Another way that plants alter their morphology to protect against stress is by changing the leaf orientation. [2] Plants can suffer from heat stress if the sun’s rays are too strong. Changing the orientation of their leaves in different directions (parallel or perpendicular) allows plants to reduce damage from intense light.

The leaves of plants experiencing root rot often yellow and die, and if allowed to continue, the condition can be fatal to the plant. To avoid root rot, it is best to only water plants when the soil becomes dry, and to put the plant in a well-drained pot. Using a dense potting media such as one dug up from outdoors can also cause root rot.
The following terms are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (that is, the leaf blade or 'lamina' is undivided) or compound (that is, the leaf blade is divided into two or more leaflets). [1] The edge of the leaf may be regular or irregular, and may be smooth or have hair, bristles, or ...

Most species of cacti have lost true leaves, retaining only spines, which are highly modified leaves. As well as defending against herbivores, spines help prevent water loss by reducing air flow close to the cactus and providing some shade.
