  1. Plants have different shaped leaves as they have coped to live in different environments. For example, evergreen trees and cactuses have lots of long, thin, needle-like leaves to reduce the loss of water in their habitats as it is extremely dry. Whereas, plants in wet countries have broader leaves to increase the amount of light energy captured. Plants that flower must also put energy into producing the flower so therefore have broad, but fewer, leaves to catch as much sunlight as possible, without investing too much energy into the leaves. Ground dwelling plants, such as those on the forest floor, have very broad leaves to soak up the little sunlight that actually makes it through the thick canopy.
