Question

Placenta and Pericarp are both edible in
(a)Banana
(b)Tomato
(c)Potato
(d)Apple

Answer 1

Hint: The characteristic feature of angiosperm is the presence of fruit. The ripened or mature ovary is called fruit. The placenta is a cushion-like structure in the ovary. Pericarp develops from the wall of the ovary.

Complete answer:
The fruit is the characteristic feature of an angiosperm. Parts of fruits are: Fruit wall (pericarp), Seeds develop from the ovules. The fruit wall or pericarp develops from the wall of the ovary. It can be dry or fleshy. If the pericarp is thick and fleshy then it differentiates into three different layers namely:
-Epicarp (outer cover)
-Mesocarp (middle layer)
-Endocarp (innermost layer)
Seeds develop from ovules in some plant’s ovary grows into fruits without fertilization such fruits are known as parthenocarpic fruits. They are seedless fruits. For example, Bananas and grapes.
The fruit which develops from the ovaries is called true fruit. If any floral part takes part in their formation, they are known as false fruits (pseudocarp) For example, apple, and pear.
Tomato is a berry in which both pericarp and placenta are edible.
A berry is a fleshy fruit. Has one-two many-seeded fruits. Epicarp forms the outer screen. The middle thick and fleshy part is called mesocarp with a membrane-like endocarp. Examples: Tomato, Guava, Papaya.
In tomato, the arrangement of the placenta is axillary (axile). In axile placentation, the placenta is present in the axile position and the ovule is attached to it in the multilocular ovary. Example, tomato, and lemon.
So, the correct answer is, “Tomato.”

Note: The fruit wall is also known as pericarp and the ovary can have one or more placenta. Based on the number of placenta and the number of valves thus formed, the ovaries and hence the fruits can be classified as unilocular, bilocular, or multilocular. Each locule may have one or many seeds.
Betelnut is a one-seeded berry.
