1. Thirst for Life

2. Guess: Why Are We Here?
We will help you understand how plants depend on water

3. Why Do Plants Need Water?
Plants like all living creatures need water to survive
Water is a basic for all plant life

4. Types of Plants Depending on Water
Underwater Plants Location: seas, oceans.
Land Plants
Location: garden, rainforest, forest, desert, mountains
Water Plants
Location: ponds, lakes, rivers
All plants need water
Some plants need more water than others

5. Desert Plants Adaptation
Desert plants have adapted to the extremes of heat with little amount of water
They often have few or no leaves, which reduces transpiration.
Cacti usually have special means of storing and conserving water.
Some plants like desert irises have adapted to arid environments by growing extremely long roots, allowing them to acquire moisture at or near the water table.

6. Mountain Plants Adaptation
Labrador tea
The mountain environment is very harsh for plant to grow in.
They have a wide rot system in order to gather more water.
The flowers usually have very tough leaves and are waxy to prevent drying out.
The fuzzy underside of Labrador tea combs water droplets from clouds and acts like a sponge to keep the leaf surface moist. 
Mountain cranberry demonstrates another adaptation: a waxy cuticle that covers leaf surfaces and seals in moisture.

7. Rainforest Plants Adaptaion
Erythrina
The tropical rainforest flowers naturally grow in places with rainy, humid and warm climates.
Rainforest plants have made many adaptations to their environment.
Many plants have drip tips and grooved leaves, and some leaves have oily coatings to shed water.

Ananas

8. Water and Underwater Plants Adaptation
Water and underwater plants have adapted to living in or on aquatic environments.
They have smaller roots that water can go directly into leaves.
Surface plants like water lily have flat leaves for floatation
