Question

Define xylem
and
Phloem with
their part
and function​

Answer 1

Answer:

Here's Your Answer

Explanation:

Xylem transports and stores water and water-soluble nutrients in vascular plants. Phloem is responsible for transporting sugars, proteins, and other organic molecules in plants.

Xylem tissue is used mostly for transporting water from roots to stems and leaves but also transports other dissolved compounds. ... Phloem is responsible for transporting food produced from photosynthesis from leaves to non-photosynthesizing parts of a plant such as roots and stems.

Xylem is a vascular tissue that transports water and dissolved minerals absorbed from the roots to the rest of the plant. Phloem is a vascular tissue that transports soluble organic compounds prepared during photosynthesis from the green parts of the plant to the rest of the plant.

Answer 2

Explanation:

Xylem: This is the tissue that transports water and nutrients from root to upper parts of plant. It is composed of four types of cell i.e..,tracheid,vessel,xylem parenchyma and xylem fibres.

1. Traceids are long elongated cells with tapered ending.Tracheid cells are dead.It transports water through pits.
2. Vessel is a pipe like structure. vesseles are dead and have lignified thick cell wall .upper and lower portion of cell wall is absent.
3. Xylem Parenchyma are living cells.They store food and nutrients.
4. Xylem Fibres(sclerenchyma) are dead cells .They provide mechanical support to plant.

• Phloem: It is the tissue that transports food from site of photosynthesis to different parts of plants.

It is composed of five types :-

Sieve cells

Sieve tubes

companion cells

phloem fibres

Phloem parenchyma
