Basic products of photosynthesis

Photosynthesis occurs inside chloroplasts. Chloroplasts contain chlorophyll, a green pigment found inside the thylakoid membranes. These chlorophyll molecules are arranged in groups called photosystems. There are two types of photosystems, Photosystem II and Photosystem I. When a chlorophyll molecule absorbs light, the energy from this light raises an electron within the chlorophyll molecule to a higher energy state. The chlorophyll molecule is then said to be photoactivated. Excited electron anywhere within the photosystem are then passed on from one chlorophyll molecule to the next until they reach a special chlorophyll molecule at the reaction centre of the photosystem. This special chlorophyll molecule then passes on the excited electron to a chain of electron carriers.

Plants have two ways of moving water from outside the root toward the inside of the root to the xylem and phloem tissue. Water can flow between the cell walls of adjacent cells. Think of this area as a hallway. Or water can flow between cells through tubes connecting the cytoplasm of each cell, much like people can walk through doors of adjoining rooms.

Photosynthesis is the process plants use ..

Phloem tissue contains cells called , which connect in columns called . Each sieve-tube element has a pore on the end of it, through which the cytoplasm from one sieve-tube element can “touch” the cytoplasm of the next sieve-tube element. This structure allows the fuel that the plant makes in the leaves to pass through and nourish the rest of the plant. This process is called .

Other products ofphotosynthesis are formed by incorporating mineral elements into theprocess.

Overview of Photosynthesis | Biology I

Most of the energyreleased both by the burning of fossil fuels and by the metabolism ofliving cells is given off as heat and must be replaced by thecontinued input of radiant energy from the Sun.The principal organic products of plant photosynthesis arecarbohydrates.

All living organisms on earth consist of one or more cells

Photophosphorylation is the production of ATP using the energy of sunlight. Photophosphorylation is made possible as a result of chemiosmosis. Chemiosmosis is the movement of ions across a selectively permeable membrane, down their concentration gradient. During photosynthesis, light is absorbed by chlorophyll molecules. Electrons within these molecules are then raised to a higher energy state. These electrons then travel through Photosystem II, a chain of electron carriers and Photosystem I. As the electrons travel through the chain of electron carriers, they release energy. This energy is used to pump hydrogen ions across the thylakoid membrane and into the space within the thylakoid. A concentration gradient of hydrogen ions forms within this space. These then move back across the thylakoid membrane, down their concentration gradient through ATP synthase. ATP synthase uses the energy released from the movement of hydrogen ions down their concentration gradient to synthesise ATP from ADP and inorganic phosphate.

The process involves a set of chemical reactions to convert chemical energy from the glucose molecules into ATP molecules.

The rate alsovaries with the plant species and its physiological state.Photosynthesis is not a single process but consists of a number ofphotochemical and enzymatic reactions.

Carbohydrates are typically stored as long polymers of glucose molecules with for structural support (e.g. , ) or for energy storage (e.g. , ). However, the strong affinity of most carbohydrates for water makes storage of large quantities of carbohydrates inefficient due to the large molecular weight of the solvated water-carbohydrate complex. In most organisms, excess carbohydrates are regularly catabolised to form , which is a feed stock for the pathway; , , and other are commonly used for long-term energy storage. The hydrophobic character of lipids makes them a much more compact form of energy storage than hydrophilic carbohydrates. However, animals, including humans, lack the necessary enzymatic machinery and so do not synthesize glucose from lipids, though glycerol can be converted to glucose.

Photosynthesis:Photosynthesis is the process by which green plants and certain otherorganisms transform light energy into chemical energy.

Formation of the simple carbohydrate glucose is shown by the equation

Plants must get food into their systems in order to acquire energy and continue living, similar to animals. Plants create energy for animals to use, so they must replenish their nutrients. And plants breathe, in a way. They take in the carbon dioxide that all the animals give off, and they give off oxygen for all the animals to use. Pretty cool design, isn’t it?
