It is a tropism, specifically phototropism.
Tropism is the movement of a plant away from or toward a stimulus. The most easily found example of tropism is a plant's response to light. Plants tend to grow toward the light. This tendency is called 'phototropism'.
Plants are able to bend or grow towards a stimulus (e.g. sunlight). The growing towards a stimulus is maintained by production of growth hormones which are produced due to signal cascades from photoreceptor proteins in plant's cells. Bending is gained by changing the water pressure in vacuoles of the cells.
By evolution, it could develop thorns to keep consumers away. Some plants store bitter substances in their vacuoles to stop consumers from consuming the whole plant. Also, plants tend to bend toward the direction of sunlight to increase their production of "food" by photosynthesis.
This is due to tropic movement(tropism) in plants in which the fixed part of a plant(such as stem) moves in response to a stimulus.If the stimulus is light(as you have asked) then it is termed as Phototropism.And further more stem shows positive phototropism.
Yes plants do grow towards sunlight that is why some plants lean to a certain side.
The action is called phototropism. The most obvious examples are houseplants that lean toward windows, and hedges that grow new branches at the bottom that arch up along their sides.
its an response :)
they are actions that a plant takes in order to increase its chance of survival. An example of a behavioral adaptation in plants are tropisms. Tropisms are the growth of plants toward sunlight.
Plants use sunlight to make energy and most plants tend to take in sunlight through their leaves and/or petals (of the flowers) because they are the broadest part of the plant (and therefore have the most "receptors" for the light). This is why the plants often seem to "turn" toward the sun. In other words, if a plant only gets sun from one direction, its leaves will be turned in that direction to collect the sunlight and it may grow in that direction (either on a tilt or send runners out that way). Some plants (such as sunflower) move with the sun throughout the day to maximize the amount of sunlight it collects. Short answer, plants generally grow toward the sun (or the direction where they get the most sunlight).

We know that green plants make their food by the process of photosynthesis. The leaves of the green plants contain a green pigment called chlorophyll. Chlorophyll converts water from the soil and carbon dioxide from the air into oxygen and sugar. Oxygen is then released into the air and sugar is taken as food by the plant. But this entire process of making food can only be done in the presence of sunlight. The leaves, therefore, lean towards the light for photosynthesis. Without sunlight green plants cannot survive.
Plants bend as they need light for photosynthesis. Its scientific term is phototropism.
The plant would grow toward the sun because all plants love the sun. Also they grow toward the sun so it will be easier to get sunlight.
A growth hormone called auxin.
Every step of the problem leads toward the climax. That's called rising action.
Yes, they respond very well to sunlight because i have a plant in my room that is near the window and it has full access to the sunlight and whenever the sunlight hits the plant, it leans toward the sun's direction. When the plant fully grew, it was beyond healthy and had a pretty green colour.
