have an outer membrane as the delimiting structure of the cell. Inside each cell is a dense membrane bound structure called nucleus. This nucleus contains the chromosomes which in turn contain the genetic material, DNA. Cells that have membrane bound nuclei are called eukaryotic whereas cells that lack a membrane bound nucleus are prokaryotic.
Following are the important nucleus function: It contains the cell’s hereditary information and controls the cell’s growth and reproduction. The nucleus has been clearly explained as a membrane-bound structure that comprises the genetic material of a cell.
15 Ιαν 2021 · NUCLEUS Has a double layered covering called nuclear membrane. Nuclear membrane has pores which allow the transfer of material from inside the nucleus to its outside (cytoplasm). Contains chromosomes which are visible as rod-shaped structures only when the cell is about to divide. Chromosomes contain information for inheritance of features from ...
z illustrate the structure of plant and animal cells by drawing labelled diagrams; z describe the structure and functions of plasma membrane, cell wall, endoplasmic reticulum (ER), cilia, flagella, nucleus, ribosomes, mitochondria, chloroplasts, golgi body, peroxisome, glyoxysome and lysosome;
What is the function of the nucleus in a cell? Ans. The nucleus is the control center of the cell and has several essential functions. One of its primary roles is to store and protect the cell's genetic material, which is in the form of DNA.
31 Οκτ 2023 · The main function of the cell nucleus is to control gene expression and mediate the replication of DNA during the cell cycle. It controls the hereditary characteristics of an organism. The organelle is also responsible for protein synthesis, cell division, growth, and differentiation.
A nucleus diagram for Class 9 shows the nucleus of a cell. The nucleus is like the cell’s control center. It holds DNA, which tells the cell what to do. The diagram shows the nuclear membrane, which is like a protective shell around the nucleus. Inside, there’s nucleoplasm where the DNA lives.
