Plants

In the Water

Adaptations

Plants must be flexible to be able to move with the water currents.

The roots are only needed as an anchor and not for absorption of water and nutrients. With that being said, water, and nutrients are absorbed through the leaves directly from the water.

Some plants have air spaces in their stems to help hold up the plants above water.

Some plants will produce seeds that will float.

Floating plants chlorophyll is restricted to upper surface of the leaves and the upper surface is waxy to repel water.

Plants in the Desert

The desert is very dry and hot. Deserts average rainfall is less than 10 inches per year.

There is a lot of direct sunlight shining on the plants. The soil is sandy and rocky. The plants usually die due to the strong winds.

Due to the conditions of the desert, the plants are unique. Desert plants will have long root systems that will spread out wide or go deep into the ground to get water. Some plants will store water in their stems or leaves. Some plants have no leaves or small season leaves that will only grow after it rains. The lack of leaves isn't that bad because it reduces the water lost during photosynthesis.
Some leaves on plants will have hair that will shade the plant and reduce water loss. Some plants will have spines to discourage animals not to eat them for nutrients or water. Plants will grow slowly because it requires less energy and they won't have to make that much food and results them in not using that much water.
