They resemble animal cells and contain major organelles and the cell nucleus. All of the following are found in some or all protozoa except: John David Jackson, Patricia Meglich, Robert Mathis, Sean Valentine. Some of the types are: 1. . Endoplasm also contributes to the locomotion of the amoeba. Endoplasm Protozoa are eukaryotic; some have multiple nuclei. Not to be confused with the cytoplasm, the cytosol is only the gel matrix of the cell which does not include many of the macromolecules essential to cellular function. Sub-order: Nuda Body naked or enclosed in a thin membrane. What are 5 characteristics of amoeba?

None of the choices is correct. Protoplasm contains two nuclei, two axostyles and two parabasal bodies. (i) T. gambiense parasitizes man in Central Africa causing sleeping sickness disease. Amoeba cells locomote by pseudopodia formation. . Endoplasm appears more granular and contains the nucleus and cytoplasmic organelles. In most protozoa the cytoplasm is differentiated into ectoplasm (the outer, transparent layer) and endoplasm (the inner layer containing organelles); the structure of the cytoplasm is most easily seen in species with projecting pseudopodia, such as the amebas. Select one: a. ectoplasm b. mitochondria c. agella d. oral grooves e. cilia 0 So, they eat by surrounding tiny particles of food with pseudopods, forming a bubble-like food vacuole digests the food Minicircles * The height of a kinetoplast disk is about half the circumference of a minicircle.

There are many different types, characterized by the substance that the vesicle contains. These granules give the cell a large amount of regulation and control over the wide variety of metabolic activities that take place within the endoplasm. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle. The different makeups/viscosities of the endoplasm and ectoplasm contribute to the amoeba's locomotion through the formation of a pseudopod. It is clearly visible in the amoeba cell. Amoebozoa is ranked as a phylum in Kingdom Protista 1 (or Kingdom Protozoa) 2. Our mission is to provide an online platform to help students to discuss anything and everything about Zoology. .

Organisms that live in a liquid environment with a lower concentration of ions than is found in the interior of their cellsan osmotically hypotonic environmentgradually gain water if they equilibrate with their habitat. Ectoplasm occupies a small region of the cell. In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Cryptomonas 3. 6. . Endoplasm is the site of most cellular processes. Ectoplasm usually contains more actin filaments to support cell membrane for elasticity. Mastigamoeba 8. Almost all protozoans contain double-membrane mitochondria; the inner membrane forms flattened, tubular, or discoidal extensions (cristae) into the mitochondrial interior in order to increase the surface area of the respiratory machinery, and the outer membrane forms the boundary of the organelle.
