Why is the region of elongation of the root relatively shorter than that of the stem?
This is because the root's primary function is to absorb water and nutrients, which can be achieved more efficiently with a shorter elongation zone. In contrast, the stem requires a longer elongation zone to support the plant's growth and facilitate its ability to reach sunlight for photosynthesis.
What is the primary growth of a stem?
Primary growth of a stem refers to the elongation and thickening of the stem through cell division and cell elongation in the apical meristems located at the tips of the stem and branches. This growth process is responsible for increasing the length of the stem and forming new leaves and branches.
Auxins are plant hormones which tend to decrease stem length?
Yes, auxins are plant hormones that are known to promote cell elongation and growth. They can indeed have a inhibitory effect on stem elongation by promoting the growth of lateral buds or inducing apical dominance. This can result in shorter, bushier plants.
How does auxin produce phototropism?
Auxin accumulates on the shaded side of the plant stem due to light exposure, causing cells on that side to elongate and bend towards the light source. This creates the bending of the stem towards the light, known as phototropism. The differential growth of cells in response to auxin distribution results in the plant's ability to bend and grow towards light.
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.

Where are auxins produce?
Auxins are substances that promote stem elongation and inhibit the growth of lateral buds. They are produced in the stem buds and root tips of plants.
Where the elongation of roots and stem take place?
Meristem

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.
Is groundnut a root or stem?
Groundnut is a type of legume and it is neither a root nor a stem. It is actually a type of seed, commonly known as a peanut, that grows underground on the roots of the plant.
What plant hormones might be used to enhance stem elongation and fruit growth?
Auxin is a plant hormone that can be used to enhance stem elongation, while gibberellins can stimulate fruit growth. These hormones can be applied through synthetic forms or through natural sources like foliar sprays to promote desired plant growth responses.

Is carrot a root or a stem?
Carrot is a root vegetable.
Is Capsicum a root or a stem?
Capsicum is a fruit that grows from the flower of the capsicum plant. It is not a root or a stem.
Is yam a root or a stem?
root
