Practice questions testing deep understanding of double fertilization in angiosperms.
Q1. Describe the specific events that occur immediately after a compatible pollen grain lands on the stigma of a flower, leading up to the penetration of the ovule.
Q2. Angiosperms (flowering plants) undergo a unique process known as "Double Fertilization." Explain the two specific fertilization events that make up this process inside the embryo sac.
Q3. Assertion (A): After fertilization, the ovary of the flower transforms into a seed. Reason (R): The ovary wall hardens to become the tough outer seed coat to protect the embryo.
