Life Cycles

Learning Strand: Life Science (Biology): Life Cycles

Learning Standards: Students will:
  • Identify the structures in plants (leaves, roots, flowers, stem, bark, wood) that are responsible for food production, support, water transport, reproduction, growth, and protection.
  • Recognize that plants and animals go through predictable life cycles that include birth, growth, development, reproduction, and death.
