What s the significance of this naing Imai-plant gro other words, why dont plants have endocrine like organs? 2. Some mutant corn plants start seed germination while the kernels are still on the cob, a condition known as 'vivipary'. Researchers found that the mutants can't regulate abscisic acid (ABA) and can be of two types: one that can overcome this condition by exogenous application of ABA and another type that cannot. Explain why ABA absence would promote vivipary and how the two types could be explained in terms of gene expression? 3. In 2010, NASA sent Arabidopsis seeds to the International Space station and grew them under zero gravity conditions. To their surprise, the plants germinated and developed shoot androot systems growing in opposite directions and the root showed patterns of normal root growth behavior. What might this suggest about gravity's role in plant seed germination and development and how do

Please answer question 2
What's the significance of this finding in terms of animal-plant growth and response differences? In other words, why don't plants have endocrine like organs? 2. Some mutant corn plants start seed germination while the kernels are still on the cob, a condition known as 'vivipary'. Researchers found that the mutants can't regulate abscisic acid (ABA) and can be of two types: one that can overcome this condition by exogenous application of ABA and another type that cannot. Explain why ABA absence would promote vivipary and how the two types could be explained in terms of gene expression? 3. In 2010, NASA sent Arabidopsis seeds to the International Space station and grew them under zero gravity conditions. To their surprise, the plants germinated and developed shoot andrroot systems growing in opposite directions and the root showed patterns of normal root growth behavior. What might this suggest about gravity's role in plant seed germination and development and how do you think plants were able to diversify shoot and root systems without gravity?
