What does flowers does in plants?
Flowering plants do not have a sporophyte. They have antheridium and archegonium to produce their gametes. Sporophyte is found in ferns, mosses, club mosses, lycophytes, etc but not in flowering plants. Flowering plants produces pollen while a sporophyte produces spores
What is the importance of meiosis in sexual reproduction of flowering plants?
Meiois is the process in which diploid cells divide to become haploid gametes (or sex cells)
When does fertilization happen in plants?
When male and female gametes unite to form the zygote, it is called fertilization. In flowering plants it is followed by pollination and pollen germination.
How is fertilization in flowering plants different from fertilization in other plant groups?
Fertilization in flowering plants is achieved by transferring the male gamete through pollen tube whereas in nonflowering plants the male male gametes are motile and transferred in aqueous medium.
Why can flowering plants be fertilized without water?
The male gametes in most of the non-flowering plants are motile and these are carried to the female gamete by their own movement in presence of water.
In flowering plants the sporophyte does what?
Flowering plants do not have a sporophyte. They have antheridium and archegonium to produce their gametes. Sporophyte is found in ferns, mosses, club mosses, lycophytes, etc but not in flowering plants. Flowering plants produces pollen while a sporophyte produces spores
What are the main features of flowering plants?
They have true roots, stems and leave and reproduce (sexually) by producing haploid gametes.

What is the difference between cone bearing plants and flowering plants?
Cone bearing plants do not depend on Insects, birds or mammals for the transfer of their male gametes or spores. The cone bearing plants are lower in evolutionary ladder than the flowering plants.
How is fertilization in flowering plants different from fertilization in other plant groups?
Fertilization in flowering plants is achieved by transferring the male gamete through pollen tube whereas in nonflowering plants the male male gametes are motile and transferred in aqueous medium.
What is the similarity in fertilisation between the sexual reproduction of flowering plants and humans?
Fertilization is the union of male gamete (sperm) with the female gamete or egg. Two male gametes in flowering plants are transferred through the pollen tube and there is double fertilisation. That is, out of two male gametes one fuses with the egg to form zygote and the other with secondary nucleus to form primary endosperm cell. In humans several male gametes swim through their tail to reach the ovum and only one fuses with it to form zygote.
Gametes are said to be?
sex cells, like sperm or eggs in humans. They are normally haploid.
Why can flowering plants be fertilized without water?
The male gametes in most of the non-flowering plants are motile and these are carried to the female gamete by their own movement in presence of water.
What is used to make sex cells called gametes?
Yes. Gametes are specialized sex cells that are only found in the reproductive organs of the human body. They are different from somatic cells (or body cells) because they only contain half of a set of chromosomes in their nucleus (23 rather than 46). Two gametes unite to form a zygote and thus a full set of 46 chromosomes come together.
