In the presence of light it absorbs red light and reflects green light and carries out photosynthesis.
Why does plants grow taller in the dark. Why do plants grow towards the sunlight even in dark room. Plants get energy from light through a process called photosynthesis. This hormone tends to migrate to the dark side of the stem causing the stem cells to elongate much like those of plants in the closet.
Using energy from the sun or other light sources plants rearrange water and carbon dioxide to form sugar. Once a plant starts to grow it does require some light but this is not a given amount for all plants. Rapid growth may help the shoot to reach light.
For you to compare them. Without light photosynthesis cant work properly and without photosynthesis plants dont. Some seeds will germinate only in light some in darkness and for some the requirement for light is related to the temperature.

When the chlorophyll degrades it reveals the yellow cartenoid pigments that were there all along but just masked by the green chlorophyll. Observe them each day making sure you dont change anything. Plants that grow under high light intensities with a higher rate of photosynthesis are referred to as plants grown in light while plants that grow under low light intensities or dark conditions with a lower rate of photosynthesis are referred to as plants grown in the dark.
Without light a plant would not be able to. Accordingly plants are adapted to grow under different light intensities. Its a garden but no one would call it that at the moment.
The plants in the sun lit area thrives while the plants in the dark closet does not really grow taller as fast or at all and looks a lot more unhealthy because of the lack of light. This is how light affects the growth of a plant. However some require more than others.
