Question
Plants growing towards a source of light exhibit _____________.
- Positive phototropism
- Negative phototropism
- Positive geotropism
- Negative geotropism
Hint:
Another word for light is photon.
The correct answer is: Positive phototropism
The correct option is a) positive phototropism.
Differences in cell elongation exhibited by plant organs in response to phototropic, or directed blue light, are a means of optimizing photosynthetic light uptake in plant aerial parts and water and nutrient uptake in roots to the plants.
Positive phototropism is to grow towards the light source. Negative phototropism is growing away from light. Shoots, or parts of above-ground plants, usually exhibit positive phototropism. That is, it is tilted towards the light.

Plants are not sensitive to heat.
The statement is false.
Heat stress is often defined as a sufficiently high temperature for a sufficient period of time to cause irreversible damage to plant function and development. In addition, high temperatures increase the rate of reproductive development and shorten the time during which photosynthesis contributes to fruit and seed production. Plants can be harmed in many ways by hot day and night temperatures, hot air temperatures, and high soil temperatures. Pea plants can even die due to high temperature.
