It will not be any advantage to produce seedless fruits in

biology fruit and seed morphology of the fruit fruit plants: structure and function

  1. Mangoes

  2. Watermelons

  3. Pomegranate

  4. Oranges

Show answer
Correct Option: C
Explanation:

Pomegranate is fruit which has leathery-skinned berry within which it contains many seeds. Each seed is surrounded by a juicy and fleshy aril. It contains hundred of edible seeds. So, it will not be any advantage to produce seedless fruit in pomegranate.

So, the correct answer C 'Pomegranate'

An aggregate fruit is the one which develops from

  1. Multicarpellary apocarpous gynoecium

  2. Complete inflorescence

  3. Multicarpellary superior ovary

  4. Multicarpellary syncarpous gynoecium

Show answer
Correct Option: A
Explanation:

The aggregate fruits are formed from polycarpellary, apocarpous ovary and each ripened is called fruitlet or etaerio. The example is raspberry.

So the correct option is 'Multicarpellary apocarpous gynoecium'.

A number of fruitlets(seeds) of Strawberry are removed randomly during development of fruit.

Correct Option: B

Which of the following represents the edible part of the fruit of Litchi -

biology fruit and seed morphology of the fruit fruit plants: structure and function

  1. Endocarp

  2. Pericarp

  3. Juicy aril

  4. Mesocarp

Show answer
Correct Option: C
Explanation:

In Litchi, Aril is the edible part of the fruit. It is a collar like an outgrowth from the ovule base. 

So the correct option is C.

An aggregate fruit develops from an inflorescence.

biology fruit and seed morphology of the fruit fruit plants: structure and function

  1. True

  2. False

Show answer
Correct Option: B
Explanation:

A fruit is a seed-bearing structure in flowering plants (also known as angiosperms) formed from the ovary after flowering. An aggregate fruit results from the joining together of several ovaries of the same flower. This process starts with a flower that contains several carpels with an equal number of ovaries. As the ovaries develop and increase in size they become attached together. Aggregate fruits are also either true, without accessory parts, or accessory, with additional floral parts. 

So the given statement is false.

Pineapple $\left (ananas  \right )$ fruit develops from-

biology fruit and seed morphology of the fruit fruit plants: structure and function

  1. a unilocular polycarpellary flower

  2. a multipistillate syncarpous flower

  3. a cluster of compactly borne flowers on a common axis

  4. a multilocular monocarpellary flower

Show answer
Correct Option: C
Explanation:
The fruit of Ananas comosus (pineapple or ananas) is sorosis, (a type of multiple fruits), developing from spike, spadix or catkin. In this type, the flowers associate by their succulent tepals, the axis bearing them grows and becomes fleshy or woody, thus, the whole inflorescence turns into a compact fruit.

So, the correct answer is 'a cluster of compactly borne flowers on a common axis'.

Juicy hair-like structures observed in the lemon fruit develop from : -

biology fruit and seed morphology of the fruit fruit plants: structure and function

  1. Exocarp

  2. Mesocarp

  3. Endocarp

  4. Mesocarp and endocarp

Show answer
Correct Option: C
Explanation:

Endocarp in citrus is divided into segments, containing juicy hair like vesicles filled with the juice of the fruit.The epicarp or Flavedo is the outer most covering also called the rind, it contains oil glands. The mesocarp is fused with the epicarp, and is fibrous in nature it also forms the central column of the fruit and is also the called the pith/albedo.   

So, the correct answer is 'Endocarp.'

Fruit shape in shephered's purse(Capsella bursa) is of two types-triangular and top-shaped. Triangular fruit shape(T) is dominant over top-shape (t). Following table summarises the results of several crosses.

Cross Result
Strain 1 x tt All triangular
Strain 2 x tt 1 triangular : 1 top-shaped
Strain 3 x tt All top-shaped
Strain 4 x tt 3 triangular: 1 top-shaped

Nut fruit has

biology fruit and seed morphology of the fruit fruit plants: structure and function

  1. Hard pericarp

  2. Soft pericarp

  3. No pericarp

  4. Pericarp fused with thalamus

Show answer
Correct Option: A
Explanation:

The pericarp is a tissue that develops around the seeds. These are made up of three layers the epicarp, mesocarp and endocarp. In nuts, the pericarp is a hard indehiscent layer surrounding the seed. Nuts usually have stony pericarp which is hard in nature.
