Structural Organisation Of Animals And Plants

Areolar tissue is a loose connective tissue that comprises a semifluid ground substance containing several kinds of loosely arranged fibers. It attaches the skin to the underlying tissues, filling the spaces between various organs and thus holding them in place. Areolar tissue also surrounds and supports the blood vessels.

1. The connective tissue that joins bones with bones is known as ligaments. Hence, option A is incorrect.
2. Fat bodies are connected to the muscles through adipose tissues. Hence, option B is incorrect.
3. The skin or integument is connected with the muscles through the areolar connective tissue. Hence, option C is correct.
4. Bones are connected with muscles through tendons. Hence, option D is incorrect.

So, the correct answer is Areolar connective tissue joins 'Integument with muscles'.

The correct answer is:

Option 1: Seminal vesicles

Explanation:

In male cockroaches, the seminal vesicles are the part of the reproductive system where sperms are stored after being produced in the testes. The seminal vesicles serve as a storage area for sperm before they are transferred to the female during copulation.

Here’s a brief overview of the other options:

Mushroom glands: These glands are responsible for producing a secretion that is mixed with the sperm to form the spermatophore, which is then transferred to the female.

Testes: The testes are the organs where sperm are produced, not stored.

Vas deferens: This is the tube that transports the sperm from the testes to the seminal vesicles and then to the male's reproductive organ during mating.

Thus, the correct part for sperm storage in male cockroaches is seminal vesicles.

The correct match between tissue and location is:

Option 4: Smooth muscle - Wall of intestine

Explanation:

Areolar Tissue: This type of connective tissue is found beneath the skin, around organs, and between muscles. It is not typically found in tendons. Tendons are made up of dense regular connective tissue, which provides strength and flexibility.

Transitional Epithelium: Transitional epithelium is a type of epithelium that is found in the urinary bladder, ureters, and part of the urethra. It is designed to stretch and adapt to varying volumes of fluid. It is not located at the tip of the nose.

Cuboidal Epithelium: Cuboidal epithelium is found in glands and the lining of ducts (such as sweat glands, salivary glands, etc.). It is not typically found in the lining of the stomach. The stomach lining is made up of columnar epithelium.

Smooth Muscle: Smooth muscle is found in the walls of hollow organs such as the intestines, bladder, and blood vessels. It is responsible for involuntary movements. The wall of the intestine contains smooth muscle tissue to help with peristalsis and digestion.

So, the correct tissue-location match is Smooth muscle - Wall of intestine.

Option 1: Indeterminate and radial cleavage during embryonic development

Explanation:

• Indeterminate and radial cleavage during embryonic development is a feature typically found in deuterostomes (such as echinoderms and chordates), not in Periplaneta americana (a protostome). In protostomes, the cleavage is determinate and spiral, which is different from the indeterminate and radial cleavage seen in deuterostomes.
• Exoskeleton composed of N-acetylglucosamine: Periplaneta americana (the American cockroach) has an exoskeleton made of chitin, a polysaccharide that is chemically similar to N-acetylglucosamine, so this feature is present in the cockroach.
• Metamerically segmented body: Periplaneta americana exhibits metameric segmentation, meaning its body is divided into segments, a characteristic common in arthropods.
• Schizocoelom as body cavity: The body cavity of Periplaneta americana is a schizocoelom, which is typical of protostomes like arthropods. In schizocoely, the coelom forms by the splitting of mesodermal tissue.

Conclusion:

The correct answer is Option 1: Indeterminate and radial cleavage during embryonic development, as this feature is not present in Periplaneta americana.

The correct answer is option (B): (a), (b) and (c) are correct

To solve the given problem, we need to match the items listed in List I with their corresponding descriptions in List II. Let's break down each option:

1. Taenia is a type of flatworm, and it is associated with Flame cells (III), which are involved in osmoregulation and excretion.
2. Paramoecium, a freshwater protist, uses a Contractile vacuole (II) for expelling excess water to maintain osmotic balance.
3. Periplaneta, commonly known as the cockroach, has Urecose glands (IV), which are involved in the excretion of nitrogenous waste.
4. Pheretima, known as the earthworm, utilizes Nephridia (I) to excrete metabolic waste.

Therefore, matching List I with List II gives us the mapping: A-III, B-II, C-IV, D-I.

The correct answer is: A-III, B-II, C-IV, D-I
