1.4 - Living Systems and Processes

The student will investigate and understand that plants have basic life needs and functional parts that allow them to survive. Key concepts include

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

  • describe the basic life needs of plants. Bloom's Level:  Understand
  • with guidance, plan and conduct an investigation to determine if plants need sunlight and water to grow. Bloom's Level: Apply/ Understand

b)  structures of plants perform specific functions; and

  • explain  the functions of the root, stem, and leaf. Bloom's Level:  Understand
  • create and interpret a physical model/drawing of a plant, including roots, stems, leaves, and flowers to identify and explain the functions of each plant part. . Bloom's Level:  Understand

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

  • classify plants by the characteristicsBloom's Level:  Analyze

BIG IDEAS

Energy and matter are needed for all organisms to survive.

Plants use the matter and energy to grow and reproduce.

Each type of plant has characteristics that allow it to function in unique and specific ways in a particular place.

These characteristics are used to classify plants.

UNDERSTANDING THE STANDARD

  • Energy and matter are required for all organisms to survive.
  • Plants have basic needs, including nutrients, air, water, light, and a place with sufficient space to grow.
  • Plants have different structures such as stems, roots, leaves, and flowers.
  • These structures 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 characteristics.


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

  • describe the life needs of plants.
  • plan and conduct an investigation to answer the question, "Do plants need sunlight and water to grow?
  • explain the functions of the  root, stem, leaf and flower.
  • create and interpret a model/drawing of a plant, including  roots, stems, leaves, and flowers.
  • classify plants by characteristics.
