Fotosintesis

Lab2 - Week 3


What is the importance of the light and dark reactions in photosynthesis?
The importance of these two processes is that from these products, the plant produces lipids and proteinsnecessary for the formation of plant tissue, resulting in growth.
What happens to food energy during photosynthesis? During cellular respiration?
Plants get food the organic matter of they produce,and use it to build their tissues and obtain energy for life. This energy is obtained through breathing. In this process the oxygen that plants capture from the air reacts with the sugars that areformed during the process of photosynthesis. The process of respiration occurs in mitochondria, as far as oxygen. There, through a series of chemical reactions, it decomposes the sugar and you getenergy from food.
Respiration also produces energy, carbon dioxide and water. Carbon dioxide is carried to the stomata. From there it can spread to the outside or can be used by leaves forphotosynthesis. The plants are fed through of photosynthesis is produced in chloroplasts, principalmentede leaves. They use sunlight, carbon dioxide, which take air and water absorbed from the earth.
Why isphotosynthesis important to you?
Life on our planet is maintained primarily thanks to photosynthesis process by algae in the aquatic environment and plants on land, which have the ability to synthesizeorganic matter is essential for the creation of living beings, from the light and inorganic matter.
Almost all the energy consumed by the life of the terrestrial biosphere comes fromphotosynthesis.
What are the processes in cellular respiration?
Cellular respiration, the process used by most animal and plant cells, is the degradation of biomolecules to produce the necessary energy release,and so the body can carry out their vital functions. Through the degradation of glucose pyruvic acid is formed. This acid breaks down into carbon dioxide and water, generating ATP molecules. Cellular...
