Reproduction
Like all other organisms, sponges need to produce and generate offspring. However, their methods of performing such quintessential tasks are very divsersified. Unlike humans, porifera may propogate both sexually and asexually. The processes may be oviparous, where there is a mass spawning of eggs and sperm, or vivivparous, where the cells are incubated prior to releasal. In addition, sponges may commence to reproduce at the age of three years. The genetics systematics of porifera are fundamentals of new scientific research throughout the world. By revealing and untangling the convoluted and cryptic reproduction patterns of porifera, it is theorized that such research may be implemented to benefit humans. Below is a comparison of sponge reproduction processes. (To learn about recent research, follow the link to the current studies section of this site.)
Asexual methods of reproduction
1) Budding and Gemules- A mini-sponge branch forms on the exterior of the sponge. After a period of time, currents may cause this to break off from the rest of the sponge.
2) If a conglomeration of sponge cells is extracted from the main body of the sponge, it will develop into another porifera.
Sexual methods of reproduction
1) Basically, most sponges are hermoprhoditic (being of both genders or able to change between these genders). Eggs and sperm are released, and these cells are cross fertilized. Whence, they float to some uninhabited section of the ocean floor and initiate their life as a sponge. This is actually synchronized between species.
Two important terms to remember are viviparous and oviparous. Viviparous sponges incubate the eggs within their branches before releasal. Oviparous simply release the sponges.
yes
Asexual .... probably .... i mean could you imagine sponges having sex??
Sponges have three asexual methods of reproduction: by fragmentation; by udding; and by producing gemmules.
sexual and asexual
There are two main methods. They are sexual and asexual reproduction.
The two methods of reproduction are sexual (male and female) and asexual (no male and female . . . but simply splitting, for instance.)
Asexual reproduction is two words. An example sentence is "I wonder why some animals have asexual reproduction".
These are two examples of asexual reproduction
Asexual and sexual reproduction, two methods of reproduction among animals, produce.
The main categories of reproduction are sexual and asexual. Two types of reproduction are asexual and sexual reproduction.
Asexual reproduction is a method by which one individual produces offspring that are genetically identical to itself. Asexual reproduction occurs through a process of cell division called mitosis. Asexual reproduction occurs in plants as well as in some animals, including sponges. If two cats are involved in reproduction, the process must be sexual.
true.budding and regeneration are asexual methods.
sexual reproduction and asexual reproduction
what are the three types of asexual reproduction? AnswerConjugation and fertilization are two
The difference between sexual and asexual is that in sexual reproduction, there are two parents, and in asexual, there is only one. In sexual reproduction, the two parents mix up their genes and produce a mix between the two parents. Asexual reproduction produces an exact match of the parent, since there were only the genes from the one parent.
