Mention the site of zygote formation in the ovule of a flowering plant. What happens to sepals, petals and stamens after fertilisation? State the fate of zygote, ovule and ovary in these plants.
Name the structure through which pollen tubes enters the ovule.
This figure summarises the life cycle of a seed plant. The blue circles named A and B represent the sexually mature individual of each phase of the life cycle.
1) What is this life cycle called?
2) Plant B is in the diploid phase. What is another name for this plant?
3) If A is the haploid phase, in which phase would you find sepals? Write just the letter of the individual corresponding to the correct phase
4) If B is the haploid phase, in which phase would you find synergids? Write just the letter of the individual corresponding to the correct phase
5) If B is the diploid phase, in which phase would you find the nucellus? Write just the letter of the individual corresponding to the correct phase
6) If A is the diploid phase, in which phase would you find the sperm cells? Write just the letter of the individual corresponding to the correct phase
7) If A is the diploid phase, in which phase would you find selection on flower colour? Write just the letter of the individual corresponding…
