Question

Answer

Laticiferous tissues are made up of thin walled, elongated, branched and multinucleate (coenocytic) structures that contain colourless, milky or yellow coloured juice called latex. These occur irregularly distributed in the mass of parenchymatous cells.

Answer

Tissues secreting latex are Laticiferous

The correct answer is option 'A', laticiferous. Laticiferous tissues are specialized plant tissues that secrete latex, a milky or resinous substance. These tissues are found in various parts of the plant, such as stems, leaves, roots, and fruits. Latex serves various functions in plants, including defense against herbivores, wound healing, and protection from pathogens.

Characteristics of laticiferous tissues:
1. Presence of specialized cells: Laticiferous tissues consist of elongated cells called laticifers that are responsible for the secretion of latex. These cells are characterized by their large size, thin walls, and abundant cytoplasm.

2. Intercellular spaces: Laticiferous tissues often have intercellular spaces between the laticifers, allowing the latex to flow and accumulate within the tissue.

3. Latex vessels: Laticifers are connected to form a network of latex vessels or ducts that transport the latex throughout the plant.

4. Latex composition: Latex is a complex mixture of various organic compounds, including proteins, carbohydrates, alkaloids, terpenoids, and phenolic compounds. The composition of latex can vary between plant species and even within different parts of the same plant.

Functions of latex:
1. Defense against herbivores: Latex contains toxic or deterrent compounds that can repel or immobilize herbivores. When a plant is damaged, latex is released to deter further feeding or to trap and immobilize herbivores.

2. Wound healing: Latex plays a role in wound healing by sealing off injured areas and preventing the entry of pathogens. It forms a protective layer over wounds, helping to prevent infection and promote tissue regeneration.

3. Protection from pathogens: Some components of latex, such as alkaloids and phenolic compounds, have antimicrobial properties and can help protect the plant from pathogens.

4. Storage of secondary metabolites: Latex can serve as a storage site for secondary metabolites produced by the plant. These compounds may have various functions, such as attracting pollinators, deterring herbivores, or aiding in plant defense.

Overall, laticiferous tissues and the latex they produce play important roles in the survival and defense of plants.
