regarding plants what is incorrect?
1 the photosynthetic mesophyll is made up of an upper spongy layer and a lower palisde layer

2 the epidermis is covered by a waxy layer of cuticle that reduces water loss

3 gas exchange occurs through tiny openings in the leaf surface called stomates

4 vascular tissue is arrenged in a net pattern in dicots and parallel pattern in monocots

5 regulation of gas exchange through the leaf is the responsability of the guard cells

im between two answers but not sure about it,

well i know for sure is not number 3 i know stomates is an structure where occurs gas exchange, and number 2 either the epidermis is covered by a cuticle to minimize water loss, and number 5 is correct the stomas has a small pore in de epidermis and is bordered by guard cells
so im between number 1 and 4 ????????

Number 4 is correct and number 1 is incorrect because the photosynthetic mesophyll is made up of an upper palisde layer and a lower spongy layer
