Fertilised egg is calledMarks:1
Explanation:Pollen produces male and female gamete which is formed in an ovule. During sexual reproduction, male gamete fuses with the female gamete or egg by the process of fertilisation. This fertilised egg which results after fusion of gametes is called zygote.
Seeds contain a/anMarks:1
Explanation:After fertilisation, the ovary grows into a fruit whereas ovule develops into a seed. This seed contains an embryo within it. The seed protects the embryo in a protective seed coat. This embryo, later on gives rise to a new plant.
A fully mature ovule containsMarks:1
7 cells and 8 nuclei
The fully mature ovule comprises 7 cells and 8 nuclei. Six of the eight nuclei are surrounded by cell walls and organised into cells; the remaining two nuclei, called polar nuclei are situated below the egg apparatus in the large central cell.
A seed is aMarks:1
After fertilisation, zygote divides several times to form an embryo within the ovule. The ovule develops a tough coat and is gradually converted into a seed. The ovary grows and ripens to form a fruit.
After fertilisation, the structure developing from the carpel isMarks:1
Pericarp is the wall of a ripened ovary, sometimes consisting of three distinct layers: endocarp, mesocarp and exocarp.
