Photosynthesis

This category is for questions about the chemical process in which autotrophic organisms use sunlight, carbon dioxide and water to make glucose, water and oxygen. This process is vital to life and is of great importance in biology.

What structure on the underside of the leaf allows the leaf to breathe or transpire?

Stomata are tiny pores on the underside of leaves that allow for gas exchange during photosynthesis. This structure also facilitates the transpiration process, through which plants release water vapor.

What and how do organisms use sunlight energy trapped in plants?

This energy is stored in glucose. Plants synthesize many things using glucose energy. Other organisms consume plants basically

What are three molecules that go into the Calvin cycle?

Dear friend, in Calvin cycle only two kinds of trioses (3C sugars) are formed. In fact, these are not sugars but phospoesters. One is phospoglyceraldehyde and second is dihydroxyacetone phosphate. These are isomers of each other.

How do photosynthesis affect snakehead fish?

Photosynthesis is a chemical process that occurs in plants. It uses energy from the sun to combine carbon dioxide and water to produce sugar and oxygen. It is of no relevance to snakehead fishes.

The central vein seen in the blade of a leaf is called the bundle sheath?

The central vein seen in the blade of a leaf is called the midvein or midrib. The bundle sheath is a layer of cells surrounding the vascular bundles in certain types of plant leaves, like in C4 plants. It is involved in the transport of water and nutrients within the leaf.

How is smart water produced?

well actually yes smart water does make you very smart because i took a big test did not know a thing on it and drunk a smart water and passed it with a one hundred and i was so thankful for that wonderful water and would love to enjoy another one some time.

In each theory what causes the extinction of plants and animals?

Asteroid Impact : Plants and organisms that performed photosynthesis died, and many animals that depended on those plants for food died, too

Volcanic Eruptions : The volcanic dust blocked the sun's energy from reaching Earth's surface, causing plants, and animals to die.

Where are PSI and PSII located?

Photosystem I (PSI) and Photosystem II (PSII) are located in the thylakoid membranes of chloroplasts in plant cells. PSII is situated at the beginning of the photosynthetic electron transport chain, while PSI is located further along the chain. Both systems play crucial roles in the light-dependent reactions of photosynthesis, facilitating the conversion of light energy into chemical energy.

What is the name of the leaf structure in which plants trap solar energy?

It is not just in leaves, any part of a plant that is colored green does this.

Plants use a chemical called chlorophyll to perform photosynthesis, converting the energy of the photons in sunlight into glucose molecules and waste oxygen.

How do the products of photosynthesis help cellular respiration occur?

Cellular respiration is using glucose. The main product of photosynthesis.

What are the most effective means to fight hemeralopia - inability to see in dim or faint light?

People who suffer from hemeralopia actually see better in faint or dim light than they do in bright light. That's why another term for the condition is "day blindness." It's the opposite of night blindness. With hemeralopia, seeing in bright light (or even normal sunlight) can be painful and/or cloudy. The most effective means of fighting hemeralopia depend on what's causing it, and it can be caused by a variety of factors. Some people with uveitis suffer from hemeralopia, as do some people with complications from laser eye surgery. Some medications can cause light sensitivity as a side effect. Sunglasses work for some people but not for others. The best course of action is to see a qualified eye doctor. A clarification -- hemeralopia literally means "day blindness"; nyctalopia is the word for "night blindness". The two words have fallen more or less out of use because they're confusing. If you run an internet search on hemeralopia, for instance, you'll find a lot of sites where it's defined as the inability to see clearly in bright light -- but you'll also find sites where it's defined as the inability to see clearly EXCEPT IN bright light. The same thing happens with nyctalopia and darkness. So it seems that most people just use the terms "day blindness" (trouble seeing in bright light) and "night blindness" (trouble seeing in darkness).

What substance provides oxygen produced during photosynthesis?

Water, of course. Water undergoes photolysis in photosystem II and oxygen is a byproduct that is diffused out of leaves.

What kind of organisms use cellular restpiration?

All of them do except for ones that instead use fermentation
