Companion cells are adapted for mass flow by having numerous mitochondria for ATP production for active transport and abundant ribosomes and RER to synthesize carrier proteins for both active transport and facilitated diffusion of sucrose.
- large number of mitochondria - to produce more ATP by aerobic respiration - for active transport of sucrose - large number of ribosomes and RER - to synthesise more carrier proteins - for active transport and facilitated diffusion of sucrose
