What is the role of the ovary in the process of fertilisation in plants?
To produce the egg cell
To produce pollen
To store the male gametes
To provide nutrients to the pollen grains
To produce the egg cell
In angiosperms (flowering plants), the ovary is the basal, swollen part of the pistil (gynoecium). It serves as the container for the ovule, which holds the egg cell (female gamete), and after fertilisation, it matures into the fruit while the ovule becomes the seed.
In angiosperms (flowering plants), the ovary is the basal, swollen part of the pistil (gynoecium). It serves as the container for the ovule, which holds the egg cell (female gamete), and after fertilisation, it matures into the fruit while the ovule becomes the seed.
Think of the ovary as a 'protective nursery'; it provides the secure environment and the essential 'egg' (seed starter) necessary to grow the next generation of plants.
Zygote=n(egg)+n(male┬аgamete)=2n
During double fertilisation, a pollen tube delivers male gametes to the embryo sac within the ovule inside the ovary. One male gamete fuses with the egg cell to form a diploid zygote (2n), initiating the development of the future plant embryo. The ovary wall eventually thickens to protect these developing seeds, forming the pericarp of the fruit.
The ovary acts as the female reproductive organ.
Double fertilisation occurs specifically in angiosperms.
The zygote undergoes mitosis to form the embryo.
Ovary matures into the fruit; ovule matures into the seed.
Protects developing seeds from environmental stress.
Facilitates seed dispersal through fruit structure.
Agriculture (crop yield determination).
Botanical classification of fruits.
Option B (To produce pollen) is incorrect because pollen is produced by the anther (part of the stamen).
Option C (To store male gametes) is incorrect as the pollen grain itself carries male gametes.
Option D is incorrect because nutrients for pollen are provided by the tapetum inside the anther.
A is correct тАФ The ovary is the specific reproductive structure that houses the ovule containing the egg cell, which is essential for fertilisation.
Remember: Stamen (Male) produces Pollen; Pistil/Carpel (Female) contains the Ovary which produces the Egg. Think 'M' for Male-Microsporangium and 'F' for Female-Flower-Fruit.
