Question

24. Extra nuclear protoplasm is called a)prokaryote, b) cytoplasm, c)plastids, d) chloroplast​

Answer 1

Answer:

According to the older usage the extra-nuclear portion of the protoplast [the entire cell, excluding the cell wall] was called "protoplasm," but the nucleus also is composed of protoplasm, or living substance in its broader sense. ...

Answer 2

Answer:

cytoplasm

Explanation:

The protoplasm is used to denote the cytoplasm of the prokaryotes or the bacteria. But in case of eukaryotes we use the term cytoplasm rather than the protoplasm.

The main reason is protoplasm means the pre form of cytoplasm which means an ancient form of cytoplasm. The protoplasm is the part which contains the cytoplasm and the chromosome simultaneously. And this can be seen only in case of the prokaryotes, because they have no barrier between the cytoplasm and the nuclear materials.

so,

$protoplasm-nucleus=cytoplasm$

The option (a) prokaryote is not a correct answer

option (c) plastids is an organelle

option(d) chloroplast is also an organelle

so the answer will be (b) cytoplasm
