How do orchids adapt or how have they adapted to the tropical rain forest?

Question

I know I should do my own homework, I'm just looking for some alternate ideas to the ones I have already found.

Answer 1

They fall on branches and with the aid of some fungi germinate, so they feed on fungi by-products, so they don't need large seeds. They are called epiphytes living on the surface of tree's trunk and branches.
So they take advantage of sunlight in the canopy without building large bodies.
They store water on spongy tissues.
They have co-evolved with bees and wasps so they pollinate flowers mainly looking for sex partners, so flowers resemble opposite sex or smell like opposite sex.
Flowers are bright colored and they produce large quantities of seeds, like vanilla, with up to a million seeds in each fruit.

Answer 2

Many orchids are epiphytes meaning they grow on tree branches up above, while growing at such high altitudes is an advantage against grazing animals, there is a downside. Orchid seeds are so small they can drift from even the slightest breath of air. But living at such altitudes has it's problems. Water must be collected and stored (which some may use swollen bulb like stems) for future use and being up on branches, it's difficult to get mineral nutrients. Most orchids deal with those difficulties by wrapping a comprehensive system of roots around the branch it sits on. They then intercept rainwater that carries a slight amount of nourishing dust. Other orchids engage in parasitism stealing carbohydrates from mycorrhizal fungi.

Orchids In The Tropical Rainforest

Answer 4

orchids are epiphytes which grow on the branches of other tall plants for sunlight in evergreen forests.
they have short brown unbranched clilnging roots which fix them on the bramch. they have long branched velamen roots which are hygroscopic and absorb moisture from the atmosphere.
root hairs are absent in them.
it has multiple epidermal layers to protect the plant from dessication. orchidaceae is the most advanced family in angiosperms. it shows xerophytic adaptations to come over these water shortage conditions.

Answer 5

Most species grow on the branches of trees. Epiphytes are plants that live on the surface of other plants, especially the trunk and branches. They grow on trees to take advantage of the sunlight in the canopy. Most are orchids, bromeliads, ferns, and Philodendron relatives.
