What is the role of gibberellin in rosette plants?
Bolting, characterized by the elongation of internodes before flowering in rosette plants such as beet and cabbage, is a result of the influence of gibberellins.
Very Short Answer
Name the bacteria responsible for conversion of nitrite to nitrate.
Nitrobacter bacteria responsible for conversion of nitrite to nitrate.
What is denitrification?
Denitrification is the microbial breakdown of nitrate compounds into nitrite and Nitrogen gas. This process is facilitated by denitrifying bacteria such as Thiobacillus, Pseudomonas, Spirillum, found in the soil. These microbes play a crucial role in the natural nitrogen cycle by converting nitrates into gaseous forms, promoting nutrient recycling.
Which is the plant stress hormone?
Abscisic acid functions as the stress hormone within plants.
What does it mean by ‘open growth’?

What is symplast pathway?
The symplast pathway across the root occurs when water, absorbed by root hair, moves through living cells via plasmodesmatal connections between them.
Why do diurnal changes occur in osmotic potential of gaurd cells?
1. During the daytime, the enzymatic activity of phosphorylase facilitates the conversion of starch into sugar, contributing to increased sugar levels. 2. Conversely, during the nighttime, there is a reversal in this process, with sugar being converted back into starch through the action of phosphorylase. 3. These diurnal variations in enzymatic activity result in dynamic … Read more
Mention the shape of gaurd cells in cyperus.
Guard cells exhibit both kidney-shaped and dumbbell-shaped forms.
