6 what are the dif blw the transport
as miniral in nylem
nylem and phreom.
Answers
Answer:
Xylem tissue helps in the transport of water and minerals. Phloem tissue helps in the transport of food. ... Transport in xylem requires physical forces such as transpiration pull. Transport of food in phloem requires energy in the form of ATP.
I think this answer would help you. Please mark me as brilliant if you think this answer is correct according to you and follow me friends ☺️
Answer:
i think your question is xylem and phloem
Explanation:
Xylem transports water and soluble mineral nutrients from roots to various parts of the plant. It is responsible for replacing water lost through transpiration and photosynthesis. Phloem translocates sugars made by photosynthetic areas of plants to storage organs like roots, tubers or bulbs.
Xylem and Phloem are two different types of vascular tissues, which are mainly involved in the transportation process. These tissues form a vascular bundle and these work together as a unit. The movement of xylem is unidirectional, while the movement of phloem is bidirectional.
Xylem Phloem
Definition
Xylem tissues are the tubular-shaped structure, with the absence of cross walls. This tissue resembles the shape of a star. Phloem tissues are tubular-shaped, elongated, structures with the presence of walls with thin sieve tubes.
Location
xylem is located in the centre of the vascular bundle. phloem is located on the outer side of the vascular bundle.
Fibres
Xylem fibres are smaller. Phloem fibres are larger.
Found In
They are present in roots, stems and leaves. They are present in stems and leaves, which later transports and grow in roots, fruits and seeds.
Movements
These tissues move in a Unidirectional. (only in one direction – upward direction) These tissues move in a Bidirectional. (both ways – up and down)
Comprises
They live with hollow dead cells. They live with cytoplasm without the nucleus.
No of Tissues
The total amount of xylem tissue is more. The total amount of phloem tissue is less.
Features
It consists of tracheids, vessel elements, xylem parenchyma, xylem sclerenchyma and xylem fibres. It consists of four elements: companion cells, sieve tubes, bast fibres, phloem fibres, intermediary cells and the phloem parenchyma.
Functions
Transports soluble mineral nutrients and water molecules from the roots to the aerial parts of the plant. Transports food and other nutrients including sugar and amino acids from leaves to storage organs and growing parts of the plant.
Vascular Bundles
Forms vascular bundles with phloem. Forms vascular bundles with xylem.
Functions
Provides mechanical strength to the plant and helps in strengthening the stem. Translocates the synthesized sugars by the photosynthetic areas of plants to storage organs like roots, bulbs and tubers.
Functions
It is responsible for replacing the total amount of lost water molecules through transpiration and photosynthesis. It is responsible for transporting proteins and mRNAs throughout the plant.
