A nucleus (pl. nuclei) is essentially the brain or power center of a living eukaryotic cell. Comprised of cell's bulk of genetic material, it oversees the processes of the cell from DNA storage and eventual replication to control over all cell functionality. The nucleus itself consists of a double membrane, nuclear envelope, and the nucleoskeleton, all of which are responsible for isolating it from the rest of the cell's contents for optimum stability.

What happens to the polar nuclei in an embryo sac?
The polar nuclei in an embryo sac are involved in the process of double fertilization in plants. One of the polar nuclei fuses with a sperm cell, leading to the formation of endosperm tissue, while the other polar nucleus may fuse with another sperm cell or remain unfertilized. The endosperm provides nutrients for the developing embryo in seeds.
What is the definition of peripheral nuclei and how do they function within a cell?
Peripheral nuclei are nuclei located at the edge of a cell, away from the center. They play a role in regulating gene expression and cell function by interacting with other cellular structures and molecules. These nuclei help in coordinating various cellular processes and maintaining the overall function of the cell.
What is the significance of peripheral nuclei in cellular biology?
Peripheral nuclei in cellular biology are significant because they play a role in regulating gene expression and cellular function. These nuclei are located at the edge of the cell and are involved in processes such as DNA replication, transcription, and cell division. Their positioning within the cell can impact how genes are activated or silenced, influencing the overall function and behavior of the cell.
What is the role of nuclei in cardiac muscle function?
The nuclei in cardiac muscle cells play a crucial role in regulating the cell's functions, such as protein synthesis and gene expression. They help maintain the cell's structure and function, allowing the heart to contract and pump blood effectively.
What is the function of the basal nuclei?
The basal nuclei are involved in the planning and execution of movement, as well as in some aspects of cognition and emotion. They help regulate muscle tone, coordinate movements, and inhibit unwanted movements. Dysfunction of the basal nuclei can result in movement disorders such as Parkinson's disease.
What happen to polar nuclei after fertilization?
endosperm
What happens to the polar nuclei in an embryo sac?
The polar nuclei in an embryo sac are involved in the process of double fertilization in plants. One of the polar nuclei fuses with a sperm cell, leading to the formation of endosperm tissue, while the other polar nucleus may fuse with another sperm cell or remain unfertilized. The endosperm provides nutrients for the developing embryo in seeds.
What is the definition of peripheral nuclei and how do they function within a cell?
Peripheral nuclei are nuclei located at the edge of a cell, away from the center. They play a role in regulating gene expression and cell function by interacting with other cellular structures and molecules. These nuclei help in coordinating various cellular processes and maintaining the overall function of the cell.
Are all nuclei the same size in cells?
No, nuclei in cells are not all the same size. Nuclei can vary in size depending on the type of cell and its function.
Is C13H18O2 polar or non polar?
it is polar since it has carboxylic acid (propanoic acid) function
What has the author Jingxia Zhao written?
Jingxia Zhao has written: 'Origin of condensation nuclei in the springtime polar stratosphere' -- subject(s): Atmospheric composition, Polar regions, Sulfur dioxides, Aerosols, Stratosphere, Atmospheric temperature, Condensation nuclei, Atmospheric models
What is the function of the skin of polar bear?
to keep the polar bear skin warm
What characteristics phospholipids is important to their function?
they have a polar head and non-polar tails
What is the function of the nuclei?
conscious awareness of balance; positon of the head in space
Do hydra have a nucleus?
Yes, hydra have nuclei in their cells. These nuclei contain the genetic material of the organism and are essential for cell function and replication.
What is the function of the commissurs?
to connect the habenular nuclei of the two sides of the epithalamus together.
How do animal and plant cells function?
Animal and plant cells are controlled by their nuclei.
