Botany
Botany generally refers to the study of plants, but other organisms are often included in the field such as photosynthetic bacteria, fungi, algae, and slime molds. Plants are multicellular organisms with complex, eukaryotic cells that contain cell walls, chloroplasts, and other cell structures that are absent in animal cells. They can be studied at many levels, ranging from the molecules that comprise them to cells and tissues to organs to organ systems.
