What would happen if liver cells did not have SER |
|
Answer» In contrast to the RER, smooth endoplasmic reticulum lacks ribosomes and is not involved in protein synthesis. Note that the lack of ribosomes means that the smooth ER is not basophilic and usually stains POORLY by H&E. The MAIN functions of SER are the biosynthesis of phospholipids and cholesterol and the synthesis and repair of membranes. It also possesses some tissue-specific functions: in the liver, the SER contains LARGE amounts of cytochrome P450 and participates in the detoxification of metabolic waste products, drugs, and alcohol; in the muscle, the SER is known as the sarcoplasmic reticulum and stores and releases calcium ions needed for muscle contraction. Although the composition and function of the smooth ER is different than the ROUGH ER, they are continuous with each other. In what types of cells, besides liver and muscle, would you expect to FIND large amounts of smooth ER? |

Write four flight adaptation in aves |
|
Answer» Flight adaptation in aves We generally imagine about having wings and flying to see the world from the high level. Though naturally we have no such modification in the body but the development of TECHNOLOGY have made it possible to fly above the ground level and take a view of natural environment. Besides this, reaching to the desired destination within short time period have becomes easier with the invention of these technological mediums. Though we lack wings and structure that benefits us in flying, but there are certain groups of animal that have well developed body PLAN to make the flight possible above the earth. Animals that come under this group have well modified body that makes them easy to soar above the ground. Hence, they come under one class of vertebrates called Aves. The classifications for aves are as follows: Kingdom: animalia Phylum: chordate Class: Aves Hence, this is the major classification of Aves beside this; it is divided into two orders called Passeriformes and Galliformes. Further, Passeriformes is again sub-divided into different groups.  There are certain characteristics that make this class of animals different from the others in various respects. Some of the visible characteristics of this class are: We commonly dignify them as birds. They are warm blooded animals. They have a pair of legs to move on the ground. The presence of exoskeleton in the surface of the body. Body divided into HEAD, long neck, trunk and tail. The neck is long in order to maintain the balance of the body. 2 pairs of limbs are present. Forelimbs are modified for flying whereas hind limbs have legs that help birds to move on the ground whenever necessary. Sexes are separate. Well developed nervous system. Endothermic Presence of four chambered heart for circulation. BONES are light and not very heavy for balancing the body. Absence of teeth. Communication through unusual sound or singing. Well developed parental care These are some of the characteristics that can be noticed in Aves that keeps these groups of chordates in separate class. Flight Adaptation in birds: Effective flight is possible only when two requirements are met, light weight of the body and the supply of energy. Hence, the organs that are modified for effective flight are: Birds have short body with compact bones. This reduces the weight of the body and makes it light. There are different kinds of feathers present in birds: outline feather helps to decrease the drag of the body by making it streamlines; primary feathers helps to provide shape to the wings and make the flight possible; tail feather are used as RUDDER for balance of the body. Bones in birds are either hollow or fused to reduce the weight of the body. The fusion of caudal bone to form pygostyle and hollow bones of skull are good example of it. Absence of teeth and present of beak is also one of the important adaptations for flight in birds. |
