The stem of the plant when cut and dipped in the water helps in the transport of 

  1. Water

  2. Minerals

  3. Food

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

Stem contains special complex permanent tissues called xylem. The xylem helps in the conduction and transportation of water in one direction that is from stem to leaves. 

So the correct option is 'Water and minerals'.

  2. Runners

  3. Climbers

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

  1. Creeper is considered to be the plant that grows along the ground, by means of extending stem or branches and produce fiber-like roots that arise from the base of the stem and such weak stem are called prostrate stem.
  2. Runners are the stem that grows on the ground that forms adventitious roots and able to give rise to a new plant.
  3. Climbers are the plants that climb up other plant or object by the help of tendrils.
So the correct option is 'Creepers'

The stem was cut and dipped in water and red ink and colour of the leaves became red due to 

  1. The absorption of red ink by the leaves from the water

  2. The conduction of water and ink by the stem

  3. The loss of green colour from the leaves

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

This experiment is done to check the movement of water in stem in which ink is mixed with water and the stem is left in the mixture and after an hour we observe the stem and it shows that the ink is present inside the stem shows that the stem conducted the water and the ink, as well as the colored ink patches, are observing it proves that  the xylem and its elements help stem to conduct the water.

So the correct option is 'The conduction of water and ink by the stem'

Which is not a characteristic feature of the stem?

  1. Arises from plumule and is ascending

  2. Growing apex is having a bud

  3. Hairs are multicellular

  4. Branches arise endogenously
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Stems typically arise from the plumule, are ascending, have buds at their growing apices, and often feature multicellular hairs (trichomes). However, lateral branches on stems arise exogenously from outer cortical or epidermal tissues, not endogenously.
