Question

a scientist is examining a slide of pond water. she finds an organism that creates glucose in the presence of light, reproduces, requires co₂ to survive, is single - celled, and is motile with the use of flagellum. which of these characteristics gives evidence that this organism fits into the modern cell theory? (sc912l14.1) a. creates glucose in the presence of light b. requires co₂ to survive c. is motile with the use of flagellum d. is composed of one cell

Explanation:

Modern cell theory states that all living organisms are composed of one or more cells. The organism described creates glucose in the presence of light (photosynthesis), requires CO₂ to survive, is single - celled, and is motile. All these characteristics are consistent with what is known about single - celled photosynthetic organisms which fit into the framework of modern cell theory. Each option is analyzed based on cell theory principles. Option A (creates glucose in the presence of light) shows it is capable of photosynthesis which is a characteristic of many single - celled organisms. Option B (requires CO₂ to survive) is typical for photosynthetic organisms. Option C (is motile with the use of flagellum) and Option D (is composed of one cell) also support its classification within modern cell theory. But the most fundamental aspect of cell theory is that organisms are made of cells, and the fact that it is single - celled is a key characteristic.

Answer:

D. Is composed of one cell
