1.4 - Plant Needs, Parts and Characteristics

The student will investigate and understand that plants have basic life needs and functional parts and can be classified according to certain characteristics. Key concepts include

a)  plants need nutrients, air, water, light, and a place to grow;

  • conduct simple experiments/investigations related to plant needs by changing one variable (nutrients, air, water, light, or place to grow) at a time. Students do not need to know the term variable. Bloom's Level:  Apply / Analyze

b)  basic parts of plants; and

  • create and interpret a model/drawing of a plant, including seeds, roots, stems, leaves, flowers, and fruits.Bloom's Level:  Create / Analyze
  • identify the functions of the seed, root, stem, and leaf. Bloom's Level:  Understand

c)  plants can be classified based on a variety of characteristics.

  • classify plants by the characteristics of edible/nonedible, flowering/nonflowering, and evergreen/deciduous, using charts. Bloom's Level:  Apply

Adopted: 2010

BIG IDEAS

Plants have basic life needs and can be classified into groups.

UNDERSTANDING THE STANDARD

  • Plants have basic needs, including nutrients, air, water, light, and a place with sufficient space to grow.
  • 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. Students do not need to know the terms nonedible, edible, evergreen, and deciduous. The focus should be on the concept, not the terminology.


ESSENTIALS

Essential Questions:

 How do different amounts of food, air, water, light, and space affect plants?

 Why do plants need their different parts?

 How are plants classified?

In order to meet this standard, it is expected that students will

  • conduct simple experiments/investigations related to plant needs by changing one variable (nutrients, air, water, light, or place to grow) at a time. Students do not need to know the term variable.
  • create and interpret a model/drawing of a plant, including seeds, roots, stems, leaves, flowers, and fruits.
  • identify the functions of the seed, root, stem, and leaf.
  • classify plants by the characteristics of edible/nonedible, flowering/nonflowering, and evergreen/deciduous, using charts.
