C. Plants create their own food using chlorophyll.
D. Plants limit their needs in harsh conditions.
B. Plants grow toward things they need.
Tropisms help plants survive by allowing them to respond to stimuli in their environment and grow in specific directions. For example, plants can exhibit phototropism by growing towards light to maximize their access to sunlight for photosynthesis. They can also exhibit gravitropism by growing roots towards gravity and shoots away from it, allowing them to anchor themselves and maximize their exposure to resources in the soil. These responses help plants find and utilize the resources they need for growth and survival.
