Questions Related to plant hormones
Interfascicular cambium formation is induced by
-
Auxin
-
Cytokinin
-
Gibberellin
-
Ethylene
Cytokinin is a plant hormone which is involved in growth and development of plants. It is required for the cambial growth. Kinetin, a type of cytokinin promotes cell division. It induces formation of interfascicular cambium in plants.
Cytokinin synthesis is maximum in
-
Roots
-
Leaves
-
Shoot tip
-
Fruit
Cytokinin is a plant hormone. It promotes cell division. It also delays the destruction of chlorophyll and protein. It shows delay of senescence in leaves. It is mostly produced in the root apex. Roots synthesize maximum amount of cytokinin hormone.
Which of the following is a cytokinin?
-
Phytochrome
-
Leucine
-
Ethylene
-
Zeatin
Cytokinin is a plant hormone which is involved in various physiological processes of plants. Zeatin is the most common type of naturally occurring cytokinin. It is found in maize. It is also found in the coconut milk. It promotes cell division.
Induction of cell division and delay in senescence are due to
-
Gibberellin
-
Auxin
-
Cytokinin
-
Ethylene
Cytokinin is a plant hormone. It plays major role in cell proliferation and cell division. It also delays the destruction of chlorophyll and protein. During senescence, cytokinin levels are low. It delays in senescence of leaves when sprayed externally by delaying the destruction of chlorophyll and proteins in leaves
Which is not a function of cytokinin?
-
Delay is senescence
-
Breaking seed dormancy
-
Promoting bud dormancy
-
Promoting stomatal opening
Cytokinin (CK) is a plant hormone. It promotes cell division and delays senescence in plants. It improves nutrient mobilization and thus delays leaf senescence. When applied externally, it mobilizes nutrients towards sites of application. It also promotes stomatal opening along with auxin hormone. It also breaks the dormancy of seeds and induce seed germination.
Which plant hormone was discovered as kinetin?
-
ABA
-
Ethylene
-
Auxin
-
Cytokinin
Kinetin was first isolated from herring sperm DNA by Miller and Skoog. It is a type of naturally occurring cytokinin, a plant hormone. It promotes growth. It induces cell division or cytokinesis.
Transport of cytokinin in the plant body is
-
Basipetal
-
Lateral
-
Acropetal
-
On all sides
Cytokinin is a plant hormone that is synthesized in the root. It shows acropetal transport. It is exactly opposite to the basipetal transport of auxin hormone. Acropetal transport is the translocation of hormone towards the shoot apex.
Natural cytokinins are synthesised in tissues that are
-
Storing food
-
Differentiating
-
Dividing
-
Senescent
Cytokinin is a plant hormone that is involved in various physiological processes. It is growth promoting hormone. It stimulates cell division or cytokinesis and hence the name was given. It is synthesized in high concentration in tissues that are dividing such as cambium.
Natural cytokinins are synthesized in tissues for
-
Differentiating
-
Senescent
-
Dividing
-
Storing food
The precursor of Serine and Cytokine is?
-
Oxalocetate
-
$3$-phosphoglycerate
-
Phosphoenolpyruvate
-
Erythrose-$4$-phosphate
