Like most plants, a bluebonnet begins as a seed under a blanket. When the time is right, the outer coat of the seed cracks to re
leaseee a tiny root tip. As the root tip begins to grow downward, the stem will begin to grow and push upward. How does the bluebonnet root knwo which way is down? How does the stem know whch way to stretch to reach sunlight? The answer is geotropism. This property of plants allows them to orient their growth with the direction of gravity. What phrase helps you determine what orient means? a. Property of plants b. To reach the sunlight c. How does the stem know d. With the direction of gravity
Geotropism or gravitropism is a coordinated process of plant growth in fungi and plants to respond to the changing gravity. It a general feature that are found in higher and lower altitude plants.
The roots show positive gravitropism and the stem negative gravitropism this they appear to be bend upside on a hill or slope. Can be seen with a potted plant, was the woody stems are capable of bending.
In light reactions, a molecule of chlorophyll absorbs one photon of light, causing a chlorophyll electron to transfer to a higher energy level. ... Chlorophyll then replaces the lost electrons from water molecules. The oxygen atoms form oxygen gas while the hydrogen atoms form protons and electrons.
