The setup shows four test tubes. Tube 1 contains water only. Tube 2 contains a live snail. Tube 3 contains a live green water plant. Tube 4 contains both a live green water plant and a live snail. We know that plants can photosynthesize. We also know the product of photosynthesis is the reactant of cellular respiration. In this setup, which tubes contains and organism(s) carrying on cellular respiration?

a) tubes 2 and 4, only

b) tubes 3 and 4, only

c) tubes 2, 3, and 4 only

d) tubes 1 and 2, only

pls help as fast as u can! <3

c) tubes 2, 3, and 4 only

Explanation:

Cellular respiration is a metabolic process in which cells of living organisms break down organic molecules to synthesize or release energy in form of ATP. Because all cells require or need energy (ATP) for their functioning, cellular respiration is carried out by ALL LIVING ORGANISMS.

According to this question involving four test tubes that contain the following:

- Tube 1 contains water only.

- Tube 2 contains a live snail.

- Tube 3 contains a live green water plant.

- Tube 4 contains both a live green water plant and a live snail.

Cellular respiration will be carried out in the test tube that contains any living organisms. These test tubes are test tubes 2, 3 and 4 as they contain live green plants and snail.
