Question

Vineet prepared a slide of sunflower stem and under the microscope, he
observed that there
were seven different tissues formed of different types of cells. He
identified them as Epidermis,

Q 1. Where did he locate epidermis and cambium tissues? How are
these tissues functionally different

Answer 1

sunflower is a dicot plant.So vineet prepared a dicot stem slide.

Explanation:

• The stem's outer dermal tissue layer is the epidermis.
• The function of epidermis is to prevent damage from sunlight, pathogens, and herbivores.
• The vascular bundles of dicot stems contain a layer of meristem cells, called the cambium located between the xylem and phloem.
• The main job of the cambium is to promote growth of secondary xylem and phloem.The cells of the vascular cambium divide and form secondary xylem (tracheids and vessel elements) to the inside, and secondary phloem (sieve elements and companion cells) to the outside.
