Nucleus
1. What is the nucleus?
Answer:
All genetic information and other instructions necessary for the cellular functions of a cell are present in the double membrane organelle known as the nucleus. It is one of the biggest organelles and is only present in eukaryotic cells.
2. Nucleus is discovered by?
Answer:
Robert Brown discovered the nucleus in 1831.
3. Describe some functions of the nucleus.
Answer:
The nucleus serves two main purposes:
- It is in charge of keeping the DNA or other genetic material within the cell.
- It is in charge of organizing a variety of crucial cellular processes, including the synthesis of proteins, cell division, growth, and a number of other crucial operations.
4. What are the main parts of the nucleus?
Answer:
The main parts of the nucleus are; the nuclear membrane, genetic material, nucleolus, and nucleoplasm.
5. Define the structure of the nucleus.
Answer:
The general structure of a nucleus is spherical-shaped with double membrane having nuclear pores in the membrane.
Nucleus: Structure and Function
The nucleus (plural: nuclei) is a double-membraned organelle that is found only in eukaryotic cells. The name nucleus comes from a Latin term that means “nut kernel.” The nucleus was discovered by Robert Brown in 1831. It is the first cell organelle that was discovered.
The nucleus is responsible for containing the genetic material that holds the key to regulating all sorts of cellular activities. The presence and absence of the nucleus is one of the important characteristics that differentiate between the two main types of cells.
