ORCHIDS, FUNGI & SYMBIOSES

Fungi grow in and on the roots of nearly all terrestrial shops, helping them absorb more water and nutrients in exchange for carbohydrates. But when fungi and orchids interact, only the orchid seems to profit. In substance, orchids come spongers, digesting fungi as a source of nutrients.
For orchids, their complex symbiotic relationship is with certain fungi called mycorrhizae. Luckily for the orchid and the fungi, the symbiosis they partake is a sweet one, substantially collective

Orchids have several life stages. The first stage is thenon-germinated orchid seed, the coming stage is the protocorm, and the ensuing stage is the adult orchid. Orchid seeds are veritably small (0.35 mm to1.50 mm long), spindle- shaped, and have an opening at the pointed end.
Each seed has an embryo that's undifferentiated and lacks root and shoot meristems. An orchid seed doesn't have enough nutritive support to grow on its own
