What else can I help you with?
Do gymnosperms depend on water?
Yes, gymnosperms do not depend on water for fertilization like mosses or ferns do. They reproduce through the dispersal of pollen, which does not require water as a medium for transportation.
Were the first plants that did not require water for transferring sperm to eggs.?
Gymnosperms
Do bryophytes need water for fertilization?
Yes, bryophytes, like mosses and liverworts, require water for fertilization. This is because they rely on water to transport sperm from the male gametophyte to the female gametophyte for fertilization to occur.
What were the first plants that did not require water for transferin sperm to eggs?
The first plants that evolved to not require water for transferring sperm to eggs were the gymnosperms, such as conifers and cycads. Gymnosperms produce seeds that are not enclosed in a fruit, allowing them to be dispersed without the need for water for reproduction. This adaptation allowed them to colonize drier environments and diversify during the Paleozoic era.
Do angiosperms require water for fertilization?
Yes Edited answer: No, only crptogames need water for fertilization. In higher plants like angiosperms, the gametes are non-motile and male gametes reach near the egg for fertilization with the help of pollen tube.
Do gymnosperms depend on water?
Yes, gymnosperms do not depend on water for fertilization like mosses or ferns do. They reproduce through the dispersal of pollen, which does not require water as a medium for transportation.
When does fertilization occur during the gymnosperms life cycle?
it occurs when it occurs
How are gynosperms different from angia sperms?
The difference between gymnosperms and angiosperms is that gymnosperms develop cones as their seed to use in the fertilization process, and angiosperms produce flowers and fruits as their seed to use in the fertilization process.
Were the first plants that did not require water for transferring sperm to eggs.?
Gymnosperms
What you call seed producing plant?
It is called a seed plant, not to be confused with ferns and mosses whose gametes require water for fertilization. Seed plants can be either gymnosperms or angiosperms.Spermatophyte
Do bryophytes need water for fertilization?
Yes, bryophytes, like mosses and liverworts, require water for fertilization. This is because they rely on water to transport sperm from the male gametophyte to the female gametophyte for fertilization to occur.
What are the characteristics of a gymnosperms?
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)
Do all plants need water to make fertilization occur?
No, plants do not need water to make fertilization occur. Fertilization in plants involves the fusion of male and female gametes, typically through the transfer of pollen. Water is not directly involved in this process, although it is crucial for other aspects of plant growth and reproduction.
What were the first plants that did not require water for transferin sperm to eggs?
The first plants that evolved to not require water for transferring sperm to eggs were the gymnosperms, such as conifers and cycads. Gymnosperms produce seeds that are not enclosed in a fruit, allowing them to be dispersed without the need for water for reproduction. This adaptation allowed them to colonize drier environments and diversify during the Paleozoic era.
The gametophytes of gymnosperms are found inside reproductive structures called?
The gametophytes of gymnosperms live inside reproductive structures called cones. Gametophyte is the immediate result of fertilization in mosses.
Do angiosperms require water for fertilization?
Yes Edited answer: No, only crptogames need water for fertilization. In higher plants like angiosperms, the gametes are non-motile and male gametes reach near the egg for fertilization with the help of pollen tube.
Is anura fertilization internal?
As with most amphibians the fertilization is external. The female releases the eggs and the male fertilizes them. Amphibians, even toads, need water to reproduce.
