Biology 3.1.3 What is transported around plants

Substances need to be transported to all [blank_start]cells[blank_end] to allow [blank_start]metabolic[blank_end] reactions to occur and [blank_start]waste[blank_end] products need to be removed

Plants can continue to [blank_start]grow[blank_end] throughout their lives which means they can become very [blank_start]large[blank_end]. This means substances need to be transported a long way from the [blank_start]soil[blank_end] to the [blank_start]leaves[blank_end]

The plants large size results in a [blank_start]low[blank_end] [blank_start]surface area[blank_end] : [blank_start]volume[blank_end] ratio. Their [blank_start]branches[blank_end] and adaptions of the [blank_start]leaves[blank_end] help to increase the SA:V ratio

[blank_start]Water[blank_end] and [blank_start]mineral[blank_end] ions are needed from the [blank_start]soil[blank_end] via the [blank_start]roots[blank_end]

Plants need to transport [blank_start]assmilates[blank_end] as not all plant cells [blank_start]photosynthisise[blank_end] to produce [blank_start]glucose[blank_end] so the [blank_start]phloem[blank_end] transports [blank_start]sucrose[blank_end]

Xylem transports [blank_start]water[blank_end] and [blank_start]soluble[blank_end] [blank_start]mineral[blank_end] ions [blank_start]up[blank_end] the plant

Phloem transports [blank_start]assimilates[blank_end], such as [blank_start]sucrose[blank_end], around the plant (in [blank_start]all[blank_end] directions)
