Non-membranous nucleoplasmic structures in the nucleus, are the sites for active synthesis of:

1.	protein	2.	mRNA
3.	rRNA	4.	tRNA

Match column I with column II.

Choose the right match from the options given below:

Which cell organelle principally performs the function of packaging materials, to be delivered either to the intra-cellular targets or secreted outside the cell?
1. Rough endoplasmic reticulum
2. Golgi apparatus
3. Smooth endoplasmic reticulum
4. Lysosomes

The diagram below is a diagrammatic representation showing

1. Section of a centriole
2. A cartwheel 9 + 0 structure of microtubular organisation
3. Internal structure of an eukaryotic flagella
4. Internal structure of a centrosome

Which organelle is extensive and continuous with the outer membrane of the nucleus?
1. Golgi complex
2. ER
3. Vacuole
4. Lysosome

Choose the incorrectly matched pair.

1. Contractile vacuole - Excretion.
2. SER - Steroidal hormones synthesis.
3. Xanthophyll - Fat soluble pigment.
4. Eukaryotic flagellum - Extension of basal body.

Which of the following statement are correct:-

1. Lysosome contain a hydrolytic enzyme which acts in pH= 5

2. Glycosylation complete in the Golgi body.

3. Mitochondria are stained with vital stain Janus green B.

4. All of the above. 

Smooth endoplasmic reticulum performs all the
functions, except
1. Production of glycoprotein.
2. Synthesis of lipid.
3. Synthesis of glycogen.
4. Synthesis of steroidal hormones

Mark the incorrect statement

The organelles formed by the process of packaging in the golgi apparatus is
1. Double membrane organelle.
2. Possess single circular DNA molecule
3. Rich in hydrolases
4. Able to occupy up to 90 percent volume of the cell
