Question

transportation in plants? class 10 notes​

Answer 1

Answer:

Plants have tissues to transport water, nutrients and minerals. Xylem transports water and mineral salts from the roots up to other parts of the plant, while phloem transports sucrose and amino acids between the leaves and other parts of the plant.

Explanation:

Plants have two transport systems - xylem and phloem . Xylem transports water and minerals. Phloem transports sugars and amino acids dissolved in water.

Overall, water is transported in the plant through the combined efforts of individual cells and the conductive tissues of the vascular system. ... It is carried upward through the xylem by transpiration, and then passed into the leaves along another water potential gradient.

Answer 2

The transportation in plants is that the water and minerals are transported in plants by xylem and phloem of conducting tissues.

Explanation:

Xylem:

• Xylem is a long, non-living tube running from the roots to the leaves through the stem.

• The water is absorbed by the root hair and undergoes cell movement by osmosis until it reaches the xylem.

• This water is then transported through the xylem vessels to the leaves and is evaporated by the process of transpiration.

• The xylem is also composed of elongated cells like the phloem.

Phloem:

• The phloem is responsible for translocation of nutrients and sugar like carbohydrates, produced by the leaves to areas of the plant that are metabolically active.

• It is made up of living cells. The cells walls of these cells from small holes at the ends of the cells are known as sieve plates.
