Reason: In Protists and Monerans, the organism or the parent cell divides into two to give rise to new individuals.

A

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

The correct Answer is:
A

In Protists and Monerans, the organism or the parent cell divides into two to give rise to new individuals. Thus in these organisms cell-division is itself a mode of reproduction.

Read the following statements and find out the incorrect statements. a. Asexual reproduction is common among single celled organisms, and in plants and animals with relatively complex organisations. b. In yeast, the division is unequal and small buds are produced that remain attached initially to the parent cell which eventually gets separated and mature into new yeast organism (cells). c. Vegetative reproduction is also a type of asexual reproduction. d. While in animals and other simple organisms the term vegetative reproduction is used unambiguously, in plants, the term asexual reproduction is frequently used. e. Water hyacinth is also called 'Terror of Bengal.'

In yeast and Amoeba the parent cell divides to give rise to two individual cells. How does the cell division differ in these two organisms?

Assertion: During embryogenesis, cell division increase the number of cells in the developing embryo. Reason: During embryogenesis, cell differentiation helps groups of cells to undergo certain modification to form specialised tissues and organs to form an organism.

Assertion: In haploid organism, specialised cells called meiocytes (gamete mother cells) undergo reduction division. Reason: Chromosome number in the meiocyte is half the number of chromosome in gamete.

Assertion: Each cell of sporogenous tissue is a potential pollen mother cell (PMC) or microspore mother cell. Reason: Each cell of the sporogenous tissue is capable of giving rise to a microspore tetrad

Read the following statements carefully and select the appropriate option given below. (i) Reproduction is defined as a biological process in which an organism gives rise to the young ones (offspring) similar to itself. (ii) Adventitious buds arise from the notches present at margins of leaves of Bryophyllum. (iii) Asexual reproduction is common among single celled organisms, and in plants and animals with relatively simple organisations. (iv) A few plants exhibit unusual flowering phenomenon, some of them such as bamboo species flower only once in their life time, generally after 50-100 years. (v) The events of asexual reproduction though elaborate and complex, follow a regular sequence.
