(a) plants need nutrients, air, water, light, and a place to grow;
(b) basic parts of plants;
(c) plants can be classified based on a variety of characteristics.
- Plants have different structures that serve different functions in growth, survival, and reproduction.
- The functions of plant parts include the roots which hold plants in place and absorb water, seeds which make new plants, leaves which make food for the plant, and stems which hold the plants upright and transport materials up and down the plant.
- Plants can be categorized by their different characteristics, such as edible/nonedible, flowering/nonflowering, and evergreen/deciduous.
