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.

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.
