Compound leaves occur in
A. Mustard
B. Syzygium
C. Wheat
D. Sweet pea

Answer 1

Hint: It is possible to define a leaf as a thin and flat structure found in almost all plants. The leaves protrude from the stem of the plant; this exposes the leaves to the sunlight needed for the plants to grow their food. The type of leaf in which the blade has been split into the midrib can be identified as a compound leaf; this makes the leaf shape more than two separate leaflets.

Complete Answer:
- A leaf containing two or more leaflets originating from the same leafstalk can be defined as a compound leaf. These leaves have been divided into various classes according to their form and function, despite the fact that compound leaves have the same structure and characteristics.
- Two major groups were grouped into compound leaves: the pinnate compound leaves and the palmate compound leaves.
- The pinnate leaves are described as compound leaves in which the leaflets, as they are often called, are attached on both sides of the petiole or rachis.
- The pinnate leaf is made of a petiole linked to the twig. In accordance with the leaf arrangement on the rachis, the pinnate leaves are then further subdivided into various groups.
- For the even-pinnate leaf arrangement, the odd-pinnate leaflet arrangement, and the alternipinnada leaflet arrangement, there are three distinct types.
- The palmate compound leaves are a little easily identifiable because with their fingers extended out, they perfectly reflect a human hand.
- From a typical or single point of the petiole, the leaflets of these palmately compound leaves radiate. Since the arrangement of the leaflets resembles fingers on a palm, these leaves are known as palmate leaves.
- Some of the examples of compound leaves are Rose, Neem, Baobab, Desert cotton, Pea.

The correct answer is option(D) Sweet Pea.

Note: In photosynthesis, leaves are specifically used; this is the process in which plants produce their food in the presence of sunlight. They are often used in transpiration. There are different types of leaves, but they have been scientifically categorised into two, i.e. the simple leaves and the compound leaves, with different structures, size and shape.
