The plant kingdom contains mostly photosynthetic organisms; a few parasitic forms have lost the ability to photosynthesize. The process of photosynthesis uses chlorophyll, which is located in organelles called chloroplasts. Plants possess cell walls containing cellulose.

- Division -Thallophytes. This includes algae. The organisms don’t have a differentiated body(thalloid). They are autotrophic and contain chlorophyll. The algae reproduce by vegetative(fragmentation), asexual(spores), and sexual(gametes) methods.
- Bryophytes. They need both water and soil to complete their life cycle and are knowns as amphibians of the plant kingdom. They may have root-like(rhizoids), leaf-like or stem-like structures.
- Pteridophytes. These are the first terrestrial plants to possess vascular tissues namely the xylem and phloem. These vascular tissues are well differentiated so that each cell can perform its required function.
- Gymnosperms. In gymnosperms, the ovules are naked and are not enclosed within any ovary wall at any point in time. Gymnos stands for naked and sperms mean seeds.
