Multiple choice biology transport in plant transport in the phloem of plants vascular tissue permanent tissue

Which of the following is done during ringing experiment

  1. Bark is removed

  2. Pith is removed

  3. Xylem is removed

  4. All of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

In ringing experiment, the bark ring is scraped away which also removes the phloem causing xylem exposure. In this experiment, sugar moves downwards in the stem but the movement is stopped by the ring. As as result sugar bulge forms above the ring. This suggest that sugar transports down in the stem in the phloem.

So the answer is D.

Multiple choice biology transport in plant transport in the phloem of plants vascular tissue permanent tissue

Which one dies first when a ring of bark is removed?

  1. Shoot

  2. Root

  3. None

  4. Both shoot and root die simultaneously
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
The total removal of bark is called girdling, so when the bark is removed the roots will die first as they will starve without the sugar production by the leaves transported down.
So, the correct answer is 'Root'.

The loss of which will harm the tree most

  1. Bark

  2. Half the leaves

  3. Half the branches

  4. All the leaves
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
(A) The loss of bark called girdling will eventually lead to the death of the plant.
(B) Loss of half of the leaves will affect the rate of transpiration and the production of starch.
(C) Loss of half of the branches would not affect plant much.
(D) Loss of all of the leaves will either make the new leaf growth or if the plant is weak it will die.
So, the correct answer is 'Bark'.

In which season, sugar in the leaves will be readily consumed?

  1. Autumn

  2. Spring

  3. Winter

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Spring is considered as the flowering season. This is the period when there is growth of the floral buds which are formed at the apex of the vegetative shoots. Generally, there is a flow of sugar from the source (leaves) to sink end (roots). Due to the increase in the activity in the apex regions of the plant, there is consumption of food in the leaves. Hence, the food to the flower buds is supplied by the roots. 

Thus, the correct answer is option B.
