Why nucleus is in the middle of a cell?

Why nucleus is in the middle of a cell?

The nucleus is located toward the center of the cell because it controls all of the cell’s movements, the cell’s feeding schedule and the cell’s reproduction. Its central location enables it to reach all parts of the cell easily. Eukaryotic cells typically only have one nucleus.

How does the nucleus help the organism?

The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information. Nucleoli are small bodies often seen within the nucleus.

Why nucleus is located at the peripheral region in plant cells and at the Centre in animal cells give reason?

The nucleus is an organelle that contains the genetic information for that organism. In an animal cell, the nucleus is located in the central region of the cell. In a plant cell, the nucleus is located more on the periphery due to the large water-filled vacuole in the center of the cell.

What do you think is the advantage of having membrane bound nucleus as opposed to DNA that is freely floating in the cell cytoplasm?

Explanation: As the DNA is present in the nucleus, there is compartmentalisation and the process becomes more efficient without the interaction of external bodies. The membrane of the nucleus protects the DNA from injuries.

Why in an animal cell the nucleus is present in the Centre of the cell where as in the plant cell it is present at the periphery of the cell?

Answer: Nucleus is towards the periphery in the plant cell because in a plant cell,a large vacoule is present which occupies half of the space of a cell,thereby pushing the nucleus towards the corner of the cell.

What is the major benefit of having membrane-bound organelles?

Cells can confine potentially harmful proteins and molecules in membrane-bound organelles, protecting the rest of the cells from their harmful effects. For example, the lysosome, which is a membrane-bound organelle, contains many enzymes that digest protein, nucleic acids and lipids.

What is the importance of a membrane-bound nucleus?

Most are membrane-bound structures that are the sites of specific types of biochemical reactions. The nucleus is particularly important among eukaryotic organelles because it is the location of a cell’s DNA.

What is nucleus state the importance of nucleus?

The nucleus has very important roles to play. As it contains genetic material, it coordinates cell activities like protein synthesis and cell division. control of the protein and enzyme synthesis. control of cell division and cell growth.

What are the functions of the nucleus of a cell?

Namely, these functions are: control of the genetical information of the cell and thus the heredity characteristics of an organism, regulation of the transcription of the mRNA to protein When a cell is histologically stained, the nucleus normally appears as a large, dark organelle, mostly at or near the centre of a cell .

How is the nucleus the control center of an organism?

The nucleus functions the selective transportation of regulatory factors and energy molecules through nuclear pores. The nucleus is the control center of an organism as it regulates the integrity of genes and the gene expression. The nucleus contains all the genetic material of an organism like DNA, genes, chromosomes etc.

Are there any organisms that only have one nucleus?

Only the cells of advanced organisms, known as eukaryotes, have a nucleus. Generally there is only one nucleus per cell, but there are exceptions, such as the cells of slime molds and the Siphonales group of algae.

Which is an example of a nucleus with more than one nucleus?

It contains two nuclei at a time. The examples are one paramecium (have mega and micronucleus), balantidium, and liver cells and cartilage cells. It is also known as the polynucleated cell which contains more than 2 nuclei at a time. For example, plants latex cells and latex vessels.
