Answer 1

Answer:

1) Nucleus

functions :

*contains chromosome , dna, ..

*plays a central role in cellular reproduction

2)away from the cell

3) Animal cell

functions :

*cell wall is present only in plant cell , it provides the turgidity and rigidity to the cell and protects the cell

4) to form chromosomes ,

main components : dna

5) it is fluid content inside the plasma membrane , it contains many specialised cell organelles , each of these organs performs a specific function for the cell

6) endocytosis : the flexibility of the cell membrane alsoenables the cell to engulf in food and othermaterial from its external environment. Suchprocesses are known as endocytosis. Amoebaacquires its food through such processes.
