7. With respect to the cultivation of Tea, the withering process is used to __?
[A] To stop the tea leaf oxidation at a desired level
[B] To remove excess water from leaves and allows slight oxidation
[C] To alter the flavour of the tea
[D] To stop browning of tea
Show Answer
Correct Answer: B [To remove excess water from leaves and allows slight oxidation]
Notes:
Withering is used to remove excess water from the leaves and allows a very slight amount of oxidation. The process is also important in promoting the breakdown of leaf proteins into free amino acids and increase the availability of freed caffeine, both which change the taste of the tea.
8. Which of the following are longest cells of human body?
[A] Epethelial cells
[B] Pancreatic cells
[C] Nerve cells

10. Which of the following forms of Nitrogen is taken up by Higher Plants?
[A] Nitrites only
[B] Nitrates only
[C] Nitrates and ammonia
[D] Urea
Show Answer
Correct Answer: B [Nitrates only]
Notes:
Plants do not get their nitrogen directly from the air. Plants absorb nitrogen from the soil in the form of nitrate (NO3−) and ammonium (NH4+). Nitrate is the form of nitrogen most used by plants for growth and development. Nitrate is the form that can most easily be lost to groundwater.
Nitrogen is a component of chlorophyll and therefore essential for photosynthesis. It is also the basic element of plant and animal proteins, including the genetic material DNA and RNA, and is important in periods of rapid growth. Plants use nitrogen by absorbing either nitrate or ammonium ions through the roots.
