1 Schematic representation of the Hydra body plan. Hydra is a hollow
Does Hydra have tissues and organs? Hydra has reached the tissue grade of organization, but it lacks organs. It consists of a tube about 5 mm long formed by two epithelial layers (endoderm and ectoderm). It has a head consisting of a mouth surrounded by a ring of tentacles at one end and an adherent disk, the foot, at the other end.

1. It is a fresh water form cosmopolitan in distribution. ADVERTISEMENTS: 2. It is found attached to aquatic weeds. 3. Body differentiated into a long tubular trunk and a hypostome or mouth surrounded by a ring of long tentacles. 4. Through the body runs a cavity- the coelenteron which also extends into tentacles. 5.

Structure In general, the body of a hydra is organized like a tube (polpy-like) with tentacles arranged around the head pole of the organism. A closer look, however, reveals a mouth opening (at the top pole of the organism surrounded by tentacles), a peduncle as well as a basal disk through which the organism attaches to the substrate.

Photomicrography of Hydra The Canadian Nature Photographer
The body wall of Hydra is organized as an epithelial bilayer (ectoderm and endoderm) with an intervening extracellular matrix (ECM), termed mesoglea by early biologists. Morphological studies have determined that Hydra ECM is composed of two basal lamina layers positioned at the base of each epithelial layer with an intervening interstitial matrix.

Structure of Hydra: Hydra belongs to the class Hydrozoa, Phylum cnidaria. 1. The body is more or less cylindrical (Fig. 20.1) and one end remains attached to a submerged object, wood or stone. 2. The attached end is known as the proximal end, the point of attachment is the pedal disc. 3.

The hydra resembles a slender sea anemone. At the top of the organism is a number of tentacles arranged in a circle around the hydra's mouth. These tentacles are controlled by a simple neural net. Tiny stinging cells, called nematocysts, cover the tentacles. While harmless to humans, these cells can incapacitate the tiny organisms the hydra eats.

The body wall is comprised of two layers of cells separated by a thin, structureless layer of connective tissue called the mesoglea and the enteron, a cavity containing intestinal organs. The lower end of the body is closed, and an opening at the upper end both ingests food and ejects residue.

Sections of hydra studied with the electron microscope show various structures which have been identified by referring to control histological sections and to previous descriptions. Certain features have also been examined in frozen-dried sections under the light microscope.In the ectoderm, epithelio-muscular cells contain various organelles, and also smooth longitudinal muscle-fibres with.

Structure of Hydra: Hydra has a slender tubular body and exhibits distinct radial symmetry (Fig. 12.2). The body is extremely contractile and the length varies from 10 to 30 mm. The lower end of the tubular body is closed and this side is designated as the aboral or proximal end. This end of the body is named as the foot or basal disc which is.

Hydra Regeneration is a fascinating phenomenon that allows these animals to regenerate their entire body within a few days. This article reviews the cellular and molecular mechanisms that underlie this process, and how they relate to the evolution of stem cells and tissue regeneration in other organisms.
