Describe what you think is happening during photosynthesis.
boyakko [2]

Answer:

During photosynthesis, plants take in carbon dioxide (CO 2) and water (H 2 O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

Explanation:

The energy for photosynthesis comes from light. Light energy is converted to chemical energy by chlorophyll. There are two sets of reactions, light dependent and light independent. The process mostly takes place in the chloroplasts of plant leaf mesophyll cells. Photosynthesis is the process where a plants uses the sun’s energy to turn light into chlorophyll. Plants produce oxygen during this process and utilize carbon dioxide. Photosynthesis is the single most important chemical process on the earth. Almost all plants needs the sun in order to survive Photosynthesis is the most important chemical process on earth – it provides food and energy for all living creatures who eat the plants that rely on this process to produce their food (glucose). · More than half (70%) of the world’s oxygen is produced by phytoplankton photosynthesis in the world’s oceans.

NISA [10]
Marie is experiencing the: Sympathomimetic effects (fight-or-flight state).

The sympathetic nervous system is a component of the autonomic nervous system, managing the activity of visceral organs and the automatic functions of the body, such as breathing or beating of the heart. The sympathetic nervous system is involved in many unconscious physiological activities through two neuromodulators of the catecholamine family: adrenaline, but especially norepinephrine (fight-or-flight hormones).
* It accelerates the metabolism and is activated for example in case of danger or fear, to prepare the individual to escape.
* It affects the cardiovascular system: it increases the heart rate and induces peripheral vasoconstriction, causing an increase in blood pressure.
* At the digestive level, it slows the muscular contractions of the intestines but promotes the release of glucose by the liver.
* It also has a bronchodilator effect, that is to say, it causes the increase of the diameter of the bronchi.
