Explanation:
Photosystems are the practical components for photosynthesis, well-defined by a specific stain association and connotation patterns, whose work is the absorption and allocation of light energy, which suggests transfer of electrons. Physically, photosystems are initiate in the thylakoid membranes. A photosystem consists of a light-harvesting complex and a reaction center. Pigments in the light-harvesting complex pass light energy to two special chlorophyll a molecules in the reaction center. Photosystem I or PS I and Photosystem II or PS II are the protein-mediated complex, and the main aim is to produce energy (ATP and 
), which is used in Calvin cycle, the PSI uses light energy to convert NADP+ to .
<u>Answer:</u>
<em>Land and sea breeze are produced because the land changes temperature rapidly than the ocean.
</em>
<u>Explanation:</u>
<em>The rates of heating up of land and sea are different. Land gets heated up faster than water. Temperature is crucial in determining the density of air.
</em>
When land gets heated up the air near the land turns hot and this temperature is greater than the temperature of the air near the water surface. <em>Hotter air has less density than the air which is relatively less warm. Density difference creates pressure difference.
</em>
Denser air has higher pressure than less dense air making air move from area of high pressure to area of low pressure. During the day<em> the land is heated up more and thus air move from sea to land and it is called sea breeze. </em>Just like it absorbs heat land releases heat at a faster rate.
<em>Thus at night land the sea will be warmer than the sea and thus air will move from the land to the sea and it is called land breeze.

Plants and animals are both "organisms" or "living organisms" if you prefer.
An organism is basically a group of different organs functioning together (hope this was the easiest way to explain it).
Hope it helped,
Happy study/ homework/ exam!
