Question

Foundation biology: photosynthesisplease helpthanks

Answer 1

1.1 epidermal tissue cover the upper and lover surface of the plant
meristems are responsible for the growth at the tips of roots and shoots
xylem is the vascular tissue that transports water around the plant

1.2 can either be A or B

Palisade cells contain the chloroplasts and are responsible for the light dependent stage of photosynthesis, they are at the top of the leaf as it here were they can trap the most light and cover the most surface area to make photosynthesis more effient

Its up vertically which means that the leaf can pack in more palisade cells in a leaf and so more chloroplasts leading to a larger surface area which once again leads to more efficient photosynthesis

 The spongy mesophyll is responsible for most gaseous exchange in plants

hope that helps
