Free Reproduction In Organisms (Weekly Quiz: 1) NEET Biology Questions & Answers with Detailed Explanation & Full Review

Free Reproduction In Organisms (Weekly Quiz: 1) Time:

Question-1

Identity the incorrect statement.

(a)

(b)

(c)

(d)

Explanation:

Answer: (a)

Asexual reproduction occurs usually in unicellular organisms by various ways like binary fission, budding, sporulation, etc. In this method, a single parent produces offspring with or without the involvement of gametes. Members of the kingdom fungi and simple plants reproduce through special asexual reproductive structures like conidia (Penicillium) buds (Hydra) etc. The most common of these structures are zoospores that are microscopic motile structures. All other options are correct.


Question-2

In which of the following pairs the plants can be vegetative propagated by leaf buds?

(a)

(b)

(c)

(d)

Explanation:

Answer: (b)

Leaves of a number of plants develop or possess adventitious buds for vegetative propagation e.g., Bryophyllum, Kalanchoe, Adiantum caudatum, etc.


Question-3

Offsprings of oviparous animals are at greater risk as compared to offsprings of viviparous animals because

(a)

(b)

(c)

(d)

Explanation:

Answer: (b)

Offspring's of oviparous animals are at greater risk as compared to offspring's of viviparous animals because proper embryonic care and protection is less in oviparous animals. Oviparous animals are those animals that lay eggs, with little or no other embryonic development within the mother. These eggs mature and hatch after being expelled from the body. Examples, most fish, amphibians, reptiles, all birds etc. Whereas viviparous animals give birth to young lives. The fertilized eggs develop into a young one inside the body of the female organisms. Therefore, chances of the survival of the young ones in viviparous animals is more because of proper embryonic care and protection inside the mother body


Question-4

Which of the following statement is correct in the process of fertilization ?

(a)

(b)

(c)

(d)

Explanation:

Answer: (a)

Fertilization is a process of the union of male and female gametes, during sexual reproduction, to form a zygote (or fertilized egg). Millions of sperms reach the egg but only one enters it. The entry of sperm activates the egg for completing the meiosis.


Question-5

Which of the following statements regarding the asexual reproduction is incorrect?

(a)

(b)

(c)

(d)

Explanation:

Answer: (b)

When offspring is produced by a single parent with or without the involvement of gamete formation, the reproduction is called asexual. As a result, the offspring that are produced are not only similar to one another but are also exact copies of their parent. Only mitotic division occurs in asexual reproduction.


Question-6

Life in all organism starts from

(a)

(b)

(c)

(d)


Question-7

Which of the following animals qualifies as a sexually reproducing, oviparous species ?

(a)

(b)

(c)

(d)

Explanation:

Answer: (a)

All these animals can reproduce sexually. However, only the chicken lays an external egg.


Question-8

Offsets are produced by

(a)

(b)

(c)

(d)

Explanation:

Answer: (a)

Offsets are produced by mitotic divisions. These are one internode long runners that occur in some aquatic plants. Breaking of offsets helps in vegetative propagation. These give rise to new plants, e.g. Eichhornia.


Question-9
