It is worth noting such a discipline as plant morphology. This science studies the structure of plants.

It is subdivided into:

Microscopic morphology. It studies the structure of cells and tissues of plants, embryology;
Macroscopic morphology (organography). It studies the organs and parts of plants.

Sections of morphology
Individual sections of morphology are disciplines in their own right:

Organography. Studies the organs and parts of plants;
Palynology. The subject of its study is the structure of plant spores and pollen;
Carpology. Classifies fruits;
Teratology. Investigates deformities and anomalies arising in the structure of plants;
Plant Anatomy. Studies how plants are arranged internally;
Plant Physiology. It deals with the study of plant forms observed during ontogenesis and phylogenesis and the processes that occur in the plant: their causes, characteristics, and relationship to the environment. Physiology is concerned with systematics;
Plant biochemistry. It is interested in the chemical processes that occur in plants – those associated with growth and development;
Plant genetics. It is concerned with genetic changes in plants. It does not matter whether they occur without or with human intervention;
Phytocenology. Studies the vegetation of the planet, notes the dynamic changes in nature, the dependencies and patterns of these changes;

Vegetation in this context is the combination of all plants in one area that make up its landscape.

Geobotany. Concentrates on the study of ecosystems: the relationship between plants, animals, and non-living nature (this complex is called biogeocenosis);
Plant ecology. It focuses on plants and their habitat, as well as determining the most appropriate conditions for plant life;
Paleobotany. It focuses on the study of fossil plants, which provides an opportunity to trace the history of development.

Classifications of botany by object of study
If we distinguish the individual sciences in botany briefly, it turns out that by the object of study this classification includes:

Algology. This is the science of algae;
bryology. It studies mosses, etc;
microbiology. Studies microscopic organisms;
phytopathology. Its field of study is plant diseases caused by bacteria, viruses, and fungi.

If the residence of the object under study is taken into account, then we can talk about special branches in plant botany. Among them – forest science, marsh science, meadow science, tundra science, etc.

The science of botany also studies mushrooms. There is a separate discipline for this study, mycology, which appeared when fungi were put into a separate kingdom.
