C) Asexual reproduction occurs in sponge Through the development of gems. Spongilla belongs to Porifera Porifera Sponge is a tool or cleaning aid made by soft porous material. Sponges are typically used to clean impervious surfaces and are particularly good at absorbing water and water-based solutions. Originally made from natural sponges, they are most commonly made from synthetic materials today. https://en.wikipedia.org › wiki › sponge_(tool)

door. … gemstones form in the middle layer of the body wall. So the correct answer is option ‘D’.

What kind of reproduction is involved in gemmule formation?

Gems are inner buds found in sponges, involved in asexual reproduction. It is an asexually reproducing cell mass capable of developing into a new organism, the adult sponge.

How are gems formed?

gem formation occurs in Freshwater consists of several species of sponges (eg Spongilia) and some aquatic species (eg sea sponges, figs), and various other types of poriferans. Organisms release gems that further generate new sponges.

Has gemmule formation been observed in Hydra?

Germ is defined as being present in sponge and participate in asexual reproduction. It is a cell mass capable of developing into a new organism, the adult sponge. … a newly created individual is a clone of its parent unit. Therefore, the correct answer is « Option D ».

Which organism produces gems as asexual reproductive structures?

What is an asexual reproductive structure?

asexual reproduction Individuals genetically identical to the parent plant. Roots such as bulbs, tubers, rhizomes and stolons reproduce asexually. Some plants can produce seeds without fertilization through apomixis, in which the ovule or ovary produces a new seed.

What is the reproductive type of yeast?

The most common form of vegetative growth in yeast is budding asexual reproduction, in which a small bud (also called a vesicle or daughter cell) forms on the parent cell. The nucleus of the mother cell divides into daughter nuclei and migrates into the daughter cells.

Do Hydras Sprout?

Organisms such as the hydra use regenerative cells to reproduce during the budding process.In the hydra, a Buds develop into products due to repeated cell divisions at a specific site. These shoots develop into tiny individuals that, when fully mature, break away from the parent and become new independent individuals.

What is sporulation?

Spore formation is A form of reproduction in which reproductive bodies called spores are present in sacs called sporangia. Once these spores mature, the sporangium bursts and these mature spores reach different areas by air, wind and water.

Where are the inner buds found?

Internal budding seen in Sporozoites etc., in which the parent species forms daughter cells or gems in its body. Gems are inner buds that contain various cells encapsulated in a protective cover.

Are sponges asexual?

Sponges reproduce asexually and sexuallyMost foraminifera that reproduce sexually are hermaphroditic and produce eggs and sperm at different times. … asexually reproduced sponges produce buds, or more commonly gems, which are packets of multiple different types of cells within a protective layer.

What are the types of reproduction?

There are two ways of reproduction: asexual and sexual reproductionAlthough asexual reproduction is faster and more energy efficient, sexual reproduction better promotes genetic diversity through new combinations of alleles during meiosis and fertilization.

What type of reproduction is found in Hydra?

Many Hydras reproduce when food is plentiful budding asexual. Buds form from the body wall, grow into small adults, and drop off when mature. When the hydra is fed, a new shoot will form every two days.

What is Gem Formation Level 12?

Full answer:- gem is Asexually formed clusters of cells capable of evolving into new organisms or adult freshwater sponges. Asexual reproduction is mainly by budding and spawning. Gems are inner buds produced by freshwater sponges.

Is regeneration a regeneration?

Regeneration is a special form asexual reproduction. Through regeneration, some organisms (such as starfish and salamanders) can replace injured or lost parts. … each spore is then released and able to grow into an entirely new organism without fertilization.

What is a motile asexual reproductive unit?

Answer: The active reproductive structures of algae and fungi that directly produce new individuals are called zoospores. It is an asexually moving spore.

What are the advantages of sporulation?

organism Don’t waste their energy Male and female gametes are produced unnecessarily. A large number of spores are produced in one sporangium. Spores do not need any medium to spread. They are round and lightweight so that sprouting can be transferred easily.

What is an example of sporulation?

example is Conidial fungi Aspergillus and Penicillium, in which filamentous spore formation appears to be the predominant mode of reproduction. Other fungi, such as Ascomycetes, utilize mitotic and meiotic spores.

What is sporulation to give two examples?

For example, germ are unicellular organisms that reproduce by sporulation, while fungi such as Rhizopus (bread mold) and Mucor, and non-flowering plants such as multicellular organisms that reproduce by sporulation.[=>TheunderlinedpartisyouranswerNamelyfernsandmosses[=>UnderlinedpartisyouranswerieFernsandmosses[=>下划线部分是你的答案。即蕨类植物和苔藓。[=>UnderlinedpartisyouranswerieFernsandmosses

What are the benefits of budding reproduction?

As a means of reproduction, sprouting has many benefits.For example, in plants, budding is A faster and more efficient form of grafting that allows breeders to transfer the desired characteristics of a given bud onto the stem of another plant.

What is budding?

Germination, in biology, A form of asexual reproduction in which new individuals are Some reproductive anatomical points of the parent organism. …In horticulture, the term budding refers to a method of plant propagation in which the bud of the plant to be propagated is grafted onto the stem of another plant.

What are the steps of germination?

1. Preparation of rootstocks. …
2. Prepare the scion. …

What is the process of yeast asexual reproduction?

Yeast reproduces through a process called asexual reproduction bud (See Figures 8.2.1 and 8.2.6). When the nucleus divides, a bud forms on the outer surface of the parent cell.
