The following diagrams show the types of secondary thickenings in the xylem vessels. Identify the types labelled from A to F. Choose the correct option from those given.
Exp:D A lenticels is a porous tissue comprising cell with huge intercellular space these can be found in the root of dicotyledonous flowering plant the bark of woody stems. These small opening in the bark enable air to reach the remaining part of the root system.

Jute fibres are obtained from the
1 secondary phloem
2 pith
3 xylem
4 endodermis
Explanation:
Exp:A Jute fibres mainly compose of the cellulose and lignin. They are under the category of bast fibres which are collected from the skin of the plant or the secondary phloem.

Secondary cortex is also known as :
1 Phellem
2 Phelloderm
3 Phellogen
4 Bark
Explanation:
Exp:B Secondary cortex is also known as 'Phelloderm'. Phelloderm is a layer of parenchyma produced by the cork cambium, and inner secondary cortex of the cork cambium. It helps in the storage of food materials and ergastic substances.

In Cycas stem, open vascular bundle is characterized by
1 phloem being sand witched between xylem
2 cambium present in between xylem and phloem
3 xylem being sand witched between phloem
4 xylem and phloem occurring on different radii
Explanation:
Exp:B Secondary growth in stellar region \(\rightarrow\) It is due to activity of cambium. The cambium which is present between xylem and phloem called the intra fascicular cambium. The cambium between the vascular bundle called interfascicular cambium, inter fascicular cambium joined together to form complete cambium ring.
