Answer 1

Explanation:

Basically,there are no differences between heliotropism and phototropism.

- Heliotropism is a movement of plant body where the environmental stimulation for the movement is the sunlight.

- And, phototropism is a movement of plant body where the environmental simulation for the movement is light source.

- Now,the sunlight is also a type of light source.

- That's why in late 19th century the heliotropism was renamed into phototropism. And,in the present time heliotropism and phototropism are the same thing.

Answer 2

Answer:

Various plants show heliotropism the most obvious being the sunflower that racks the suns path during the day. Osteospermum, scarlet pimpernel and other plants only fully open their flowers in response to bright sunlight. Phototropism is a more general response to light by various parts of a plant.....PLEASE FOLLOW ME FOR THE CORRECT ANSWER
