Characteristics of Gymnosperms sporophyte dominant: gametophyte very reduced multicellular female gametangium (archegonium) but no male gametangium (male gametophyte reduced to a few cells and a pollen tube) ovules (modified megasporangium) contain the female gametophyte; after fertilization and formation of zygote, then embryo becomes a seed. no external water required for fertilization vascular cambium leads to secondary growth (wood)

What two characteristics define gymnosperms?
Two characteristics that define gymnosperms are that they do not produce flowers or fruits and do not pollinate
Do gymnosperms share either of the two characteristics with angiosperms?
Yes, both gymnosperms and angiosperms are seed-producing plants. However, gymnosperms do not produce flowers, which is a characteristic unique to angiosperms.
Why don't gymnosperms share either of the two characteristics with angiosperms?
Gymnosperms and angiosperms differ primarily in their reproductive structures and methods of seed dispersal. Gymnosperms do not have flowers or fruits, which are defining characteristics of angiosperms; instead, they produce seeds that are often exposed on cones. Additionally, angiosperms rely on various pollinators for reproduction, whereas gymnosperms typically use wind for pollination. These differences highlight their distinct evolutionary paths and adaptations to their environments.
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 characteristics do all gymnosperms share?
They produce seeds that are not enclosed by fruits.
Why is a conifer a gymnosperm?
Conifers are gymnosperms because their seeds are not enclosed within a fruit. Instead, the seeds are found on the scales of cones, which are exposed and not protected by an ovary. This characteristic distinguishes them from angiosperms, which are flowering plants with seeds enclosed within a fruit.
What characteristics do all gymanosperms share?
Gymnosperms is Greek for naked seed. This means that the seeds have no protection around them. For example, a conifer's cone is encased, therefore it is not a gymnosperm.
What are the main characteristics used to differentiate between the angiosperms and gymnosperms?
Angiosperms are characterized by enclosed seeds within a fruit, while gymnosperms have exposed seeds on the surface of scales or cones. Angiosperms have flowers for reproduction, while gymnosperms have cones. Additionally, angiosperms have vessels in their xylem, while gymnosperms have tracheids. These are the main characteristics used to differentiate between angiosperms and gymnosperms.
