Test: Cell- The Fundamental Unit Of Life- 1

The endoplasmic reticulum functions both as a passageway for intracellular transport and as a manufacturing surface.

 Each cell is bounded by an extremely delicate, thin elastic living membrane, called the plasma membrane. The plasma membrane is made up of two layers of lipid (fat) molecules with protein molecules which is sand witched between lipid layer.

the inner membrane has more curls and turns compared to outer membrane , you can also take reference of brain(it has many curls and turns(neurons) and many experts say that our brains' neurons are much longer in length of our inner intestine(inner intestine measures 7 meters)).

Beside nucleus, mitochondria is another cell organelle which has its own self-replicating DNA. It is known as mitochondrial DNA and thus called as a semi-autonomous organelle.

The function of smooth endoplasmic reticulum is to detoxify the poison and drugs present in our body.

Ribosomes are majorly involved in protein synthesis, as these are the sites of protein synthesis and enzymes. It also synthesizes amino acids which polymerize to form proteins.

So option C is correct.

Vacoules store excess food of cell, when it is emergency they release them and in plant cells the vacoules are larger in size(compared to animal cells) because plants can not move

Vacuole and lysosome are covered by a single membrane.

Cellulose is present in cell walls of all plants, and some bacteria, and is the most abundant natural polysaccharide on earth.

The site of energy generation is mitochondria. The endoplasmic reticulum is involved in the transportation of protein and other material as well as the site for some biochemical activities.
