Which type of plant tissue is responsible for the increase in the length of stems and roots?
Correct Answer: A. Apical meristem
Apical meristem is found at the growing tips of stems and roots. Its primary function is to facilitate the primary growth or lengthening of the plant body. This tissue consists of actively dividing cells that contribute to the plant's height.
The flexibility in plants is primarily due to which simple permanent tissue?
Correct Answer: B. Collenchyma
Collenchyma tissue provides mechanical support and flexibility to young plant parts like petioles. The cells are characterized by localized pectin thickening at the corners. This allows plant organs to bend easily without breaking.
Which of the following animal tissues connects muscle to bone?
Correct Answer: C. Tendon
Tendons are fibrous connective tissues that attach skeletal muscles to bones. They are tough and have limited flexibility compared to other connective tissues. They play a crucial role in transmitting the force of muscle contraction to the bone.
Which complex permanent tissue in plants is responsible for the conduction of water and minerals?
Correct Answer: A. Xylem
Xylem is the vascular tissue that transports water and dissolved minerals from the roots to the leaves. It consists of four elements including tracheids, vessels, xylem parenchyma, and xylem fibers. This conduction process is largely unidirectional in the plant.
The study of the structure and organization of tissues is known as?
Correct Answer: C. Histology
Histology is the branch of biology that focuses on the microscopic study of plant and animal tissues. It involves examining how cells are organized to perform specific physiological functions. This field is essential for understanding the overall health and pathology of an organism.
Which tissue acts as a storage site for fats in the human body?
Correct Answer: B. Adipose tissue
Adipose tissue is a specialized connective tissue that stores fat in cells called adipocytes. It is located beneath the skin and around internal organs like the kidneys. Besides storage, it also acts as an insulator to prevent heat loss.
Which of the following is a characteristic of meristematic tissues in plants?
Correct Answer: B. Active cell division
Meristematic tissues consist of young, undifferentiated cells that divide continuously throughout their life. These cells have dense cytoplasm and thin cellulose walls but lack large vacuoles. They are responsible for the continuous growth observed in plants.
The internal lining of the human intestine is composed of which type of epithelial tissue?
Correct Answer: C. Columnar epithelium
Columnar epithelium consists of tall, pillar-like cells that facilitate absorption and secretion. It is found in the lining of the stomach and intestine where chemical exchange is frequent. Some of these cells may possess microvilli to increase the surface area for absorption.
Which plant tissue makes up the hard husk of a coconut?
Correct Answer: B. Sclerenchyma
Sclerenchyma is a permanent tissue made of dead cells with very thick, lignified walls. It provides great strength and rigidity to various plant parts. It is commonly found in stems, around vascular bundles, and in the shells of nuts.
The fluid connective tissue found in animals that lacks fibers is?
Correct Answer: A. Blood
Blood is a unique fluid connective tissue composed of plasma and various blood cells. Unlike other connective tissues, it does not contain structural fibers like collagen. It is primarily responsible for the transport of nutrients, gases, and hormones throughout the body.
