Why do orchids have air roots and how do they help the plant survive in its natural environment?

Orchids have air roots to absorb moisture and nutrients from the air. These roots help the plant survive in its natural environment by allowing it to gather resources even when the soil is dry or lacking in nutrients. This adaptation helps orchids thrive in their often epiphytic or semi-epiphytic habitats, where they grow on trees or rocks rather than in the ground.

What do epiphytic and parasitic plants grow on?

Epiphytic plants are plants which attach to other living plants. They do not have roots in soil, but may use roots to help secure them to their host, and for this reason are sometimes known as "air plants". Epiphytes use photosynthesis for energy and generally obtain any moisture they need from the air or from humidity coming through rain and fog, on the surface of their hosts. Sometimes they develop features such as cups and scales to collect the moisture.


What kind of root tends to grow in a dense network near the surface of the earth so it can breath out and collect water?

Aerial roots, such as those found in mangroves and epiphytic plants, grow in a dense network near the surface of the earth to absorb oxygen and gather water. These roots are specialized for supporting the plant and facilitating gas exchange in environments with limited access to soil nutrients.


How many kinds of trees are there that grow from roots?

All trees grow up by and from the roots.Specifically, it is by the roots that trees, shrubs and herbaceous plants take in necessary nutrients. Not all plants have to be anchored in soil. Epiphytic orchids whose roots dangle from tree branches high up in the air may be offered as examples of herbaceous plants that can live without soil. But all trees must have roots growing in soil to survive.
