The part of the fruit that develops from the ovary wall is called__________.

A.
Pericarp
B.
Seed coat
C.
Endosperm
D.
Cotyledon

Detailed Solution: Question 1

The pericarp is the part of the fruit that develops from the ovary wall. After fertilization, the ovary undergoes changes and develops into a mature fruit. The pericarp consists of three layers: the exocarp, mesocarp, and endocarp.
So the correct answer is A

Topic in NCERT: THE FRUIT

Line in NCERT: "Generally, the fruit consists of a wall or pericarp and seeds."

A.
Margins of sepals or petals overlap one another but not in any particular direction.
B.
Margins of sepals or petals overlap one another in a particular direction.
C.
Margins of sepals overlap the petals in a definite pattern.
D.
Margins of sepals or petals do not overlap in any pattern.

If the margins of sepals or petals overlap one another but not in any particular direction as in Cassia and gulmohur, the aestivation is called imbricate.

Topic in NCERT: Aestivation

Line in NCERT: "If the margins of sepals or petals overlap one another but not in any particular direction as in Cassia and gulmohur, the aestivation is called imbricate."

Test: The Flower, Fruit & Seed - Question 5

D.
Actinomorphic flower

Detailed Solution: Question 5

A mustard flower is an example of an actinomorphic flower.
A flower is said to be actinomorphic if it possesses radial symmetry and zygomorphic if it possesses bilateral symmetry.

Topic in NCERT: Flower: bisexual, actinomorphic

Line in NCERT: "When a flower can be divided into two equal radial halves in any radial plane passing through the centre, it is said to be actinomorphic, e.g., mustard, datura, chilli."

Which among the following is incorrect about racemose and cymose?

A.
In cymose inflorescence, the floral main axis continues to grow throughout the life
B.
In racemose inflorescence, the youngest flower remains at the top of floral axis
C.
In racemose inflorescence, indefinite number of flowers are formed
D.
In cymose inflorescence, the axilary branches continue to grow throughout the life

Detailed Solution: Question 6

In racemose inflorescence, the youngest flower remains at the top of floral axis and indefinite number of flowers are formed.
In cymose inflorescence, the floral main axis is limited however the axilary branches continue to grow throughout the life.

Topic in NCERT: THE INFLORESCENCE

Line in NCERT: "In cymose type of inflorescence the main axis terminates in a flower, hence is limited in growth."

Test: The Flower, Fruit & Seed - Question 7

A scar on the seed coat through which the developing seeds attached to the fruit is called as ________.

A.
testa
B.
tegmen
C.
hilum
D.
micropyle

Detailed Solution: Question 7

The outer layer is called testa and the inner layer is called tegmen. There is a scar on the seed coat through which the developing seed was attached to the fruit. This scar is called hilum.
So the correct answer is C

Topic in NCERT: Structure of a Dicotyledonous Seed

Line in NCERT: "The hilum is a scar on the seed coat through which the developing seeds were attached to the fruit."

Test: The Flower, Fruit & Seed - Question 8

A Flower which can be divided into equal vertical halves by more than one plane of division is__________.

A.
Cyclic
B.
Zygomorphic
C.
Actinomorphic
D.
Heteromorphic

Detailed Solution: Question 8

Actinomorphic flowers are radially symmetrical, they are able to be divided into similar halves in more than one vertical plane.
Zygomorphic flowers are bilaterally symmetrical,they can be divided into similar halves in only one plane.
Cyclic is a type of floral organ arrangement, the floral organs are arranged in regular whorls at the node of the thalamus.
Heteromorphic is a type of incompatibilty, same species produce more than one morphological type of flower.
So the correct answer is C

Topic in NCERT: Flower: bisexual, actinomorphic

Line in NCERT: "When a flower can be divided into two equal radial halves in any radial plane passing through the centre, it is said to be actinomorphic, e.g., mustard, datura, chilli."

Test: The Flower, Fruit & Seed - Question 9

Flowers in which only one set of essential organs is present are said to be__________.

A.
Polygamous
B.
Bisexual
C.
Dioecious
D.
Unisexual

Detailed Solution: Question 9

POLYGAMY ⇒ The condition of bearing some flowers with stamens only, some with pistils only, and some with both, on the same or different plants.

BISEXUAL ⇒ The flower having both male and female reproductive organ on the same plant.

DIOECIOUS ⇒ Both male and female plants may have flowers, but one will have "male" flowers and the other "female" flowers.

UNISEXTUAL ⇒ The flower which has only one essential worl either male or female.
So the answer is D

Topic in NCERT: THE FLOWER

Line in NCERT: "A flower having either only stamens or only carpels is unisexual."

Test: The Flower, Fruit & Seed - Question 10

A.
They have a single cotyledon.
B.
The endosperm is well-developed and absorbs the cotyledons.
C.
The seed possesses two embryonic leaves or cotyledons
D.

Detailed Solution: Question 10

Dicotyledon is a classification of flowering plants where the seed possesses two embryonic leaves or cotyledons.

Topic in NCERT: Structure of Dicotyledonous Seed

Line in NCERT: "Within the seed coat is the embryo, consisting of an embryonal axis and two cotyledons."

The structure that develops into the seed after fertilization is the__________.

A.
Ovary
B.
Anther
C.
Ovule
D.
Stigma

Detailed Solution: Question 11

Once fertilization occurs, the ovule undergoes various changes and develops into a seed. The fertilized ovule contains an embryo, which is the future plant, and it is surrounded by protective layers such as the seed coat. The ovule provides nourishment to the developing embryo until it matures into a seed.
So the correct answer is C

Topic in NCERT: THE SEED

Line in NCERT: "The ovules after fertilisation, develop into seeds."

Test: The Flower, Fruit & Seed - Question 12

A.
Cotyledons
B.
Endosperm
C.
Seed coat
D.
Embryo axis

Detailed Solution: Question 12

In Monocots, during seed development, the endosperm is formed. The endosperm is a tissue that surrounds the embryo and serves as a nutrient reserve. It contains stored carbohydrates, proteins, oils, and other nutrients necessary for the growth and development of the embryo after germination.
So the correct answer is B

Topic in NCERT: Endosperm

Line in NCERT: "The endosperm is bulky and stores food."

Test: The Flower, Fruit & Seed - Question 13

Detailed Solution: Question 13

The pistil, also known as the carpel, is the female reproductive organ of a flower. It is located in the center of the flower and consists of several parts. The main parts of the pistil include the stigma, style, and ovary.
So the correct answer is B

Topic in NCERT: Gynoecium

Line in NCERT: "Gynoecium is the female reproductive part of the flower and is made up of one or more carpels."
