DON'T BE SHY

SAY HI!

HELLO! I am Fungi...

Nice to meet you~

What is fungi?

Fungi ;

Organisms in the Kingdom Fungi, the true fungi that also called the “Eumycota".

Fungus ;

The heterogenous group of organisms that have been studied traditionally by mycologists.

HYPHAE AND HYPHAL EXTENSION.

Fungal hyphae as they grow and branch, produce a network of filaments which constitutes the fungal mycelium. The mycelium expands by the extension of individual hyphae exhibit polar growth, that is they grow at their tips. Expansion of the mycelium is limitless if hyphae can continue to extend on the surface from which they can their nutrients. Nevertheless , changes take place as the mycelium ages and as that part of the substrate on which it is growing is no longer able to provide nutrients.

There are four different ages or developmental stages :

The apical growth zone

Extending the hyphal tip and adjacent part.
Provide the material and organelles requires for hyphal elongation.

The absorption zone

This zone partially overlaps with the apical growth zone.
Uptake of nutrients.

The storage zone

Proportion of the absorbed nutrients are stored as reserve substances.

The senescence zone

Oldest part of the mycelium.
Characterized by the presence of dark pigments and lysis may eventually take place.

What you need to know about fungi?

• For fellow vegetables and meat lovers. Sorry. Fungi are neither a plants, nor animals.

• Heterotrophic by absorption. They have no digestive system and no chlorophylls.

• Reproduced by spores. Can either be sexual and asexual.

• The primary carbohydrate storage product of fungi is glycogen.

Hyphea - microscopic thread that composed the body part of fungi.

Thallus - elongated hyphae as tip growth.

Mycellum - mass of hyphae.

Fruit body - structure that spore-producing cell.

Remember this...

If you ever cross on one :

How fungi obtains nutrients ;

Fungi are heterotroph.

Heterotroph - Obtains nutrients by digesting organic materials.

Even if fungi look like plants, they do not perform photosynthesis.

Fungi acquire their nutrients by absorption. The organic molecules are absorbed and digests from food outside its body by secreting hydrolytic enzymes. The enzymes decompose complex molecules to the simpler compounds that the fungus can absorb and use.
