Within an ovule contained within an ovary of a flower b. In the style of a flower c. Enclosed in the stigma of a flower d. Packed into pollen sacs within the anthers found on a stamen Which of the following plant structures is NOT matched correctly to its function? a. Stomata allow gas transfer O b. Tracheids - allow the movement of water and minerals c. Cuticle - prevents desiccation d. Plasmodesmata - form a supportive meshwork which acts as a cellular exoskeleton
