Verified
what are the general parts/components of a microscope? -
Wet mount vs oil immersion techniques - Wet Mount Technique - direct examination of
living specimens or non living materials to be examined for a short time
Oil Immersion Technique - allows the highest magnification to be used due to the
refractive index of the oil to be the same as the lenses
What does a scientific name consist of? - consists of both genus and species names.
(ex. Felis concolor)
what are the domains of life? - -Eukaryota
-Eubacteria
-Archaea
what are the shapes of bacteria? - -Spirillum volutans
-Coccus spp.
-Bacillus coagulans
How do bacteria reproduce? - -Binary fission
-Endospore reproduction
-Conjugation
what is a holotroph? - *Lack a cell wall and are usually motile
*Most are holotrophs (engulf food into vacuoles whole, where is it digested)
What are lichens? Types of lichens? - *Symbiotic relationship between an algae and a
fungus
Three different types-
-Crustose
-Fruticose
-Foliose
What does alternation of generations mean? - *Sporic Sexual Reproduction allows a
mixture of genes when reproducing
*generations- two alternating multicellular generations: a diploid (2n) sporophyte and a
haploid (1n) gametophyte
what are 3 characteristics of terrestrial plants? - -Eukaryotic
-Food stored as starch
-Cell walls made of cellulose
-Specialized tissues and organs
