The major methods of asexual propagation are cuttings, layering, division, budding and grafting. Cuttings involve rooting a severed piece of the parent plant; layering involves rooting a part of the parent and then severing it; and budding and grafting is joining two plant parts from different varieties.

Plant organisation. Plant cells, tissues and organs are adapted to their functions. The stem, root and leaves form an organ system that transports substances into, around and out of a plant.

In plants there are two modes of reproduction, asexual and sexual. There are several methods of asexual reproduction such as fragmentation, budding, spore formation and vegetative propagation. Sexual reproduction involves the fusion of male and female gametes.

The cellular respiration process includes four basic stages or steps: Glycolysis, which occurs in all organisms, prokaryotic and eukaryotic; the bridge reaction, which stets the stage for aerobic respiration; and the Krebs cycle and the electron transport chain, oxygen-dependent pathways that occur in sequence in the ...
