- Plant cells are the basic unit of life in organisms of the kingdom Plantae. They are eukaryotic cells, which have a true nucleus along with specialized structures called organelles that carry out different functions. Plant cells have special organelles called chloroplasts, which create sugars via photosynthesis.

- Cell Wall. It is the outermost, protective layer of a plant cell having a thickness of 20-80 nm. Cell walls are made up of carbohydrates such as cellulose, hemicellulose, and pectin and a complex organic polymer called lignin.
- Plastids. They are double membrane-bound organelles that have their own genetic material. Plastids are mainly of three types: a) Chloroplasts: Found in the green parts of a plant and algae that contain the photosynthetic pigment, chlorophyll.
- Central Vacuole. It is the large vesicle that make up almost 30 to 80% of the total plant cell volume. The central vacuole is often the largest organelle in the cell that is filled with fluid, ions, enzymes, and other molecules.
- Cell Membrane or Plasma Membrane. It is a thin, biological membrane having a thickness of 7.5-10 nm that separates the interior of the cell from the outside environment.
Plant cells differentiate from undifferentiated meristematic cells (analogous to the stem cells of animals) to form the major classes of cells and tissues of roots, stems, leaves, flowers, and reproductive structures, each of which may be composed of several cell types.
May 17, 2023 · A plant cell is the basic building block of a plant. Plant cells, like all eukaryotic cells, contain a nucleus and other organelles, each with its distinct functions. However, plant cells also possess unique components that differentiate them from animal, fungal, and bacterial cells.
