Plant Reproduction and Germination Questions
-
storage
-
vegetative reproduction
-
sexual reproduction
-
none of these
B
Correct answer
Explanation
The eyes of a potato are axillary buds located on the tuber. These buds can sprout to form new plants, serving as a primary method of vegetative reproduction.
B
Correct answer
Explanation
Non-endospermic (exalbuminous) seeds are those where the endosperm is consumed during development, as seen in most dicots like peas and beans. Maize, wheat, and rice are monocots with endospermic seeds.
-
aleurone layer
-
epidermis
-
scutellum
-
epithelium
A
Correct answer
Explanation
Aleurone is a protein found in protein granules of maturing seeds and tubers. The term also describes one of the two major cell types of the endosperm, the aleurone layer. The aleurone layer is the outermost layer of the endosperm, followed by the inner starchy endosperm.
C
Correct answer
Explanation
The flower is the reproductive part of the plant where seeds are produced. Stems, leaves, and roots have other functions like support, photosynthesis, and nutrient absorption.

All of these
-
Only a and b
D
Correct answer
Explanation
This is the correct answer. The outer hard cover of a seed is called seed coat. Beneath the seed coat, there are the seed leaves called cotyledones. The food required to keep the embryo alive is in the cotyledon. The seed carries an embryo inside. It carries the basic parts, which are the plumule and the radicle.

D
Correct answer
Explanation
This is the correct answer. Coconut seed is dispersed through water. It has a thick fibrous covering around its seeds that help them to float. Hydrilla is a water plant and it uses water to disperse its seeds.

-
Pinus
-
Funaria
C
Correct answer
Explanation
Gymnosperms bear naked seeds. So, option (3) is correct.
