Question

ribosomes not attached to the membrane of A- RER B- SER C- protoplasm D- lysosome​

Answer 1

Answer:

Unlike other organelles, ribosomes are not surrounded by a membrane. Each ribosome has two parts, a large and a small subunit, as shown in Figure below. The subunits are attached to one another. Ribosomes can be found alone or in groups within the cytoplasm

Answer 2

Answer:

Ribosomes are different from other organelles because they have no membrane around them that separates them from other organelles, they consist of two subunits, and when they are producing certain proteins they can become membrane bound to the endoplasmic reticulum, but they can also be free floating while performing function.
