To determine which of the given materials would not be important to a protozoan, we need to understand the basic needs of protozoa.
Protozoa are single-celled organisms that exhibit various methods of obtaining energy and nutrients. They require certain materials for their survival and functioning. Let's evaluate each option:
a) Enzymes: Enzymes are crucial for catalyzing the biochemical reactions within protozoa. They help in various processes like digestion, respiration, and reproduction. Therefore, enzymes are important to a protozoan.
b) Oxygen: Most protozoa are aerobic, meaning they require oxygen for the process of respiration to produce energy. Oxygen is essential for the survival of protozoa; hence, it is important to them.
c) Water: Water is essential for all forms of life, including protozoa. They require water for various physiological processes, such as cell metabolism, nutrient uptake, and waste removal. Therefore, water is important to a protozoan.
d) Blood: Protozoa do not have a circulatory system, so they do not rely on blood as a material necessary for their survival. Therefore, blood is not important to a protozoan.
e) Carbohydrates: Carbohydrates serve as a primary source of energy for protozoa. They are broken down through enzymatic reactions to release energy. Hence, carbohydrates are important to a protozoan.
Based on the above analysis, we can conclude that the material that would not be important to a protozoan is d) blood.
