Answer #1

Phytochrome becomes active in

Answer is (a) red light

Explanation :-

Phytochrome are photoreceptor present in plants which are used to detect light.

- They are sensitive to light in red and far-red region of visible spectrum.

They are sensitive to red and far-red light.

They are classified as type-I and type-II.

Type-I are activated by far-red light and type-II are activated by red light.

So phytochrome becomes active in red light.

Hope you got your answer.

A current is detected in a photoelectric-effect experiment when the cathode is illuminated with green light. Part A Will a current necessarily be detected if the cathode is illuminated with blue light? Select the correct answer and explanation. (1)Photons of blue light have less energy than photons of green light. Therefore, if there is a current in a photoelectric-effect apparatus with green light, then there could be no current with blue light. (2)Photons of blue light have less energy than...

Red, Blue and Green are three genes found on the same chromosome. Each gene has two alleles: R or r, B and b, and G and g, respectively. The somatic cells and gametes of a person that is heterozygous for the alleles of all three genes are studied to understand the relationships between the three genes. It is found that the dominant alleles for Red and Green is on the person’s paternal chromosome, but the dominant allele for Blue is...
