1. Function of Cells
Scientists define seven functions that must be fulfilled by a living organism. These are:
A living thing must respond to changes in its environment.
A living thing must grow and develop across its lifespan.
A living thing must be able to reproduce, or make copies of itself.
A living thing must have metabolism.
A living thing must maintain homeostasis, or keep its internal environment the same regardless of outside changes.
A living thing must be made of cells.
A living thing must pass on traits to its offspring.
2. Nucleus function
It controls the heredity characteristics of an organism.
It is responsible for protein synthesis, cell division, growth and differentiation.
Stores heredity material in the form of deoxy-ribonucleic acid (DNA) strands.Also stores proteins and ribonucleic acid (RNA) in the nucleolus.
It is a site for transcription process in which messenger RNA (m RNA) are produced for protein synthesis.
Aids in exchange of DNA and RNA (heredity materials) between the nucleus and the rest of the cell.
Nucleolus produces ribosomes and are known as protein factories.
It also regulates the integrity of genes and gene expression.

1. main function of nucleus is to control gene expression and mediate the replication of the DNA during replication.
2. main function is to provide structure,support and protection for the cell.
please mark me as brainliest
