Question

Scientist claims that Elysia chlorotica, a species of Sea slug, is capable of photosynthesis. which of the following observations provides the best evidence to support the claim?
A) Elysia chlorotica will die if not exposed to light
B) Elysia Chlorotica grows when exposed to light in the absence of other food sources
C) Elysia chlorotica grows faster when exposed to light than when placed in the dark
D) Elysia chlorotica grows in the dark when food sources are available.

Answer 1

Answer:

The correct answer is - B) Elysia Chlorotica grows when exposed to light in the absence of other food sources

Explanation:

If placing Elysia Chlorotica in presence of the food sources in the presence or absence of light it still grows as normal. However, if placing in the light in absence of the food sources it should not grow if it is not able to perform photosynthesis but it does which means there is a photosynthesis process also involve in the Elysia.

Photosynthesis is the process that involves the production of energy and nutrition in presence of light with water and atmospheric carbon dioxide.

Answer 2

Elysia chlorotica is a mollusc that belongs to the species of green slugs. It is generally found in the coastal zones of the United States including New Jersey, New York, Texas and Florida.

The correct answer is:

Option B) Elysia Chlorotica grows when exposed to light in the absence of other food sources.

The explanation for the option is:

• Some of the chloroplasts are stored in the digestive system, which sustains and keeps them alive for months for later use.

• After some years these chloroplasts get deeply buried in the cells of the gut facilitating the slugs to remain green without feeding further.

• This merger of mitochondria into the cells enables the slugs to capture the energy and allows them to make their food just like plant makes food from the process of photosynthesis.

Therefore, Elysia Chlorotica grows when exposed to light in the absence of other food sources as it makes its own food and energy.
