What is the clases of gymnosprem?
Gymnosperms are divided into four main classes: Coniferopsida (conifers), Cycadopsida (cycads), Ginkgopsida (ginkgo), and Gnetopsida (gnetae). Each class includes different groups of gymnosperms with distinct characteristics and reproductive structures.
How many groups of gymnosperms exist today?
there are alot of different species but there is about the same number of angiospems so there is about 200,000-300,000
What are 2 groups of vascular plants that produce seeds?
Angiosperms (flowering plants) and gymnosperms (conifers, cycads, ginkgo) are two groups of vascular plants that produce seeds. Angiosperms have seeds enclosed within a fruit, while gymnosperms have seeds not enclosed, usually in cones.
What are two groups of plants that make seeds?
Angiosperms and gymnosperms are two groups of plants that produce seeds. Angiosperms, also known as flowering plants, have seeds enclosed within a fruit. Gymnosperms, such as conifers and cycads, have seeds that are not enclosed within a fruit.
A type of gymnosperm?
One common type of gymnosperm is the pine tree, which produces its seeds in cones rather than within flowers or fruit. Gymnosperms are seed-producing plants with naked seeds that are not enclosed in a fruit. They include conifers, cycads, ginkgo, and gnetophytes.
Is a fir a gymnosperm?
Ferns are not gymnosperms. Gymnosperms are divided into 4 groups,cycads,ginkgoes,gnetophytes,and conifers.
Briefly describe the four groups of gymnosperms Which group is the largest and most economically important?
The four groups of gymnosperms are cycads, ginkgo, gnetophytes, and conifers. Conifers, which include pine, spruce, and fir trees, are the largest and most economically important group of gymnosperms due to their widespread distribution and economic significance in industries such as timber, paper production, and horticulture.
What are the four groups of gymnosperms?
present day gymnosperms are divided into the four following phyla: 1-Cycadophyta: palm-like trees of tropics/subtropics 2-Ginkgophyta: only a single species: Ginkgo biloba 3-Coniferophyta: cone bearing trees, evergreens: pines, firs, spruce 4-Gnetophyta: consists of 3 genera: a. welwitschia: in African deserts with only 2 long strap-like leaves b. Ephedra: desert shrub, souce of alkaloid ephedrine - used to treat congestion of hay fever, asthma c. Gnetum: trees or vines with large leathery leaves

What type of seeds do gymnosperms produce?
Gymnosperms produce naked seeds, meaning their seeds are not enclosed in a fruit. These seeds are often found on the surface of specialized structures, such as cones or scales, instead of being fully enclosed. Examples of gymnosperms include conifers, cycads, and ginkgo trees.

What are the four groups of terrestrial plants?
The four groups of terrestrial plants are bryophytes (mosses and liverworts), pteridophytes (ferns and their relatives), gymnosperms (conifers and cycads), and angiosperms (flowering plants). These groups vary in their reproductive structures and evolutionary history.
What are the similarities of ginkgo biloba with other groups of gymnosperms?
They are all conifers. They are all conifers.

What are the major groups of plantae?
The major groups of Plantae are bryophytes (mosses, liverworts, and hornworts), pteridophytes (ferns and horsetails), gymnosperms (conifers, cycads, ginkgoes), and angiosperms (flowering plants). Each group has unique characteristics and reproductive strategies.
