What advantage did gymnosperms have over primitive types of plants?
Gymnosperms have a survival advantage over angiosperms only in extremely cold or dry conditions. This ability to survive cold or dry weather is due to a thick wax cuticle on the needles of conifers, which prevents dehydration through evaporative loss.
What advantages do the gymnosperms have in their adaptation to land?
Compared to ferns, gymnosperms have three additional adaptations that make survival in diverse land habitats possible. These adaptations include an even smaller gametophyte, pollen, and the seed. Gymnosperms are plants that bear seeds that are "naked," meaning not enclosed in an ovary.
How are gymnosperms better adapted to life on land?
Gymnosperms are seed plants adapted to life on land; thus, they are autotrophic, photosynthetic organisms that tend to conserve water. They have a vascular system (used for the transportation of water and nutrients) that includes roots, xylem, and phloem.Jun 8, 2022
What advantage did gymnosperms have over other land plants that allowed them to live in drier parts of the land?
Pollen grains could travel great distances to spread plant genes and seeds provided a protective coat around embryos. Seeds also built in a higher resistance to drought, allowing germination when conditions were optimal. These factors pushed gymnosperms to expand into much drier terrestrial environments.Jan 23, 2021
Why can gymnosperms live in dry environments?
Conifers, however, still dominate in cold and dry environments, as a waxy covering (cuticle) on their needle-like leaves allows them to survive in more extreme conditions than the angiosperms.
What advantage do gymnosperms have over ferns?
What advantage did gymnosperms have over ferns? Gymnosperms produce pollen and do not require water to reproduce. Both seed protection and seed dispersal are correct.
How are gymnosperms different from ferns?
Ferns are plants that do not bear flowers. They do not have any seeds as well. In this regard, their mode of reproduction is through spores. Gymnosperms on the other hand have seeds, although they are not put inside an ovary.
What is the reproductive advantage that gymnosperms have over ferns?
Gymnosperms possess several key evolutionary innovations compared to earlier groups such as the clubmosses and ferns. They produce sperm-containing pollen, which is carried through the air by the wind to the female. This innovation has freed these plants from the need for water for sexual reproduction.
Why are gymnosperms more successful than ferns?
Compared to ferns, gymnosperms have three additional adaptations that make survival in diverse land habitats possible. These adaptations include an even smaller gametophyte, pollen, and the seed. Gymnosperms are plants that bear seeds that are "naked," meaning not enclosed in an ovary.
What do gymnosperms produce that ferns do not?
While ferns produce one type of spore, making them homosporous, gymnosperms and other seed plants produce two types of spores (heterosporous), megaspores, which give rise to female gametophytes inside the ovule, and microspores, male gametophytes inside the pollen grain.Jan 13, 2022
