Answєr :
Name dyes which is used to dye or colour the nucleus in the cell?
- Haematoxylin and eosin (H&E) staining
- Haematoxylin stains cell nuclei blue, while eosin stains cytoplasm, connective tissue and other extracellular substances pink or red. Eosin is strongly absorbed by red blood cells, colouring them bright red.
________________________________
Write structure of nucleus?
- The nucleus is a spherical-shaped organelle that is present in every eukaryotic cell. The Nucleus is the control centre of eukaryotic cells. It is also responsible for the coordination of genes and gene expression. The structure of the nucleus includes nuclear membrane, chromosomes, nucleoplasm, and nucleolus.
________________________________
What aap functions of poures in nucleus?
- Nuclear pores are tiny holes present in the nuclear membrane of the nucleus. ... They allow molecules such as RNA and proteins to move in both directions, between the nucleus and the cytoplasm.
________________________________
What our chromosomes?Also,write their functions ?
- The most important function of chromosomes is to carry the basic genetic material – DNA. DNA provides genetic information for various cellular functions. These functions are essential for growth, survival, and reproduction of the organisms. Histones and other proteins cover the Chromosomes.
________________________________
Write the full form of DNA and also,write its functions?
- The DNA full form is Deoxyribonucleic Acid. ... DNA's basic building blocks are nucleotides, containing a carbon-sugar group, a phosphate group, and a nitrogen base. The groups of sugar and phosphate bind the nucleotides together to form every DNA strand.
________________________________
What are functions of nucleus?
- 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.
________________________________
What are prokaryotic and Eukaryotics?
- A prokaryote, also spelled procaryote, any organism that lacks a distinct nucleus and other organelles due to the absence of internal membranes. Bacteria are among the best-known prokaryotic organisms. The lack of internal membranes in prokaryotes distinguishes them from eukaryotes. Some prokaryotes have flagella.
- A eukaryote, any cell or organism that possesses a clearly defined nucleus. ... The eukaryotic cell has a nuclear membrane that surrounds the nucleus, in which the well-defined chromosomes (bodies containing the hereditary material) are located.
________________________________
What is nucleoud?
- A nucleus is a membrane-bound organelle that contains the cell's chromosomes. Pores in the nuclear membrane allow for the passage of molecules in and out of the nucleus.
________________________________
What is cytoplasm and write their functions
- Cytoplasm is the fluid that fills cells and serves several important functions. Cytoplasm holds the internal components of cells in place and protects them from damage. Cytoplasm stores molecules used for cellular processes, as well as hosts many of these processes within the cell itself.

Why viruses are not included in living organisms?
- Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.
