What is studied under Palynology?
A. Germination of pollen grains
B. Development of pollen grains
C. Morphology of pollen grains
D. Storage and arrangement of pollen grains

Hint: Palynology is the study of pollen, spores and microscopic plankton organisms in both living and fossil forms. Palynology is used for extensive research on the morphological traits of the pollen grains and it’s adaptability to change according to the varying environment.

Complete answer:
Pollen grains have a number of morphological and ultrastructural features and the study of these pollen grains is imperative.
Pollen is very specific to each plant and it is very resistant to getting damaged.
Pollen has the ability to survive for many years due to its chemically stable structure.
Pollen are identified based on their morphological structures.
The study of pollen grains and its morphological structures and its features is called Palynology.
The study of these pollen grains allows us to identify a particular plant taxon.

Therefore, the answer to the question is option (C).

Note:
Palynology is used in various fields of botany. It can be used to reconstruct past vegetation and marine and freshwater phytoplankton communities.
It can be used to give an opinion or form a conclusion in the environment and paleoclimate conditions in an area of thousands or millions of years ago.
Palynology is used extensively for the research of climatic change that is keep changing day by day in today’s world.
The identity, density, and frequency of pollen grain at a particular stratigraphic level can give information as to the plant species present at that time and place.
Pollen spores are produced in large numbers and dispersed over large areas by wind and water, their fossils are recoverable in statistically significant assemblages in a wide variety of sedimentary rocks.
