Name the cells in section I

Which option best describes the upper epidermis layer?

• a layer of closely packed cells below a layer of waxy cuticle

• layers of closely packed cells that contain numerous chloroplasts

• layer of irregularly shaped cells with numerous large intercellular air spaces

• Single layer of closely packed cells with any minute openings called stomata

Name the cells in section II

Which option best describes the palisade mesophyll layer?

• Single layer of closely packed cells with any minute openings called stomata

• layers of closely packed cells that contain numerous chloroplasts

• layer of irregularly shaped cells with numerous large intercellular air spaces

• contains the xylem and phloem

What is the main function of the palisade mesophyll cells?

• transport of water and food materials within the plant

• allow rapid diffusion of gases inside the leaf

• photosynthesis

• allow gaseous exchange in and out of the leaf

Name the cells in section III

Which option best describes the vascular bundle?

• Single layer of closely packed cells with any minute openings called stomata

• layers of closely packed cells that contain numerous chloroplasts

• layer of irregularly shaped cells with numerous large intercellular air spaces

• contains the xylem and phloem

What is the main function of the vascular bundle?

• transport of water and food materials within the plant

• allow rapid diffusion of gases inside the leaf

• photosynthesis

• allow gaseous exchange in and out of the leaf

Name the cells in section IV

Which option best describes the spongy mesophyll?

• Single layer of closely packed cells with any minute openings called stomata

• layers of closely packed cells that contain numerous chloroplasts

• layer of irregularly shaped cells with numerous large intercellular air spaces

• contains the xylem and phloem
