Question
need help in this urgent 1 to 5 1. Which panels display cells that are differentiated, that is, specialized for particular functions? How many of their functions con you name? Would you argue that the amoeba s o differentiated cell, or not? 2. Which panels display cells thot ore not differentiated? As they continue to divide, will some of their descendants become differentiated? What kinds of differentiated cells will they be? 3. How many different kinds of organelles con you identify in these images? What ore their functions? 4. How do the forms of the cells n these images relate to their functions? For example, why do the two different types of blood cells hove different shapes? How about the others? 5. Using the cell diameters given n the captions, how con you determine the final magnification of each image?Explanation / Answer
1. The human red cells, the human cheek cells, the Elodea cells, and human granulocytes are specialized cells. Red cells are specialized in transport of oxygen in blood. Cheek epithelial cells form the basal mucosa of the cheek, they supply enough moisture in the mouth for enzymes to thrive.
2. Early embryos of african clawed frog, Sea urchin embryo, early zebra fish embryo, Amoeba, mouse embryonic stem cells are undifferentiated cels. Almost all of these are embryonic stem cell, can give rise to any of the differentiated cells in the organism.
3. The organelle that are clearly visible are nucleus, chloroplasts (Elodea cells), cell membranes, food vacuoles (amoeba)
4. Red blood cells are round and discoid which facilitate their free movement in small capillaries. Granulocytes are pleomorphic which no definite shape, but are generally circular. They can squeeze themselves through blood vessels and intercellular spaces due to this adaptability. MOst of the embyonic stem cells are round to have more surface to volume ration, which is characteristic of any sphere.
5. The images are 10,000 - 50,000 times magnified to their original size. This can be determined by measuring the size of each of the cell shown in the panel divided by the dimensions given below each.
