Apical meristem is located at the growing tips of stems and roots and is responsible for increasing the length of the stem and the root by producing new cells through cell division.

Meristematic tissues are classified as apical, lateral, and intercalary depending on where they are present in the plant.

Plant growth is limited to specific regions because those regions contain meristematic tissue, also known as dividing tissue, which is responsible for cell division and subsequent growth.

Adaptation for sedentary existence in plants leads to the development of specialized tissues for anchorage, nutrient absorption, and photosynthesis, whereas adaptation for active locomotion in animals necessitates complex organ systems for movement, sensory perception, and efficient energy utilization.

Tissues, which are groups of cells with similar structure and function, are more intricately organized and diversified in complex animals to support their specialized organ systems, whereas in plants, tissues primarily serve functions related to growth, support, and nutrient transport.
