Optically active
Placids typically contain pigments like chlorophyll a, chlorophyll b, and carotenoids that absorb various wavelengths of light for photosynthesis. These pigments help capture light energy and convert it into chemical energy for plant growth and development.
Chlorophylls, carotenoids, and phycobilins are the substances in plastids that absorb various wavelengths of light for photosynthesis. Each pigment absorbs different wavelengths of light to maximize the capture of energy for photosynthesis.
Materials such as black paint, charcoal, and dark fabric are known to absorb light well. These materials contain pigments or substances that effectively trap and convert light energy into heat, preventing it from being reflected or transmitted.
Darker objects absorb more energy than lighter ones because they absorb a greater amount of light and convert it into heat. Lighter objects reflect more light, which means they absorb less energy.
UV light is invisible to the human eye, which is why it is sometimes referred to as 'black light'. However, some materials (e.g. DayGlo) can absorb UV energy and convert it into visible light energy. They are said to be fluorescent.
Substances that absorb light convert it to various forms of energy, such as heat or electrical energy. This process is known as photovoltaic effect and is utilized in solar panels to generate electricity from sunlight.

Chlorophylls and carotenoids are the main pigments found in plastids that absorb various wavelengths of light in photosynthesis. These pigments help capture and convert light energy into chemical energy to drive the process of photosynthesis in plants.
Bacteria that can absorb light energy and convert it into ATP are commonly called phototrophic bacteria. They use light as an energy source for photosynthesis, similar to plants.
Placids typically contain pigments like chlorophyll a, chlorophyll b, and carotenoids that absorb various wavelengths of light for photosynthesis. These pigments help capture light energy and convert it into chemical energy for plant growth and development.
They are energy transformers. They convert light energy to chemical energy
Chlorophylls, carotenoids, and phycobilins are the substances in plastids that absorb various wavelengths of light for photosynthesis. Each pigment absorbs different wavelengths of light to maximize the capture of energy for photosynthesis.
Substances that absorb light can be converted to higher energy states, leading to excitation or even a chemical reaction. This absorption of light can lead to various phenomena like fluorescence, phosphorescence, or photochemical reactions, depending on the specific molecule and conditions.
Materials such as black paint, charcoal, and dark fabric are known to absorb light well. These materials contain pigments or substances that effectively trap and convert light energy into heat, preventing it from being reflected or transmitted.
Darker objects absorb more energy than lighter ones because they absorb a greater amount of light and convert it into heat. Lighter objects reflect more light, which means they absorb less energy.
UV has higher energy (per photon) than visible light.
Chlorophyll a and chlorophyll b are the main molecules in chloroplasts that can absorb light for photosynthesis. These pigments absorb light energy and convert it into chemical energy, which is used to drive the process of photosynthesis.
