What factors limit photosynthesis

The environmental factors affecting the process of photosynthesis follow the law of limiting factor as hypothesized by the British plant physiologist F.

Anoxia will hit the crew when the atmospheric pressure drops to what pressure? From Living In Space by G. Artwork by Rick Sternbach. Low pressure is attractive; since it uses less mass and the atmosphere will escape more slowly through a meteor hole.

Unfortunately the required higher oxygen level make living in such an environment as hazardous as chain-smoking inside a napalm factory. NASA found that out the hard way in the Apollo 1 tragedy.

Since then NASA always uses high pressure, they use low pressure in space suits What factors limit photosynthesis because they cannot avoid it. This does raise a new problem. There is a chance that the high-oxygen atmosphere will allow a meteor to ignite a fire inside the suit. There isn't a lot of research on this, but NASA seems to think that the main hazard is a fire enlarging the diameter of the breach, not an astronaut-shaped ball of flame.

There are other problems as well, the impossibility of air-cooling electronic components and the risk of long-term health problems being two.

15 Main Factors Affecting Photosynthesis

Setting up the optimal breathable atmosphere is complicated. A more annoying than serious problem with low pressure atmospheres is the fact that they preclude hot beverages and soups.

It is impossible to heat water to a temperature higher than the local boiling point. And the lower the pressure, the lower the boiling point. You may have seen references to this in the directions on certain packaged foods, the "high altitude" directions.

The temperature can be increased if one uses a pressure cooker, but safety inspectors might ask if it is worth having a potentially explosive device onboard a spacecraft just so you can have hot coffee. Human-breathable mixtures of oxygen and nitrogen as a function of barometric pressure the blue area.

Below inspired partical pressure pO2 60 mm Hg you suffer hypoxiaabove pO2 mm Hg you suffer oxygen toxicityabove pN2 mm Hg nitrogen narcosis From Habitable Planets for Manmodifed by me.

The Bends prebreathing Decompression sickness also known as DCS, divers' disease, the bends or caisson disease is one of the more hideous dangers of living in space. It occurs when a person has been breathing an atmosphere containing inert gases generally nitrogen or helium and they move into an environment with lower pressure.

This is commonly when they put on a soft space suit or the room suffers an explosive decompression. It has all sorts of nasty effects, ranging from joint pain and rashes to paralysis and death.

The large joints can suffer deep pain from mild to excruciating. The brain can have sudden mood or behavior changes, confusion, memory loss, hallucinations, seizures, and unconsciousness.

The legs can become paralyzed.

What are the Factors that affect Photosynthesis

Headache, fatigue, malaise, loss of balance, vertigo, dizziness, nausea, vomiting, hearing loss, shortness of breath, and urinary or fecal incontinence: Why does it happen?

Well, imagine a can of your favorite carbonated soda beverage. Shake it up, and nothing happens. But when you open it, the soda explodes into foam and sprays everywhere. When you open the container of shaken soda, you lower the pressure on the soda fluid. This allows all the dissolved carbon dioxide in the soda to un-dissolve, creating zillions of carbon dioxide bubbles, forming a foam.

Requirements

Now imagine that the carbon dioxide is nitrogen, the drink is the poor astronaut's blood in their circulatory system, and the foam is the deadly arterial gas embolisms.

That's what causes the bends.Antioxidant activity. In plants, carotenoids have the important antioxidant function of quenching (deactivating) singlet oxygen, an oxidant formed during r-bridal.com tube studies indicated that lycopene is one of the most effective quenchers of singlet oxygen among r-bridal.com also suggested that carotenoids could inhibit the oxidation of fats (i.e., lipid peroxidation) under.

The main variables which affect photosynthesis are light, water, CO 2 concentration and temperature.. On a deeper level, other factors like amount of chlorophyll, availability of nutrients (eg Mg is needed for chlorophyll synthesis) will also affect the rate of photosynthesis, though these are .

In NASA-speak: ECLSS Environmental Control And Life Support r-bridal.com part of your spacecraft or space station that makes a livable environment so the astronauts don't .

There are a number of factors that interact to make the process of photosynthesis work. Any one of these could become a limiting factor, in Which Water can be considered too. The Limiting Factors in Photosynthesis are * Amount of the intensity of.

B The effect of carbon dioxide

The factors of photosynthesis all occur simultaneously. However, the factor that is present at the least favourable level is the one that limits the process. Analogy: think of it like this, if you were making a cake and had lots of flour, sugar and butter but only three eggs, you'd have to limit the cake's size because of the limited amount of.
