Multiple choice botany modes of reproduction different modes of reproduction sexual and asexual reproduction lifespan, reproduction and variation

The process of regeneration of new individual of the same kind is called as

  1. Metabolism

  2. Differentiation

  3. Reproduction

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Reproduction refers to the process by which new individual organisms (offspring) are produced from their parent.

Some animals like Planaria reproduce by regeneration. It is a type of asexual reproduction in which an organism is capable of regrowing certain body parts or the whole organism from different pieces.
So, the correct option is 'Reproduction'.

Multiple choice botany modes of reproduction different modes of reproduction sexual and asexual reproduction lifespan, reproduction and variation

The production of offsprings by sexual or asexual process is called as

  1. Division

  2. Growth

  3. Reproduction

  4. All of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Reproduction is the process by which organisms produce offspring that are similar to themselves.

  • Reproduction can be either sexual or asexual.
  • Asexual reproduction involves only a single organism while sexual reproduction involves gamete formation from two different sexes and their fusion.
  • So, the correct option is 'Reproduction'.

The process of production of closely resembled young one is called as

  1. Reproduction

  2. Division

  3. Growth

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • Cell Division results in two or more daughter cells.
  • Growth is the irreversible increase in the dry mass of an organism. It is brought about by an increase in cell size or number.
  • Reproduction results in production of closely resembling young ones.
  • So, the correct option is 'Reproduction'.

The process of propagation of new individual from the existing one is called as

  1. Fertilization

  2. Syngamy

  3. Reproduction

  4. Propagation
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • Reproduction refers to the production or propogation of new individuals by an organism. 
  • Syngamy of fertilisation refers to the fusion of gametes which may or may not be similar.
  • So, the correct option is 'Reproduction'.

  2. They are composed of one or more cells.

  3. They are capable of making their own food.

  4. They have organ systems to carry out the processes of life.
Reveal answer Fill a bubble to check yourself

How many of the following statements are wrong:
(i) Increase in mass and increase in number of individuals are twin characteristics of reproduction.
(ii) In unicellular organisms, reproduction is synonymous with growth.
(iii) Cellular organisation of the body is the defining feature of life forms.
(iv) Photoperiod affects reproduction in seasonal breeders only in plants.
(v) Living organisms are self regulating interactive systems.

  1. 1

  2. 2

  3. 3

  4. 4
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

(i) is wrong: Growth and reproduction are not twin characteristics. (ii) is correct: In unicellular organisms, growth and reproduction are synonymous. (iii) is correct: Cellular organization is a defining feature. (iv) is wrong: Photoperiod affects reproduction in both plants and animals. (v) is correct. Thus, two statements (i and iv) are wrong.

Multiple choice botany pollination and fertilization types of pollination cross pollination pollination and its types

The phenomenon of male and female structures maturing at two different 

times is ...............

  1. Dichogamy

  2. Heterostyly

  3. Hekrogamy

  4. Dioecious
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Dichogamy : It is defined as the condition in some flowering plants, in which the pistils and stamens mature at different times, thus preventing self-pollination. In other terms, it is defined as the maturation of male and female parts of a flower at different times, preventing automatic self-pollination.
