Why do Plants need a specialised transport system

Whats the first reason for plant transport systems

Metabolic demands : Many internal and underground parts do not photosynthesise. They need these transporting to them, and to also remove waste products

Whats second reason for plant transport systems

SA:V . Plants cannot rely on diffusion alone to supply cells with what they need. Although leaves have a relatively large SA:V, when the stem and leaves are taken into account, they have a small SA:V ratio

Whats third reason for plant transport systems

Size : Many plants can get very large and so need a substantial transport system.

What do seeds contain

An embryonic leaf called a cotyledon, when seed germinates, the cotyledon unfurls , allowing the seed to carry out photosynthesis.

What are examples of dicotyledonous plants

Geranium (Herbaceous) and Oak tree (Woody).
