Following are the characteristics of a plant tissue.I. It has angular thickening in its primary cell wall.II. It provides support to young herbaceous parts of the plant.The plant tissue with these characteristics is identified as
Correct answer: D. Collenchyma
- A. Sclereid
- B. Tracheid
- C. Parenchyma
- D. Collenchyma
Explanation
The correct answer is collenchyma. Collenchyma tissues are specialized for providing support to young, growing parts of the plant, such as stems and leaves, which aligns with the characteristic of providing support to young herbaceous parts. They are characterized by their uneven or angular thickening of the primary cell walls, which helps them support and strengthen these parts without hindering growth.On the other hand, sclereids are a form of sclerenchyma with heavily lignified walls, contributing to hardness and rigidity, not the flexible support described. Tracheids are involved in water transport and structural support but do not match the description of angular thickening or support specifically for young herbaceous parts. Parenchyma cells are generally thin-walled and involved in various functions like storage and photosynthesis, not specifically support with angular thickening.

About Plant Nutrition and Transport
Plants require macronutrients and micronutrients for growth, and mineral deficiencies produce recognizable symptoms. Transport involves water and minerals through xylem by transpiration pull, cohesion and adhesion, while phloem translocates sugars from sources to sinks. Root pressure and transpiration are distinct mechanisms.
