One main difference is that gymnosperms typically rely on wind for pollination, while angiosperms often rely on animals like bees for pollination. Additionally, gymnosperms have exposed seeds, while angiosperms have seeds enclosed within a fruit. Finally, gymnosperms do not produce flowers, while angiosperms do.
Pollination can occur through wind, animals (such as bees, butterflies, and birds), and self-pollination (where pollen is transferred from the anther to the stigma of the same flower or a different flower on the same plant).
From link below: There are several ways that seedless fruits can arise. They are usually an exception to the normal fertilization process. Most seedless fruits have what is termed parthenocarpy, where fruit form without fertilization, but pollination is sometimes required as stimulation. See related links below:
Angiosperms are often grouped according to the number of their seed leaves, the strength and composition of their stems, and the number of growing seasons they live.
The term spermatophytes refers to plants that produce seeds. This includes many types of plants, especially those that have flowers, but does not include those that reproduce by spores or in other ways.
Pea flowers are self-pollinating. About two days before the flower even opens, the anthers at the top of the stamen, which are the male part, burst and release the pollen. This sticks onto the stigma and fertilizes the ovary - these are the female parts. In many flowering plants, the stigma will not accept pollen from the same plant and fertilization must occur through other means, such as insect pollination after the flower opens. For gardeners, self-pollination is an advantage as it means more than one type of pea can be grown close together, as cross-pollination will not occur.
Flowers attract pollinators like bees and birds, facilitating pollination, while fruits protect and disperse seeds for the plant. These adaptations increase the chances of successful reproduction for angiosperms.
There are tons of ways that these plants evolved, but only one BIG change, they can drink their water, and live away from the rivers, ponds, lakes, and streams. They can grow where they thing is best suited to their needs.naww, the real answer is gymnosperms, bryophytes, angiosperms.
Pollination can occur through wind, animals (such as bees, butterflies, and birds), and self-pollination (where pollen is transferred from the anther to the stigma of the same flower or a different flower on the same plant).
conifers produce seeds from narrow needles, ferns do not

Two ways scientists can divide vascular plants are into seedless vascular plants and seed plants. Seedless vascular plants are comprised of the lycophytes (club mosses, spike mosses, and quillworts) and pterophytes (ferns, horsetails, and whisk ferns) and do not produce seeds. Seed vascular plants are comprised of gymnosperms (ginkgo, cycads, gnetophytes, and conifers) and angiosperms (flowering plants). Gymnosperms can be distinguished by their "naked seeds," while angiosperms produce flowers and fruits.

They produce seeds that are not enclosed by fruits.
habitats can differ temperture,moisture,and many other ways.
The two main types of pollination are self (or autogamous) pollination and cross (or heterogamous) pollination. Self pollination - is when pollination is tansfer from the anther to the stigma of the same flower. Cross pollintion - is when pollination is transfer from the anther to the stigma of another flower
