Plants grow toward things they need.

Explanation:

Tropisms help plants to survive by ensuring that they grow towards what they need.

Tropism is defined as the growth of plants or their organs towards or away from external stimuli such as light, moisture, gravity, etc. This type of growth ensures that plants are able to grow towards what they need and away from what they do not need.

For example, the stems of plants generally grow towards light because light is necessary for photosynthesis. Similarly, the roots of plants always grow downward as a positive response to gravity in order to ensure that the plant is firmly supported in the soil. The roots of plants will also grow towards moisture because of the essentiality of water for plant's metabolic processes.
