Armor. Spines protect the plant from hungry and thirsty animals (including humans). Animals need water and nutrients to stay alive. Plants are a great source of water and nutrients for animals, but plants need to hold onto their own water and nutrients! Armor is an adaptation to protect the plant from hungry animals. The spines also provide shade to this desert plant.

On this tree, the spines on the trunk are root thorns. The spines are modified roots! If we look under the microscope, we can see that the spiny structures on the stem of Cryosophila albida have the internal anatomy of a root, not a stem.

Stilt Roots. Stilt roots grow partially above the earth and help the plant stay in one place. In wet environments, the ground can move around a lot! To help the plant stay in one place and not fall over, stilt roots grow outward at an angle. Stilt roots are an adaptation that help the plant grow tall in wet soil.

Tall Trunk. The rainforest has four layers (emergent, canopy, understory, and forest floor). Each of these layers blocks out sunlight. To access sunlight, some plants have adapted tall, strong, woody stems. These tree trunk stems support the plant in growing tall so its leaves can reach a higher layer of the rainforest. At higher layers, plants can access more sunlight for photosynthesis.
