The Advantage of Choosing Seeds Over Clones PowerPoint PPT Presentation
The Advantage of Choosing Seeds Over Clones - There are many advantages of choosing seeds over clones, let’s see why. STRONGER PLANTS Once a plant has germinated it develops a taproot which shoots deep down into the ground. This long root transports water together with essential nutrients into the plant so it can thrive.
