Microbiology

- without a separating wall or membrane

- nitrogen-containing polysaccharide (a carbon) that is principal component of the exoskeletons of arthropods and bodies of fungi

- One of the long slender tubes that develop from germinated spores and form the structural parts of the body of fungus

- In many species of fungi, haphae are divided into sections by cross-walls called septa

- a large mass of haphae is called mycelium

- long chains of connected cells

- mass of hyphae that forms the vegetative part of fungus

- fuzzy masses of hyphae (mold)

- obtain nutrients from dead organic material

- majority of fungi are saprobes

- divided by or having a septum

- obtain nutrients from living cells without harming them

- close and usually obligatory association of 2 organisms of different species that live together with mutual benefit

- obtain nutrients from living cells with harmful consequences to cells

• - heterotroph: use preformed (living or dead) organic material nutritionally
• - all fungi are heterotroph

- saprobes: fungi that require their nutrients come from dead organic material

- break down organic material into forms that are reusable by other living things

- round cells that grow on the side of the mother cell until they are ready to divide as new cells

Yeast: have single, round cells

Molds: Grow in long chains

• Mushrooms: seen on dead or decaying organic material
• (Slender stem and a rounded head w/spores on top of it.)

- Septate - have cross-walls separating individual cells

- Aseptate - lack cross-walls

- spores allow widespread dissemination of the organisms (scatter or spread widely)

- polysaccharide chitin

- Ergosterol

(cholesterol is what humans and prokaryots have)
