What is it called when a tree grown slanted but straightens as it grow?

This phenomenon is known as "phototropism." It occurs when a tree or plant grows at an angle due to light exposure but gradually straightens as it continues to grow toward the light source. The tree's cells on the darker side elongate more than those on the lighted side, allowing it to adjust its orientation. This adaptive growth helps the tree optimize its access to sunlight for photosynthesis.
