Frequently asked questions
What is the Golgi body (Golgi apparatus) and its role in plant cells?
The Golgi body (Golgi apparatus) is a cell organelle involved in modifying, packaging, and sorting proteins and lipids for secretion or delivery to other organelles.
What are the merits and demerits of mass selection in plant breeding?
Mass selection offers simplicity and speed but may result in low genetic gain and reduced uniformity; its effectiveness depends on heritability and selection intensity.
How do scientifically produced seed and grain differ, and what determines seed quality?
Scientifically produced seed refers to seeds produced under standardized breeding and production practices, whereas grain is the harvested product; seed quality is determined by viability, uniformity, and vigor.
What is diffusion pressure and why is it significant in plants?
Diffusion pressure is the force driving the movement of substances (e.g., water) due to concentration differences; it influences rates of diffusion and transport in plant tissues.
What are appropriate approaches for breeding crop varieties for wide adaptability?
Approaches include evaluating genotypes across diverse environments, incorporating broad-sense and specific adaptability, and using multi-environment trials and appropriate selection criteria.
What is somatic vs meiotic crossing-over and its mechanism?
Somatic crossing-over refers to genetic exchange in somatic cells (rare) while meiotic crossing-over occurs between homologous chromosomes during meiosis, increasing genetic variation through recombination.
