SOLUTIONS 2024

asexual reproduction - -directing cells to divide and develop into new tissues and

organs without a partner


sexual reproduction - --takes more time and energy than asexual reproduction


-genetically diverse offspring


-requires fertilization


-requires haploid gametes


-mating


most plants and animals produce_______ - -gametes called eggs and sperm


Meiosis - -nuclear division that forms haploid cells


Meiosis I - -diploid cells divide to create 2 haploid cells, each with one of the

homologous chromosomes


Meiosis II - -2 haploid cells divide to form 4 haploid cells, which develop into eggs or

sperm


Prophase I (Meiosis) - --chromosomes condense


-nuclear envelope breaks down

, -spindle fibers start to form (microtubules)


-crossing over occurs


Metaphase 1 (Meiosis) - -Pairs of homologous chromosomes move to metaphase

plate


Anaphase I (Meiosis) - -homologous chromosomes separate and move to opposite

poles of the cell


Telophase and Cytokensis (Meiosis) - --chromosomes gather at poles of the cell


-cytoplasm divides


Prophase II (Meiosis) - --2 cells


-a new spindle forms around the chromosomes


Metaphase II (Meiosis) - -chromosomes line up at the metaphase plate/equator


Anaphase II (Meiosis) - --2 cells


-centromeres divide


-chromatids move to opposite poles of the cells


Telophase II and Cytokinesis (Meiosis) - --goes from 2 cells to 4 cells


-nuclear envelope forms around each set of chromosomes


-cytoplasm divides
