How many embryonic and adult tissue layers and found in jellyfishhydrasand sea anemones?
Jellyfish, hydras, and sea anemones are all part of the phylum Cnidaria and possess two embryonic tissue layers: the ectoderm and endoderm. These organisms are classified as diploblastic, meaning they have only these two primary germ layers. In contrast to triploblastic organisms, they do not have a mesoderm layer. As adults, they maintain these two tissue layers throughout their life cycle.
What does the presence of only two tissue layers make cnidarians?
The presence of only two tissues layers makes cnidarians diploblastic. These tissues layers consist of an epidermis (outer layer) and a gastrodermis (inner gut layer). Mesoglea, a type of jelly-like substance is between these layers.
Which specialized tissue type would you find muscle layers of the small and large intestines?
The muscle layers of the small and large intestines are composed of smooth muscle tissue, which is specialized for involuntary contractions. This smooth muscle is organized into two layers: an inner circular layer and an outer longitudinal layer, facilitating peristalsis and segmentation movements that aid in digestion and absorption.
What are the layers of Pluto?
pu & toe are the only two layers of Pluto get it!!!!
Skin is what type of connective tissue?
The skin is actually formed from two kinds of tissue. The epidermis is constructed from stratified squamous epithelium and the dermis is made up of dense connective tissue.
Which phyla have only two germ layers?
Phyla that have only two germ layers are Cnidaria and Ctenophora. These phyla are considered diploblastic, meaning they develop from two embryonic germ layers: endoderm and ectoderm. organs. This is in contrast to triploblastic animals, which have three germ layers (endoderm, mesoderm, and ectoderm).
Which phyla are diploblastic?
Cnidaria and Ctenophora are the two phyla that are diploblastic, meaning they have two germ layers during embryonic development – the ectoderm and endoderm.
How many cell layers make up the onion tissue?
There is only a single layer of cells in onion tissue. However, sometimes the tissue can fold over itself and appear to have two layers.

How many tissue layers does a hydra sea serpent have?
two layers but so have three
What members of porifera are diploblastic?
Porifera (sponges) have no specialized cells. To be diploblastic animal phyla must have a minimum of two cell layers referred to as ectoderm and endoderm. The absence of these cell types make it impossible for any members of porifera to be diploblastic.
What are 2 phyla in the animal kingdom?
There are more than two phyla in the animal kingdom... There are many phyla in the animal kingdom. There are a few phyla of worms and other invertebrates and then you have the vertebrate ohyla. Unless that's what your asking? Did you want the invertebrate and vertebrate in general phyla? That's the only set of 2 things I can think of.
What phylum has 2 layers of tissue?
The phylum Cnidaria has two layers of tissue: the outer epidermis and the inner gastrodermis separated by a jelly-like mesoglea layer. This simple body plan is characteristic of organisms like jellyfish and sea anemones.
How many life stages do cnidarians generally have?
Cnidarians have two cell layers with a jelly-like layer in between.
What is epitheleal tissue?
In biology and medicine, an epithelium is a tissue composed of cells that line the cavities and surfaces of structures throughout the body.Many glands are also formed from epithelial tissue. It lies on top of connective tissue, and the two layers are separated by a basement membrane.
What two phyla of animal contain an exoskeleton?
An exoskeleton is an external skeleton that protects and supports the animal's body. Two phyla that have exoskeletons are Arthropoda and Heterokontophyta.
