Carbohydrates are commonly found as starch in plant storage organs. Which of the following five properties of starch (a - e) make it useful as a storage material?
(a) Easily translocated
(b) Chemically non-reactive
(c) Easily digested by animals
(d) Osmotically inactive
(e) Synthesized during photosynthesis
The useful properties are:
(a) and (e)
(b) and (c)
(b) and (d)
(a), (c) and (e)
|Column I||Column II|
|A||Warburg effect||p||Change in gene frequency by chance|
|B||Pasteur effect||q||Postponing severance in the leaves by applying cytokinin|
|C||Emerson effect||r||Decline in the consumption of respiratory substrate due to a change from anaerobic to aerobic respiration|
|D||Wright effect||s||Inhibitory effect of O2 on photosynthesis|
|t||Enhancement of photosynthesis by subjecting chlorophyll to the effect two different wavelengths of light|
A = s, B = t, C = q, D = r
A = s, B = r, C = t, D = p
A = t, B =s, C = p, D = q
A= t, B = r, C = p, D = s
Assertion: Rhoeo leaves contain anthocyanin pigments in epidermal cells.
Reason: Anthocyanins are accessory photosynthetic pigments.
Both Assertion and Reason are true and the Reason is the correct explanation of the Assertion
Assertion and Reason are true but the Reason is not the correct explanation of the Assertion
Assertion is true statement but Reason is false
Assertion and Reason are false statements
Only ATP is formed NADPH+ + H+ is not formed
There is no evolution of O2
There is unidirectional cyclic movement of the electrons
Photosystem I stops getting excited at a wavelength of light beyond 680 nm
