Test: The Flower, Fruit & Seed - NEET MCQ

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

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

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

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

In palmately reticulate venation there is more number of main veins arising from the base of the leaf. So it is otherwise called as multicostate type. Palmately reticulate or multicostate venation is again divided into two they are:

(i) Palmately reticulate (Divergent)

(ii) Pinnately reticulate (Convergent).
So the correct answer is C

Liliaceae is the characteristics representative of monocotyledonous plants. Floral characters of this family are: tricarpellary, actinomorphic, polyandrous, superior ovary, axile placentation.
So the correct answer is D

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

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

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

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
