Learning Objectives Describe features, functions, and composition of plant organs, tissues, and cell types Relate morphology (roots, shoots, leaves, tissue systems, cell types) to function Differentiate monocot and eudicot body plan characteristics Recognize relationships between embryonic structures and mature plant morphology

Collenchyma may form cylinders or occur as discrete strands and is one of the three ground, or fundamental, tissues in plants, together with parenchyma (living thin-walled tissue) and sclerenchyma (dead support tissue with thick cell walls).

Q1: Distinguish between the following: collenchyma cell and. sclerenchyma cell; tracheid and vessel element; perforation plate. and pit; sieve cell and sieve-tube element; callose and P-protein. Collenchyma: fibrous under epidermous, support for young shoots, stretchy. alive. Sclerenchyma: dead thick lignated, bunched in seeds and fruit.

Leaves, fruits, and flowers are the regions where the parenchyma tissue is present. Parenchyma is found in soft plant parts, including leaf mesophyll, flowers, fruits and young stems. It is also present in petiole ground tissue, leaf mesophyll, and also in vascular bundles. Hope it helps you Stay safe

The parenchyma of the spleen is divided into two functionally and morphologically distinct compartments (red pulp and white pulp) divided by a tissue layer called the marginal zone. Outside the marginal zone is the perifollicular zone which contains sheathed capillaries and blood-filled spaces without endothelial lining.
