PMNP 2 Exam 2024 Newest Graded Rated A+
Cytokinins - Correct Answer-Promote growth through cell division, delay senescence,
stimulate morphogenesis
Cytokinin effects - Correct Answer-Varied effects due to different receptors in cells,
interact with auxin
Abscisic Acid (ABA) - Correct Answer-Induces dormancy, inhibits shoot growth, promotes
root growth, affects seed development
ABA characteristics - Correct Answer-Stimulates stomata closure, seed protein synthesis,
and dormancy induction
ABA-insensitive mutants - Correct Answer-Mutants germinate despite high ABA
concentrations, related to protein phosphatases
Tonoplast targeting - Correct Answer-Remains unclear in plant cells
Arabidopsis thaliana - Correct Answer-Model organism with small genome, extensively
studied
Polyploid - Correct Answer-Having multiple sets of chromosomes
, Endosperm - Correct Answer-Nutrient source for plant embryo development
Cotyledons - Correct Answer-Seed leaves of a developing embryo
Monocotyledon - Correct Answer-Plants with one seed leaf (e.g., grass)
Dicotyledon - Correct Answer-Plants with two seed leaves (e.g., A. thaliana)
Mutagenize - Correct Answer-Induce mutations in seeds for genetic studies
F1 generation - Correct Answer-Offspring of self-fertilized mutated plants
Hermaphrodite - Correct Answer-Organism with both male and female reproductive organs
Map-based cloning - Correct Answer-Using traceable markers for gene cloning
Ground tissue - Correct Answer-Tissue for metabolism, photosynthesis, and storage in
plants
Stomata - Correct Answer-Plant organs regulating gas exchange for photosynthesis and
transpiration
