Crocosmia corm with the tunic partly stripped to show its origin at the nodes on the corm cortex. Crocosmia corm anatomy, showing tunic, cortex of storage tissue, central medulla, and emergence of a new corm from a bud near the top. Crocosmia corm with stolons emerging through the tunic. The stolons originate at the axillary buds of the corm ...
Structure of RuCl(gly)(CO) 3, known as CORM-3. Carbon monoxide-releasing molecules (CORMs) are chemical compounds designed to release controlled amounts of carbon monoxide (CO). CORMs are being developed as potential therapeutic agents to locally deliver CO to cells and tissues, thus overcoming limitations of CO gas inhalation protocols.
Both sexual and asexual means are used to increase the number of plants; seeds and multiplication of corms are the most common means of production, but tissue culture can be used, [114] most commonly for saffron crocus. New corms are formed on top of the older corm which withers away, and cormels are produced from axillary buds. [112]
Internally a corm is mostly made of starch-containing parenchyma cells above a more-or-less circular basal node that grows roots. Corms are sometimes confused with true bulbs; they are often similar in appearance to bulbs externally, but corms are internally structured with solid tissues, which distinguishes them from bulbs, which are mostly ...
In biology, tissue is an assembly of similar cells and their extracellular matrix from the same embryonic origin that together carry out a specific function. [1] [2] Tissues occupy a biological organizational level between cells and a complete organ. Accordingly, organs are formed by the functional grouping together of multiple tissues. [3]
Corm - Short, upright, hard, or fleshy stems covered with thin, dry papery leaves. Rhizome - With reduced scale-like leaves. The top can generate leafy stems while the bottom can produce roots. Iris and many grasses. Stolon - Horizontal stems that run at or just below the soil surface with nodes that root and long internodes, the ends produce ...
The contractile function of vascular smooth muscle regulates the lumenal diameter of the small arteries-arterioles called resistance arteries, thereby contributing significantly to setting the level of blood pressure and blood flow to vascular beds. Smooth muscle contracts slowly and may maintain the contraction (tonically) for prolonged ...
The contractile vacuole has several structures attached to it in most cells, such as membrane folds, tubules, water tracts and small vesicles. These structures have been termed the spongiome; the contractile vacuole together with the spongiome is sometimes called the "contractile vacuole complex" (CVC). The spongiome serves several functions in ...
