Because fern spores germinate to produce gametophytes on which male and female reproductive organs are produced for sexual reproduction. Likewise in flowering plants large number of pollen grains are produced to ensure gametic union. Once the fertilization is achieved the sporophytic generation begins and there is surity of survival in diploid phase. Hence gametes are produced in plenty and zygotes and seeds in limited ammount.
Because the success rate for the spore finding the optimal conditions to germinate in are normally low. Therefore in order to improve it's chances of being able to reproduce the spore bearing plant (such as a fern) has to produce more spores to be successful
that's how they reproduce. they don't have flowers or fruit.
'cos so few of them survive
natural gases?
a seed contains a supply of food
spores
Ferns do not produce seeds. Only flowering plants produce seeds.Ferns reproduce by producing spores.
Mosses and ferns do not produce seeds; they are referred to as "seedless" plants, instead producing easily-damaged spores in great numbers for reproduction.
They reproduce by spores instead of seeds. Ferns also reproduce by spores, not seeds.
The saffron crocus is infertile, but gets by in dividing the bulb. No doubt there are many more.Various plants such as red rose, jasmine, grass etc. do not reproduce by seeds.There are also spore-bearing plants like ferns. Those spores are not the same as seeds.
conifers will not produce seeds. they produce cones
Horsetails produce seeds while mosses, ferns, and conifers produce spores.
Ferns do not produce seeds. Only flowering plants produce seeds.Ferns reproduce by producing spores.
Mosses and ferns do not produce seeds; they are referred to as "seedless" plants, instead producing easily-damaged spores in great numbers for reproduction.
I believe mosses and ferns release spores that become other mosses and ferns later on.
They reproduce by spores instead of seeds. Ferns also reproduce by spores, not seeds.
spores
There are plants with seeds and also those which produce spores or gametes for reproduction. Ferns, horsetails, mosses, and liverworts do not produce flowers or grow from seeds.
Ferns produce spores as their means of procreation as other plants produce seeds.
Mosses and Ferns both reproduce using spores instead of seeds or flowers. Mosses and Ferns are both plants. Mosses and Ferns are both made up of cells. Mosses and Ferns both photosynthesize.
Ferns and mosses grow from spores.
Ferns and mosses.
