Our planet has incredibly diverse environments that look like something out of a science fiction movie. From scorching deserts and rainforests, to cold tundras and rugged mountains, to mysterious wetlands, almost everywhere plants grow! How is this possible?<\/p>

Our planet is made up of about 70% water and 30% land. Of that land, about 31% is covered by forests, and if we add other types of vegetation (grasslands, shrubs, bushes, etc.), almost half of the ice-free land is home to plant life. Meanwhile, according to recent studies, 8 billion people live on only 7.6% of the earth’s surface. The plant kingdom has adapted much better than humans!<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

In deserts, where water is very scarce and valuable, cacti have evolved to have leaves transformed into spines (less surface area to lose water!) and succulent tissues that store reserves. In addition, their roots can extend several meters deep to reach water hidden beneath the sand.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Some orchids and bromeliads grow on other trees and have roots that absorb moisture from the air. To do this they have specialized roots, covered with a spongy tissue called velamen, which acts as a \u201csorbent\u201d to absorb water and nutrients directly from the air and rain.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Desert plants, such as certain cacti, use a trick called CAM photosynthesis. Instead of opening their tiny \u201cpores\u201d (stomata) during the day when the sun heats up and water evaporates, they open them at night! This reduces water loss by as much as 70-80% compared to other plants.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

In extremely nutrient-poor soils, some plants such as Venus flytrap or pitcher plants have decided to change the rules of the game: instead of absorbing nutrients from the soil, they capture insects. By decomposing their prey, they obtain the nitrogen and other minerals they need to grow.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

In coastal areas or in saline soils, where salt is a deadly enemy for most plants, there are halophytes.
