Question

Which among the following gives us bast fibres and also shows bidirectional movement of the substances that ate transported through it?​

Answer 1

Answer:

Bast fiber, also called phloem fiber, is a type of plant fiber that can be collected from the phloem or bast surrounding the stem of certain dicotyledonous plants. Bast fibers can be obtained either from cultivated herbs, such as flax, hemp, and ramie, or wild plants, such as linden, wisteria, and mulberry .

Only phloem of a plant shows bidirectional movement because xylem only moves the water and minerals from root to the upper shoot. But phloem moves the nutrients from the leaf to other part of the plant and also move materials from xylem to the leaf. So it shows bidirectional movement.
