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.
Why do gymnosperms do not need water for fertilization?
Gymnosperms do not need water for fertilization because their male gametes are carried by pollen grains, which can be transported by the wind. This allows for fertilization to occur without the need for water.
How does water aid the fertilization of some organisms?
Water aids in the fertilization of some organisms by serving as a medium for the release and transportation of reproductive cells (such as sperm and egg) to meet and fuse. It also helps in the mobility of the sperm towards the egg, facilitating the fertilization process. Additionally, water can provide a stable environment for the reproductive cells to survive and function optimally during fertilization.
What process is absolutely necessary for sexual reproduction to occur in a life cycle but is not required for organisms that only reproduce asexually?
The process of meiosis is necessary for sexual reproduction to occur in a life cycle. Meiosis is a type of cell division that produces gametes with half the number of chromosomes, allowing for genetic diversity through the combination of genetic material from two parents. In asexual reproduction, organisms produce offspring that are genetically identical to the parent, so meiosis is not required.
When do humans need meiosis?
Meiosis produce haploid cells.So meiosis is used to produce sperms and ova.
What is a cell that you do not need a microscope to see?
A hen's egg, prior to fertilization.
Are cells that exit meiosis immediately capable of fertilization?
At the end of meiosis, haploid cells are produced. These cells need to further develop into mature gametes capable of fertilization, a process called gametogenesis.
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.
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.
Why do gymnosperms do not need water for fertilization?
Gymnosperms do not need water for fertilization because their male gametes are carried by pollen grains, which can be transported by the wind. This allows for fertilization to occur without the need for water.
What is an asexual cell?
An asexual cell is a type of cell that can reproduce without the need for fertilization or a partner cell. This can occur through processes like binary fission, budding, or fragmentation. Asexual reproduction results in offspring that are genetically identical to the parent cell.
Why does a female need a thick uterine lining if fertilization doesn't occur?
The thick uterine lining is necessary in preparation for a potential pregnancy. If fertilization does not occur, the lining is shed during menstruation. A thick lining ensures a hospitable environment for a fertilized egg to implant and grow.

Why do plants need meiosis?
Plants need meiosis for their sexual reproduction to produce gametes (eggs and pollen) that contain half the number of chromosomes found in somatic cells. This is essential for genetic diversity and the formation of seeds that can grow into new plants through fertilization.
Why do you need Meiosis?
