Plant and Animal Tissues

Answer

A tissue is a group of cells that are similar in structure and perform a specific function. For example, skin cells form a protective tissue, and muscle cells form muscle tissue.

Answer

Multicellular organisms need tissues because many similar cells working together can do a job more efficiently than single cells alone. Tissues help in forming organs and organ systems.

Answer

Meristematic tissues are plant tissues made up of actively dividing cells. Their only function is to produce more cells, which helps the plant grow.

Answer

Meristematic tissues are found at growing points such as the tip of roots, stems, and branches. These regions help the plant grow in length, and meristematic tissue also helps in growth in thickness o…

Answer

Meristematic tissue cells are small, thin-walled, have large conspicuous nuclei, and almost no vacuoles. They divide actively to form new cells.

Answer

Permanent tissues are non-dividing plant tissues that form the bulk of the plant body. Their cells have stopped growing for the time being or completely and are specialised for different functions.

Answer

Permanent tissues are classified into two main types: simple permanent tissue and complex permanent tissue. Simple permanent tissue mainly provides support and protection, while complex permanent tiss…

Answer

Parenchyma is a simple permanent supporting tissue made of large, thin-walled living cells with intercellular spaces. It stores food, gives temporary support, and some cells contain chlorophyll for ma…
