Questions Related to transport in the phloem of plants

Choose the correct answers from the alternatives given.
Which of the following tissues transports water and nutrients within the plant?

  1. Epidermal tissue

  2. Ground tissue

  3. Meristem

  4. Vascular tissue


Correct Option: D
Explanation:

Xylem is the chief water and nutrients conducting tissues of the plants. These xylem tissues form the part of vascular tissues. These conduct water and nutrients from the roots to the top of the plants i.e. to the stem and the leaves. Along with acting as a conducting tissue, xylem also provides the mechanical strength to the plant parts.

Hence, the correct answer is 'Vascular tissue'.

The phenomenon of osmosis is involved in the diffusion of water from

  1. One cell to another

  2. Soil to root

  3. Xylem vessel  to xylem vessel

  4. None of the above


Correct Option: C
Explanation:

Osmosis is the process of flow of fluid from higher to lower concentration through the semi-permeable membrane. The wall of xylem vessels behaves as the semi-permeable membrane so diffusion of water from one xylem vessel to another xylem vessel can be called the phenomenon of osmosis.

In all other three cases, there is no presence of semi-permeable membrane so, it is the simple diffusion process.
So, the correct answer is the 'xylem vessel to xylem vessel'.

........ conducts water and ions whereas ........ conducts food.

  1. Phloem; xylem

  2. Xylem; phloem

  3. Cambium; phloem

  4. Xylem; cambium


Correct Option: B
Explanation:
Vascular tissues help in transportation such as xylem and phloem. The xylem carries water and dissolved ions from the root to stem and leaves and phloem carry dissolved sugar from the leaves to all other parts of the plants. So, the correct answer is "xylem; phloem.
