These are the densely stained reticular stuctures present near the nucleus, consisting of many flat, disc shaped cistemae of `0.5 - 1.0 mu m` diameter. These are

A

chloroplasts

B

endoplasmic reticulum

C

mitochondria

D

Golgi apparatus

Text Solution

Verified by Experts

The correct Answer is:
D

Camillo Golgi discovered the Golgi apparatus as reticular structure. Typically, it is `0.5 - 1.0 mu m` in diameter but its shape and size dependes upon the physiological state of the cell.

Go through the following statements : (i) Lysosomes contain hydrolytic enzymes which are optimally active at the alka line pH. (ii) A number of proteins synthesised by ribosomes on the endoplasmic reticulum are modified in the cisternae of the Golgi apparatus before they are released from its cis face.

A glass slab consists of thin uniform layers of progressively decreasing refractive indices refractive index such that the refractive index of any layer is mu-mDeltamu . Here mu and Deltamu denotes the refractive index of 0th layer and the difference in refractive index betweeen any two consecutive layers, resepctively. The integer m=0,1,2,3 ... denotes the number of the suscessive layers. A ray of light from the 0th layers enters the 1st layer at an angle of incidence of 30^(@) . After undergoing the mth refraction, the ray emerges paralllel to the interaface. If mu=1.5 and Deltamu=0.15 , then the value of m is
