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

What is a tropical shrub with leaves sensitive to touch or light?
A tropical shrub with leaves sensitive to touch or light is likely to be a Mimosa pudica plant, also known as the sensitive plant or touch-me-not. When the leaves are touched or exposed to light, they exhibit rapid leaf movement in response to physical stimulation.
What is the mechanism that causes mimosa leaves to close?
Mimosa leaves close in response to touch due to a rapid movement of ions across cell membranes, causing changes in cell turgor pressure. This movement is triggered by the stimulation of specialized cells known as pulvini, which act as sensitive valves controlling the leaf movement.
The leaves of a sensitive plant close whenever any part of the leaf is touched because of a?
rapid response to mechanical stimulation due to specialized cells called motor cells, which trigger the movement of water out of leaf cells, leading to a loss of turgor pressure, causing the leaves to fold in response to touch stimuli.
What do rayographs British algae cyanotype impressions and leaves on light sensitive paper have in common?
Photogram
Which plant folds it leaves when touched?
The Mimosa pudica, also known as the sensitive plant or touch-me-not, folds its leaves when touched as a defense mechanism to deter predators.
What is a tropical shrub with leaves sensitive to touch or light?
A tropical shrub with leaves sensitive to touch or light is likely to be a Mimosa pudica plant, also known as the sensitive plant or touch-me-not. When the leaves are touched or exposed to light, they exhibit rapid leaf movement in response to physical stimulation.
Types of responses tropism tasas and nastism?
Tropism: a growth response of a plant towards or away from a stimulus, such as light or gravity. Taxis: a directed movement of an organism towards or away from a stimulus, such as movement towards food or away from danger. Nastic movement: a non-directional response of plants to a stimulus, like the folding of leaves in response to touch or changes in humidity.
What is the mechanism that causes mimosa leaves to close?
Mimosa leaves close in response to touch due to a rapid movement of ions across cell membranes, causing changes in cell turgor pressure. This movement is triggered by the stimulation of specialized cells known as pulvini, which act as sensitive valves controlling the leaf movement.
What is the difference between phototropism and geotropism?
Phototropism - towards light. Think plants, flowers, leaves. They generally turn towards light.Geotropism - towards the earth. Go figure.Hydrotropism - towards water or towards moisture.
What are the unique characteristics of the sensitive plant flower that make it so intriguing to botanists and gardeners alike?
The sensitive plant flower is intriguing due to its unique ability to fold its leaves in response to touch or movement, a phenomenon known as thigmonasty. This plant also has delicate pink flowers and fern-like leaves, making it visually appealing to both botanists and gardeners.
How can koalas tell the difference between different types of eucalypt leaves?
The koala has an acutely sensitive nose, which enables it to detect subtle scent differences between different species of gum trees.
How are the movement of energy and the movement of chemicals in ecosystem different?
Energy is not recycled, it flows in and out in a unidirection. Chemical energy enters as light energy and is produced by producers and leaves the ecosystem as heat.
Is milkweed contagious?
Some people are sensitive to the leaves and sap but the plant is not contagious.
Why do sensitive plants close their leaves when touched?
Sensitive plants close their leaves when touched as a defense mechanism to protect themselves from potential harm or threats. This rapid response is triggered by physical contact, which signals the plant to close its leaves in order to deter predators or prevent damage.
How does movement takes place in plants?
They grow both up and down and also towards the light. Leaves also fall off trees, and plants sag towards the gropund when they are short of water or dying. Other than this, they don't really move, unless they are triffids.
The leaves of a sensitive plant close whenever any part of the leaf is touched because of a?
rapid response to mechanical stimulation due to specialized cells called motor cells, which trigger the movement of water out of leaf cells, leading to a loss of turgor pressure, causing the leaves to fold in response to touch stimuli.
Why makahiya leaves sensitive?
Makahiya leaves are sensitive because they have specialized cells on the leaf surface called pulvini, which respond to touch or physical stimulus. When these cells are touched, they rapidly lose water, causing the leaflets to close in a defensive response to protect themselves from potential harm or herbivores.
