If a plant is living in a cold environment, which physiological change would help the most with the cool temperatures?
Novosadov [1.4K]

The plant species that live in the colder environment have some adaptations that makes them survive in that conditions

These plants have a well developed vascular system due to which they have the ability to trap every inch of sunlight available for the process of photosynthesis.

Some of the plants shed their leaves and stay in dormant conditions.

Evergreen trees have thick waxy coating that prevents the loss of water.

The plants that grow in arctic regions are small and they grow close to the ground in a specific shape that helps them to shed snow from them.
