Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R:
Assertion A: A flower is defined as modified shoot wherein the shoot apical meristem changes to floral meristem.
Reason R: Internode of the shoot gets condensed to produce different floral appendages laterally at successive node instead of leaves.
In the light of the above statements, choose the correct answer from the options given below:
Assertion A: A flower is defined as modified shoot wherein the shoot apical meristem changes to floral meristem.
Reason R: Internode of the shoot gets condensed to produce different floral appendages laterally at successive node instead of leaves.
In the light of the above statements, choose the correct answer from the options given below:
Both A and R are true but R is NOT the correct explanation of A
A is true but R is false
A is false but R is true
Both A and R are true and R correct explanation of A
The Correct Option is D
Solution and Explanation
Assertion A is true. A flower is indeed defined as a modified shoot in which the shoot apical meristem changes to floral meristem, leading to the formation of reproductive structures.
Reason R is also true. In a flower, the internode of the shoot is condensed, and this condensed region gives rise to different floral appendages (such as sepals, petals, stamens, and carpels) laterally at successive nodes instead of producing leaves. This phenomenon is a key characteristic of floral development.
Therefore, The correct option is (D): Both A and R are true and R correct explanation of A

The Tissue System
Epidermal Tissue System:
The epidermal tissue system forms the outer-most covering of the whole plant body and comprises epidermal cells, stomata, and the epidermal appendages – the trichomes and hairs. The epidermis is the outermost layer of the primary plant body. It is made up of elongated, compactly arranged cells, which form a continuous layer. The epidermis is usually single-layered.
Ground Tissue System:
All tissues except the epidermis and vascular bundles constitute the ground tissue. It consists of simple tissues such as parenchyma, collenchyma, and sclerenchyma. Parenchymatous cells are usually present in the cortex, pericycle, pith, and medullary rays, in the primary stems and roots. In leaves, the ground tissue consists of thin-walled chloroplast-containing cells and is called mesophyll.
Vascular Tissue System:
The vascular system consists of complex tissues, the phloem, and the xylem. The xylem and phloem together constitute vascular bundles. In dicotyledonous stems, cambium is present between phloem and xylem. Such vascular bundles because of the presence of cambium possess the ability to form secondary xylem and phloem tissues and hence are called open vascular bundles. In the monocotyledons, the vascular bundles have no cambium present in them. Hence, since they do not form secondary tissues they are referred to as closed.
