Desert Plant Adaptations

The desert is particularly dry. Rainfall averages to less than 10 inches a year, all at once. Strong winds, and loose sand that is nearly incapable of holding water dries out any plants in the extreme climates. So how do plants survive in the desert?

<>Plants called succulents store water in stems or leaves

<>Leaves are typically small or seasonal, growing after it rains, some plants don't have leaves and conduct photosynthesis through their green stems.

<>Long root systems.

<>Some plants have short life cycles to evade drought.

<>Some plants have leaves with hair on it help reduce water loss by shading the plant.

<>Plants like cacti have spines to stop animals from eating the plant for water.

<>They grow more slowly, because it requires less energy, and don't have to make as much food, and save water.

Tropical Rainforest

Tropical rain forests get a lot of rain; about 80 to 180 inches per year. The climate is typically hot and humid, though not much sunlight is able to penetrate the forest floor, due to how thick the forest itself is. Soil erosion, flooding, and growth of bacteria and fungi, are disadvantages to this much rain, therefore plants grow quickly to use up organic material from decomposed plants and animals. So how do plants survive in the rainforest?

<>Plants have drip tips, and waxy surfaces for the run off of water.

<>Stilt roots help hold up the plants in the soft soil, and other plants climb others to reach the sunlight.

<>Smooth bark also help in run off of water.

<>Plants have shallow roots so they can get nutrients from the top level of the soil.

<>Flowers are designed to attract pollinators because there is hardly any wind on the forest floor.
