Variation is the tendency of offspring to differ from its parents. Variation occurs due to change in genetic makeup of offsprings.
Q2. Glycolysis is also known as
Answer : Option A
Explaination / Solution:
The scheme of glycolysis was given by Gustav Embden, Otto Meyerhof, and J. Parnas, and is often referred to as the EMP pathway.

Answer : Option B
Explaination / Solution:

Q6. The differentiated cells have lost the capacity to divide can regain the capacity of division under certain conditions called as
Answer : Option B
Explaination / Solution:
The living differentiated cells that have lost the capacity to divide can regain the capacity of division under certain conditions. This phenomenon is termed as dedifferentiation.
Q7. The component that is essential to perform all physiological activities of the plant is
Answer : Option C
Explaination / Solution:

Q9. In Ulothrix or Spirogyra, reduction division (meiosis) occurs at the time of
Answer : Option A
Explaination / Solution:
In Ulothrix/Spirogyra reduction division (meiosis) occurs at the time of zygospore germination. Plant body of Ulothrix and Spirogyra, is gametophytic (haploid), they produce zoogametes (n) which fuses to form zygosporic (2n) diploid, which is a resting spore. Onset of favourable condition zygospore undergoes reductional division, or meiosis to produce zoo- meiospores.
Q10. Solarisation is
Answer : Option A
Explaination / Solution:
Solarisation is the inhibition of photosynthesis at very high light intensities due to photoxidation of certain compounds and destruction of chlorophyll moleucules.
