What is general characteristic of fungi? Achlorophillous (haven’t chlorophyle) Heterotrof Life as paracyte, saprofit, and can symbiosis Eukaryotik Thalus uniseluler dan ada yg multicellular
Uniseluler khamir / yeast ex : Saccharomyces Multiseluler kapang / molds/ hifa ex : Lepiota
Mengambil makanan dengan cara arbsorbsi Sel sel tidak berflagel, kecuali filum
chytridiomycota Tersebar luas di alam, tanah, vegetasi dan air

What is general characteristic of fungi?
Mampu membentuk spora Sifat : aerobik, non motil Tumbuh optimal pada pH 5,0 / t’ 25 °C Terdiri dari 4 divisi, such as ;
chytridiomycota, zygomycota, ascomycota, dan basidiomycota Glomeromycota, deuteromycota.
Tubuh disusun oleh benang –Benang yang disebut hifa. Hifa – hifa bersatu membentuk miselium. Ada pula yang miseliumnya berkembang membentuk tubuh buah.

What is general characteristic of fungi?Important
decomposers & recyclers of nutrients in the environment
Most are multicellular, except unicellular yeast
Lack true roots, stems or leaves

Khamir / Yeast
Uniseluler
Sel berbentuk oval / bulat, ø 3 – 5 µm
Beberapa membentuk pseudohifa
rantai sel irreguler
Beberapa bersifat dimorfik
- pada suhu ruang : bentuk hifa
- pada suhu 37 °C : bentuk khamir

The Characteristics of Fungi
Cell walls are made of chitin (complex polysaccharide)
Body is called the Thallus
Grow as microscopic tubes or filaments called hyphae

The Characteristics of Fungi
Some are edible, while others are poisonous

The Characteristics of Fungi
Produce both sexual and asexual spores
Classified by their sexual reproductive structures
9
Spores come in various
shapes

Anggota Fungi mendapatkan nutrisi melalui 3 cara :
1. Saprofit.
Menguraikan sisa bagian makhluk hidup yang sudah mati.
2. Parasit.
Mengambil nutrisi dari makhluk yang masih hidup.
Hidup bersama makhluk hidup lainnya.
3. Simbiosis.
Jamur Parasit
Hifa
Cacing Nematoda Malang
Lichen, Simbiosis Jamur dengan Algae

Hyphae - network of thin thread-like structures that form the “body” of a fungus
• hyphae contain cytoplasm
• hyphae grow and branch until they cover and digest the food source (upon which the fungi is growing)
• Tubular shape• ONE continuous cell• Filled with cytoplasm & nuclei• Multinucleate• Hard cell wall of chitin also in insect
exoskeletons
hypha - singular
hyphae - plural

Hyphae
Stolons – horizontal hyphae that connect groups of hyphae to each other
Rhizoids – rootlike parts of hyphae that anchor the fungus

Hyphae
Cross-walls called SEPTA may form compartments
Septa have pores for movement of cytoplasm
Form network called mycelia that run through the thallus (body)

Modifications of hyphae
Fungi may be classified based on cell division (with or without cytokinesis)
Aseptate or coenocytic (without septa)
Septate (with septa)

The Fungi KingdomParts of fungi:
Mycelium - a mass of hyphaemycelia - plural
•The mycelium is usually hidden in the soil, in wood, or another food source
• A mycelium may fill a single ant, or cover many acres
