AP BIOLOGY

Detailed explanation-1: -There are two main types of sclerenchyma cells: fibers and sclereids. Fibers are very elongated cells that can be found in stems, roots, and vascular bundles in leaves. Fibers impart fibrousness as in the case of asparagus.

Detailed explanation-2: -The areas in between the vascular bundles, also known as the interfascicular region, are mostly comprised of sclerenchyma fibers (Fig. 3B). These fibers, along with chlorenchyma, are also located in the layer of cells between the epidermis and outer vascular bundle, a region referred to as the cortex.

Detailed explanation-3: -The transport itself happens in the stem, which exists in two forms: xylem and phloem. Both these tissues are present in a vascular bundle, which in addition will include supporting and protective tissues. In addition, there is also a tissue between xylem and phloem which is the cambium.

Detailed explanation-4: -So, the correct option is ‘Monocot stem’.

Detailed explanation-5: -They often occur in bundles or strands and can be found almost anywhere in the plant body, including the stem, the roots, and the vascular bundles in leaves.
