Cell and Cell Division

Cell wall and cell membrane are both present in bacterial cells, while animal cells contain only cell membrane.

The dark spot-like structure that helps in making ribosomes is called nucleolus and it is present in the nucleus.

Bacterial cell and ostrich egg are the smallest and the largest cells, respectively.

The undefined region of the nucleus in prokaryotes is termed as nucleoid.

ATP is the energy currency of the cell. 

In anaphase stage, chromatids start moving towards the opposite poles, while the chromosomes are drawn to each side of the cell. The non-kinetochore spindle fibres push against each other, in a ratcheting action, that stretches the cell into an oval. 

The main function of golgi body is to store and dispatch the materials synthesised by ER.

The characteristic feature of meiosis is that the daughter cells have half the number of chromosomes as that of the parent cell (2n – n).

As plastids and cell wall are present only in plants, but not in animals and centrosomes are present in animal cells, so option 2 is correct.

Chloroplast is a double membranous organelle having an outer membrane as well as an inner membrane.
