Answer:
2.The plastid involved in the process of photosynthesis is chloroplast. It contains chlorophyll pigment which plays an important role during the photosynthesis. It also gives green color to the leaves.

4.Chromatin is a complex of DNA, protein and RNA found in eukaryotic cells. ... During mitosis and meiosis, chromatin facilitates proper segregation of the chromosomes in anaphase; the characteristic shapes of chromosomes visible during this stage are the result of DNA being coiled into highly condensed chromatin.
5.White blood cells (WBCs):- In human blood, white blood cells or leukocytes have the ability to change their form or shape. This allows them to engulf germs and destroy them. They possess a nucleus and lack haemoglobin unlike RBCs.
