1 . (C) smooth endoplasmic reticulum

2. (a) rough endoplasmic reticulum

3. (b) neucleolus

5. (c) providing rigidity ..

6. (b) endocytosis

Answer 2

1st Answer

Option (c) Smooth endoplasmic reticulum is correct.

$\bigstar$ The endoplasmic reticulum which is free of ribosomes is known as smooth endoplasmic reticulum (SER). When it is observerd under the electron microscope it appears as smooth tubular structure. It plays a crucial role in detoxifying many poisons and drugs in a cell.

2nd Answer

Option (a) Rough endoplasmic reticulum is correct.

$\bigstar$ The endoplasmic reticulum bearing ribosomes on its surface is called Rough endoplasmic reticulum (RER). They provide site for proteins synthesis, because rough endoplasmic reticulum has ribosomes on its surface.

3rd Answer

Option (d) Nucleoid is correct.

$\bigstar$ The undefined nuclear region of prokaryotes are also known a Nucleoid.

4th Answer

Option (d) Golgi apparatus is correct.

$\bigstar$ Golgi body recieves the materials from endoplasmic reticulum. These materials are chemically modified by golgi body. They involved in forming complex sugars from simple sugars.

5th Answer

Option (d) Locomotion is correct.

$\bigstar$ The vacuole is the membrane bound space found in the cytoplasm. The vocuole is bounded by a single membrane they facilities the transport of a number of ions and other materials against concerntration gradient into the vacuole.

6th Answer

Option (b) Endocytosis is correct.

$\bigstar$ Endocytosis is the process of engulfing food particles from the exterior medium with the help of cell membrane. In Amoeba, the contractile vacuole is important for excretion. The food vacuoles are formed by engulfing the food particles.

7th Answer

Option (a) Bacteria is correct.

$\bigstar$ In Bacteria the glycocalyx and cell wall forms an outer covering for the plasma membrane together known as cell envelope. the viscous layer present outside to the cell wall is known as glycocalyx.
