovered by Robin Hill.
13) Which plant tissue is associated with photosynthesis?
Answer: Mesophile
14) Velamen tissue's are present in which kind of plants?
Answer: Epiphytes
15) Which is the first stable product formed during photosynthesis?
Answer: Phosphoglyceric acid
16) Which phase of photosynthesis is associated with Carbon assimilation?
Answer: Dark phase
17) Which is an example of monosaccharides?
Answer: Glucose
18) What is chlorosis?
Answer: A yellowing of plant tissue due to loss or absence of chlorophyll.
19) What is photoinhibition?
Answer: The inhibition of photosynthesis caused by protein damage due to high levels of light (especially ultraviolet)
20) What is a photosynthetic quotient?
Answer: The photosynthetic quotient (PQ) is defined as the molar ratio of oxygen released to the carbon dioxide assimilated during photosynthesis.
PQ= Released O2/Received CO2
21) What is the common value of the PQ (photosynthetic quotient) of a leaf?
Answer: 1
22) What is the definition of photolysis?
Answer: Any chemical reaction in which a compound is decomposed after absorbing a photon.
Associated with a light phase of photosynthesis.
