Placenta and pericarp are both edible portions in
A. Apple
B. Banana
C. Tomato
D. Potato
Solution
Hint:- A true fruit consists of two main parts- the seeds that develop from ovules and the pericarp or the fruit wall which develops from the wall of the ovary. The structure and thickness of pericarp varies greatly in different kinds of fruits.
Complete Answer:- Apple is an example of false fruit. False fruits are derived from the ovary along with other accessory floral parts. In apples the main edible part of the fruit is a fleshy receptacle.
Banana is an example of parthenocarpic fruit. Parthenocarpic fruit are fruits formed without fertilization of ovules so they do not form seeds.
Potatoes are an example of stem tubers. The stem tubers are the swollen ends of specialized underground stem branches that arise as suckers or stolons. These tubers have spirally arranged depressions called eyes which represent nodes.
Tomato is an example of berry fruit. Berry is a type of fleshy fruit which means it consists of a fleshy pericarp. It is usually many seeded fruits with massive, pulpy and juicy pericarp produced from a syncarpous ovary. The pericarp of fruit basically consists of three layers- epicarp i.e. the outer covering, mesocarp or the middle covering and the endocarp i.e. inner covering.
The epicarp of berries generally becomes conspicuously colored when ripe, for example, banana, brinjal, guava, supari, papaya, etc.
The placenta can be defined as an outgrowth of a parenchymatous tissue in the inner wall of the ovary to which the ovule or ovules remain attached.
Thus, both placenta and pericarp in tomatoes are edible.
So the correct answer is C. Tomato.
Note:- The placenta usually develop on the margins of the carpels, either along their whole line of union called the suture or at their base or apex. The arrangement of the placentae in the cavity of the ovary is known as placentation.
