Cell wall of xylem is rich in
1 Starch
2 lignin
3 lipid
4 protein
Explanation:
Exp:B Cell wall of xylem is rich in 'lignin'. Lignin and cellulose are found in the rigid cells. It helps in the transportation of water in stems. Presence of lignin is make up the wood of woody plants in Xylem cells.

Anatomically jute fibres are
1 Xylem fibres
2 Phloem fibres
3 Sclerenchyma fibres
4 Cortical fibres
Explanation:
Exp:B Anatomically jute fibres are 'Phloem fibres', are known as sclerenchymatous fibres, as they are made up of sclerenchyma cells. These fibres are mainly found in the phloem, so they are also called the 'phloem fibres'. It falls into the bast fibre category,

The sclerenchymatous part of pericycle which gives mechanical support is called:
1 hard bast
2 bast fibres
3 sclereids
4 wood fibres
Explanation:
Exp:B The sclerenchymatous part of pericycle which gives mechanical support is called 'bast fibres', bast fibres are called phloem fibres, they are sclerenchymatous dead cells that provide mechanical strength to the plants.

An old trunk of shisham (Dalbergia sisso) tree would possess maximum amount of
1 Primary xylem
2 Secondary xylem
3 Primary phloem
4 Secondary cortex
Explanation:
Exp:B Maximum amount of secondary xylem is present in an old trunk of shisham. It is formed from the secondary growth of the plants. Secondary growth increases the diameter of the stem in plants. In Dalbergia sissoo, a vascular cambium is found, its function is to produce wood cells and bark cells, vascular cambium produces a large amount of secondary xylem towards its inner side.
Exp:B Cell wall of xylem is rich in 'lignin'. Lignin and cellulose are found in the rigid cells. It helps in the transportation of water in stems. Presence of lignin is make up the wood of woody plants in Xylem cells.
