The role of pigments in the photosynthesis reaction is to

start the reaction by absorbing light energy
pass the energy on to the dark reaction
give color to the plant
form the glucose molecule

Option A, Start the reaction by absorbing light energy

Explanation:

Chlorophyll is a green color pigment in plant that helps in entrapping sunlight. Being green in color, it absorbs the blue and red light and reflects the green light. The molecules of chlorophyll gains energy from sunlight and then jumps to higher energy levels by the process known as photo excitation. These excited molecules get ionized to further initiate the process of photosynthesis.

Hence, option A is correct.

Start the reaction by absorbing light energy

Explanation:

Photosynthetic pigments are substances present in the chloroplasts of autotrophic beings. They have the function of absorbing light, triggering the photochemical reactions of photosynthesis, a fundamental process for the maintenance of life on the planet. With this, we can say that the role of pigments in the photosynthesis reaction is to initiate the reaction by absorbing light energy.

The different pigments (chlorophylls and carotenoids) absorb different wavelengths of sunlight, which is the main energy source on the planet.

true is the final answer!

answer: grassland biomes are closer to the equator and receive more rain.

grasslands are biomes that are dominated by grasses rather shrubs and trees. savanna are biomes that exhibit grasses, shrubs and small tree as vegetation. grasslands are located near the equator of the earth. these are found in north america. savanna biomes are found in africa, south america, australia and india. grassland exhibit moderate climatic conditions, it receives   amount of rainfall higher than savanna.   therefore, savanna exhibit dry and hot climatic conditions.
