Answer: Option D. -> I and III
:
D
Asexual reproductionrequires only one parent plant.There is no exchanging of genetic information, therefore, offspring are clones of the parent. Asexual reproduction in plants can occur in a variety of forms which includesbudding, vegetative propagation, spore formation and fragmentation. Hence I and III are correct.

Answer: Option C. -> yeast
:
C
Buddingis a form of asexual reproduction in plants. Thenew plant develops from an outgrowth or bud due to cell division at one particular site. The offspring remains attached to the parent plant as it grows until it is mature.The offsprings areidentical tothe parent plant.Yeast reproduces with the help of this method.

Answer: Option D. -> I, III and IV
:
D
The pistil isthe female reproductive part of a flower. Itconsists ofthe stigma, style, and ovary. Anther isthe part of a stamen (male organ) that contains the pollen. Hence I, III and IV are components of a pistil.

Answer: Option A. -> True
:
A
Some plants like castor have fruits that burst with sudden jerks and scatter the seeds. Hence the statement is correct. This is, in fact, a form of seed dispersal in such plants.

Answer: Option D. -> I, III and IV
:
D
Spore formation is a type ofasexual reproduction. A sporeis areproductivebodyfound in bacteria, fungi, various plantsand some protozoans, that can developinto a new individual. Hence statementI, III and IV are correct.

Answer: Option C. -> Both asexual and sexual
:
C
Plant reproduction can beaccomplished by sexual orasexual ways. In sexualreproduction, offspring are formedby the fusion of gametes, which resultsin offspring, which are genetically different from theparents. In asexual reproduction, one parent is required to produce offspring and the offspring is identical to the parent. Vegetative reproduction is a mode of asexual reproduction.

Answer: Option C. -> take less time to grow and are identical to their parents
:
C
Plants produced by vegetative propagation are exact copies of their parent. This is a type of asexual reproduction. Such plants also take less time to grow, and mature, that is, they bear fruits faster than those produced by sexual reproduction.

Answer: Option B. -> ovule
:
B
Ovules is the partof flowerthat develops into seed after fertilization. Ovule is located inside the ovary and it consists of the female gamete. Eventually, the ovarydevelops into the fruit which contains the seeds.

Answer: Option A. ->
True
:
A
A flower can have both male and female reproductive parts. The male part is called androecium and the female part is called gynoecium. Such flowers are called bisexual flowers. E.g., hibiscus, lily etc.

A
:
A
Ovaries develop into fruits and ovules into seeds after fertilization. These fruits are responsible for dispersing the seeds that contain the embryo. They protect the seeds and help in the growth of a new plant.
