Cell Biology and Structure

Nucleus is the most vital organelle for the survival of cell. It controls and coordinates various activities of a cell.

When cell is old or injured, lysosomes rapidly destroy organelles. In case, its own cell is ruptured, it bursts out releasing its hydrolytic enzymes in the cells, thereby digesting the damaged cell. Therefore, it is called as the sucidial bag of the cell.

Vacuoles store various materials like starch, amino acids, water, nitrogenous waste, etc.

Vacuoles are covered by tonoplast and they store water, food material and waste products in a cell.

Endoplasmic reticulum serves as a channel for transport of materials between various regions of cytoplasm.

 Skin tissues have highest rate of regeneration as it undergoes wear and tear on regular basis.

The receptor is the right answer as it reserves the chemical signals externally from the calls.

Secretory organelles, which secrete enzymes to digest wood. The Protists inside the termites are Trichoflagellates, which secrete a digestive enzyme, cellulose, to digest cellulose. When these enzymes are lost, the termites can not digest wood.

This is a technique that divides a cell into multiple smaller cells to increase the number of subscribers.

These are organelles which contain digestive hydrolytic enzymes.

These are the sites of protein synthesis where the codon of mRNA is read by the anti codon of t RNA

It is the site where mRNA synthesise over nuclear chromosomal DNA.

These organelles are primarily concerned with beta oxidation of fatty acids and thus metabolises them.

These form the small vesicles that form the plant in the end of the telophase for the division of cytoplasm.

These are the membranous structures which have thalakoid having fret channels.
