What are triploblastic organisms?

What are triploblastic organisms?

Function of Triploblastic Triploblasts are organisms whose body is derived from all three germ layers, which are the endoderm, mesoderm, and ectoderm. Ectoderm forms the brain, spinal cord, lens of the eye, and hairs.

What are the examples of triploblastic animals?

Examples of triploblastic animals include platyhelminthes, annelids, arthropods, molluscs, echinoderms, and chordates.

Which of the following groups are Diploblastic?

Groups of diploblastic animals alive today include jellyfish, corals, sea anemones and comb jellies.

How do you identify a triploblastic animal?

Bilaterally symmetric animals are triploblastic. They produce the three germ layers: endoderm, ectoderm and the mesoderm. The key difference between diploblastic and triploblastic animals is that diploblastic animals produce two germ layers excluding mesoderm and triploblastic animals produce all three germ layers.

What are triploblastic animals Class 9?

Triploblastic animals are those which have three germ layers in the embryo. The outer layer is called ectoderm, the inner layer is called endoderm and the middle layer is called mesoderm. Animals of phylum Platyhelmithes, such as Planaria and blood fluke.

Which kind of animals are diploblastic?

Groups of diploblastic animals alive today include jellyfish, corals, sea anemones and comb jellies. Coelenterates like jellyfish, corals, sea anemones and comb jellies are animal groups which are diploblastic. They have a body wall composed only of two layers, ectoderm and endoderm.

Which of the following animal phyla are diploblastic?

Diploblastic animals only have two germ layers: the inner endoderm and the outer ectoderm. Animals in the phyla Cnidaria and Ctenophora are diploblastic. The majority of invertebrates also have a third germ layer called the mesoderm (Fig.

What is triploblastic and diploblastic?

Diploblastic: Animals in which the cells are arranged in two embryonic layers, external ectoderm, and internal endoderm, are called diploblastic animals, for example, coelenterates. Triploblastic: An animal possessing 3 major tissue layers. It has a central layer (the mesoderm), between the endoderm and the ectoderm.

What is the difference between a monocyte and a monoblast?

The monoblast in the lower right has abundant cytoplasm, vacuoles and pseudopods which may lead to misidentifying it as a monocyte. However its nuclear features (large rounded nuclei with prominent nucleoli and fine chromatin) are characteristic of a monoblast.

What is the prevalence of acute monoblastic leukemia (AML)?

Acute monoblastic leukemia comprises 5-8% of cases of AML. It may occur at any age but is most common in young individuals. In infancy, it is frequently associated with abnormalities of 11q23. Extramedullary lesions may occur. Acute monocytic leukemia conmprises 3-6% of cases; the male to female ratio is 1.8 to 1.0.

What is the cytochemistry of monoblasts and promonocytes?

Cytochemistry: Monoblasts are typically MPO negative and promonocytes are MPO variable. Both monoblasts and promonocytes stain positive for non-specific esterase (NSE), however NSE may often be negative.

What is the difference between promonocytes and monocyticleukemia?

By contrast, promonocytes have a more convoluted nucleus, and their cytoplasm may contain metachromatic granules. Example morphology of acute monocyticleukemia case.
