Plants are many celled organisms that have cell walls and make their own food using the sun’s energy (photosynthesis). Most plants live on land, and the resources they need are separated by the air and soil. Sunlight, oxygen and carbon dioxide are in the air, and minerals and water are in the soil.
-Plants have roots that access water and nutrients in the soil, and leaves that collect light and gases from the air.
-The roots and leaves are connected by vascular tissue.
Classification of Plants
Plants reproduce with sex cells and with spores. Their life cycle has two stages:
- Sporophyte: makes spores
- Gametophyte: makes sex cells (gametes)

Winter Trees
There are two ways to identify trees in the winter:
-Twigs
-Needles/Leaves
Evergreen Trees (gymnosperms) are woody plants that produce seeds inside of cones.
-They are also known as conifers.
-They are adapted to living in much dryer conditions; their needle-like leaves lose little water.
-They also retain their leaves throughout the year; instead they gradually shed their needles throughout the year (instead of losing them all in the fall).
Directions for using the tree finder guides:
- Select a typical leaf from the tree you wish to identify. Avoid freaks.
- Start at the top of page 5.
- Proceed step by step, considering both choices under each symbol.
- When you have made your final choice, arriving at the name of the leaf, compare your leaf with the illustration and check the other features shown.
- Always check to see if the tree is in our region
- There are more directions on pp 2-4 in the actual guide
