give three differences between xylem and phloem
Answers
Answer:
Xylem tissues are found in leaves, roots, and stems. Phloem tissues are found in stems and leaves which later grow in the roots, fruits, and seeds. Xylem tissue is composed of xylem vessels, fibers, and tracheids. Phloem tissue is composed of like sieve tubes, companion cells, phloem fibers, and phloem parenchyma.
Answer:
Important difference between xylem and phloem
Parameter Xylem Phloem
Meaning Complex tissue of plants that transports water and nutrients within the plant Living tissue that transports food and organic materials within the plant
Type of Cell Contains dead cells with the exception of parenchyma Contains of mostly living cells
Materials It comprises of fibre, tracheids, and xylem vessels It comprises of sieve cells, sieve tubes, phloem fibres, phloem parenchyma, and companion cells
Location The location of xylem is deep in the plant, in the centre of vascular bundle The location of phloem is on the outer side of the plant’s vascular bundle
Mechanical Support It provides mechanical support Provides no mechanical support
Type of Movement Undirectional Bidirectional
Xylem and Phloem functioning Transports only waters and minerals from roots Transports food materials whose preparation takes place by the green parts of the plant
Proportion of Plant Xylem constitutes mostly the bulk of the body of the plant Phloem constitutes a small part of the body of the plant
Conducting Cells In xylem, the conducting cells are dead In phloem, the conducting cells are certainly living
