Given below are two columns:
Column I lists the names of scientists and Column II lists the discoveries made by them towards understanding photosynthesis in plants.
Match the scientists with the corresponding discoveries and choose the correct code.

Column I	Column II
A. J.B. Van Helmont	{i}Starch is the first visible product of photosynthesis
B. Stephen Hales	{ii}Water of soil contributes to the growth of plants
C. Engelmann	{iii}Green plants get nourishment through their leaves from  air and sunlight
D. Sachs	{iv}Action spectrum of photosynthesis

Correct option is A

Correct Answer: (a)

Explanation:
The correct matches are:

A. J.B. Van Helmont → {ii}Water of soil contributes to the growth of plants.

B. Stephen Hales → {iii}Green plants get nourishment through leaves from air and sunlight.

C. Engelmann → {iv}Action spectrum of photosynthesis.

D. Sachs → {i}Starch is the first visible product of photosynthesis.

Information Booster:

-J.B. Van Helmont (1648): Through his willow tree experiment, showed that plant mass increase comes from water, not soil.

-Stephen Hales (1727): Father of plant physiology — demonstrated plants use air and sunlight.

-Engelmann (1882): Used algae and bacteria to show oxygen evolution linked to red and blue light — discovered action spectrum.

-Julius von Sachs (1864): Showed starch formation as evidence of photosynthesis.

These discoveries collectively formed the foundation for modern photosynthesis research.
