Structure of Hydra Hydra is a type of invertebrate with the following structures: Tentacles: Hydras have long and slender tentacles that protrude from their body. These tentacles play a crucial role in their survival as they are used to capture food.
Hydra Octopus of the Microscopic World Useful In Medical Research
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.
Hydra Reproduction and Regeneration Zoology
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.

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.
Structure Of Hydra Parts And Functions
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 proxiยญmal end, the point of attachment is the pedal disc. 3.

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.

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.

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.

Hydras have two significant structures on their body: the "head" and the "foot". When a Hydra is cut in half, each half regenerates and forms into a small Hydra; the "head" regenerates a "foot" and the "foot" regenerates a "head". If the Hydra is sliced into many segments then the middle slices form both a "head" and a "foot". [6]
