Answer:

$\huge\tt\underline{question}$

what are the main functions of each of the following components:

1)plasma membrane

2) mitochondria

3) nucleus

4) ribosomes

$\huge\tt\underline\red{answer}$

the functions of the following components are:

1)plasma membrane

• protective barrier
• regulate transport in and out of cell(selectively permeable)
• allow cell recognition
• provide anchoring sites of filaments of cytoskeleton

2) mitochondria

• production of ATP(energy)
• regulation of immunity
• calcium balance
• cell death and renewal(autophagy)
• stem cell regulation

3) nucleus

• controls all the cellular functions
• control the synthesis of structural proteins
• contains genetic nformation for reproduction, development and behaviour

4) ribosomes

• protein builders of the cell.
• travel alongs RNA and cannect amino acids into polypeptides.
• polyribosomes can make several polypeptides at the same time.
• protein synthesis
• intracellular digestion
• transport of protein outside of the cell

Answer 2

Answer:

A. plasma membrane

It seperates the content of the cell from its surrounding.

B. Mitochondria

Release of energy form pyruvic acid produced in the cytoplasm in the form of ATP and helps in the synthesis of respiratory enzymes.

C. Nucleus

controls all the cellular functions

D. Ribosomes

protein builders of the cell.

Protein synthesis.
