Answer : 4. "protein"
Explanation :

Tissues are formed from the assemblage of cells and intercellular materials in various proportions in which one component predominates. In nervous tissue as an example, nerve cells predominate while in connective tissues such as Ligaments and Tendons, intercellular fibrous materials predominate.

Answer : 3. "chromoplast"
Explanation :

 Protein synthesis takes place in the cell on ribosomes. Ribosomes are cellular structures composed of RNA and proteins, and they are the sites where amino acids are linked together to form proteins, following the instructions encoded in messenger RNA (mRNA) molecules. This process, called translation, is a fundamental cellular mechanism essential for the synthesis of various proteins necessary for the functioning of the cell and the organism as a whole. Ribosomes can be found both in the cytoplasm of the cell and attached to the endoplasmic reticulum in eukaryotic cells.

Answer : 4. "from lichen"
Explanation :

Litmus is obtained from lichens, which are composite organisms formed from a symbiotic relationship between a fungus and an alga or cyanobacterium. Litmus is a water-soluble mixture of different dyes extracted from lichens, primarily Roccella tinctoria and Roccella fuciformis. It is commonly used as a pH indicator in laboratories to test the acidity or alkalinity of solutions.
