adapt
One way that plants adapt to the dry desert is by developing deep root systems.
Plants in the Desert have adaptations that allow them
to live in the dry salty conditions.
Most plant species are not adaptable to a desert environment.
v., to change to fit a situation or
environment
determine
v., to decide
dilute
v., to make weaker by mixing with water
diverse
The diverse ways that plants adapt to desert conditions makes a fascinating study.
Change in climate can result in species diversification.
As climate changes, plant species in an area may diversify if conditions improve.
adj., varied, of many kinds
evaporation
n., the change from liquid to gas; loss
of water to the air

K. n., wetness or water
occupy

Desert plants grow resiliently in the heat.
adj .. tough, able to endure difficult
conditions
sparse
Sparse rainfall and violent sandstorms make it one of the most extreme environments on Earth.
adj., small in numbers or amount
stressor
The plants’ principal defense against these environmental stressors consists of drawing in as
much water as possible while minimizing moisture loss.
The main stressor in a desert is lack of rain.
Heat and drought both stress plants.
Certain plants thrive in the desert despite the stressful conditions.
A long period of dryness causes a lot of stress to plants.
n., something that causes great
difficulties
swing
Sparse rainfall,
daily temperature swings of up to 20°C (68°F), and violent sandstorms make it one of the most extreme environments on Earth.
After a rainstorm in the desert, there is a noticeable swing back to life.
The swing of the branches in the breeze made a creaking noise.
n., a sudden or big change
noun. back-and-forth movement
noun. a hanging seat that moves back and forth
The children played on the swing all afternoon.
thrive
diverse plant forms not only have adapted to
the harsh conditions but actually thrive there.
v., to grow well.
transitional
transitional areas between the open desert and oases on the desert fringe support diverse plant forms that not only have adapted to the harsh conditions but actually thrive there.
adj., relating to change from one type
to another
violent
The violence of sandstorms keeps many plants from thriving in the desert.
Violent winds tear up many plants or cover them with sand
