Answer 2

A Crescograph can measure the growth in plants.

• The Crescograph was invented by Jagadish Chandra Bose.
• The instrument showed the movement and growth in the plants along with movement in small tissues and also the pulse beat of plants.
• The device had a gear set and smoked glass plate that noted the movement of the tip of a plant under a 1/10000 magnetic scale.
• The plate captured the plant 's reflection and was soaked in bromide, a toxin.
• The spot of light on the smoked board detected the plant's pulse. The spots became unstable as the plant began to take in the poison, thus, proving there is life in plants.
