The maturation time for seeds of gymnosperms can vary widely depending on the species, typically ranging from several months to a few years. For example, the seeds of some conifers may take about 6 to 18 months to mature, while others, like pines, can take up to three years. Environmental conditions and specific growth patterns of the species also play a significant role in this maturation process.

What do angiosperms produce that gymnosperms do not?
Angiosperms produce flowers and fruits, which serve as reproductive structures and protect the seeds. Gymnosperms do not produce flowers or fruits; instead, they produce cones to hold and disperse their seeds.
Which group of plants common during the triassic period had seeds lacking a protective outer coat?
Gymnosperms, such as cycads and ginkgoes, were common during the Triassic period and had seeds lacking a protective outer coat. They were some of the first seed plants to evolve, and their seeds were exposed on the surface of cones or other structures.
Do only gymnosperms reproduce with spores?
No, gymnosperms do not reproduce with spores. Gymnosperms reproduce through seeds, which are typically produced in cones or sometimes in fleshy fruit-like structures. Spores are used in the reproduction of some non-seed plants like ferns and mosses.
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
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 do gymnosperms spread their seeds?
Gymnosperms spread their seeds through various methods such as wind dispersal, animal dispersal, and water dispersal. For example, conifers produce lightweight seeds with wings that are dispersed by the wind, while some gymnosperms rely on animals to eat and then disperse their seeds.
What are some characteristics of gymnosperms?
Gymnosperms are seed-producing plants with seeds not enclosed in fruit. They typically have needle-like or scale-like leaves and reproduce through cones. Gymnosperms include conifers, cycads, ginkgo, and gnetophytes.
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.
Why do female pine cones remain on tree after pollination?
Unlike other gymnosperms, in which pollination, fertilization, and seed maturation occur within the same year, the pines have an extended reproductive cycle of 14-20 months. (The period elapsed between the appearance of the ovulate cone and the maturation of pine seeds in those cones. Fertilization takes place about 1 year after pollination, and seed maturation takes several additional months). Some seeds are shed as soon as they mature, whereas others remain within the female cones for weeks, months, or even years before being shed.
How do you use gymnosperms in a sentence?
"Gymnosperms are a group of spore-bearing, non-flowering plants; common examples of Gymnosperms are the Pine, Cypresses and Spruce."
