In what direction does a shoot grow?
It grows where the seedling is facing
How does gravity affect bean seeds planted in four different directions and how will this affect farmers?
Gravity affects seed germination by altering the placement of plant hormones which affect the direction the first root grows and the direction the shoot grows. Gravity pulls some hormones downward which cause roots to grow down while the shortage of that hormone plus the presence of other hormones cause the shoot to grow upward. It doe not matter which way the seed is planted, this will not have an effect of the developing seedling.
The plant needs light to grow. So, the shoot has a tendency to grow towards the direction of light to receive more of it. The above result can be obtained by a simple school project involving growing of common beans in a cup, and keeping it in a shoe box with only one hole in the corner for light to enter.
Tropisms are growthg responses in plants in which the direction of growth depends on the direction of the stimulus. Phototropism is the response to light. The shoots of plants are positively phototropic (grow towards the light) while the roots are negatively phototropic (grow away from light). Experiments carried out in 1880 by Charles Darwin and his son Francis showed that the stimulus was detected by the tip of the shoot but the bending response took…
When seeds germinate they are under the ground and as such are not able to detect any light source to grow towards however they are able detect the force of gravity just like humans do. No matter which way round you plant a seed the roots always grow down and the shoot grows up, the roots show positive geotropism (this means they grow in the same direction as the pull of gravity i.e. down) and…
No, they can grow no matter which direction they are facing. They have a tendancy to grow opposite of a gravatational pull, so the seed would probably swell, burst and grow in every direction. The roots would grow in between the stems. It would live, if in the right environment (e. g. light, water, nourishment)
How is the movement of leaves of the sensitive plant different from the movement of a shoot towards light?
movement in sensitive plants : d movement in sensitive plant leaves takes place in response to touch stimulus.eg:touch-me-not plant movement of a shoot towards light: When sunlight/light falls from 1 direction one shoot,d growth hormone auxin diffuses towards the shady side of shoot.this increased concentration of auxin stimulates the cells 2 grow longer on the shaded side of the shoot.dis enhanced growth 1 side cause bending of shoot 2wards light
A plant's growth response to gravity is called gravitropism or geotropism. Roots grow toward the pull of gravity while shoots grow away from the force of gravity. If a seed is planted on its side, the root and shoot will come out horizontally but the root will then grow turn and toward the pull of gravity and the shoot will turn and grow away from the force of gravity.
The life cycle of a sunflower is: - you plant the seed - the root starts to grow out of the seed and spread into the soil (anchors the plant to the ground) - the shoot begins to come out of the seed in the opposite direction of the roots - the shoot grows into a sprout - the sprout starts to grow leaves - a bud starts to form - the bud starts to…
