Explain the following terms:
$(a)$ Phanerogams
$(b)$ Symbiosis
$(c)$ Binomial Nomenclature

(N/A) Phanerogams: These are plants with well-differentiated reproductive tissues that ultimately produce seeds. They are also known as seed-bearing plants.
$(b)$ Symbiosis: It is a permanent,mutually dependent relationship between two organisms in which both partners benefit. For example,the association between certain fungal species and blue-green algae (or cyanobacteria) forms lichens.
$(c)$ Binomial Nomenclature: This is a system of naming organisms using two words: the first word represents the generic name (genus) and the second word represents the specific epithet (species).
