Question

Quizplus · Accepted Answer

The loosely packed cells with thin cell walls and numerous chloroplasts are characteristic of parenchyma cells, which are involved in photosynthesis and storage. Xylem cells have thick cell walls and are involved in water transport. The endodermis is a layer of cells in roots that regulates water and mineral uptake. Collenchyma and sclerenchyma cells have thick cell walls and provide mechanical support to plants. Therefore, the best choice is A, parenchyma cells.
