Seeds-Living or not

Key Notes :

What Are Seeds?

  • Definition: Seeds are the reproductive structures of plants that can grow into new plants. They contain an embryo, a supply of nutrients, and a protective outer covering.

Are Seeds Living or Non-Living?

  • Seeds Are Living: Seeds are considered living because they have the potential to grow into a new plant, but they may appear inactive when they are not germinating.

Characteristics of Seeds That Show They Are Living

  1. Dormancy:
    • Definition: A state of rest or inactivity in seeds where metabolic processes are slowed down.
    • Example: Seeds can remain dormant for long periods until the right conditions for growth are met, such as water, warmth, and light.
  2. Germination:
    • Definition: The process by which a seed absorbs water, swells, and begins to grow into a new plant.
    • Steps:
      • Absorption: Seed takes in water, which activates the cells inside.
      • Growth: The embryo starts to grow, breaking through the seed coat.
      • Development: Roots and shoots develop, leading to the formation of a new plant.
  3. Cellular Activity:
    • Definition: Seeds contain living cells that are capable of resuming activity when conditions are right.
    • Example: Metabolic processes in the seed resume once it starts to germinate.
  4. Nutrient Storage:
    • Definition: Seeds contain stored nutrients that support the growth of the embryo during germination.
    • Example: The endosperm or cotyledons in the seed provide energy and nourishment for the developing plant.
  5. Adaptation for Survival:
    • Definition: Seeds have adaptations to protect themselves and ensure survival until conditions are favorable for growth.
    • Example: The seed coat protects the embryo from damage and desiccation.

How Seeds Differ from Non-Living Things

  • Potential for Growth: Unlike non-living things, seeds have the potential to grow into a new plant when conditions are right.
  • Metabolic Processes: Seeds, though dormant, have living cells that can become active.

Importance of Seeds

  • Reproduction: Seeds are essential for the reproduction of plants and the continuation of plant species.
  • Ecosystems: Seeds play a crucial role in ecosystems by allowing plants to spread and colonize new areas.
  • Food Source: Many seeds are important food sources for humans and animals.
