The process that converts light energy into chemical energy in plants is:
A. Translocation
B. Respiration
C. Fermentation
D. Photosynthesis
Answer: Option D
Solution (By JKSSB Mock Tests)
Photosynthesis captures light energy via chlorophyll and converts CO₂ and H₂O into glucose and O₂. Respiration releases energy from glucose, fermentation is anaerobic, translocation is movement of solutes.
Explanation:
Anabaena azollae is a heterocystous cyanobacterium that lives symbiotically in the dorsal leaf cavities of the water fern Azolla. It fixes atmospheric nitrogen, providing a natural nitrogen source for rice paddies when Azolla is used as green manure. Nostoc is free-living or lichen symbiont, Rhizobium and Azotobacter are bacteria.
Explanation:
Mendel’s first law (segregation) states that the two alleles for a trait separate during gamete formation. Homozygous individuals have identical alleles; phenotype is observable trait; a monohybrid ratio is 3:1.
Explanation:
The retina is the light-sensitive inner layer of the eye containing photoreceptors (rods and cones) where an inverted real image is formed. The cornea and lens focus light onto the retina. The optic nerve transmits impulses from the retina to the brain for interpretation. The fovea centralis is the point of sharpest vision.
