JAWABAN 40 Soal Bahasa Inggris Kelas 11 Semester 1 dan Kunci Jawaban Ujian Sekolah PAS/SAS Terbaru

In most plants, the water used in photosynthesis is absorbed from the soil by the roots and trans- located through the xylem of the root and stem to the leaves.

Except for the usually small percentage used in respiration, the oxygen released in the process diffuses out of the leaf into the atmosphere through the stomata.

Oxygen is the product of the reaction. For each molecule of carbon dioxide used, one molecule of oxygen is released.

A summary chemical equation for photosynthesis is: As a result of this process, radiant energy from the sun is stored as chemical energy.

In turn the chemical energy is used to decompose carbon dioxide and water.

The products of their decomposition are recombined into a new compound, which is successively built up into more and more complex substances.

After many intermediate steps, sugar is produced.

At the same time, a balance of gases is preserved in the atmosphere.
