​Plant Hormones and Environmental Stimuli

By: Tanay Bollam

Plant hormones are signal molecules made up of chemical compounds that control all aspects of a plant's ability to grow.​

Examples of Tropisms will be shown on the next slide

Some text here about the topic of discussion

This tropism is the process of roots growing towardthe pull of gravity.

​​Gravitropism

​

This tropism is the tilting of a plant towards the light source.

​​Phototropism

​

​This tropism is the turning/bending of a plant in response to a touch stimulus.

​​Thigmotropism

This tropism is when a plant's roots grow towards water.

​​Hydrotropism

Multiple Choice
