The stimulus that produces growth of the plant toward light is called phototropism. It is caused by the presence of blue light, specifically light in the 440-470nm wavelength range, which is detected by the plant's photoreceptor molecule called phototropin. This photoreceptor triggers a signaling pathway that stimulates cell elongation on the shaded side of the plant, resulting in growth towards the light source.

What is response of photo tropism?
Light. Tropisms are growth responses to stimuli. Photo-tropism = light-growth
What is growth movement of a plant toward the light called?
phototropism.
Which type of response is the growth of a flower toward light?
I think you're talking about phototropism.
How does a paramecium carries out the 7 life characteristics?
A paramecium carries out the seven life characteristics as follows: Organization - it has specialized structures like cilia and a contractile vacuole Metabolism - it takes in nutrients and produces energy through cellular respiration Homeostasis - it maintains internal conditions through contractile vacuoles and ion pumps Growth - it grows by increasing in cell size and reproduces asexually by binary fission Adaptation - it can adapt to changing environments through behaviors like moving toward food Response to stimuli - it can respond to environmental cues like light or temperature changes Reproduction - it reproduces asexually by binary fission and can also undergo conjugation for genetic diversity.
What is the word for a Plant that grows towards the light?
phototropic (details from another answer) movement of or growth of plant in response to external stimulus. e.g. growth of root towards gravity - geotropism growth of shoot towards the light - phototropism hydrotropism is exhibited by lengthening of roots towards water source and finally, thigmotropism is growth towards solid objects -support by climbers
What is the difference between taxis and tropism?
Tropism: is the growth response of a plant that results from certain stimuli. Tropism can be positive, in which case the plant will bend toward the stimulus, or negative, in which case the plant will bend away from stimulus. Taxis: Taxis in animals is the responsive movement of going toward or away from an external stimulus.
Explain how both external and internal stimuli are involved in your action?
External stimuli come from the environment and can influence your actions by triggering responses based on what you see, hear, or feel. Internal stimuli, on the other hand, originate from within your body, such as hunger or pain, and can also lead to behaviors like eating or seeking relief. Together, external and internal stimuli interact to guide your actions in various situations.
What is response of photo tropism?
Light. Tropisms are growth responses to stimuli. Photo-tropism = light-growth
Why do animals respond quickly to external stimuli?
It's a survival mechanism. Reacting quickly can mean the difference between life and death in some situations (ie- a large boulder rolling down a hill toward an animal; that animal is going to move as soon as they notice the boulder). In other cases, external stimuli could mean something good, like sunlight signalling the beginning of the day and thus the beginning of a diurnal animal's activity period.
You observe a plant on your windowsill that grow at an angle toward the outside This is an example of a living things?
Yes, the plant growing towards the light is an example of a living thing exhibiting a tropism, specifically phototropism. This is a plant's natural response to light as it seeks to maximize photosynthesis for energy production.
What is the secondary meristems that produces wood toward the inside and bark toward the outside of a tree?

vascular cambium
What is that secondary meristem that produces wood toward that inside and bark toward that outside of a tree?
vascular cambium
What is the secondary meristem that produces wood toward the inside and bark toward the outside of a tree?
The secondary meristem that produces wood toward the inside and bark toward the outside of a tree is called the vascular cambium. It is a lateral meristem responsible for the secondary growth in plants, leading to the formation of secondary xylem (wood) and secondary phloem (bark).
How humans respond to internal and external stimuli?
Humans respond to internal stimuli, such as hunger or pain, through physiological processes like increasing heart rate or releasing hormones. External stimuli, like loud noises or bright lights, are detected by sensory organs and processed by the brain, leading to responses like moving away from danger or seeking out rewards. Overall, these responses are critical for survival and maintaining homeostasis.
