Is it first?
Explanation:
Darwin first major break through was finding natural selection by using the pea pod method and noticing how some were yellow and some were green with different textures.
The directed movement of substances, into, out of or within a cell, either in a vascular tissue or in the vascular membrane.
The main roles of plant stems and roots are to transport substances around the plant. They have two types of transport systems – xylem and phloem . Xylem transports water and minerals. Phloem transports sugars and amino acids dissolved in water.
hope it helps because there is not any issue of transport , and if my answer i s not supportable comment i will provid emore information.
Explain that water moves down a water potential gradient, and the salt solution has a lower water potential than the vacuole so water leaves the vacuole through osmosis
In exam Q's key points are:
- Water potential gradient
- Higher water potential in vacuole
- Leaves through osmosis
