Question

how do tropisms help plants survive? (1 point)
plants limit their needs in harsh conditions.
plants grow toward things they need.
plants create their own food using chlorophyll.
plants grow together with other plants.

Explanation:

Tropisms are directional growth responses in plants to external stimuli like light, water, or gravity. This growth allows plants to move toward resources essential for survival, such as sunlight for photosynthesis or water from soil. The other options do not describe the survival function of tropisms: limiting needs is not related to tropisms, creating food via chlorophyll is photosynthesis, and growing with other plants is not a tropism-related survival mechanism.

Answer:

Plants grow toward things they need.
