Plant cell
The
cellss of
plants are quite different from the cells of most other organisms. Their unique features are:
- A large vacuole (the tonoplast), used to maintain cell turgor;
- A cell wall made up of cellulose and protein, and in many cases lignin and deposited by the protoplast on the outside of the cell membrane;
- Chloroplasts, a type of plastid that contains chlorophyll.
Like other eucaryotic cells, plant cells typically also have a
nucleus.
Types of Plant Cells
- Parenchyma ~ ground tissues
- Chlorenchyma ~ photosynthesis
- Collenchyma ~ support
- Sclerenchyma ~ fibers
- Epidermal ~ surface covering
- Cork
- Tracheid ~ support
- Vessel ~ elements
- Meristematic ~ growth
