Detailed explanation-1: -Presence of a cell wall: The cell wall offers rigidity to the plant cells. Presence of large vacuoles: The large vacuole cover a major part of the cytoplasm and it increases with aging of the cells.

Detailed explanation-2: -The main function of the central vacuole is to maintain turgor pressure in the cell. Turgor pressure is the pressure of the cell’s contents pushing against the cell wall; it is only found in cells that have cell walls, such as those of plants, fungi, and bacteria.

Detailed explanation-3: -Plastids are present only in plant cells. These are chloroplasts, chromoplasts and leucoplasts. They help in pigmentation of the cells.

Detailed explanation-4: -Plant cells have certain distinguishing features, including chloroplasts, cell walls, and intracellular vacuoles.

Detailed explanation-5: -Most mature plant cells have a central vacuole that occupies more than 30% of the cell’s volume. The central vacuole can occupy as much as 90% of the volume of certain cells. The central vacuole is surrounded by a membrane called the tonoplast.
