Question

A student is observing a single-celled alga and knows that it undergoes photosynthesis and respiration. Which question could the student ask to find out how it can do both processes?

Answer 1

The options associated with the question is :

Are the inputs of photosynthesis the same as the outputs of respiration?

Are the inputs of photosynthesis the same as the inputs of respiration?

Is water needed for the processes of respiration and photosynthesis?

Is carbon dioxide needed for the process of photosynthesis?

Answer:

The correct answer is - Are the inputs of photosynthesis the same as the outputs of respiration?

Step-by-step explanation:

To understand that it is able to perform both the process photosynthesis and cellular respiration by this single cell of alga it is required to understand the process of both processes and how they provided to the alga.

Photosynthesis is the process that converts water and carbon dioxide into glucose and oxygen as the output or products. Glucose is further used in the cellular respiration with oxygen to produce water and carbon dioxide. So it make balance of the inputs and outputs in the both reaction so it can be understand by asking if the inputs of photosynthesis the same as the outputs of respiration?

Answer 2

Photosynthesis and respiration both are shown by algae because they need light to make food.

Algae are a diverse group of predominantly photosynthetic organisms, including cyanobacteria, green algae, and other eukaryotes. They account for more than 50% of the photosynthesis that occurs on Earth. Photosynthetic efficiency is higher in algae than in higher plants. Algae use carbon dioxide for cellular respiration. It binds CO2 and reduces the amount in the atmosphere.

The questions which students can ask are :

Are the inputs to photosynthesis and the outputs to respiration the same?

Are the photosynthesis and respiration inputs the same thing?

Is it true that water is required for respiration and photosynthesis?

Is carbon dioxide required for photosynthesis?

what are algae?

A group of photosynthetic, aquatic, marine, true root stems leaves bearing organisms.

thus it concludes algae can perform both cellular respiration and photosynthesis.
