NATURE AND OCCURRENCE -

-Most cellular organelles such as mitochondria, Chloroplast, lysosome, peroxisomes, golgi apparatus, nucleus and endoplasmic recticulum, are all enclosed by the unit membrane.

-The cell surface membrane or plasma membrane is the outer covering of each cell.

-It is present in cells of plant, animals, and microorganisms.

STRUCTURES -

-Plasma membrane is a living thin, delicate, elastic,, selective permeable membrane.

FUNCTION -

-Plasma membrane permits the entry and exit of some material in the cells.

AND YOUR ANSWER IS-

-The plasma membrane allows some molecular spaces to enter and excludes others. It is therefore, referred as a(n) semi permeable membrane

Answer 2

The 'plasma membrane' allows some 'molecular species' to 'enter and excludes others'. It is therefore referred to as a semi-permeable membrane.  

Explanation:

• The 'plasma membrane' is the 'outer covering of the cell'. It can be seen in the 'cells of plants', 'animals' and 'microorganisms'.
• This is a thin, delicate, elastic and semi permeable membrane. Plasma membrane allows entry and exit of some material by its layer.
• Most of the organelles like mitochondria, Golgi apparatus, chloroplast, lysosome are enclosed by this membrane. This membrane allows some material to enter the cells and restrict some material to exit from the cell.
