fungi cell wall called septa are made of ?
chitin! - which is the same substance from which exoskeleton of arthopods are made of.
septa are perforated to allow for exchange of cytoplasm between cells.(called cytoplasm streaming)
with the exception of yeasts, fungi are
multicellular
a fungal cell may contain more then one nuclei
a nuclei in one cell may or may not be identical.
fungi spend most of their lives in ?
haploid stage
fungi can reproduce?
sexually or asexually
sexual reproduction occurs when conditions are tough
asexual reproduction occurs when conditions are good , which makes sense as you would want offspring that are same as the parent when conditions are good.
in yeasts, asexual reproduction occurs by ?
budding. also called cell fission, smaller cell pitches off a parent cell.
