Plant tissues class 9 biology
Grade booster・11 minutes read
Plant tissues are divided into meristematic and permanent tissues, responsible for growth and function in plants. Meristematic tissues include epical, lateral, and intercalary meristem, while permanent tissues consist of simple and complex types with various functions.
Insights
- Meristematic tissues are crucial for plant growth in specific areas like roots and shoots, continuously dividing and transforming into permanent tissues that serve various functions.
- Permanent tissues in plants are further categorized into simple and complex types, each playing distinct roles such as storage, support, nutrient transport, and water conduction, highlighting the diverse and specialized nature of plant structures.

Plant tissues: growth and function explained
- Plant tissues are divided into meristematic tissues and permanent tissues.
- Meristematic tissues include epical meristem, lateral meristem, and intercalary meristem.
- Meristematic tissues are responsible for plant growth at specific regions like roots and shoots.
- Permanent tissues are classified into simple permanent tissues (parenchyma, collenchyma, and sclerenchyma) and complex permanent tissues (xylem and phloem).
- Meristematic cells continuously divide and differentiate into permanent tissues.
- Simple permanent tissues like parenchyma store nutrients, provide structural support, and assist in photosynthesis.
- Complex permanent tissues like xylem conduct water and minerals, while phloem transports sugars and nutrients.
- Epidermis is the outer protective covering of plants, with different types for aerial and root parts, featuring structures like cuticle, stomata, and root hairs.
