Which three features are specific to plant cells?

The correct choice identifies the cell wall, chloroplasts, and vacuole as features specific to plant cells. Each of these components plays a crucial role in the physiology and functioning of plant cells.

The cell wall is a rigid structure that provides support and protection to plant cells, made primarily of cellulose. This feature is essential for maintaining the plant's shape and enables it to withstand turgor pressure from the inside.

Chloroplasts are the organelles where photosynthesis occurs, allowing plants to convert sunlight into chemical energy in the form of glucose. This process is fundamental to the survival of plants and is why they are essential to many ecosystems.

The vacuole, particularly the large central vacuole found in mature plant cells, serves multiple functions. It is responsible for storing nutrients and waste products, helping maintain cell turgor pressure, and playing a role in plant growth by allowing cells to expand when filled with water.

In contrast, while the other choices present various cellular components, they include features that are not exclusive to plant cells, such as the nucleus and mitochondria, which are found in both plant and animal cells.
