Distinguish nastic non directional movements from tropic responses?
Nastic movements are non-directional responses to external stimuli, triggered by changes in environmental factors like temperature or humidity. These movements are not correlated with the direction of the stimulus. Tropic responses, on the other hand, involve directional growth or movement of an organism in response to a stimulus, such as phototropism (response to light) or gravitropism (response to gravity).
What are the 3 types of plant responses?
Plants exhibit three main types of responses: tropisms, nastic movements, and growth responses. Tropisms are directional growth responses to environmental stimuli, such as phototropism (response to light) and gravitropism (response to gravity). Nastic movements are non-directional responses to stimuli, like the opening and closing of flowers or leaves in response to changes in light or temperature. Growth responses involve changes in growth patterns, often influenced by hormones, to adapt to environmental conditions.
What is a directional plant response?
A directional plant response, also known as tropism, is the growth or movement of a plant in response to a directional stimulus, such as light, gravity, or touch. For example, phototropism is when a plant grows towards a light source. These responses allow plants to adjust their growth and development to optimize their chances of survival and reproduction.
Do slaters react to light?
Yes, slaters (woodlice) are negatively phototactic, meaning they will move away from light. They are more active in the dark and prefer to stay hidden in dark, moist areas during the day.
What are the three aspects of light that affect plant growth?
The three aspects of light that affect plant growth are intensity (brightness), duration (photoperiod), and quality (specific wavelengths). Intensity affects the rate of photosynthesis, duration influences plant development and flowering, and quality triggers specific responses like phototropism and photomorphogenesis.

The two main types of plant responses are tropic responses and nastic responses?
Tropic responses are called tropism. It is the growth or turning movement of plants in response to an environmental stimulus. Nastic movements are non-directional responses to stimuli, independent of the stimulus's position.

What is the answer to growth in response to a stimulus?
The growth in response to a stimulus is called tropism. Tropisms are directional growth responses exhibited by plants or organisms in response to specific environmental cues such as light, gravity, or touch. These growth responses help the organism to adapt and survive in its environment.
What is the difference between candela, lumens, and lux, and how do they each measure the brightness or intensity of light?
Candela measures the intensity of light emitted in a specific direction, lumens measure the total amount of light emitted by a source, and lux measures the amount of light that falls on a surface. Candela is used for directional light sources like flashlights, lumens for overall brightness of a light source, and lux for the brightness of light on a surface.
What is the condition sensed in light sensors?
Light sensors detect the intensity of light in their surroundings. They convert this light energy into electrical signals that can be measured and used for various purposes, such as adjusting the brightness of a display or triggering automated responses in smart devices.

Intensity affects the rate of photosynthesis, duration influences plant development and flowering, and quality triggers specific responses like phototropism and photomorphogenesis.
What is the light intensity in the arctic?
The light intensity is poop!
What is nastic response?
Nastic responses are non-directional movements of plants in response to stimuli, such as light, touch, or temperature, that do not involve growth towards or away from the stimulus. These movements occur quickly and are often reversible, such as the closing of a Venus flytrap upon prey contact or the opening and closing of flower petals. Unlike tropic responses, which are directional, nastic movements are influenced by internal factors rather than the direction of the external stimulus.
What is the relationship between the intensity and energy of light?
The relationship between the intensity and energy of light is that the intensity of light is directly proportional to its energy. This means that as the intensity of light increases, so does its energy.
