Key points

• is a process that occurs in the leaves of a constitute and needs both and light energy.

• During photosynthesis, the chlorophyll in leaves help convert carbon dioxide and water into the products oxygen and glucose.

• The glucose acts as a vital source of food for the found.

• Carbon dioxide, water and lite are all needed for photosynthesis to have identify.

What is photosynthesis?

Photosynthesis takes place inside institute cells in modest objects called chloroplasts. Chloroplasts contain a green substance called chlorophyll. This absorbs the light free energy needed to make photosynthesis happen. Plants and algae can only carry out photosynthesis in the calorie-free.

Plants get carbon dioxide from the air through their leaves, and h2o from the ground through their roots. Light energy comes from the Lord's day.

The oxygen produced is released into the air from the leaves. The glucose produced can be turned into other substances, such as starch and plant oils, which are used equally an energy store. This energy can be released by

The head groundsman at Derby County FC discusses how he uses knowledge of photosynthesis to maintain the pitch.

---

Information technology's hugely important these pitches are admittedly pristine for the fans, the spectators, for the players, it'southward incredibly important. We have to accept a rubber surface so they're not getting injured, missing a shot, costing your team a chance for a win, the chance for a bays.

I'm Nathan Scarff, and I'm the Head Groundsman in Derby Canton Football Club.

Working within a stadium, we have a really big shade upshot. The darkest expanse in this pitch will never see any sunlight. The plants struggle to photosynthesise naturally, and so we utilise the lights to effectively synthetically induce the photosynthesis process and create the growth, so it gives the institute a lot of light energy and also some estrus too to encourage growth.

Nosotros are looking for only a healthy plant, something that's stiff, something that's durable, something that would recover well.

The sciences that we use is predominately biology, we take a multifariousness of measuring tools, nosotros'll measure the wet, the length of the grass, the hardness of the surface, everything is well-nigh producing absolute uniformity.

The offset year that we had these lights, we won the honor for best pitch in the championship. You lot do take a lot of pride away on what you do.

These are the things that plants need for photosynthesis:

• Carbon dioxide
• Water
• Light (a source of energy)

These are the things that plants make by photosynthesis:

• Glucose
• Oxygen

The word equation for photosynthesis in the presence of light and chlorophyll is:

Carbon dioxide + water → glucose + oxygen

Why is photosynthesis important?

Photosynthesis provides organisms with oxygen, a gas that many living things demand. Oxygen is a product of photosynthesis and is needed for respiration. All organisms respire to release energy and to stay alive.

Without photosynthesis, life as nosotros know it would come to an stop, as almost every depends on it either straight or indirectly. such every bit algae, seaweed, grasses and phytoplankton all require photosynthesis to make their own food.

Photosynthesis brings most a residual in the ecosystem as it decreases the concentration of carbon dioxide in the temper. Together with other processes such as respiration and , it can assistance to maintain levels of oxygen and carbon dioxide in the temper.

Without photosynthesis we wouldn't have fossil fuels such every bit coal and petroleum, every bit these were formed from photosynthetic processes. These non-renewable sources were made by the breakup of older plants.

Establish products such as timber, rubber and oil also crave photosynthesis to exist fabricated.

If a found cannot photosynthesise, it volition die

Plants and animals working together

The composition of the atmosphere has changed since the World was formed four.5 billion years ago. Natural processes, such as photosynthesis, accept contributed to maintaining the levels of oxygen and carbon dioxide in the atmosphere, required for survival.

Plants release oxygen into the atmosphere as a by-product of photosynthesis and processes such as respiration and release carbon dioxide into the atmosphere. These processes work , where plants and animals depend on each other to benefit from this. Plants need the carbon dioxide released past respiration and decomposition, whereas animals demand the oxygen released by plants from photosynthesis. This cycle helps maintain the balance of carbon dioxide and oxygen in the atmosphere.

Professor Brian Cox sees photosynthesis in activeness, investigating a unique blazon of jellyfish

---

Professor Brian Cox: All life depends on the period of energy, which gets passed from i life-course to another. And there is i creature that embodies more than almost just how that happens. This is the Aureate Jellyfish.

A unique subspecies only found in this 1 lake, on this 1 island, in the tiny Micronesian republic of Palau. Aureate Jellyfish have evolved to exercise something that very few other animals can do.' It really is incredible. As far as yous tin meet, all the way downwards, till the light vanishes, at that place are jellyfish. And you lot can see they've congregated in the sunday. If you go over there, to where the lake's in shade there are just none. So in this puddle of light beneath the dominicus, there are millions of them. Beautifully elegant things but floating effectually.

This lake is home to over 20 1000000 jellyfish, whose success comes down to a remarkable adaptation. Their bodies play host to thousands of other organisms. Photosynthetic algae that harvest free energy straight from sunlight. And once harvested, information technology's passed on to the jellyfish to employ.

The energy flows from sun, to algae, to jellyfish.' The ones at the surface are gently turning and, the reason they do that is to requite all their algae an equal dose of sunlight. 'And information technology's not just their beefcake that's adapted to harvest solar free energy. Every morning, as the sun rises the jellyfish begin to swim towards the due east.' And equally the sun tracks beyond the sky, they move back over again towards the w where they spend their nighttime. And then, the jellyfish have this beautiful, intimate, and complex relationship with the position of the sun in the sky. 'Every bit sunlight is captured by their algae it's converted into chemical energy. Energy they use to combine unproblematic molecules, water and carbon dioxide, to produce a far more complex one: glucose. Once captivated by the jellyfish, glucose, and other molecules, not merely power their daily voyage beyond the lake, they provide the basic edifice blocks the jellyfish utilize to grow the elegant and complex structures of their bodies.

So, the jellyfish, through their symbiotic algae, absorb the lite, the free energy, from the sun, and they use information technology to, well to alive, to ability their processes of life. And that's true, directly or indirectly, for every form of life on the surface of our planet. 'The sun's energy that bathes the Earth is harnessed past photosynthesis.

One time transformed, it's passed on from one lifeform to another as food. The flow of energy animates all living things.

The golden jellyfish has evolved to carry algae within their bodies and feed off the glucose the plants create.

The jellyfish motion towards the light of the Sun throughout the day to increase photosynthesis. The symbiotic relationship between the ii species allows the jellyfish to live off the glucose the algae produce.

Uses of glucose

Glucose is a useful molecule that is fabricated during the process of photosynthesis. The initial use for glucose, when broken down during respiration, is to release energy.

Glucose is a molecule that can be bonded together to make many types of including cellulose and starch (in plants) and glycogen (in animals). Remember of it like each glucose molecule being an private bead on a necklace and the entire necklace represents the saccharide molecule.

Plants only photosynthesise and glucose during the 24-hour interval when there is sunlight, but they use glucose for respiration all the time, including during the nighttime.

Cellulose

Glucose is used to brand cellulose. Cellulose is an example of a natural . Cellulose is the chief component found in plant jail cell walls and this gives the constitute cell force and support.

Humans cannot digest cellulose, but it is important in your diet as fibre. Fibre assists your digestive system, keeping food moving through the gut and pushing waste matter out of the body.

Starch

Other uses of glucose produced from photosynthesis is to make the insoluble storage molecule starch. Nigh plants including rice, potatoes and wheat store their energy as starch. Starch is too a polymer and can be converted dorsum to glucose by the constitute when it is needed, for example at night for respiration.

Fats and oils

Glucose can as well be converted to fats and oils such as olive oil. Fats and oils are besides used by the constitute every bit a storage form of free energy.

Amino acids

Glucose produced in photosynthesis can be used to help make amino acids. These amino acids are used by the plant to synthesise . Minerals such as nitrate ions are also absorbed by the roots of the plants to help brand these amino acids. Foods such equally peas are good protein sources.
