Morphology of Flowering Plants MCQ for NEET

Morphology of flowering plants is the study of the form and structure of plants.The morphology of flowering plants reveals a fascinating display of structures and adaptations that enable them to survive, reproduce and thrive in diverse environments. Understanding these fundamental aspects can deepen our appreciation for plant diversity and complexity.

The book starts by examining the external features of a flower, including sepals, petals, stamens and pistils, highlighting their functions and variations across species. It then explores how flowers are designed for pollination, whether by insects or wind, through adaptations like bright colours and fragrant scents.

Additionally, the book provides detailed insights into leaf morphology, emphasizing its essential role in photosynthesis. It explores into stem anatomy, which is important for transporting water and nutrients throughout the plant system.

Answer. B

Q3. Which plant amongst following bears fibrous root system ?

A) Mustard plant

B) Wheat plant

C) Monstera

D) Banyan tree

Answer. B

Explanation: (b) Fibrous roots are large number of roots that originates from the base of stem after replacing the short-lived primary root. These can be seen in monocotyledonous plants like wheat plant.

Q4. In monocotyledonous plants, the primary root is short-lived and is replaced by a large number of roots. These roots originate from the base of the stem and constitute the

A) prop roots

B) pneumatophores

C) napiform

D) fibrous roots

Answer. D

Q5. Which of the following is the smallest region of the root ?

A) Root cap

B) Region of elongation

C) Region of meristematic activity

D) Region of maturation

Answer. C

Explanation: (c) Smallest region of root is meristematic or growing point as the cells in this region are very small, actively dividing and having a dense cytoplasm.

Q6. Root hairs develop from the region of

NEET 2017

A) maturation

B) elongation

C) root cap

D) meristematic activity

Answer. A

Q7. Select the group of plants that possess stilt roots.

A) Zea mays, Saccharum officinarum

B) Pandanus odoratissimus, Ficus benghalensis

C) Rhizophora mangle, Hedera helix

D) Ficus benghalensis, Pisum sativum

Answer. A

Explanation: (a) Stilt roots are the supporting roots coming out of the lower nodes of the stem. They can be seen in Zea mays (maize), Saccharum officinarum (sugarcane), etc.

Q8. Identify the mismatched pair.

A) Prop roots - Provide support

B) Stilt roots - Originate from stem's nodal part

C) Pneumatophores - Help in storing food

D) Edible roots - Sweet potato

Answer. C

Explanation: (c) Option (c) contains the mismatched pair that can be corrected as
In some plants such as Rhizophora (growing in swampy areas), many roots came out of the ground and grow vertically upwards. Such roots are called pneumatophores, which help to get oxygen for respiration, i.e. respiratory roots.

Q9. The stem is the \( \ldots\) A \( \ldots\) part of the axis, which bears branches, leaves, flowers and fruits. It develops from the \(\ldots \) B \(\ldots \) part of the embryo of a germinating seed.
Appropriate options for A and B is

A) A - descending; B - radicle

B) A - radicle; B - descending

C) A - ascending; B - plumule

D) A - plumule; B - ascending

Answer. C

Q10. Nodes are the region of stem where

A) food is stored by plants

B) leaves are borne

C) xylem and phloem are present

D) axillary buds develop

Answer. B

Explanation: (b) The region of the stem where leaves are borne are called nodes, while internodes are the portions, between two nodes. Axillary buds develop in the axil of leaf.
