KU BIOL 152 Exam 2 UPDATED Exam
Questions and CORRECT Answers
cellular division in eukaryotes - CORRECT ANSWER - linear dna and nucleus
diploid organism 2n=4 chromosomes
animal and plant cycles - CORRECT ANSWER - 1) diploid (2n)
2) meiosis
3) haploid (n)
3.5) fusion of sperm and eg
4) fertilization
4.5) zygote
cellular divison in eukaryotes: mitosis - CORRECT ANSWER - identical copy is made of
each chromosome (homologous pair)
chromosome line up in the center
duplicate set of chromosomes separate
cell membrane divides
cellular divison in eukaryotes: meiosis - CORRECT ANSWER - identical copy is made of
each chromosome (homologous pair)
homologous pairs undergo crossing (genetic recombination)
cell divides twice resulting in 4 haploid cells
animal life cycles - CORRECT ANSWER - 1) mouse (2n)
1.5) mitosis - ovary and testee
2) meiosis
3) gamete (n)
,4) fertilization
4.5) zygotes and mitosis
alternation of generations: plants - CORRECT ANSWER - 1) sporophyte (2n) - produce
spores
1.5) mitosis - sporangium
2) meiosis
2.5) mitosis - spores
3) gametophyte (n) - produce gamettes
4) fertilization
4.5) zygotes and mitosis
fungi life cycle (sexual) - CORRECT ANSWER - 1) mycellum
1.5) plasmogamy
2) heterokaryotic
3) karyogamy
3.5) zygote
4) meiosis
4,5) dispersal and germination
fungi life cycle (asexual) - CORRECT ANSWER - 1) spores
1.5) dispersal and germination
2) mycelium
how do you increase variation? - CORRECT ANSWER - sexual reproduction recombines
alleles and combines two sets of chromosomes
this leads to an increasement of heterozygosity and variation within a set of offspring
, prokaryotes - CORRECT ANSWER - asexual (binary fission)
horizontal gene transfer (increase genetic diversity)
eukaryotes - CORRECT ANSWER - asexually (miotic cellular divison), sexually
(meiosis), or both
self fertilization - single individual produces male and female gametes
only eukaryotes have sexual reproduction T/F - CORRECT ANSWER - true
no animal can reproduce asexually T/F - CORRECT ANSWER - false
asexual reproduction allows greater ability to adapt than sexual reproduction T/F - CORRECT
ANSWER - false
meiosis directly results in gamete cells in all eukaryotes T/F - CORRECT ANSWER -
false
in fungi, meiosis happens quickly after formation of diploid nuclei T/F - CORRECT
ANSWER - true
karyogamy produces heterokaryotic hyphae T/F - CORRECT ANSWER - false
a sporangium is a structure on a sporophyte in which meiosis occurs T/F - CORRECT
ANSWER - true
spores grow into sporophytes T/F - CORRECT ANSWER - false
