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

Which pair of strains possess the genotype Tt?

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.

The branch of horticulture that deals with the study of fruits and their cultivation is known as

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

  1. Pomology

  2. Fruitology

  3. Pornography

  4. Economic botany

Show answer
Correct Option: A
Explanation:

Horticulture is the branch of agriculture that deals with growing plants used by people for food and medicine, as well as gardens and other forms of ornamental plants. This includes everything from fruits and vegetables to ornamental plants to spices. Anyone who works in any kind of garden is contributing to horticulture. One branch of horticulture is pomology, which is the branch that deals with fruit. The cultivation of any fruit crop falls under this branch, regardless of whether it is a single apple tree in someone's garden, or an entire orchard. Pomology includes everything from bananas to blueberries to strawberries and beyond.  Pomology deals with fruit plants throughout their life cycle, not just the fruit the plants produce. Horticulturalists in this branch cultivate fruit plants from seed all the way through fruit production.

So the correct option is 'pomology'.

Most advanced fruit is?

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

  1. Cypsela

  2. Caryopsis

  3. Pome

  4. Etaerio of drupe

Show answer
Correct Option: D
Explanation:
A.Cypsela - it is a dry indehiscent fruit, found in the family Asteraceae. It is the most advanced family in Dicotyledons.
B.Caryopsis - it is dry indehiscent fruit found in the family Poaceae.
C.Pome - It is fleshy fruit, in which false fruit is surrounded by true fruit, found in apple.
D.Etaerio of Drupes - A bunch of drupes formed from multicarpellary apocarpous gynoecium 
So, the correct option is 'Cypsela'.

Select the mismatched pair out of the following.

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

  1. Syconus - Ficus carica

  2. Sorosis - Ananas camosus

  3. Pome - Mangifera indica

  4. Cremocarp - Coriandrum sativum

Show answer
Correct Option: C
Explanation:

The mismatched pair is:

Pome - Mangifera indica,
 pome is a false fruit formed from the thalamus, as in apples, pears etc
The fruit of Mangifera indica (mango) is a drupe.
So, the correct answer is 'Pome - Mangifera indica'

Banana is 

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

  1. Cremocarp

  2. Parthenocarpic berry

  3. Drupe

  4. Capsule

Show answer
Correct Option: B
Explanation:

Banana is formed due to parthenogenesis. Banana is a seedless fruit which is formed without fertilization and pollination. Fruit formation without fertilization is called parthenogenesis . Hence banana is a parthenocarpic berry.

  2. Hard mesocarp

  3. Hard epicarp

  4. Hard epicarp and Hard mesocarp

Show answer
Correct Option: A
Explanation:

Drupe or a stone fruit is an indehiscent fruit. In this the exocarp (outer fleshy part) surrounds a pit of hard endocarp with a seed inside it. Due to this hard endocarp, drupes are called stony fruits.
