Nov 25, orchids growing on tree branches because a commensalism relationship is when one benifits and one not benifited nor harmed. orchids. According to the Brooklyn Botanic Garden, there are between and 30 Orchids that grow on a host tree have a special kind of symbiotic relationship with . Epiphytic orchids can also be found perched in trees in the rainforest; like bromeliads, they Now let's look at some less benign relationships between plants.
Amensalism is the type of relationship that exists where one species is inhibited or completely obliterated and one is unaffected. Autumn Flowering Laelia, Laelia autumnalis Miltassia sp. For orchids, their complex symbiotic relationship is with certain fungi called mycorrhizae. Luckily for the orchid and the fungi, the symbiosis they share is a sweet one, mostly mutual.
What is relationship between orchid and tree
Orchid mycorrhiza is the symbiotic process wherein juvenile orchids rely on special fungal symbionts to supply them with carbohydrates and in exchange the fungi receive moisture and access to organic matter. The roots of an orchid are full of moisture, and often surrounded by organic plant material—the perfect environment for fungi.
The majority of orchids grow in habitats where sunlight is limited think shadowy mountainsides. Without sunlight it is nearly impossible for the orchids to produce chlorophyll their version of Vitamin D.
Because the orchids cannot produce enough chlorophyll, they depend on specific fungi to assist them. The fungi can digest organic matter that occurs in the surrounding area, converting it into simpler molecules such as sugar that the orchid can absorb.
Pansy orchid, Miltonia phalaenopsis The young orchid is so reliant on the fungi that it must wait for the fungi to invade its seeds before the orchid even begins to germinate. During this invasion the fungi obtains nutrients from the host plant, while the orchid seeds receive a fungal energy boost carbon. All orchids depend on mycorrhizae at some stage in their life-cycle.
Orchids rely on the fungus as they begin to grow, but as they mature some species begin to produce their own food source. Some orchids become photosynthetic, meaning they can produce their own organic carbon. While botanists are still researching this complex relationship, it appears that even orchids which are photosynthetic may still use the fungi as a back-up food source.
The corn plants grew straight and tall, giving the pole beans something to climb on. The beans, since they are legumes, contributed nitrogen to the soil. And the pumpkins shaded out competing weeds.
And even something as simple as the relationship of a tree to the groundcover beneath it can be considered a beneficial, plant-plant relationship. The tree casts shade, providing habitat for a shade-loving groundcover, and the groundcover in turn keeps more deep-rooted and competitive grasses at bay. One interesting group of plants are the epiphytes.
Relatively rare in temperate regions, epiphytes are quite common in tropical rainforests. An epiphyte is a plant that grows on another plant, neither harming nor helping it.
For example, mosses can be epiphytic, growing harmlessly on tree trunks. More exclusively epiphytic plants are the bromeliads and some orchids.

Bromeliads are plants that commonly grow high in the branches of tropical rainforest trees. They are often found in the joint where a branch meets the trunk; there, fallen plant debris collects, providing a source of nutrients to the bromeliad.
Some species of bromeliad have cup-shaped leaf rosettes.
