This tissue system is present between the dermal tissue and forms the main bulk of the plant body. Parenchyma cells have thin primary walls and usually remain alive after they become mature. Parenchyma forms the "filler" tissue in the soft parts of plants, and is usually present in cortex , pericycle , pith , and medullary rays in primary stem ...
Vascular bundles are present throughout the monocot stem, although concentrated towards the outside. This differs from the dicot stem that has a ring of vascular bundles and often none in the center. The shoot apex in monocot stems is more elongated. Leaf sheathes grow up around it, protecting it. This is true to some extent of almost all monocots.
In angiosperms, intercalary (sometimes called basal) meristems occur in monocot (in particular, grass) stems at the base of nodes and leaf blades. Horsetails and Welwitschia also exhibit intercalary growth. Intercalary meristems are capable of cell division, and they allow for rapid growth and regrowth of many monocots.
Syngonium plant with fruits creeping over the tree at Chiapas, Mexico Syngonium podophyllum is a popular houseplant. It is an elongated, climbing or creeping herbaceous evergreen plant that reaches a height of 10–20 m (33–66 ft) with a sympodial growth type, lacking branches (branches off only after damage to the apical meristem ...
Bast fiber from oak trees forms the oldest preserved woven fabrics in the world. It was unearthed at the archeological site at Çatalhöyük in Turkey and dates to 8000-9000 years ago. [5] Dress of unspecified bast fibre, Yuracaré, Rio Chimoré, Bolivia 1908–1909. Cycling suit of linen bast fiber, New York, New York, United States, 1908
This is because the ancestral or primitive characters are inferred by means of the reconstruction of character states, with the help of the phylogenetic tree. So primitive characters of monocots may be present in some derived groups. On the other hand, the basal taxa may exhibit many morphological autapomorphies. So although Acoraceae is the ...
The epidermis is the outermost cell layer of the primary plant body. In some older works the cells of the leaf epidermis have been regarded as specialized parenchyma cells, [1] but the established modern preference has long been to classify the epidermis as dermal tissue, [2] whereas parenchyma is classified as ground tissue.

The flowers that present perianth—the most frequent case—are called perianthed, chlamydeous or "clothed". [ 8 ] In the perianth flowers may be the case that only present calyx, so they are called monoclamyds or, more usually, apetalous and the most conspicuous example is the urticaceae family.
