Without stomata, plants could not exchange gases or perform proper transpiration. Photosynthesis, respiration and cooling would be affected. Water transport through transpiration pull would reduce, disturbing growth, food preparation and overall survival of the plant.
Various body parts are connected by connective tissues such as blood, bones, cartilage, tendons and ligaments. These tissues support organs, transport materials, connect muscles and bones, stabilise joints and maintain proper coordination throughout the body.
Rohan’s statement is correct for simple tissues because they contain similar cells performing one function. Rajiv is also correct because complex tissues contain different types of cells working together for a common function, like xylem and phloem.
