Read the following statement and give correct answer regarding bacterial cell (a) Glycocalyx is the outermost envelop in bacteria (b) The glycocalyx could be a loose sheath called capsule (c) The glycocalyx may be the thick and tough called slime layer
1 a correct
2 a, b correct
3 a, c correct
4 b correct
Explanation:
Glycocalyx differs in composition and thickness among different bacteria. It could be a loose sheath called the slime layer in some, while in others it may be thick and tough, called the capsule.

Which of the following is not includes in endomembrane system : (a) Golgi apparatus (b) Endoplasmic Reticulum (c) Mitochondria (d) Lysosome
1 a only
2 a and d only
3 c only
4 d only
Explanation:
The endomembrane system include endoplasmic reticulum (ER), golgi complex, lysosomes and vacuoles. Since the functions of the mitochondria, chloroplast and peroxisomes are not coordinated with the above components, these are not considered as part of the endomembrane system.

The characteristic feature of diplotene stage of meiosis is recognized by :
1 Dissolution of synaptonemal complex
2 Homologous chromosomes of bivalent start separate from each other
3 X-shaped structure chiasmata formed
4 All of the above
Explanation:
The beginning of diplotene is recognised by the dissolution of the synaptonemal complex and the tendency of the recombined homologous chromosomes of the bivalents to separate from each other except at the sites of crossovers. These \(\mathrm{X}\)-shaped structures, are called chiasmata.
