Palynological Features used in Plant Systematics
Palynological characters have been used in solving several taxonomic problems, including the repositioning of deveral disputed taxa, and interpretation of problems relating to the origin and evolution of different groups. Palynology is used in phylogenetic analysis. It can be utilised in plant identification of extant plants and fossil plants. In fossil plants we study about paleopalynology/paleobotany and about the past plant communities, climate, biogeography, migration. In pollen characteristics of systematic values we will discuss pollen aggregation. Microsporogenesis equals four microspores which match were into four pollen greens. In majority of angiosperms the pollen grains separate prior to release such a pollen grains is known as monoders in rare cases pollen grains are released as fused in the form of fears.

- Pollen storage product
- Pollen unit
- Pollen polarity
- Pollen aperture
- Pollen size
- Pollen shape
- Pollen sculpturing
- Pollen wall structure
Palynology – Definition, Description & Applications
Palynology is an important branch of botanical science. It is derived from the word palynos-dust. We study the palynology in paleobotany. In palynology, we study and research the different types of pollen grains, spores, and other palynomorphs of the many plant species found in different parts of the world. We also study the shape, structure, functions, chemical structure, and components of pollens in plants.
Palynology also helps in studying and identifying dust particles. It is mainly responsible for the extraction of fossils. In pollens, we have two types of layers one is intine (the inner part) and another is exine (the outer part). The exine is made up of the material sporopollenin. Sporopollenin is a ubiquitous and extremely chemically inert biopolymer that constitutes the outer wall of all land-plant spores and pollen grains.
