Question

What are the two ways of incorporating desirable characteristics in crop varieties?

Answer 1

Explanation:

There are three main types of passive transport:

Simple diffusion – movement of small or lipophilic molecules (e.g. O2, CO2, etc.)

Osmosis – movement of water molecules (dependent on solute concentrations)

Facilitated diffusion – movement of large or charged molecules via membrane proteins (e.g. ions, sucrose, etc.)
