Segments in this Video

The World of Plants: Introduction (01:07)


All animals rely on plants for survival. Learn about photosynthesis.

The First Plants (02:14)

The first organisms appeared in seas; single celled algae developed photosynthesis millions of years ago. Learn about red, brown, and green algae.

Crossing to Land (03:35)

Plants had to develop systems of nutrient and sexual cell transport to live on land. Moss still requires water to reproduce while ferns have a vascular system and supportive tissue. Learn about their reproduction process.

Seeds (02:56)

Seed bearing plants are spermatophytes; learn about conifer reproduction. Flowering plants rely on insects for fertilization and produce fruit whose seeds are distributed by animals. Grasses depend on the wind for pollination.

The World of Plants: Summary (02:17)

Plants use photosynthesis to produce organic matter that feeds other organisms. Plants first appeared in oceans, evolved to algae, and moved to land. Learn about reproduction in moss, ferns, and seed plants.
