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.
Poison ivies can grow as small plants, shrubs, or climbing vines. [4] They are commonly characterized by clusters of leaves, each containing three leaflets, [4] hence the common expression "leaves of three, let it be". [5] These leaves can vary between an elliptic to egg shape and will have either smooth, lobed, or toothed margins.

Houseplants which survive in conditions similar to a homeowner's living space will have a higher probability of survival. Tropical houseplants which grow under high thresholds of heat, for instance, will grow sun leaves which contain fewer chloroplasts. Plants which grow in the shade will grow shade leaves, containing more chloroplasts.
