Pictorial Feature of Plant Kingdom

Kingdom Fungi

• It includes eukaryotes with cell wall (made of chitin), which have heterotrophic mode of nutrition. 

• They may be saprophytic, parasitic, or symbiotic.

• Their body consists of long slender thread-like structures called hyphae. The network of hyphae is called mycelium. 

• The symbiotic association of fungi and algae is known as lichens. 

• The fungi living in symbiotic association with roots of higher plants are known as mycorrhiza.

• Fungi reproduce asexually through spores called conidia, sporangiospores, or zoospores.

• Fungi reproduce sexually through oospores, ascospores, and basidiospores.

• The sexual cycle involves three steps: 

Plasmogamy (fusion of protoplasm) →Karyogamy (Fusion of nuclei) →Meiosis in zygote, which leads to production of haploid spores

Four classes of kingdom fungi:

1. Phycomycetes
