If a plant is deprived of sunlight, it will start using its starch reserves for energy. If it runs out, it will start to die.
The answer is the organism from the plant to the sunlight
Phototropism is the change in the way a plant grows in response to sunlight. This process involves the plant bending towards the light source to optimize its exposure to sunlight for photosynthesis.
It is a tropism, specifically phototropism.
Not in the leaves
Lack of sunlight
Chloroplasts need sunlight for its function. So leaves have more chloroplasts
If an aquatic plant is submerged in a beaker of water and exposed to sunlight, you would expect to observe the process of photosynthesis. This would likely result in the production of oxygen bubbles, which may be visible rising to the surface of the water. Additionally, the plant may show signs of growth or increased vibrancy in its color as it utilizes sunlight to convert carbon dioxide and water into glucose. Overall, the plant's health and activity would improve with adequate light exposure.
brown(no sunlight=dead plant)
For example a pot that has not fallen down
my thoughts are this a plant has a specific volume need for water it can vary based on availability of sunlight and how much room the roots have to grow as well as species type and place of origin. To much water can often kill a plant as surely as not enough. If your plant isn't growing and it is not waterlogged or deprived of sunlight (which it needs to effectively fuel its use of the water and soil nutrients) check if its roots are cramped or the water may have a substance that kills the plant.
A plants architecture determines the response to sunlight, but all plants require light to survive. Phototropism is the name assigned to the movement the makes to maximize its sun source.
A plant's response to touch, known as thigmotropism, can stimulate growth and development by triggering the release of hormones that promote cell division and elongation. This response helps the plant adapt to its environment, strengthen its structure, and enhance its ability to capture sunlight for photosynthesis, ultimately leading to improved overall growth and development.
