Question
Chloroplasts play an important role in energy production in plant cells. However, some parts of a plant, like the roots, lack chloroplasts. In one to two sentences, explain the most likely pathway for root cells to obtain energy, and identify the organelles involved.

The most likely pathway for root cells to obtain energy is through the process of cellular respiration, which occurs in the mitochondria. This process converts nutrients into ATP, the main energy source for cells.

simplify into a students answer

Root cells obtain energy through cellular respiration in the mitochondria.

whats celluar respitation

Cellular respiration is the process by which cells convert nutrients, such as glucose, into usable energy in the form of ATP (adenosine triphosphate). It occurs in the mitochondria of cells and is essential for their survival and function.

Study the images provided. Select one of the organisms. Identify whether the organism is unicellular or multicellular and explain how that affects the way that its cells are able to perform the life functions needed for survival. To earn full credit on this question you must use vocabulary and concepts presented in this unit and write in complete sentences. Your response should be between 1 and 3 sentences 

To answer this question, we need to understand that chloroplasts are responsible for energy production through photosynthesis, which primarily occurs in the leaves of a plant. Since roots lack chloroplasts, they cannot directly produce energy through photosynthesis. Instead, root cells obtain energy by breaking down carbohydrates and other organic molecules produced in the leaves and transported to the roots through the vascular tissue. The organelles involved in this process are mitochondria, which are responsible for cellular respiration that generates energy from the breakdown of these organic molecules.
