What else can I help you with?
Both cytokinins and gibberellins promote plant growth. Compare the ways in which these hormones stimulate growth.?
Cytokinins promote cell division and growth mainly in lateral buds and roots, leading to bushier plants. Gibberellins, on the other hand, primarily promote stem elongation and leaf expansion by stimulating cell elongation. Both hormones work together to regulate various aspects of plant growth and development.
A plant that produces too little of the gibberellins might?
A plant that produces too little gibberellins may exhibit stunted growth, reduced stem elongation, and delayed flowering. Gibberellins are important plant hormones that regulate various developmental processes such as germination, stem growth, and flowering.
What plant hormone is responsible for most tropisms?
Gibberellins are growth hormones that control plant height and bud development.
Which plant hormone is responsible for breaking the dormancy cycle in plants?
Gibberellins are plant hormones that are responsible for breaking dormancy in seeds by promoting germination and growth. They stimulate seed germination and help in initiating growth processes in plants.
What hormone is lacking in dwarf varieties of plants?
Gibberellin hormone is usually lacking in dwarf varieties of plants. Gibberellins are a group of plant hormones that regulate plant growth and development, and a deficiency can result in reduced elongation and a dwarf phenotype in plants.
Gibberellins cause plant growth by stimulating?
Gibberllins cause plant growth by stimulating cell division. It causes growth in the stems and leaves.
Both cytokinins and gibberellins promote plant growth. Compare the ways in which these hormones stimulate growth.?
Cytokinins promote cell division and growth mainly in lateral buds and roots, leading to bushier plants. Gibberellins, on the other hand, primarily promote stem elongation and leaf expansion by stimulating cell elongation. Both hormones work together to regulate various aspects of plant growth and development.
What substances help plant growth?
Growth regulators help in plant growth. Examples are auxin, gibberellins, cytokinens etc.
What is the effect do gibberellins have on stem?
They cause stems to grow longer due to an extended internode distance.
A plant that produces too little of the gibberellins might?
A plant that produces too little gibberellins may exhibit stunted growth, reduced stem elongation, and delayed flowering. Gibberellins are important plant hormones that regulate various developmental processes such as germination, stem growth, and flowering.
What plant hormone is responsible for most tropisms?
Gibberellins are growth hormones that control plant height and bud development.
Where do gibberellins work in a plant?
= a plant hormone/ endogenous plant growth substance hormone. they promote cell elongation of internodal regions. ie) in a dwarf plant the gene controlling gibberillins is turned off but if it is sprayed with gibberillins they will grow to normal height
Which plant hormone is responsible for breaking the dormancy cycle in plants?
Gibberellins are plant hormones that are responsible for breaking dormancy in seeds by promoting germination and growth. They stimulate seed germination and help in initiating growth processes in plants.
What hormone is lacking in dwarf varieties of plants?
Gibberellin hormone is usually lacking in dwarf varieties of plants. Gibberellins are a group of plant hormones that regulate plant growth and development, and a deficiency can result in reduced elongation and a dwarf phenotype in plants.
Auxins and giberellins are?
Auxins and gibberellins are plant hormones involved in regulating growth and development processes. Auxins are responsible for cell elongation, root formation, and apical dominance, while gibberellins promote stem elongation, seed germination, and flowering.
Japanese scientists found that the extraordinary growth of a certain rice plant was caused by?
Japanese scientists found that the extraordinary growth of a certain rice plant was caused by gibberellins. In Japan there is a lot of rice grown.
Which of these plant hormones hastens the ripening of fruit and helps to cause the fall of leaves flowers and fruit a cytokinins b auxins c ethylene d gibberellins?
auxins are group of related chemical substances which activity greatly affect the physiological processses in plant and animal.auxins helps in stimulating plant growth and also hasten fruit ripening.
