Question 5
Palisade parenchyma and spongy parenchyma are found in a leaf. What do both of them do?
The right answer is the one marked above.
Carry out photosynthesis, because both contain chloroplasts. They are two arrangements of the same tissue — palisade cells tall and upright near the upper surface, spongy cells looser with air spaces below.
Transporting food is the job of phloem, and supporting a leaf blade is done by the collenchyma in its veins.
