(a) Fig. 1.1 shows two cubes that represent a large and a small multicellular plant. Fig. 1.1 Large multicellular plant Small multicellular plant Length = 2cm Width = 2 cm Depth = 2cm Surface area : volume = 6:1 (i) Using the data provided in Fig. 1.1, calculate the surface area : volume of the large multicellular plant. Surface area: volume = ..........................................................[2] (ii) Explain why a large multicellular plant needs a transport system but a sm...
