Answer 2

long and narrow with parallel veins (monocots), broad with branched veins (dicots)

Question 3

Question 6

List the functions of roots

Answer 6

water and nutrient absorption, anchorage, storage of nutrients

Question 7

Describe the structure of the root

Answer 7

epidermis -> cortex (parenchyma) -> endodermis (modified parenchyma) -> stele (vascular bundle)

Question 8

What is the function of the cambrium?

Answer 8

Separates xylem and phloem
