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.

Answer : 4. "Insect"
Explanation :

Fragrant flowers attract pollinators like bees, butterflies, and birds with their pleasant scent. These pollinators visit the flowers to feed on nectar or collect pollen. During their visits, they unintentionally transfer pollen from one flower to another, facilitating pollination. This process enables the plant to reproduce and produce seeds. Different plants rely on specific pollinators, ensuring their reproductive success and genetic diversity within the ecosystem.
