Who Said Plants Were Boring?Presentation Transcript
Who said plants were boring??
Think of a place without plants. The only such places on Earth are the arctic wastelands, really arid deserts, and the deep ocean. Everywhere else, from the tundra to the rainforest to the desert, is populated by plants.
There are more than 250000 species of plants in the world
Because they cannot move, plants must be responsive to the environment and adapt to the seasons
Plants must survive inhospitable dry seasons or winters as seeds or bulbs In the case of some trees in a "bare-bones" leafless state.
Because they cannot move, plants are prone to being eaten. They have a unique mode of development. This involves plants growing by meristems at their tips.
All plant cells are totipotent. An entire new plant can form from a single plant cell
Plants use the simplest materials around to generate size – water, light and CO 2 . They literally make themselves out of thin air!
Plants don’t have bones for support. They rely on water!
