1. at monocot stem.
-stem hairs are absent.
-sclerenchyma hypodermis.
-internal tissue is not differentiated into different concentric layer but there is a common mass called ground tissue.
-vascular bundles is found scattered in ground tissue.
-presence of water cavity.
2. at dicot stem
-stem hairs are present.
-collenchyma hypodermis.
-internal tissue is differentiated into hypodermis, cortex, endodermis, pericycle, medullary ray and pith.
-vascular bundle is found between preicycle and pith.
-water cavity is absent.
no phloem in dicotyledons
it's dicotyledon.--> No! Pine is a gymnosperm ("naked seed"; no ovary), and thus the terms dicotyledon (dicot or eudicot) and monocotyledon (monocot) do not apply to conifers like Pine. The terms "monocotyledon" and "dicotyledon" (or more accurately "eudicot") only apply to the angiosperms (flowering plants containing ovaries/"vessels"). Pine is NOT an angiosperm, thus this these terms DO NOT apply to Pine (or any other conifers).
Roots and stem get modified for storage or performing any specific function such as climbing or overcoming hostile environmental conditions. The basic difference between a root and stem is that in case of root, the primary vascular bundles are radial whereas in stems these are conjoint and collateral.
rhizomes are underground horizontal stems tubers are enlarged underground stems
It means they do have viens:)<3
An embryonic stem cell potentially can develop into ANY cell in the body theoretically without limit to replenish, and an adult stem cell is only able to mature into a specialised tissue cell from which tissue the cell is positioned.
explain the differences between elodea stem and dicot stem
yes, because it veins are not parallel and the stem are wood
Parts of a stem are tubes and covering
the difference between scion and stock is that scion is the cut stem of a plant while stock is the stem attached to the ground
it's dicotyledon.--> No! Pine is a gymnosperm ("naked seed"; no ovary), and thus the terms dicotyledon (dicot or eudicot) and monocotyledon (monocot) do not apply to conifers like Pine.

the plant which have only one spherical like organ(from where root&stem arises) is called monocotyledon plant
The shoot is the new plant, the baby. The stem is the woody part of a grown plant.
Stems are thicker than trims
A woody stem is usually much bigger and has a woody coating, like a tree. A herbaceous stem is softer and more flexible, like a flower stem.
A graph and stem is different to a leaf plot because in a leaf plot, there is a stem and leaf in a plot, while in a graph and stem, there is a leaf and stem in a graph.
A tree has a massive trunk (stem), whereas a herbaceous plant has a very small stem
Roots and stem get modified for storage or performing any specific function such as climbing or overcoming hostile environmental conditions. The basic difference between a root and stem is that in case of root, the primary vascular bundles are radial whereas in stems these are conjoint and collateral.
