What is a gymnsperm?
gymnosperms are amember of the plantaw kindom that has a vascular system and produces naked seeds...they are mostly conifers. there are many species some are pines, spruces redwoods and cedars
What do angiosperms produce that gymnosperms do not?
Angiosperms produce ovary and embryo sac which gymnosperms do not.
How do you call a mature ripened ovary of a plant?
A mature ripened ovary of a plant is called a fruit. It develops from the ovary after pollination and fertilization, typically containing seeds. Some examples of fruits are apples, oranges, and tomatoes.
How does seeds develop?
some plants have seeds in them and they burp them out and some fruits have seeds in them and if a birds eats the fruit the bird could drop one of the seeds and the seed would then be planted.
How long does it take a spore to develop into a mature plant?
A spore is a reproductive structure that is adapted for dispersion and surviving for extended periods of time in unfavorable conditions. Spores form part of the life cycles of many plants, algae, fungi and some protozoans. A chief difference between spores and seeds as dispersal units is that spores have very little stored food resources compared with seeds.

What are some different types of gymnosperms?
things that produce naked seeds like pine cones
Can Gymnosperms CAUSE illness or disease?
Some Gymnosperms cure others kill
What plants are gymnosperm?
Gymnosperms are plants that have seeds, in the form of seed pods or cones. Some types are ginkgo, pine, and cypress trees.

How do gymonosprems seeds differ from angiosprem seeds?
In Gymnosperms, the seeds do not develop in an ovary - they aren't inside a fruit. Gymnosperm seeds develop either on the surface of scale/leaf-like appendages of cones, or at the end of short stalks. Two examples are conifers and cycads. In Angiosperms (flowering plants), the seeds are contained within some kind of fruit, the ovary.
Does sexual reproduction of plants use seeds?
Not all plants use seeds! seeds have recently evolved in plants, in fact gymnosperms and angiosperms are the only classifications that use seeds! however, plants such as ferns and mosses use spores! you also need to remember that not all plants reproduce sexually! some reproduce asexually!
What do angiosperms produce that gymnosperms do not?
Angiosperms produce ovary and embryo sac which gymnosperms do not.
What kinds of a seed do gymnosperms have?
the seed is produced inside a cone-like structure such as a pine cone hence the name "conifer." Some conifers, such as the Yew and Ginko, produce their seeds inside a berry-like structure.
Why are angiosperms more successful than gymnosperms?
Angiosperms contain both seeds and flowers, while gymnosperms only contain seeds. Instead of relying on wind pollination, angiosperms attract bees and other insects (with the colors and decor of their flowers), whom which collect and distribute pollen (insect pollination). Insect pollination is more reliable than wind pollination.

What is another name for a non-flowering plant?
Plants that do not produce "typical" flowers include: bryophytes (mosses, liverworts, hornworts) and pteridophytes (ferns). There are also gymnosperms that are not "true flowering plants", but produce cones.
