draw a diagram and explain reproduction in flowering plants
Answers
Answer:
Explanation:
i. The flower is the reproductive organ in sexually reproducing plants.
ii. Stamen is the male organ and carpel is the female organ of the flower.
iii. Flowers having both stamens and carpels are called bisexual flowers.
iv. Stamens produce male gametes called pollen grains, and carpels produce female gametes called ovules or egg cells inside ovaries.
v. Fertilization of the egg cell by the pollen grain takes place in the ovules.
vi. The fertilized egg cell later develops into an embryo and the entire ovule gets converted into a seed.
vii. The seed germinates under favorable conditions to give rise to a new plant.
Answer:
The pollen grains germinate on the stigma after pollination. The inner wall of the pollen grain grows into a pollen tube, which grows down through the style and finally reaches the ovule. Inside the ovule, a male gamete fuses with the female gamete and a zygote is formed. This is known as fertilization.
