Of the following experimental results, which is the best evidence that photosynthesis is more efficient at certain wavelengths o
GarryVolchara [31]

Answer:

The correct answer will be option-C

Explanation:

The plant absorbs the sunlight to perform photosynthesis which helps produce the sugar molecule used by the plants.

The plants absorb maximum sunlight at two wavelengths that are red and blue wavelength by chlorophyll and other pigments. The efficiency of photosynthesis is also measured maximum at these two active wavelengths called action spectrum.

In the given question, since the efficiency of photosynthesis has been discussed which could be measured with the production of oxygen and consumption of carbon dioxide. The experiment performed by the Engelmann showed that aerobic bacteria got concentrated in the blue and red wavelengths as the output of the photosynthesis were observed maximum.

Thus, the selected option is the correct answer.

which structure in leaves allows the gaseous reactants and products of photosynthesis to move in and out a b c d
Zepler [3.9K]

Answer:

Stomata

Explanation:

Photosynthesis is a unique phenomenon which occurs in the Chloroplast of plant cells. It is the way they synthesize their food in form of glucose. However, like every metabolic reaction, photosynthesis requires certain reactants and products.

Photosynthesis combines carbondioxide (CO2) gas and water (H2O) in the presence of sunlight to produce Glucose (C6H12O6) and oxygen gas (O2). The gaseous components of this metabolic activity enters (C02) and leaves (O2) the plant via a structure in the leaves called STOMATA.

STOMATA is a pore found in the epidermis layer of plant leaves that aids in the exchange of gases i.e. carbondioxide in, oxygen out during Photosynthesis.

In the central dogma, the rna-to-protein step is termed.
Zarrin [17]

Answer:

translation

Explanation:

a process called translation uses this mRNA as a template for protein assembly. In fact, this flow of information from DNA to RNA and finally to protein is considered the central dogma of genetics, and it is the starting point for understanding the function of the genetic information in DNA.
