a. What happens to the ovary after fertilization?
b. What is the mode of reproduction in fungi, ferns and mosses?
c. Where are pollen grains produced in a flower?
d. What do we call to the fertilized egg?
Name the seeds which get dispersed when the fruit burst
Answers
Answer:
a) Answer : After fertilization occurs, each ovule develops into a seed. Each seed contains a tiny, undeveloped plant called an embryo. The ovary surrounding the ovules develops into a fruit that contains one or more seeds.
b) Answer : Mosses, ferns, and fungi all reproduce with spores. Spores are an important adaptation that allowed the ancestors of these organisms to reproduce on land. A spore is a single reproductive cell that is pro- tected by a hard, watertight covering. The covering prevents the cell from drying out.
c) Answer : Pollen grains are produced in stamen in flower.
d) Answer : Fertilization happens when a sperm cell successfully meets an egg cell in the fallopian tube. Once fertilization takes place, this newly fertilized cell is called a zygote.
e) Answer : Pea and bean are two plants whose seeds are dispersed by explosion of their fruits.
Answer:
1) Fertilization occurs when one of the sperm cells fuses with the egg inside of an ovule. After fertilization occurs, each ovule develops into a seed. Each seed contains a tiny, undeveloped plant called an embryo. The ovary surrounding the ovules develops into a fruit that contains one or more seeds.
2) Mosses, ferns, and fungi all reproduce with spores.
3) Stamen
Stamen: The pollen producing part of a flower, usually with a slender filament supporting the anther. Anther: The part of the stamen where pollen is produced
4) a) Fertilization happens when a sperm cell successfully meets an egg cell in the fallopian tube. Once fertilization takes place, this newly fertilized cell is called a zygote.
b) Pea and bean are two plants whose seeds are dispersed by explosion of their fruits.
