Chapter 4: Q.9 (page 124)

Which of the following is surrounded by two

phospholipid bilayers?

a. the ribosomes

b. the vesicles

c. the cytoplasm

d. the nucleoplasm

Short Answer

Expert verified

The correct answer is option d. the Nucleoplasm

Step by step solution

01

Explanation

Ribosomes are non-membrane-bound organelles as they lack an outer membrane.

A vesicle is a self-contained structure that is surrounded and encased by a single lipid bilayer membrane.

The cytoplasm

is enclosed by the cytoplasmic membrane is made up of a semipermeable lipid bilayer.

Nucleoplasm is a gel-like substance within a cell membrane, it consists of two phospholipid bilayers; inner membrane and outer membrane.

02

Final Answer

Nucleoplasm has a phospholipid bilayer which works as a barrier, preventing chemicals and ions from entering and leaving the cell.
