Question

How many of the cell organelles have no membrane in a eukaryotic plant cell? Ribosome, Chloroplast, Mitochondria, Endoplasmic Reticulum, Golgi bodies.

Answer 1

A small organ-like structure present inside the cell is called a cell organelle. It has a particular structural makeup and performs a specific function. Depending upon the presence or absence of membrane, cell organelles can be classified into three categories, namely:

(a) Without membrane:- Some cell organelles like ribosomes are not bounded by any kinds of membranes.

(b) Single membrane bound:- Some organelles are bound by a single membrane. For example, golgi complex, endoplasmic reticulum etc.

(c) Double membrane bound:- Cell organelles like mitochondria and chloroplast are double membrane bound organelles.
