Final answer:
In a muscle cell, you would expect to see a nucleus and mitochondria because they are essential for cell control and energy production. Muscle cells do not have chloroplasts or a cell wall, which are specific to plant cells.
Step-by-step explanation:
In a muscle cell, you would expect to see a nucleus, which contains the genetic material necessary for controlling cell activities. Additionally, mitochondria are crucial for muscle cells as they are the powerhouses that produce ATP (adenosine triphosphate), which is used for muscle contraction. Muscle cells also have a plasma membrane but do not have a cell wall, which is a feature specific to plant cells. Chloroplasts are also specific to plant cells and are involved in photosynthesis, a process not pertinent to muscle cells. Therefore, the correct items that you would expect to see in a muscle cell are a nucleus and mitochondria.
