AP BIOLOGY

Detailed explanation-1: -The correct option is A True. During photosynthesis, Carbon dioxide(CO2) gas is taken in through stomata from the atmosphere. Oxygen(O2) gas is released through stomata into the atmosphere as a by-product.

Detailed explanation-2: -Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product.

Detailed explanation-3: -In photosynthesis, solar energy is harvested and converted to chemical energy in the form of glucose using water and carbon dioxide. Oxygen is released as a byproduct.

Detailed explanation-4: -The products of photosynthesis are glucose and oxygen. Although the hydrogen atoms from the water molecules are used in the photosynthesis reactions, the oxygen molecules are released as oxygen gas (O2). (This is good news for organisms like humans and plants that use oxygen to carry out cellular respiration!)

Detailed explanation-5: -The oxygen released during photosynthesis is from the water. The plants will absorb water as well as carbon dioxide during photosynthesis. Later these water molecules are converted into oxygen and sugar.
