Key points

• is a process that occurs in the leaves of a plant and needs both and lite energy.

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

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

• Carbon dioxide, h2o and light are all needed for photosynthesis to accept place.

What is photosynthesis?

Photosynthesis takes place inside plant cells in modest objects called chloroplasts. Chloroplasts contain a greenish substance chosen chlorophyll. This absorbs the light energy needed to make photosynthesis happen. Plants and algae tin only carry out photosynthesis in the lite.

Plants get carbon dioxide from the air through their leaves, and water from the ground through their roots. Lite energy comes from the Sun.

The oxygen produced is released into the air from the leaves. The glucose produced tin exist turned into other substances, such as starch and found oils, which are used equally an free energy shop. 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's incredibly important. We accept to accept a prophylactic surface and so they're non getting injured, missing a shot, costing your team a chance for a win, the risk for a bays.

I'm Nathan Scarff, and I'1000 the Head Groundsman in Derby County Football Guild.

Working within a stadium, nosotros have a really big shade upshot. The darkest area in this pitch will never run across any sunlight. The plants struggle to photosynthesise naturally, so we use the lights to effectively synthetically induce the photosynthesis process and create the growth, and then it gives the plant a lot of light energy and too some heat as well to encourage growth.

We are looking for just a healthy plant, something that'due south strong, something that'southward durable, something that would recover well.

The sciences that nosotros use is predominately biology, we have a variety of measuring tools, nosotros'll measure the wet, the length of the grass, the hardness of the surface, everything is about producing accented uniformity.

The first year that nosotros had these lights, nosotros won the accolade for all-time pitch in the title. You do take a lot of pride abroad 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 brand past photosynthesis:

• Glucose
• Oxygen

The word equation for photosynthesis in the presence of low-cal and chlorophyll is:

Carbon dioxide + water → glucose + oxygen

Why is photosynthesis important?

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

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

Photosynthesis brings about a balance in the ecosystem as it decreases the concentration of carbon dioxide in the atmosphere. Together with other processes such every bit respiration and , it can help to maintain levels of oxygen and carbon dioxide in the temper.

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

Plant products such as timber, rubber and oil also require photosynthesis to be made.

If a found cannot photosynthesise, it will die

Plants and animals working together

The composition of the atmosphere has inverse since the Earth was formed 4.5 billion years agone. Natural processes, such as photosynthesis, take contributed to maintaining the levels of oxygen and carbon dioxide in the temper, required for survival.

Plants release oxygen into the atmosphere every bit a by-production 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 by 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 action, investigating a unique type of jellyfish

---

Professor Brian Cox: All life depends on the catamenia of energy, which gets passed from one life-form to some other. And there is one beast that embodies more nigh merely how that happens. This is the Golden Jellyfish.

A unique subspecies only plant in this one lake, on this one island, in the tiny Micronesian republic of Palau. Gold Jellyfish have evolved to do something that very few other animals can exercise.' It really is incredible. As far every bit you can see, all the manner down, till the light vanishes, there are jellyfish. And you can see they've congregated in the lord's day. If you go over there, to where the lake's in shade in that location are just none. Then in this pool of calorie-free beneath the dominicus, in that location are millions of them. Beautifully elegant things just floating around.

This lake is home to over xx one thousand thousand jellyfish, whose success comes down to a remarkable accommodation. Their bodies play host to thousands of other organisms. Photosynthetic algae that harvest energy direct from sunlight. And in one case harvested, information technology'due south passed on to the jellyfish to use.

The energy flows from lord's day, to algae, to jellyfish.' The ones at the surface are gently turning and, the reason they do that is to give all their algae an equal dose of sunlight. 'And it's not just their beefcake that's adjusted to harvest solar energy. Every morning time, as the dominicus rises the jellyfish begin to swim towards the east.' And as the lord's day tracks across the heaven, they motion back once more towards the west where they spend their night. So, the jellyfish take this beautiful, intimate, and complex relationship with the position of the sun in the sky. 'Every bit sunlight is captured past their algae it's converted into chemical energy. Free energy they utilise to combine simple molecules, water and carbon dioxide, to produce a far more complex i: glucose. In one case absorbed by the jellyfish, glucose, and other molecules, not but power their daily voyage beyond the lake, they provide the basic edifice blocks the jellyfish utilize to grow the elegant and circuitous structures of their bodies.

So, the jellyfish, through their symbiotic algae, blot the low-cal, the energy, from the lord's day, and they use information technology to, well to alive, to power their processes of life. And that's truthful, directly or indirectly, for every course of life on the surface of our planet. 'The sun's energy that bathes the World is harnessed by photosynthesis.

Once transformed, it'due south passed on from i lifeform to another equally food. The flow of energy animates all living things.

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

The jellyfish motility towards the light of the Lord's day throughout the day to increase photosynthesis. The symbiotic relationship between the two species allows the jellyfish to alive off the glucose the algae produce.

Uses of glucose

Glucose is a useful molecule that is made 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). Call back of it like each glucose molecule being an private bead on a necklace and the entire necklace represents the carbohydrate molecule.

Plants just photosynthesise and glucose during the solar day when at that place is sunlight, just they utilize glucose for respiration all the time, including during the night.

Cellulose

Glucose is used to make cellulose. Cellulose is an case of a natural . Cellulose is the main component found in plant cell walls and this gives the constitute jail cell forcefulness and support.

Humans cannot assimilate cellulose, merely it is important in your nutrition equally fibre. Fibre assists your digestive arrangement, keeping food moving through the gut and pushing waste product out of the body.

Starch

Other uses of glucose produced from photosynthesis is to make the insoluble storage molecule starch. Most plants including rice, potatoes and wheat store their energy equally starch. Starch is also a polymer and tin can be converted back to glucose past the institute when it is needed, for example at night for respiration.

Fats and oils

Glucose can also be converted to fats and oils such as olive oil. Fats and oils are also used past the plant as a storage course of energy.

Amino acids

Glucose produced in photosynthesis can be used to aid make amino acids. These amino acids are used by the plant to synthesise . Minerals such as nitrate ions are as well absorbed by the roots of the plants to assist make these amino acids. Foods such every bit peas are good protein sources.
