animals
How do fungi digest?
- Externally
- Stomach on outside
- push out digestive enzymes into the environment to break down complex molecules
What are hyphae?
- threadlike filaments that make up fungal bodies
- fragile, but can grow through tough substrates
- grow from the tip
What parts of the fungi are made up of hyphae
-mycelium and fruiting body
How do septa form
- inward growth from the wall
- allows some things to move through and others not by plugging passage
Parenthosomes
- shaped like parenthesis
- found on either side of dolipore septa
- function isnt fully known
What are dolipore septa
-specialized septa shaped like donuts on a stick
Coenocytic
-lacking septa (aseptate)
Spitzenkorper
- a collection of vesicles at the tip of a hyphae
- tiny black dots that form a bigger black dot
What are important components of fungal digestion?
- free water for metabolizing
- oxygen
- acidity, most perfer pH 4-7 and can change pH where theyre feeding
- light, can speed up growth and spark reproduction
What are the different reproductive strategies of fungi and their advantages
- SEXUAL - genetic recombination, adaptation
- ASEXUAL - prevents dilution, can produce more
- PARASEXUAL - genetic recombination, transferring genes without sex
- both sexual and asexual - most species
What does carp refer to
-reproductive structure
