Mycoplasmas differs from other bacteria in their
1 DNA
2 RNA
3 Cell wall
4 Nutrition
Explanation:
C Mycoplasmas are unique among bacteria because they lack cell wall. Instead of having a rigid peptidoglycan cell wall like most bacteria, they have flexible cell membrane that contains sterols, which provide stability to the cell.

Which are the longest cells in the body of man?
1 Muscle cells of legs
2 Bone cells
3 Nerve cells
4 None of the above
Explanation:
C The longest cell in the human body are nerve cells, also known as neurons. Neurons are the building blocks of the nervous system and are responsible for transmitting information throughout the body.

Which is correct about cell theory in view of current status of our knowledge about cell structure?
1 It needs modification due to discovery of sub cellular structures like chloroplasts and mitochondria.
2 Modified cell theory means that all living being are composed of cells capable of reproducing.
3 Cell theory does not hold good because all living beings (e.g., viruses) do not have cellular organisation.
4 Cell theory means that all living objects consists of cells whether or not capable of reproducing.
Explanation:
C Cell theory does not hold good because all living being do not have cellular organization. This statement is correct about cell theory in view of current status of our knowledge about cell structure. The cell is the basic unit of structure and organization in organisms.

The 'Cell theory" states that
1 all cells have nuclei
2 cells are the fundamental structural matter of plants and animals
3 all cells are living
4 cells reproduce by mitosis and meiosis
Explanation:
B Cell theory was given by M. Schleiden (Botanist) and Schwann (Zoologist) (1839) both were German. According to cell theory cell is the structural and functional unit of life, all cells are similar in their chemical composition and metabolism.
