A flower produces pollen for pollination, so it needs a large amount of pollen to increase the chances of a pollinator, such as a bee or butterfly, getting pollen on it to spread to other flowers when it comes in contact with the flower.
Ovules are located inside the ovary of a flower. The ovary is what later becomes the fruit of the plant. The size of the fruit depends on how many ovules there are inside the flower. If there are five ovules, there will be five fruits, but each fruit will be smaller than a flower with only two ovules, and natural selection dictates that the larger the fruit, the more appealing it will be to any herbivores or omnivores that pass-by.
So, based upon this information, it is a requirement for there to be fewer ovules than pollen.

∙ 12y agoIt is all to do with dispersal. Because gymnosperms (Flowerless, Vascular Plant) use wind as there method of getting the Microspore (sperm) and the Megaspore (eggs) together it relies more so upon probability of the two meting and therefore to hedge your bet you'd produce more pollen grains.
Contrast this with a flowering plant, they rely on organisms such as bees to transport the pollen in a far more direct manner. A bee has to go to more than one flower to get enough nectar for the hive.

What kind of spores are produced by flowering plants?
flowering plants don't produce spores - they produce pollen
Is it true most bacteria produce pollen to make seeds?
No, they do not. They reproduce by budding. Pollen is produced by flowering plants.
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
Is a giant sequoia dicot?
Short AnswerGiant Sequoia (Sequoiadendron giganteum) is neither a monocot nor a dicot. The terms "monocot" and "dicot" apply only to flowering plants. Sequoia are not flowering plants. They are conifers.Longer AnswerTaxonomists recognize six major divisions of seed-bearing plants.Division Angiospermae (the angiosperms or "flowering plants") can be further divided into the monocots and the dicots based on certain morphological characteristics including embryonic leaf number. Palms and grasses are familiar monocots. Oaks and peanuts are familiar dicots.Sequoia are in Division Pinophyta (the conifers) along with pines, cedars and other cone-producing trees and shrubs. Like angiosperms, conifers produce pollen and seeds that contain embryonic plants. But the conifers' reproductive structures are contained within cones rather than flowers. Conifer seeds also lack endosperm and conifers do not produce fruit.
Do pollination take place in ferns?
Yes they do. Most commonly called spoaring. They spread spoares in the air.
Do conifers produce seeds?
conifers will not produce seeds. they produce cones
What kind of spores are produced by flowering plants?
flowering plants don't produce spores - they produce pollen
Do conifers have seeds?
Conifers don't produce real flowers. However they do produce "flower-like pollen."
Do conifers reproduce using seeds or spores?
spores
What is the characteristic of the flowering plants?
Primary reproductive organ is the flower Produce pollen Produce ovules Produce seed
Is it true most bacteria produce pollen to make seeds?
No, they do not. They reproduce by budding. Pollen is produced by flowering plants.
Do plants have reproductive organs Explain how they reproduce?
Yes, most plants have reproductive organs. In flowering plants these are the anthers which produce pollen and the ovaries which produce ovules, both of which are found in flowers. Reproduction occurs when pollen is transferred to the stigma of a flower and fertilization ensues. In ferns the corresponding parts are antheridia and archegonia which are on the undersides of the fronds. Mosses are similar, whilst conifers are more like flowering plants with the cones taking the place of flowers. By contrast, very simple plants reproduce by simple fission.
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 is pollen grain like from non flowering plants?
Pollen grains from plants which do not flower are very similar to that of flowering plants, except they are different.
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
How do conifers differ from flowering plants?
Conifers are different to flowering plants because conifer reproduce with seed cones. The pollen come out of the male cone and fertilises the ovule or female cone. Conifers are also different because the have needle like leaves but I'm not sure if that's relevant... Any way, I hope this has helped. You might have to do a bit more research. Conifers also have naked seeds, whereas flowering plants have their seeds encased in flesh (fruit). Although some conifers like the plum pines also have fruit. Also flowering plants have... flowers. And non flowering plants don't. But I thought that was obvious.
How is the life cycle of an evergreen tree similar to the life cycle of a flowering plant?
It's not because flowers wither and come back when trees stay green all year.:)
