Upon exposure to blue light, plants not only begin to grow toward the light, but move their chloroplasts to the sunny side of each cell. the adaptive advantage of moving chloroplasts to the sunny side of each cell ) maximizes light absorption by the chloroplasts for photosynthesis
b) increases production of phototropic hormones
c) maximizes heat absorption by the chloroplasts for cellular respiration
d) increases adenosine triphosphate (atp) production during the light-independent reactions

A) maximizes light absorption by the chloroplasts for photosynthesis

Explanation:

Chloroplasts are the double membrane-bound organelles present in the leaf cells. Chloroplasts contain light-absorbing pigment chlorophyll that absorbs maximum light of blue and red wavelengths.

Absorption of light by chlorophyll pigments drives the light reactions of photosynthesis which in turn provide ATP and NADPH to fix carbon dioxide gas into glucose by light-independent reactions. The process of photosynthesis produces glucose which in turn serves as an energy source for plants and supports their growth and development.

Therefore, exposure to blue light increases the rate of photosynthesis as chloroplasts in the leaf cells are aligned to absorb maximum blue light to support photosynthesis. And a higher rate of photosynthesis produces more glucose to support the growth of the plants.

plate tectonics and volcanic euptions

over time, plate tectonic processes cause continents to move to different positions on the globe.

for example, britain was near to the equator 300 million years ago, and therefore was hotter than it is today. for further details look at our climate through time poster or online map.

the movement of the plates also causes volcanoes and mountains to form and these too can contribute to a change in climate.

mountain ranges formed by plate tectonics. large mountain chains can influence the circulation of air around the globe, and consequently influence the climate.   warm air might be deflected somewhere cooler by the mountains.
