Question

Laticiferous tissue is present in
 A . Hevea
 B .Cucurbita
 C .Utica
 D. nernen

Answer 1

Hint: It is a kind of prolonged secretory cell found in the leaves or potentially stems of plants that produce latex and elastic as auxiliary metabolites. These phones can reach up to several centimeters in length and can be fanned or unbranched.

Complete answer:
  Laticiferous tissue contains flimsy walled, extended and incredibly spread cells which are loaded up with smooth, yellowish hued juice known as latex. Latex shields the plant from herbivores. It is utilized economically to make elastic, stick, and so on. Cucurbita, Urtica, and Argemone don't show the presence of laticiferous conduits. Hevea is otherwise called elastic tree as elastic is industrially gathered from this tree. It shows the presence of laticiferous tissue.

Additional Information: Laticifers might be partitioned into: Verbalized laticifers, i.e., made out of a progression of cells consolidated, or Non-verbalized laticifers, comprising of one long coenocytic cell. Non-explained laticifers start their development from the meristematic tissue of the undeveloped organism, named the laticifer introductory, and can show persistent development all through the lifetime of the plant. Laticifer tubes have sporadically edged dividers and a bigger inward width than the encompassing parenchyma cells. In the improvement of the phone, prolongation happens by means of karyokinesis, and no phone plate comes about in coenocytic cells which stretch out all through the plant. They are thought to have a function in wound recuperating and as safeguard against herbivory, just as microorganism protection, and are frequently utilized for scientific classification.
So, the correct answer is ‘Hevea’.

Note: Laticifers were first depicted by H. A. de Barry in 1877. Laticifers are exceptionally particular cells which can deliver a wide assortment of proteins. These proteins incorporate catalysts working as proteinases and chitinases which help protect the creating plant against creepy crawlies and different herbivores. In one investigation it was discovered that the presence and grouping of certain proteins can contrast significantly inside the class Croton comparative with three species studied.
