Plant Adaptations By: Desi Krueger
Trees in temperate deciduous forests have acquired thick bark so that they can protect their stems from cold winters.
One way that plants adapt to dry climates such as a desert is by having no leaves or seasonal leaves that only appear after it rains. This prevents moisture loss through the leaves.
Some plants in the tundra have dish-like flowers that focus their solar heat towards the center in order to retain more heat. They also follow the sun.
Desert plants have adapted to long root systems that either run deep or long in order to absorb as much ground water as possible.
Cacti are an example of this adaptation
Some plants in the desert have also developed a waxy coating of their leaves in order to prevent water loss through their leaves. This strategy is also used in Tropical rain forests to help water run off leaves and prevent fungus and bacteria from growing.
This cactus has a waxy coating to help prevent water from escaping
Underwater plants do not have sufficient means of transporting water, so instead they have adapted to absorb water, nutrients, and gases through the leaves directly from the water.
This rainforest plant is preventing fungus growth by having waxy leaves
These Parrot's Feather plants (myriophyllum aquaticum) have adapted their leaves so that they can be completely submerged in water.
Plants in boreal forests have adapted so that their leaves are dark in color. This way more solar heat can be absorbed. Also their needle like leaves shed snow more efficiently.
Pine trees are an example of a boreal forest plant with needle like leaves.
This desert cactus has adapted its roots so that they are longer than the plant itself and run deep into the ground.
Prairie grasses have adapted extensive root systems, or fibrous roots so they can avoid animals or weather coming along and completely removing them from the ground.
Roots in tropical rainforests have shallow roots so that they can capture the abundance of nutrients that are in the top layer of soil. (buttress roots)
These rainforest plants have buttress roots that practically lay on the surface of the soil in order to collect the maximum amount of nutrients.
Aquatic plants have fewer roots than land plants because their roots are only used as an anchoring devise and not a way of acquiring nutrients.
This Terraphyte plant has shallow and scrawny roots because it acquires its nutrients through its leaves instead.
Tundra plants have short stems so that they can be closer to the ground. This keeps the plant from freezing. and because the roots can not penetrate the permafrost.
This tundra moss is low to the ground to prevent freezing.
This Prairie grass is protecting itself from the ground hog by having extensive root systems
This maple tree is an example of a deciduous tree with thick bark.
In rain forest, a majority of the forest floor is covered in darkness. This is why some vine stems can grow as long as a tree limb in order to reach sunlight.
These vines have wrapped their stems around tree in order to reach the canopy of the rainforest.
Some plants called succulents store water in their stems. An example of this would be a desert cactus. That is why the cacti have green stems.
These cacti store water in their stems because it is so minimal in the desert.
These wildflowers can be found in the sub-tundra land in Alaska. Their cupped pedals help solar heat attract to their centers.
Some desert flowers only bloom at night so that they can attract pollinators that might not be as active during the day due to the extensive heat.
This flower is from a Cereus cactus which only blooms at night.
Plants on the floor of tropical rain forest have adapted their flowers to be designed so that they attract pollinators. This is due to the fact that there is very little wind to help with pollination.
These bright rain forest flowers attract pollinators to their plants.
Wildflowers in the temperate forests have adapted to bloom early in the season so they can receive necessary sunlight before the larger trees grow leaves and shade them.
These are examples of the flowers that grow in temperate forests.
Coconut trees have adapted themselves so that there fruit is hard, durable, and buoyant. This way if can last up to two months in salt water as it travels to other locations by ocean currents.
These coconuts have a tough buoyant husk.
Some seeds have adapted so their seeds are dispersed by wind. They have feather-like structures attached to them to assist in flight.
A dandelion is an example of wind dispersed seeds.
Some plants adapted barb like structures on their bodies so they stick to animals' fur.
Burdock seeds are an example barbed seeds
Some seeds produce fleshy or nut-like coverings around themselves so that animals will eat and distribute them.
Apples are inclosed by fruit in order to attract animals.
