Yeasts are without mycelium ascomycetes. In this asci are not organized in ascocarps. They reproduce asexually by budding, fission and combination of both. They are classified according to these criteria. They are also classified as true and false yeasts. True yeasts are those in which ...
Ascomycetes are also known as sac fungi. It includes pigment containing moulds, yeasts, morels etc. They are saprobic and act as a decomposer. Hyphae are septate except in yeast where they are unicellular. The septa give rise to central pores known as septal pores. They ...
Asexual reproduction occurs by sporangiospores, chlamydospores and oidia. These all are mitospores. Sporangiospores are developed under favorable conditions. Around 2 to 5 sporangiophores develop from holdfast. The tip of spoarangiophore forms sporangium. It is separated from rest of structures by columella. Sporangiums give rise to ...
Rhizopus occurs on stale bread in warm and moist season. It is saprobic and has affinity for carbohydrate rich organic food. The mycelium has different types of hyphae which are as follows: rhizoidal hyphae, stoloniferous, sporangiophores and zygophores. They all develop from holdfasts. Rhizoidal hyphae ...
These are lower group of fungi. They are without septate and have coenocytic hyphae. A both sexual and asexual form of reproduction occurs. Asexual reproduction occurs by zoospores and aplanospores. Sexual reproduction occurs by isogamous or heterogamous. This group is sub divided into oomycetes and ...
They are classified on the basis of number of factors. Few of these are 1. Morphology of fungus 2. Types of spores 3. Life cycle 4. Physiology 5. Biochemistry
The different variety of spores present in kingdom fungi are zoospores, sporangiospores, chlamydospores, oidia, conidia, ascospores, basidiospores and bi nucleate spores. Zoospores occur in phycomycetes and are mobile. The spores are naked and have flagella for locomotion. Sporangiospores do not have any flagella. They are ...
Vegetative reproduction involves fragmentation, fission, budding and sclerotia. In fragmentation mycelia break into different parts by injury or decay. Budding involves yeast. The main cell produces a protrusion which grows into a bud and forms a new individual. In fission, single cell divides into two ...
