Determine what the purpose of the root hair is and how does its structure aid it in performing this function?

Root hairs are where most water absorption happens. They are long and so they can penetrate between soil particles, and prevent harmful bacterial organisms from entering the plant through the xylem vessels. They have a large surface area for absorption of water.

Explanation:

The function of root hairs is to collect water and mineral nutrients that are present in the soil and take this solution up through the roots to the rest of the plant. As root hair cells do not carry out photosynthesis, they do not contain chloroplasts. To up take mineral ions and water molecules from the soil, root hair cells have special protein carriers located in their outer membrane. These cells primarily perform the absorption function. These small rectangular structures digest the water and nutrients that are already present in the soil. Absorption. Their elongated, tubular, and pointy structures precisely aid in increasing the exchange of nutrients between the soil and plants' root systems. To up take mineral ions and water molecules from the soil, root hair cells have special protein carriers located in their outer membrane.

Explanation:

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.
