The correct answer would be plasma membrane.
ok
Since the cell is incapable of producing its own food, it would not have chloroplasts, which are responsible for photosynthesis. However, it would still require a plasma membrane to control the passage of substances in and out of the cell. Additionally, depending on the type of cell, it may also require a cell wall for support and protection. Therefore, the organelles that the cell must have are the plasma membrane and potentially the cell wall.
To determine which organelle a round cell incapable of producing its own food must have, we can eliminate options based on the characteristics given.
1. Plasma membrane: The plasma membrane is present in all cells and is responsible for regulating the passage of substances in and out of the cell. However, it does not play a direct role in food production. So, this cannot be the organelle we are looking for.
2. Central vacuole: While the central vacuole is a large storage compartment found in many plant cells, it is not directly involved in food production. It mainly functions in storing water, nutrients, and waste products. Therefore, this is not the organelle described in the question.
3. Cell wall: The cell wall is a rigid outer layer that provides support and protection to the cell. In plant cells, the cell wall is composed mainly of cellulose. Although the cell wall is required by plant cells, it does not directly relate to the cell's ability to produce food. Thus, it is not the answer we are looking for.
4. Chloroplast: Chloroplasts are organelles found in plant cells that have the ability to capture sunlight and carry out photosynthesis. During photosynthesis, chloroplasts convert light energy into chemical energy (food) in the form of glucose. Since the question states that the cell cannot produce its own food, it indicates that the cell lacks chloroplasts. Therefore, this is the correct answer.
From the given options, the organelle the cell must have is the plasma membrane. However, it is important to note that this organelle is present in all cells and does not specifically address the cell's inability to produce food.
