Question

Scientists on another planet have made an exciting discovery about a new photosynthetic plant. The plant appears black instead of green. What does the plant’s color tell you about its photosynthesis?

Answer 1

Answer:

The correct answer would be - the new photosynthetic plant has black pigment instead of green pigment as the plants on earth has,

Explanation:

Chlorophyll is the pigment that absorbs the light come from the sun and utilize it for the process of the photosynthesis with the help of the other components. Plants of the earth are normally green as the chlorophyll are green in color.

Similarly if the photosynthetic plant of another plant is black that means it has black pigment that absorbs light for the photosynthetic process instead of green as chlorophyll.

Thus, the correct answer is - It has black pigment instead of green.

If a plant has a black pigmentation instead of a green pigmentation it will absorb more energy because black absorbs more energy than green.

Answer 2

Answer:

The pigment present in these plants must be able to absorb the whole spectrum of visible light.

Explanation:

Green plants appear green since chlorophyll pigment does not absorb the green part of the visible light. This light is reflected back to our eyes and the leaves having chlorophyll appear green. If the plants from the new planet appear green, this means that the pigments present in these plants are able to absorb the whole visible light as a source of energy for photosynthesis. Therefore, these plants are better in the absorption of the energy for photosynthesis.
