Plant Adaptations

Think What are some challenges plants face on land? Plants overcome these challenges with special adaptations

Adaptation- Cuticle Waxy coating on leaf Prevents water loss Can be very thick or thin What do you think determines whether a plant has a thick or thin cuticle?

Adaptation- Stomata Stoma open and close to control gas exchange and water loss Made up of two guard cells

Adaptation- Vascular Tissue Transports nutrients, water, carbs, and waste around the plant Xylem- moves material up from the roots Phloem- transports material down from the leaves

Adaptation- Seeds Contain embryo, nutrients, and coat Able to survive harsh environments
