Test: Tissues in Action - 1 - Question 1
Save

Which type of meristematic tissue is responsible for increase in the length of a plant?

Detailed Solution: Question 1

Apical meristems are located at the tips of roots and shoots. They contain actively dividing cells that are responsible for the increase in length (height of stem and depth of roots) of the plant. When the tips are cut, as shown in the onion bulb experiment, roots stop growing, confirming this.

Save

Annual growth rings visible in a cut tree trunk are formed due to the activity of which tissue?

Detailed Solution: Question 2

The lateral meristem is a ring of actively dividing cells in the stem of dicot plants. These cells divide and produce new cells inward and outward in a concentric manner, increasing the diameter of the stem. Each year's growth forms a visible ring, and by counting these rings scientists can estimate the age of a tree.

Grass grows back after mowing or grazing by animals. Which type of meristematic tissue is responsible for this?

Detailed Solution: Question 3

The intercalary meristem is located at the base of the internode or just above the node. When the tip of a young stem is cut, the stem stops growing in length but new branches arise from the nodes due to intercalary meristem activity. This is why grass grows back after mowing and hedges become bushy after cutting.

Test: Tissues in Action - 1 - Question 4
Save

Which of the following is NOT a characteristic of meristematic tissue cells?

Detailed Solution: Question 4

Meristematic cells are specially adapted for continuous, rapid cell division. They are small in size, have thin cell walls, a large and prominent nucleus, and dense cytoplasm with many organelles. Vacuoles are absent in meristematic cells because they would use up the space needed for cell division. A large central vacuole is a feature of mature plant cells, not meristematic cells.

Test: Tissues in Action - 1 - Question 5
Save

Which simple permanent tissue provides support and flexibility to stems and tendrils, allowing them to bend without breaking?

Detailed Solution: Question 5

Collenchyma consists of living cells with unevenly thickened corners due to pectin deposition. This structure provides both support and flexibility, allowing stems and tendrils to bend without breaking. It is found at the periphery of stems and in leaf stalks. Sclerenchyma, on the other hand, provides rigidity but no flexibility as its cells are dead with thick lignin-deposited walls.

Test: Tissues in Action - 1 - Question 6
Save

Which of the following is the only living component of xylem?

Detailed Solution: Question 6

Xylem consists of four types of cells — tracheids, vessels, xylem parenchyma, and xylem fibres. Tracheids, vessels, and xylem fibres are all dead cells with thick walls. Xylem parenchyma is the only living component of xylem. Phloem, which transports food, is mostly made of living cells.

Test: Tissues in Action - 1 - Question 7
Save

Which cells in the phloem regulate the loading and unloading of sugars into sieve tubes?

Detailed Solution: Question 7

Companion cells are specialised parenchyma cells associated with sieve tubes in the phloem. They regulate the cellular functions of sieve tubes and monitor the loading and unloading of sugars. Sieve tubes themselves are long tubular cells joined end to end with perforated walls that transport food. Phloem parenchyma stores food materials like resin, tannins, and latex.

Test: Tissues in Action - 1 - Question 8
Save

The waxy layer covering the epidermis of plants is called the cuticle. What is its primary function?

Detailed Solution: Question 8

The epidermis is the outermost protective layer of the plant body. The cells are covered by a waxy layer called the cuticle, which reduces water loss and provides protection against physical damage and microbes. In plants growing in dry habitats, the cuticle may be very thick to further prevent water loss.

Test: Tissues in Action - 1 - Question 9
Save

Which tissue system in plants consists of parenchyma, collenchyma, and sclerenchyma?

Detailed Solution: Question 9

Plants are organised into three tissue systems. The dermal tissue system forms the outer covering (epidermis). The vascular tissue system consists of xylem and phloem. The ground tissue system forms the main body of the plant between the dermal and conducting tissues, and includes parenchyma, collenchyma, and sclerenchyma.

Test: Tissues in Action - 1 - Question 10
Save

Which type of epithelial tissue is best suited for rapid diffusion of gases and liquids, such as in the lining of blood vessels and lungs?

Detailed Solution: Question 10

Epithelial tissue suited for rapid exchange of gases and liquids is made of a single layer of thin, flat cells. This thin structure allows substances to diffuse quickly across it. This type lines the blood vessels and lungs. In contrast, the skin has many layers of flat cells for protection, and the small intestine lining has tall cells for absorption.

Test: Tissues in Action - 1 - Question 11
Save

Root hair cells are extensions of which tissue, and what is their primary function?

Detailed Solution: Question 11

Root hair cells are hair-like projections that arise from the epidermal cells of roots. The epidermis is the outermost protective layer of the plant body. Root hairs significantly increase the surface area available for absorption of water and minerals from the soil. Along with the selective permeability of the cell membrane, the permeability of the cell wall helps plant roots absorb nutrients efficiently.

Test: Tissues in Action - 1 - Question 12
Save

A student observes two types of cells under a microscope. Cell A is spindle-shaped with a single nucleus and no striations. Cell B is long, cylindrical, unbranched with multiple nuclei and clear light and dark bands. Which of the following correctly identifies them?

Detailed Solution: Question 12

Smooth muscle cells are spindle-shaped, have a single nucleus, and show no striations. They are involuntary and found in organs like the stomach and intestines. Skeletal (striated) muscle cells are long, cylindrical, and unbranched with multiple nuclei and clear light and dark bands (striations). They are voluntary muscles attached to bones that enable movement and locomotion.

Test: Tissues in Action - 1 - Question 13
Save

Which of the following statements correctly explains why mature RBCs lack a nucleus while neurons retain theirs?

Detailed Solution: Question 13

Mature RBCs lack a nucleus because its absence provides more internal space for haemoglobin, allowing them to carry more oxygen. However, this means they cannot repair or divide themselves, giving them a lifespan of only about 120 days. Neurons, on the other hand, retain their nucleus in the cell body because it controls the cell's activities, including the reception and transmission of nerve signals throughout the body.

Test: Tissues in Action - 1 - Question 14
Save

In F. C. Steward's experiment, carrot phloem cells were able to regenerate an entire plant. What property of plant cells does this demonstrate?

Detailed Solution: Question 14

Totipotency is the ability of a mature plant cell to dedifferentiate, divide, and redifferentiate into a complete new plant under suitable conditions. F. C. Steward demonstrated this in 1958 by growing individual phloem cells from carrots in a nutrient medium. The cells first formed an undifferentiated mass and then developed into a complete plant. This is similar to the ability of a zygote to divide and differentiate into an entire organism.

Test: Tissues in Action - 1 - Question 15
Save

Which of the following pairs correctly matches a connective tissue with its matrix type?

Detailed Solution: Question 15

Blood is a connective tissue with a fluid matrix called plasma, which contains RBCs, WBCs, and platelets. Bone has a rigid matrix containing calcium and phosphorus compounds. Cartilage has a soft, jelly-like matrix that cushions bone ends. Tendons are tough connective tissues that connect muscle to bone — they do not have a fluid matrix. The nature of the matrix determines the physical properties of each connective tissue.
