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

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

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

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.

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.

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. Gloriosa Ananas

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 Science, grade 4 Olga Volnycheva
