1. Cell wall: Plant cells have a rigid cell wall made of cellulose, which provides structural support and protection for the cell. This feature is unique to plant cells and is not found in other eukaryotic organisms.
2. Chloroplasts: Plant cells contain chloroplasts, which are organelles that carry out photosynthesis. Chloroplasts contain chlorophyll, a pigment that captures sunlight and converts it into energy. This feature is also unique to plant cells and is not found in other eukaryotic organisms.
3. Large central vacuole: Plant cells have a large central vacuole that stores water, nutrients, and waste products. This vacuole helps maintain turgor pressure, which is important for plant structure and support. Other eukaryotic organisms may have vacuoles, but they are typically smaller and less prominent than those found in plant cells.
4. Plasmodesmata: Plant cells have structures called plasmodesmata, which are channels that allow for communication and transport of materials between adjacent plant cells. This feature is unique to plant cells and is not found in other eukaryotic organisms.
5. Starch storage: Plant cells store energy in the form of starch, which is a polysaccharide made up of glucose molecules. Starch granules can be found in the chloroplasts and amyloplasts of plant cells, providing a long-term energy reserve. Other eukaryotic organisms may store energy in the form of glycogen or fat, but not starch.

Cell Wall:
- Plant cells possess a rigid cell wall made of cellulose and other complex carbohydrates.
- The cell wall provides structural support, protection, and rigidity to the plant cell.
Chloroplasts:
- Chloroplasts are organelles responsible for photosynthesis.
- They contain chlorophyll, a green pigment that absorbs sunlight and uses it to convert water and carbon dioxide into glucose (sugar).
Vacuole:
- Plant cells have a large central vacuole that occupies up to 90% of their volume.
- The vacuole contains water, storage molecules, and metabolic waste products.
Plasmodesmata:
- Plasmodesmata are channels that connect the cell wall and cytoplasm of adjacent plant cells.
- They allow for the exchange of nutrients, molecules, and signals between cells.
Plastids:
- Plastids are organelles involved in various functions, including:
- Chloroplasts (for photosynthesis)
- Chromoplasts (for color storage)
- Amyloplasts (for starch storage)
Turgor Pressure:
- The large vacuole and cell wall create a condition known as turgor pressure.
- Turgor pressure provides firmness to the plant cell and aids in water balance.
Absence of Centrioles:
- Unlike animal cells, plant cells do not contain centrioles, which are involved in cell division.
- Instead, plant cells have a microtubule-based spindle apparatus that facilitates cell division.
