The cells are derived from the walls of the embryonic cavities. The fifth abdominal ganglia located at the junction of the fifth and sixth segments is largest and occupies the terminal position of the nerve cord. In short their homologies are very obscure.3 We have stated that in the Gymnosomata there exists in a constant manner two pairs of tentacles properly so called. 2, 4, and 7) The "lips" situated between the cones of Clione are not then equivalent to the lips of the other Gymnosomata, in which there is no developed hood like that of Clione. The conglobate gland is as­sociated with the ejaculatory duct. Without prejudging anything as to the morphological value of these appendages, I believe that they have the same origin, however varied their aspect may be in the three genera above named. Based on the inclination of long axis of the head and orientation of mouth parts there are three types of insect heads. Nerves arising from the ganglia of the central nervous system constitute the pe­ripheral nervous system.

Which of the following is NOT reason why insects are the most successful group of land animals on earth? Each vas deferens, before uniting with its fellow of the opposite side, dilates a little forming a seminal vesicle, from which arise a large number of blind pouches and the whole arrangement is known as mushroom gland. The styles of male and the gonapophyses are possibly relics of appendages. vii. Formed by the fusion of three pairs of ganglia associ­ated with the segments that produce mouth appendages and located in the head below the oesophagus. 25.28). Ten pairs of respiratory apertures called stigmata, two in the thorax and eight in the abdomen are present on the sides of the body. By Paul Pelaeneer, ».S©BS Brussels. Spermatophores packed with sperms 0are transferred to female during mating and the sperms are temporarily stored in the spermathecae. The aorta runs forward along the dorsal surface of the oesophagus and ends in front of the peripharyngeal nerve ring in the form of a funnel. A pair of five jointed legs are at­tached to the sternum of each of the thoracic segments. The different authors agree but little on the cephalic appendages of the gymnosomatous Pteropoda, and many of them consider all these appendages as tentacles. C. Femur. It consists of two bands of tissues that cross in the form of ‘X’: The anterior arms of the cross are relatively long, the overall length being 3.0 ± 2.0 mm. The different authors agree but little on the cephalic appendages of the gymnosomatous Pteropoda, and many of them consider all these appendages as tentacles. MEDIUM. It represents a) tergum of the first abdominal segment b) sternum of the first abdominal segment c) tergum of the first thoracic segment d) sternum of the first thoracic segment 5. The first pair communicate with the ventral nerve cord. The maxillae procure the food, the mandibles cut it into pieces and the food is taken into the buccal cavity. Nereis, scorpion, cockroach and silver fish are all invertebrates and thus possess dorsal heart. They would be a differentiation of the internal wall of the buccal cantys which is prodnced behind the buccal appendages. The following points highlight the nine important larval forms found in Crustacea. The German cockroach is particularly successful for the following reasons: 1. 25.25).

The rectum opens to the exterior through anus, provided with a sphincter muscle, be­tween two podical plates at the posterior end. This pair of tentacles is, in my opinion, equivalent to the oculiferous nuchal pair of the Gymnosomata. The coxae appear flattened (as in extant cockroaches)—best shown in the left midleg (figure 2 c), which also displays the trochanter. NCERT Exemplar Class 11 Biology Chapter 4 Animal Kingdom are part of NCERT Exemplar Class 11 Biology.

There are other traits that are … The secretion ini­tiates moulting, occyte formation and devel­opment of secondary sexual organs. The tergites of these segments have fused to form a head capsule. 25.32A). From the posterior end of the ovariole runs a narrow tubule and by the union of tubules coming from all the ovarioles of an ovary, a wider tube, the oviduct is formed. Mandibles, 1st maxillae, 2nd maxillae and hypo pharynx constitute the mouth parts. Each gland consists of two leaf-like glands, made of diffused lobes. In young cockroach, the vertex is divided by an inverted Y-shaped epicranial suture into two epicranial … Sea star, tongue worm, scorpion 4.

Pronatum is a shield-like hard struc­ture present on the dorsal surface of the prothorax. The nerve cord bears nine pairs of ganglia, three pairs in the thoracic segments and six pairs in the first six abdominal seg­ments. They are tactile sense organs. 33). It is terrestrial, nocturnal, cursorial (fast runner), omnivorous and unspecialized insect. I do not think it will be rash to identify these appendages with the two pairs which the Gastropoda Euthyneura (Opistho-branchia and Pulmonata) possess, and which occupy the same position among these animals as with the Gymnosomata. joe interbreeds these selected cockroaches. (2011) for the cephalic musculature, and Buder & Klass (2013) for exoskeletal elements of the hypopharynx (which are . Besides the two pairs of tentacles properly so called, we have seen that most of the Gymnsomata possess buccal appendages; such are Clione, Pneumodermon, Cirrifer. The abdomen gradually narrows down posteriorly. A more flexible pair of jaws, the first maxillae, are situated behind the mandibles. 2014a). A large number of eggs per capsule 2.

The two are joined by connectives and also connected to a median hypo-cerebral ganglion. The cockroach’s response to the attack had two stages: an abrupt turn away from the toad that started well before the tongue came out, and then 50–70 ms later, running away (Figure 1). It maintains equilibrium of the animal. Presence of endocellular symbiotic Blattabacterium; Blattabacterium are common to most cockroaches and are necessary for their survival. D. Coxa. The haemolymph bears no respiratory pigment and, as such, it is not concerned with respiration. 4. With Plate XXXV.

Sixteen fertilized eggs cure enclosed in a case, the Ootheca, formed by the secretion of the colleterial glands. NCERT Exemplar Solutions of Class 11 Biology Chapter 4 Animal Kingdom. From each spiracle leads inward a small tube which ends in a stout trachea and all of them are connected by longitudi­nal and transverse tracheae. The food is crushed by the teeth and the hairy cushions permit only finer food par­ticles pass to the midgut. 2. Two types of cells—bi-nucleated and with elongated nucleus, are present in the fat bodies. 4. So the correct option is D. Answered By . At the same time it must be remembered that this front portion of the buccal cavity may be regarded as not part of the true oral cavity, but as only an "introvert" like that of proboscidiferous Gastropods. It extends into the abdomen. (2014a) for general exoskeletal morphology, wiPfler et al. By the successive contraction of the chambers of the heart, haemolymph is driven forward and poured in the haemocoel through the aorta. Paired nerves from each abdominal ganglion end in the organs of the corresponding segment. Organ level B. honey bee 3. The cephalon carries the antennula as the most anterior appendage. Each leg consists of five segments, coxa, trochanter, femur, tibia and a six-jointed tarsus ending in a pair of claws (Fig. Nitrogenous wastes are absorbed by the cells from the haemolymph and the same are discharged into the lumen of the tubule which, in turn, convey the wastes into the lumen of the intestine. d.
