Which of the following sentences is correct?
1 Cells of all living organisms have a nucleus.
2 Both animal and plant cells have a welldefined cell wall.
3 In prokaryotes there are no membrane bound cell organelles.
4 Cells are formed de novo from abiotic materials.
Explanation:
Prokaryotes are single celled organisms which lack membrane bound cell organelles. They do not possess well organised nucleus as present in eukaryotic organisms, rather DNA is naked, lies freely in cytoplasm, and is known as nucleoid. According to cell theory, new cells develop by division of pre-existing cells. Cell wall is outer, rigid, protective covering present in plant cells but absent in animal cells.

Which of the following is correct in plant cell?
1 Absence of cell membrane
2 Bigger vacuole with rigid cell wall
3 Centrioles and centrosome are present
4 DNA is absent
Explanation:
Plant and animal cells are different as the former, possesses cell walls. Plasmids and large vacuole are absent in animal cells. Animal cells, have centrioles which are absent in almost all plant cells.
Protoplast is a part of plant cell which lies within the cell wall and can be plasmolysed and which can be isolated by removing the cell wall by mechanical or enzymatic procedure.
