Reproduction in Fungi- Part-3: Sexual Reproduction (Lecture Notes & PPT)


methods of sexual reproduction in fungi

Sexual Reproduction in Fungi

Ø  Fungi reproduce by vegetative, asexual and sexual methods

Ø  This post describes the Sexual Reproduction methods in fungi

Ø  Sexual reproduction takes place in all groups of fungi except Deuteromycetes

Ø  Fungi may be monoecious (bisexual) or dioecious (unisexual)

Ø  Moneoecious species produce two sex organs (male and female) in the same thallus, thus they are called homothallic

Ø  Dioecious forms produces sex organs in separate thalli, hence called heterothallic

Ø  Based on the complexity of sexual reproduction, fungi can be grouped into two categories:

(1). Eukarpic fungi

(2). Holocarpic fungi

Reproduction in Fungi- Part-2: Asexual Reproduction (Lecture Notes & PPT)


Spores in fungi

Asexual Reproduction in Fungi

Ø  Fungi reproduce by vegetative, asexual and sexual methods

Ø  This post describes different types of ASEXUAL REPRODUCTION methods in fungi

Ø  About 20% fungi propagate only by asexual means

Ø  Asexual reproduction take places during favorable condition by the formation of a variety of spores

Ø  Such spores produced by asexual reproduction are called mitospores

Ø  Spores may be unicellular (Aspergillus, Penicillium) or Multicellular (Alternaria, Cercospora)

Ø  Based on the number of cells in spores, asexual spores of fungi are classified into:

1. Amerospore: one celled spores

2. Didymospore: two celled spores

Reproduction in Fungi- Part-1: Vegetative Reproduction (Lecture Notes & PPT)


how fungi reproduce vegetatively

Vegetative Reproduction in Fungi

Ø  Fungi reproduce by vegetative, asexual and sexual methods

Ø  This post describes different types of Vegetative reproduction methods in fungi

Ø  Vegetative reproduction helps to increase the number of individuals in the population

Ø  Vegetative reproduction in fungi occurs by:

(1). Fragmentation

(2). Fission

(3). Bud fission

(4). Budding

(5). Gemmae

(6). Sclerotia

(7). Rhizomorphs

(8). Mycelial cords

CSIR JRF NET Exam Minimum Cut-off Percentage of Last Five Years (A Comparison)


net june 2016 cut off marks

Joint CSIR UGC JRF NET Examination

Category wise minimum cut-off percentage of Joint CSIR UGC JRF NET Examination in different disciplines (Life Science, Chemical Science, Earth Science, Mathematical Science, Physical Science and Engineering Science) for the selection of Junior Research Fellowship (JRF) and Eligibility for Lectureship (NET) of June and December batches (December 2011 onwards). The comparison of cutoff marks may help you to build confidence to face the examination. As you can see there is no fixed cut-off percentage for the JRF Fellowship and Lectureship examination. The minimum cutoff percentage varies every time, every year. CSIR have mentioned that there are no separate cutoff marks for section A, B and C part of the paper. The cumulative percentage of all parts is taken into consideration for the preparation of final rank list.

Nutrition in Fungi Key Points with PPT (Saprophytic, Parasitic, Symbiotic and Predator Fungi)


nutrition in fungi

Ø  Fungi are heterotrophic in nutrition

Ø  They are chlorophyll deficient plants and hence they cannot manufacture carbohydrates using carbon dioxide, water and sunlight

Ø  Fungi are with simple structural organization, thus they always depends on dead or living organic matter for their energy requirements

Ø  On the basis of mode of nutrition, fungi are classified into four groups:

(1). Saprophytes

(2). Parasites

(3). Symbionts

(4). Predacious fungi
