Photosynthesis Questions and Answers (Q&A)

The correct answer to this question is option B
Calvin cycle, also known as Benson Calvin cycle refers to series of chemical reactions that take place in the chloroplast of a plant during photosynthesis.

The cycle has four main steps that are light dependent. These steps are: carbon fixation, reduction phase, carbohydrate formation, and regeneration phase.

The energy required to carry out these chemical reactions is supplied by ATP and NADPH. This cycle is light dependent as it takes place after the energy has been captured from sunlight.
The products of Calvin cycle are: Carbohydrate, NADP+ and ADP.
Hope this helps.

A carrot is an example of a taproot system because a taproot has a single straight, vertical root that grows very deeply and smaller, horizontal roots grow off of this root. Therefore, the answer is A. Other taproot plants include parsley, turnips, and common milkweed.

Notice that all four of these examples are foods or could be used as food. That’s because some taproot systems are so well defined after all this time that they develop in large enough quantities to be eaten.

That said, the word “taproot” can also refer to a band called Taproot (which produces metal and alternative rock music) or the Taproot Foundation. The Taproot Foundation is a pro bono marketing, design, and other services foundation that encourages giving these services out.

The oxygen during photosynthesis comes from split water molecules. During photosynthesis, the plant absorbs water and carbon dioxide. After the absorption, the water molecules are disassembled and converted into sugar and oxygen. The water molecules are also split into oxygen and hydrogen and the latter (hydrogen) is joined to the carbon dioxide to create sugars. Excess oxygen gathered after all these are released into the atmosphere during respiration.

In another regard, plants take in carbon dioxide (CO2) and water (H2O) during photosynthesis. The Chlorophyll in the leaves absorb sunlight and the water and carbon dioxide are used for making sugar. This sugar is stored for energy. Excess sugar is left behind in the root to work as starch and the excess water and carbon dioxide will evaporate.

You don’t need oxygen but you do need sunlight to process photosynthesis. Whoever did this question is DUMB!

The correct answer is option C
Xylem is the plant tissue that carries water; it is one of the transport systems present in a plant. Xylem transports water and soluble minerals from roots to other parts of the plant. It is also responsible for replacing water lost during transpiration and photosynthesis
Stomata are pores found in the epidermis of leaves and stems that facilitate gas exchange.

Chlorophyll is a green pigment found in plants and algae. It plays a vital role of absorbing energy in photosynthesis.

Phloem is the second transport system in a plant. It helps transport food (sugars and amino acids) made by photosynthetic areas to other areas and also to storage structures such as the root, bulbs or tubers.

The second half of this equation is “6H2O + 6CO2 + ATP”. However, photosynthesis to respiration would read “6CO2 + 6H2O + LIGHT ---> C6H12O6 + 6O2 ---> 6H2O + 6CO2 + ATP”. Every living thing does the cellular respiration part (from C6H12O6 forward). However, only plants do the first part with light, which we call photosynthesis. It’s actually pretty incredible; plants take our waste - CO2, or carbon dioxide - and light, add some water, and create their own sugar.
Cellular respiration creates ATP through something called the Krebs Cycle. This is a complex cycle, and takes a little more time to explain.

However, it does create between 30 and 34 molecules of ATP. This is because it makes the electrons work by going through an electron chain, and when the electron is done, it’s attached to the molecules that become water.

Glucose is formed in the Calvin Cycle not the light reactions. NADPH is required.
