Answer:
An aqueous solution of carbohydrates, proteins , lipids, nucleic acids and inorganic salts surrounded by a cell membrane is called as cytoplasm.
The cytoplasm has three main components:
Cytosol:
It includes 70% of the total cell composition. Water is the main composition of the cytosol. It dissolves in it various inorganic and organic salts in it which bears ionic charge in them and carry out chemical reactions necessary for cellular metabolism. It contents macromolecules like proteins and lipids. Other than lipids all the macromolecules are dissolved in the water based on their polarity and can be used as a storage reservior for energy.
Organelles:
Cytoplasm contained within it many organelles like mitochondria, golgi apparatus, ribosomes, plastids, lysosomes, vacuole. Organelles like ribosome and mitochondria produces nucleic acids DNA and RNA. These organelles synthesize carbohydrates, proteins, nucleic acids, enzymes, non-organic salts.
Cytoplasmic inclusions:
These are the tiny particles suspended in the cytosol. Example include lipid droplets these are the spherical droplets made up of lipids and proteins are present in both prokaryotes and eukaryotes as a medium for storing lipids like fatty acids and sterols. These particles are chief components for adipocytes, the fat storing cells.
