How old is plant life on Earth?
about 1 billion yearsThe earliest complex land plants date back to around 850 Ma, from carbon isotopes in Precambrian rocks, while algae-like multicellular land plants are dated back even to about 1 billion years ago, although evidence suggests that microorganisms formed the earliest terrestrial ecosystems, at least 2.7 Ga.
What was the first thing on land?
The first life on land actually where fungi and then mosses (plants). Fungi came about 542–488.3Ma and made the rocks crack so that early mosses could stay in place with roots. Fungi where first because they need, just like mosses, a wet environment. Plants can’t live on hard rock.

What are the oldest plants on Earth?
Individual plant specimens Methuselah, a Great Basin bristlecone pine (Pinus longaeva) in the White Mountains of California, has been measured by ring count to be 4,852 years old. It is therefore the oldest known living individual non-clonal tree in the world.
Who cut down the oldest tree in the world?

What makes a healthy tree?
The healthiest tree is one that has at least ½ to ⅓ of its total height cloaked in leaves or needles, and is symmetrically-shaped like an umbrella, lollipop, or cone. Deciduous or broadleaf trees tend to grow into an umbrella shape, which is why they are preferred as backyard shade trees.

What 3 things does a tree need to grow?
Like any other plant, trees need sun, water and nutrients for survival. There are three main parts to a tree: the roots, the trunk and the crown (branches and leaves), and each plays a part in helping the tree use the sun, water and nutrients. The roots absorb water and nutrients from the soil.
