Detailed explanation-1: -Drip Tips The leaves of forest trees have adapted to cope with exceptionally high rainfall. Many tropical rainforest leaves have a drip tip. It is thought that these drip tips enable rain drops to run off quickly. Plants need to shed water to avoid growth of fungus and bacteria in the warm, wet tropical rainforest.

Detailed explanation-2: -Shade plants often have thin leaves with large surface areas. Thus they are anatomically adapted to be efficient at photosynthesis in low light.

Detailed explanation-3: -Rainforest plants have shallow root systems which enable them to obtain moisture and tap into the rich supply of nutrients available from rotting plant and animal materials in the upper soil layer. The leaves of rainforest trees have special adaptations and are noticeably different from eucalyptus leaves.

Detailed explanation-4: -The thick layer of dense leaves, called the canopy, blocks much of the sunlight from reaching the forest floor. Plants below the canopy have adaptations for photosynthesizing in low light.
