A funiculus is a bundle of one or more nerve fascicles . Funiculi in the spinal cord are portions of white matter. Examples include: Anterior funiculus of the spinal cord. Lateral funiculus of the spinal cord.

The hilum is the position of attachment of seed with its stalk, the funiculus. Near the hilum a small opening is present, called micropyle, through which water enters the seed. Sometimes a ridge is present beyond the hilum, opposite the micropyle, it is called raphe. It represents the base of the funiculus which becomes fused with integument.

Some seeds also show chalaza (place of origin of seed coats) and raphe (part of funiculus fused with seed wall). The embryo consists of an axis or tigellum to which are attached one (in monocotyledonous seeds) or two (in dicotyledonous seeds) seed leaves or cotyledons.

The juicy edible part of the litchi fruit (aril) is an outgrowth of the funiculus that develops after fertilization. The cotton fibres are the elongated epidermal cells of the seed-coat. These fibres are single-celled and thin walled. They attain a length of upto 45 mm and have characteristic twists.

On the basis of position of micropyle, with respect to the funiculus, ovules are 6 types: 1. Orthotropous ovule: It is atropous or straight, where the micropyle, chalaza and the funiculus, all are in the same line. Ex- Cycas, Family Polygonaceae and Piperaceae. 2. Anatropous ovule: It is of the most common occurrence more than 80% of angiosperm ...

The ovule in a flower is an integumented mega-sporangium within which the meiosis and megaspore formation takes place, which develops into a seed after fertilisation. Each ovule usually consists of a nucleus invested by one or two integuments and a …

The ovary and style are composed of epidermis, ground tissue of parenchyma, and vascular bundles. The outer epidermis is cuticularized and may have stomata. The ovule consists of a nucellus which encircles the sporogenous tissue. There are two integuments of epidermal origin, and a stalk, funiculus.

The funiculus expands greatly in presence of moisture producing funicular cord and the base of the funicular cord is the hapteron (p1. haptera) (Fig. 296D & E) which is quite sticky and adheres easily to solid surface. Before expansion, the funicular cord …

ADVERTISEMENTS: In this article we will discuss about the root stem transition in plants. The change in arrangement of vascular tissues of roots having separate strands of phloem and xylem with exarch protoxylem to collaterally placed phloem and xylem with endarch protoxylem of stem is commonly referred to as root-stem transition. In higher plants root […]

(3) Amphitropous or transverse, where the main body of the ovule is placed more or less at right angles to the funiculus, e.g. Lemna (B. Kshudi-pana). (4) Campylotropous or curved, where the main body of the ovule is curved or bent becoming horse-shoe-shaped and is arranged more or less at right angles to the funiculus, e.g. mustard. Floral ...
