Question

Plasmasol or sol part of the cytosol is known as
(a) Hyalomere
(b) Hyaloplasm
(c) Endoplasm
(d) Both B and C

Answer 1

A cytoplasm is divisible into three parts, among which cytosol is its fluid part and made up of $90\%$ water. Some chemicals are present as a true solution while others form a colloidal solution. This results in the appearance of two phases in the cytosol.

Complete step by step answer:
The cells of living organisms consist of protoplasm, which is bounded by a cell membrane. The protoplasm is represented by the cytoplasm and the nucleus. Cytosol or hyaloplasm is the fluid part of the cytoplasm that may exist in two states- sol and gel. The two are respectively called plasmasol and plasmagel. The plasmagel is usually present beneath the cell membrane and thus is often referred to as ectoplasm. Plasmasol is internal and is also referred to as endoplasm.
- Many membranes bound and non-membrane bound cell organelles are suspended in the cell membrane.
- Membrane- bound cell organelles include the endoplasmic reticulum, Golgi complex, Mitochondria, chloroplasts, and lysosomes.
- Non- membrane bound cell organelles include ribosomes, centrosomes, microbodies, microtubules, and microfilaments.
- Cytoplasm also includes certain cell inclusions. They may function as storage bodies of starch, fats and oils, and proteins. These inclusions may also store temporary secretory products like enzymes, hormones, pigments, alkaloids, resins, and gums. They also store excretory products like inorganic salts, latex, tannins, and essential oils.
So, the correct answer is ‘(d) Both B and C.’

Note:
- Cytoplasm performs a range of functions like acting as a mediator to exchange materials between the unconnected cell organelles. They do so by cytoplasmic streaming.
- All the essential metabolic reactions occur in the matrix of cytoplasm like glycolysis, anaerobic respiration, etc.
- As the cytoplasmic matrix is always in motion, it helps in the distribution of various materials uniformly to all the corners of the cell.
