What has a single nucleus in each cell?
A eukaryotic organism has a single nucleus in each of its cells. Examples of eukaryotic organisms include animals, plants, and fungi. Each cell's nucleus contains the genetic material, such as DNA, that controls the cell's activities.
How many nuclei in each amoeba cell?
Each amoeba cell typically contains one nucleus. This single nucleus is responsible for controlling the cell's activities and regulating its genetic material. However, there are some species of amoeba that can have multiple nuclei, but this is less common. Overall, the standard for most amoebas is a single nucleus per cell.
What are the single hole nuclei and example?
Single-hole nuclei are atomic nuclei that have one less electron than protons, resulting in a net positive charge. An example of a single-hole nucleus is hydrogen-1, which has one proton but zero electrons, making it a hydrogen cation (H+).
What are single hole nuclei?
Single-hole nuclei refer to atomic nuclei that have lost an electron, leaving behind a hole in one of their electron shells. These nuclei exhibit unique properties and are often studied in nuclear physics to better understand the structure and behavior of atoms. They are also used in studies related to nuclear reactions and nuclear astrophysics.
How many nuclei are in a stentor?
A Stentor, a genus of single-celled organisms known for their trumpet-like shape and cilia, typically contains a single macronucleus and one or more micronuclei. The macronucleus is responsible for regulating the cell's metabolic activities, while the micronuclei play a role in reproductive processes. Thus, a Stentor generally has one prominent nucleus and additional smaller nuclei, depending on the species and its reproductive state.
What is meant by monosporic development of female gametophyte?
The female gametophyte or the embryo sac develops from a single functional megaspore. This is known as monosporic development of the female gametophyte. In most flowering plants, a single megaspore mother cell present at the micropylar pole of the nucellus region of the ovule undergoes meiosis to produce four haploid megaspores. Later, out of these four megaspores, only one functional megaspore develops into the female gametophyte, while the remaining three degenerate
What have two nuclei what are their names and functions?
Most ciliates have two nuclei: a macronucleus that contains hundreds of copies of the genome and controls metabolisms, and a single small micronucleus that contains a single copy of the genome and functions in sexual reproduction.
What is female gametophyte?
Embryo sac is the female gametophyte of flowering plants. Situated in the flower. It is dependent on the sporophyte (what we call plant) for nutrition. here the gametophyte is reduced and sporophyte is dominant.In lower plants the female gametophyte is prominent and independent where it can photosynthesize. Usually it is called as a thallus. Here the sporophyte is reduced and the gametophyte is dominant.
What nuclei has 79 protons?
It is gold metal. It contains 79 protons in a single atom.
How many nuclei are formed by meiosis?
Meiosis forms four nuclei from a single parent cell. Each of these nuclei contains half the number of chromosomes as the parent cell, resulting in genetic diversity through the process of recombination.
What has a single nucleus in each cell?
A eukaryotic organism has a single nucleus in each of its cells. Examples of eukaryotic organisms include animals, plants, and fungi. Each cell's nucleus contains the genetic material, such as DNA, that controls the cell's activities.
What type of muscle is involuntary single-ovoid nuclei slow-twitch and has spindle-shaped fibers?
The type of muscle described is smooth muscle. Smooth muscle is involuntary, has single-ovoid nuclei, and contains slow-twitch fibers with spindle-shaped cells. It is found in organs such as the digestive tract and blood vessels.

However, there are some species of amoeba that can have multiple nuclei, but this is less common. Overall, the standard for most amoebas is a single nucleus per cell.

What are four advantages the plant gains by the miniaturization of the gametophyte?
their tiny gametophytes can develop from spores retained within the sporangia of the parental sporophyte. this arrangement protects the delicate female (egg-containing) gametophytes from environmental stressesSoD. megaspores for PF students.
Is nuclei plural or singular?
Nuclei is plural. Nucleus is singular.
What are single celled orginisms without a nuclei?
I think it is privations
