Answers
Answer:
In biology, tissue is a cellular organizational level between cells and a complete organ. A tissue is an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function. Organs are then formed by the functional grouping together of multiple tissues.
Answer : Worksheet -1
Q1. A group of similar cells more or less alike in size and shape having a common origin and performing the same function.
Q2. Meristematic tissues and Permanent tissues
Q3. Meristematic tissues are found at the growing parts of the plant body such as root, shoot and leaves.
Q4. meristematic tissue divide continuously on a help increasing length and girth of plant.
• meristematic tissue continuously divided form a number of new cell .
Q5. Permanent tissue develope from the new cell formed by the division of meristematic tissue, the cell of permanent tissue are much larger and do not divide further, hence they are called permanent issues.
Q6. Simple permanent tissues and Complex permanent tissues.
Q8. Parenchyma
