Tropism: The Way Plants Survive – TrioPlantBased

WebOn Earth, aerial parts of the plant (shoots) grow upward while roots grow downward. However, the experiments showed that in a microgravity environment, the growth direction is unregulated, and some roots even extend in the same direction as the aerial stems (Figure 1). In the case of root gravitropism, the hypothesis is that gravity is ... WebTo do this, they have to go where the water and minerals are. Most plants are located in areas where all the yummy "plant food" is far below the surface. This means that roots need to always travel down into the ground to find and retrieve all the water and minerals that the rest of the plant needs to survive. WebRoots grow downward, or towards the center of Earth, and away from light. These responses to external stimuli are called tropisms. Plants’ growth response to gravity is known as gravitropism; the growth response to light is phototropism. Both tropisms are controlled by plant growth hormones.
