Plant Growth and Morphogenesis under Different Gravity

Plants have utilized gravity as the most stable and reliable signal for their survival over the course of evolution. Microgravity is one of the most significant features of orbital flight in space. Thus, we predict that plant growth and morphogenesis will be greatly modified under space conditions.

Plant Sensory Systems and Responses Boundless Biology

Plant Responses to Gravity. Whether or not they germinate in the light or in total darkness, shoots usually sprout up from the ground, while roots grow downward into the ground. A plant laid on its side in the dark will send shoots upward when given enough time. Gravitropism ensures that roots grow into the soil and that shoots grow toward

How Does Gravity Affect Root Growth? BioEd Online

Plants'' growth response to gravity is known as gravitropism the growth response to light is phototropism. Both tropisms are controlled by plant growth hormones.

Fun Gravity Facts for Kids

Fun Facts. Even though the idea of gravity is pretty obvious, scientists didn''t have a word for it or a real understanding of it until 1687, when Sir Isaac Newton published his theories on the Three Laws of Motion. Mass determines how much gravity something has, but proximity (closeness) plays a part too.

What are plant auxins? And how do they affect plant growth?

Auxins are a powerful growth hormone produced naturally by plants. They are found in shoot and root tips and promote cell division, stem and root growth. They can also drastically affect plant orientation by promoting cell division to one side of the plant in response to sunlight and gravity. Auxins have four key effects on plant growth:
