DESCRIBE MARINE PLANT PHYSICAL CHARACTERISTICS

INSTRUCTIONAL OBJECTIVES  1. Identify adaptations of marine plants.  2. Describe the habitats of marine plants.  3. List benefits of marine plants to the oceans and marine life.

PHYSICAL CHARACTERISTICS  Roots  Stems  Leaves  Flowers  Seeds  Describe some benefits to the marine environment and marine organisms by marine plants?

BENEFITS  Oxygen  Food  Habitat  Stabilize land/beach with roots  Lessen storm impact/protect land

DESCRIBE SOME COMMON FEATURES AMONG MARINE PLANTS?  They have leaves for photosynthesis, roots for absorbing water/ anchor and stems for transport. True plants have stems, roots and leaves. They are called vascular plants. MARINE PLANTS have many ADAPTATIONS allowing them to survive in ocean and coastal environments. Vascular plants are classified in kingdom plantae and phylum tracheophyta.  PLEASE GUESS THE AIM????????

AIM: HOW ARE MARINE PLANTS ADAPTED TO THEIR ENVIRONMENT?

How can we describe the structure/function relationship in marine plants? STRUCTURE  1. leaf  2. stem  3. root  4. flower  5. xylem  6. phloem  7. stamen/anther  8. pistil/style/egg MARINE PLANT STRUCTUREMARINE PLANT FUNCTION LEAF ROOT STEM FLOWER XYLEM PHLOEM STAMEN/ANTHER/POLLEN PISTIL/STYLE/EGG

MARINE PLANTS

MARINE PLANT CHARACTERISTICS AND HABITAT ACTIVITY  1. Each group will be assigned a marine plant and given a worksheet.  2. Research the plants scientific name  3. Research the plants identifiable characteristics  4. Research the plants habitat  5. Cut out and tape or staple a picture of the plant in your notes

REPRODUCTION/NUTRITION  How do marine plants reproduce?  How do marine plants get nutrition?

REPRODUCTION/NUTRITION  Plants reproduce asexually with spores or cuttings  Wind, animals, water, insects and birds help disperse pollen and seeds sexually  photosynthesis

MARINE PLANT SUMMARY  Marine plants are vascular and possess a variety of adaptations in their roots, stems and leaves. These adaptations allow them to live in diverse coastal habitats from the subtidal to the supratidal zones. They provide oxygen, shelter and food for marine life.
