The life cycle of terrestrial plants includes the alternation of sporophyte and gametophyte generations. Spores are the asexual reproductive cells of mosses and ferns. The multicellular pollen grain is a significantly reduced male gametophyte of seed plants. Palynology is a science that studies pollen and spores of plants, i.e. palynomorphs. It is based on palynological analysis, which includes the isolation of organic microfossils from sediments, the determination of the qualitative and quantitative composition of palynomorphs, and the creation and interpretation of pollen diagrams. Features of palynomorphs that make their analysis informative are: 1. terrestrial plants produce large amounts of pollen and spores 2. The wall of pollen grains and spores contains sporopollenin, a complex polymer due to which palynomorphs can be preserved in sediments when most other (micro)fossils have been decomposed. 3. Pollen and spores can be determined up to a specific systematic level. 4. By analyzing the pollen spectrum from the sediment core, we can visualise the vegetation cover in a certain place at a certain time. Therefore, palynological analysis is useful for understanding plant diversity, reconstruction and changes of vegetation in its composition and structure over time, and reflects the influence of man and climate on changes in plant cover.
