Assertion : Grafting is not usually possible in monocots.
Reasons : Sucessfule grafting requires that cambia of both stock and scion fuse to form new vascular tissues.

Give scientific reason.Grafting is not possible in monocots.

Grafting is not possible in monocot because of (A) scattered vascular bundles (B) lack of cambium (C) collateral open vascular bundles (D) radial vascular bundles

Assertion : Grafting is attempted in those plants which show secondary growth. Reason : Cambium during secondary growth show cell division in both stock and scion.

These question consist of two statements each, printed as Assertion and Reason. While answering these questions you are required to choose any one of the following responses If both Assertion and Reason are true and Reason is a correct explanation of Assertion If both Assertion and Reason is a not a correct explanation of Assertion If Assertion is true but Reason is false If both Assertion and Reason are false Assertion: Gene flow increases genetic variations Reason: The random introduction of new alleles into recipient population and their removal from the donor population affects allele frequency

These question consist of two statements each, printed as Assertion and Reason. While answering these questions you are required to choose any one of the following responses If both Assertion and Reason are true and Reason is a correct explanation of Assertion If both Assertion and Reason is a not a correct explanation of Assertion If Assertion is true but Reason is false If both Assertion and Reason are false Assertion:Allelopathy is a form of ammensalism that occurs in plants Reason: Association of rooting plants with fungal hypate, is an important example of ammensalism.

ASSERTION TYPE QUESTIONS : These questions consist of two statements each, printed as Assertion and Reason. While answering these questions, you are required to choose any one of the following four responses. A. If both Assertion and Reason are true and Reason is correct explanation of Assertion B. If both Assertion and Reason are true but Reasou is not correct explanation of Assertion. C. If Assertion is true but Reason is false. D. If both Assertion and Reason are false. Assertion: Grafting is attempted in those plants which show secondary growth. Reason: Cambium during secondary growth show cel division in both stock and scion.

Assertion: Secondary growth usually occurs in dicotyledonous stems. Reason: The vascular cambium present between xylem and phloem possesses the ability to form secondary xylem and secondary phloem respectively.
