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. in two sentence
Root cells obtain energy through the process of cellular respiration, which occurs in the mitochondria. Through this process, root cells break down glucose and convert it into ATP, the main energy molecule used by cells.

Root cells derive energy through cellular respiration, a process that takes place primarily in mitochondria. Mitochondria break down glucose and convert it into ATP, the main energy currency for cells.
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 rely on other structures for support and protection. The presence of an extracellular matrix made up of proteins, along with the cell's cytoskeleton, provides support and maintains cell shape. Animal cells also do not possess a central vacuole because they have smaller, scattered vacuoles that perform specific functions like storing nutrients, maintaining turgor pressure, or removing waste products, which are sufficient for their needs. Additionally, animal cells have developed other adaptations, such as cell-to-cell junctions, to enable cell adhesion and communication.
In three to five sentences, compare the process of digesting food in an amoeba (unicellular) to those in a mouse (multicellular) .
The process of digesting food in an amoeba, a unicellular organism, involves phagocytosis. The amoeba engulfs its food through its cell membrane, forming a food vacuole that fuses with lysosomes to digest the food. In contrast, a mouse, a multicellular organism, has a more complex digestive system. It ingests food through its mouth, where it is mechanically broken down by chewing, and then swallowed into the stomach. Enzymes and acids in the stomach further break down the food, which then moves to the small intestine where nutrients are absorbed into the bloodstream for distribution to other cells in the body.
