Plant Growth and Life Cycle Concepts

The video tutorial covers the life cycle of plants, starting with vocabulary such as germinate, mature, sapling, and seedlings. It reviews plant parts like roots, stem, leaves, and their functions, including photosynthesis. The life cycle stages from seed to mature plant are explained, with examples of sunflower and oak tree life cycles. The process of germination, growth, and decay is detailed, emphasizing the role of seeds and nutrients in the soil.

What does the term 'germinate' mean in the context of plant growth?

• To fully develop into an adult plant

• To start to grow from a seed

• To become a young tree

• Water, light, and nutrients

What is a seedling?

• A decayed plant

• 50 years

• 100 years

• 20 years

What role do squirrels play in the life cycle of an oak tree?

• They eat the acorns, preventing germination

• They plant acorns by forgetting where they buried them

• They protect the acorns from predators

• They water the acorns

What happens to a sunflower when it dies?

• It grows into a tree

• It becomes a sapling

• It turns into a seedling

• Decay

• Mature plant

• Seedling

What is the significance of decayed plants in the soil?

• They provide nutrients for new seeds to germinate

• They prevent new seeds from germinating

• They attract pests

• They block sunlight
