Question

The largest leaf belongs to
(А) Nerium
(B) Tobacco
(C) Victoria Musa
(D) Rafflesia

Answer 1

A leaf is usually a lateral structure that is flattened and born on stem . Leaf develops at the node and it has buds in its axil. Leaf takes its origin from the shoot apical meristem . It remains arranged in a corporeal manner on the stem. Leaves are the primary and most important organ that performs photosynthesis .

Complete answer:
A typical leaf consists of three parts:
Leaf base : The lowermost (basal) part of the leaf by which the leaf is attached to the node of the stem is called leaf base.
Petiole : The cylindrical stalk that joins the leaf base with the leaf blade (lamina) is called petiole.
Lamina or leaf blade: It is a green expanded part of the leaf. The leaf blade is supported by the veins and veinlets
The largest leaf are present in water lilies
Now let us see leaves of which plant are largest:-
Nerium: it is a shrub means it is a small tree so its leaves are also small. It belongs to the Apocyanaceae family. It is used as medicine to treat cancers.
Tobacco :- it has small leaves that are made to manufacture cigars. It belongs to the family solanaceae and genus nicotiana. Dried leaves of tobacco are used for smoking.
Victoria musa :- it has the largest leaves and belongs to family nymphaea. It belongs to water lilies . They are 3 metres in diameter and 8 metres in length.
Rafflesia :- this plant has no leaf at all. It does not have stem and roots also. It has only flowers and that too consists of only five petals.

Our required answer is C that is Victoria Musa.

Note: Different types of leaves can be seen in different plants. As a simple leaf is the leaf in which the leaf blade is not divided and it has bud at the axil of petiole. Compound leaves are leaves in which the leaf blade is completely broken . These are present usually in neem and tulsi.
