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.
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).
Yes. Embryonic stem cells are controversial due to the destruction needed of a fetus. The debate over this is whether the unborn child has a right to life. (Embyonic stem cell debate). However, there are adult stem cells that come from adults. Scientists have been able to get these adult stem to replicate embryonic stem cell properties, and depending on who you ask, the adult stem cells have proven more useful than embryonic stem cells. Since adult stem cells do not destroy anybody, there is nearly non-existant debate with this.
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.
Rhizomes are underground stems that grow horizontally and produce new shoots, while stem tubers are swollen underground storage structures that store nutrients for the plant. Rhizomes can give rise to new plants, while stem tubers are primarily used for storing energy.
Compound leaves are divided into multiple leaflets along a central stalk, while simple leaves consist of a single leaf blade attached to the stem.
Vascular bundle arrangement
Monocotyledons have seeds with only one cotyledon and their vascular bundles are scattered in the stem. Examples of monocotyledon plants include grasses, lilies, and orchids. Dicotyledons have seeds with two cotyledons and their vascular bundles are arranged in a ring in the stem. Examples of dicotyledon plants include roses, sunflowers, and oak trees.
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
the plant which have only one spherical like organ(from where root&stem arises) is called monocotyledon 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
one has a strong stem and another doesn't
guava tree has hard stem while banana plant has soft stem
Leaf tendrils originate either from stipules or leaflets whereas the stem tendrils are modification of axillary buds representing the stem branches.
A cordyline will develop a stem whereas phormiums don't.
