Question

The three types of plastids were named by
A. Andreas Schimper
B. Camillo Golgi
C. Robert Brown
D. Fontana

Answer 1

Hint: Now this is a very factual question whether it is known or not known. Plastids are organelles that are found in plant cells only and some unicellular organisms. It is divided into several types depending on the nature of pigments it contains.

Complete answer-
We will solve this question by studying about each scientist a little bit.
The three types of plastids known are –
Chloroplast – It contains chlorophyll pigments, which performs the function of trapping light energy required for the formation of ATP and NADPH. Both these molecules are required for fixing carbon-di-oxide.
Chromoplast – It contains pigments other than the chlorophyll like carotenoids, carotene and xanthophyll which are responsible for yellow, red or red color in plants.
Leucoplast – It acts as storage organelle and is classified on the basis of the material used e.g. amyloplast stores carbohydrates in the form of starch, aleuroplast or proteinoplast store proteins whereas the elaioplasts store oils or fats. The names of these plastids were given by Andreas Schimper.
Robert Brown discovered the nucleus in 1831. The nucleus is the clearest and principal organelle of eukaryotic cells as it controls most of the activities of the cell.
Camillo Golgi, as the name provides its hint, discovered the Golgi apparatus. It is a membranous organelle composed of flattened sac like cisternae stacked on one another.
Fontana recognized the nucleolus in 1874. It is a spherical structure, which is not separated from the rest of the nucleoplasm by a membrane.

From the above discovered facts about scientists now we know that option (A) Andreas Schimper is the right answer.

Note:
As plastids contain their own genetic material and protein synthesis machinery, they are capable of multiplication by fission like processes.
While most eukaryotic cells possess Golgi apparatus, many fungi and ciliated protozoans lack well-formed Golgi bodies.
