6.5 - Importance of Seeds for Survival

Importance of Seeds for Plant Survival

Features that Increase Reproductive Success

• Seeds are used to replant most angiosperms and maintain the survival of plant species.
• A seed contains an embryo that germinates to form a seedling.
• Endosperm tissue or cotyledons supply nutrients and energy during germination.
• A strong, hard, and water-impermeable testa prevents the seed from spoiling.
• A seed can become dormant, allowing it to be stored for a long time.
• Features such as being light, having spongy tissue, being strong, and not spoiling easily help seeds disperse to other places and avoid competition.
