Depending on the species, fertilization can occur internally or externally. Water aids the fertilization of some organisms because organisms that reproduce externally need water for fertilization to occur.
Egg fertilization typically involves the union of a sperm and an egg cell, resulting in multicellular organisms, such as animals. In contrast, unicellular organisms, like bacteria and protists, reproduce asexually through processes such as binary fission or budding, where no fertilization occurs. Therefore, the concept of egg fertilization does not apply to unicellular organisms, as their reproductive methods do not involve the combination of gametes.
Gametes are specialized cells that are essential for sexual reproduction. They are responsible for carrying genetic information from parents to offspring, combining during fertilization to create a new individual with a unique combination of genetic traits.

The purpose of the cell membrane to pond organisms is to separate and protect contents in the pond cell from those outside the cell membrane.
The different types of sexual reproduction in organisms include internal fertilization, external fertilization, and self-fertilization.

Most organisms develop through a process that starts with the fertilization of an egg
Internal fertilization .
External fertilization is not possible in land-dwelling organisms primarily due to the risk of gametes drying out in the air, which reduces the chances of successful fertilization. Additionally, the lack of a consistent aquatic environment makes it challenging for sperm to reach and fertilize eggs. These organisms have adapted to internal fertilization methods, which provide a more protected environment for developing embryos.

the purpose of the of pollen tube is to fuse or join with the ovules to cause fertilization.
The main purpose of the reproductive system in organisms on Earth is to facilitate the continuation of species through the process of reproduction. This system enables the production of gametes (sperm and eggs) and supports fertilization, leading to the development of new individuals. Additionally, reproductive strategies can enhance genetic diversity, which is crucial for adaptation and survival in changing environments. Overall, the reproductive system plays a vital role in the life cycle and evolution of organisms.
Parthenogenesis is a type of asexual reproduction where there is no fertilization needed. Some organisms that demonstrate this are komodo dragons and water fleas.
The purpose of fertilization is the first step in the reproduction of new offspring, which contributes to the longevity of different species, so that they do not become extinct.i.e. human fertilization occurs when a haploid sperm cell & haploid secondary oocyte produce a diploid nucleus
Gametes are specialized cells that are essential for sexual reproduction. They are responsible for carrying genetic information from parents to offspring, combining during fertilization to create a new individual with a unique combination of genetic traits.
The purpose of fertilization is to combine genetic material from two individuals to create a new organism with a unique set of genes. This process ensures genetic diversity and allows for the continuation of the species.
