Roots don't have chloroplasts to make their own food, so they get energy by using sugars that the leaves produce through photosynthesis. The organelles that help root cells convert these sugars into energy are called mitochondria, which act like power plants for the cell.
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. write your answer like a 7th grader

In three to five sentences, explain why animal cells do not require a cell wall or a central vacuole for their functions. write your answer like a 7th grader
Animal cells don't need a cell wall because they have a flexible outer layer called the cell membrane, which allows them to change shape and move around easily. This is important for their functions, like when white blood cells chase bacteria. Animal cells also don't need a central vacuole because they have smaller vacuoles that work together to store nutrients and waste. Instead of having one big storage space, they can use multiple smaller ones to help keep the cell balanced.
In three to five sentences, explain why animal cells do not require a cell wall or a central vacuole for their functions.
Animal cells do not require a cell wall because they have a flexible cell membrane that allows for more movement and shapes, which is important for functions like cell division and mobility. Unlike plant cells, animal cells also do not need a central vacuole for storing water and nutrients, as they have smaller vacuoles that can perform similar tasks. The absence of a rigid cell wall enables animal cells to interact more easily with their environment and allows tissues to form and function properly. Overall, the flexibility and adaptability of animal cells suit their varied roles in the body.
