The outermost limiting layer of mycoplasma is made up of:
1 Cell wall
2 Cell membrane
3 Mucilaginous sheath
4 Slime layer
Explanation:
B Mycoplasma is a genus of the kingdom monera and smallest bacteria. Its outer limiting layer is formed of cell membrane. They do not have cell wall around the cell membrane So, their cell lack a specific shape. In the absence of a cell wall, they are found to be resistant to many antibiotics like penicillium. - Plants and cyanobacteria show the presence of mucilaginous sheath which made up of thick gluey substance called mucilage. - Slime layer is loosely associated glycoprotein layer which is present outside the cell wall.

In which, mitosis does not occur?
1 Green algae
2 Fungi
3 Bacteria
4 higher plants
Explanation:
C Mitosis or mitotic division is meant for multiplication of cells. Mitosis generally takes place in vegetative or somatic cells. It creates two indentical daughter cells from one mother cell. Cell must have nucleus to undergo mitosis. A fertilized egg undergoes number of mitotic division to from zygote In plants mitosis occurs in the meristematic cell mitosis does not occurs in bacterial cell as bacterial cell does not have a nucleus.

In prokaryotes the Glycocalyx when it is thick is called
1 Slime layer
2 Mesosome
3 Capsule
4 Cell wall
Explanation:
C In prokaryotes, when the glycocalyx is thick and thick and well- organized it is called a capsule. The capsule is a protective layer outside the cell wall, and it helps the bacterium evade the host immune system and aids in attachment to surfaces. On the other hand, a thin and unorganized glycocalyx is known as a slime layer. Mesosomes are imagination of the cell membrane and are not related to the glycokalyx.

Extension of plasma membrane in prokaryotic cell is
1 mesosome
2 hapnoid
3 ribosome
4 none of these
Explanation:
A Mesosome or chondrioid are formed due to invagination of the plasma membrane of bacteria serve as the respiratory centre. Prokaryotic cells are devoid of membrane - bound organelles like the nucleus, mitochondria; ER etc Mesosomes are more prevalent in gram +ve bacteria and they are rich in respiratory enzyme of prokaryotic cell. The ribosome is the nonmembrane bound organelle hence is present in a prokaryotic cell but it is not formed due to the extension of the plasma membrane.

Select the wrong statement of bacterial cell
1 Mesosome is formed by the extensions of plasma membrane into the cell.
2 The pili are elongated tubular structures made up of a protein.
3 Flagellum is composed of filament, hook and basal body.
4 Ribosomes are about \(30 \mathrm{~nm}\) by \(50 \mathrm{~nm}\) in size.
5 The fimbriae are small bristle like fibres sprouting out of the cell.
Explanation:
D Fimbriae are finger like projections on the ends of fallopian tubes closest to ovaries. Mesosome is formed by extensions of plasma membrane into the cell. The pili are elongated tubular structure. Flagellum is composed of filament, hook and basal body.Eukaryotic Cell
