Germinating seeds respond to environmental cues such as gravity and light to determine which way to grow. Gravity causes the root to grow downward (gravitropism), while light triggers the stem to grow upward (phototropism). This helps the seedling establish proper orientation for optimal growth and nutrient absorption.
Light is considered an external stimulus for a plant. It influences various growth and developmental processes, such as photosynthesis, phototropism, and flowering. Plants respond to light through mechanisms like photoreceptors, which allow them to adapt to their environment. These responses are crucial for maximizing energy capture and optimizing growth.
A plant would respond to light by growing towards a light source through phototropism. It would also respond to touch or contact by curling its leaves to avoid or protect itself from potential harm through thigmotropism.

Auxin promotes geotropism by redistributing through the plant in response to gravity. In roots, auxin accumulates on the lower side causing elongation of cells and downward growth, while in shoots, it accumulates on the upper side causing inhibition of elongation and upward growth. This differential distribution of auxin helps plants respond to gravity and grow in the right direction.

Certain plants react to gravity by growing against it or towards it. It is the tropism of gravity called a geotropism. For example, if a potted plant falls over then it will continue to grow towards the sky. If a mudslide occurs and it drastically tilts the land where a tree grows, the tropism allows the tree to grow upwards. Alternatively, geotropism works for roots as well. Roots will respond to gravity by growing downwards. It can be observed that no matter which way a seed is planted the roots and the shoots respond to gravity in opposite ways. Plant hormones, auxins are responsible for this response. Phototropism is the response of plants to light.

I believe what you are referring to is called Phototropism, which describes the way plants and some fungi respond to light.
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.

Tropism is a biological phenomenon where an organism responds to the stimulus brought by the environmental factors. Some examples include: chemotropism, heliotropism, phototropism, thermotropism and electrotropism.
True. Hunger is internal, a voice is external.

Plants respond to light through a process called phototropism, where they grow towards light sources to maximize photosynthesis. Light is essential for plants to produce energy through photosynthesis, so they have evolved to detect and respond to light cues for optimal growth and development.
The stimuli that plants respond to include light, water and gravity. Plants grow towards light (phototropism). Also in some plants the flowers will follow the sun as it moves across the sky. Plant roots grow towards water (hydrotropism). Plant roots grow towards gravity/towards the centre of the earth (geotropism). Source(s): I'm a Biology teacher. this is bullcrap it is fake
