mangroves

Question 1

what are the types of mangroves

Answer 1

avicennia, sonneratia, rhizophore, bruguiera

Question 2

which zones are each of the types of mangroves in

Answer 2

coastal zone - avicennia, sonneratia
middle zone - rhizophora
inland zone - bruguiera

Question 3

properties of avicennia
→ zone
→ root
→ leaves
→ fruits
→ how does it tackle problem of salt
→ how does it tackle problem of oxygen
→ how does it tackle problem of reproduction

Answer 3

→ coastal zone
→ pencil-like roots (pneumatophores) that grow up to 30cm
→ salt glands within leaves
→ buoyant fruit that float on water before taking root at a coastal area
→ salt secretors
→ numerous lenticels that allow for gas exchange above the surface of the water
→ buoyant fruit

Question 4

properties of sonneratia
→ zone
→ root
→ how does it tackle problem of salt
→ how does it tackle problem of oxygen

Answer 4

→ coastal zone
→ conical-shaped pneumatophores that grow up to 60cm, uses ultrafiltration to remove salt
→ ultrafiltration
→ numerous lenticels that allow for gas exchange above the surface of the water

Question 5

properties of rhizophora
→ zone
→ root
→ fruits
→ how does it tackle problem of salt
→ how does it tackle problem of oxygen
→ how does it tackle problem of reproduction

Answer 5

→ middle zone
→ prop roots/stilt roots for extra support in air absorption and and anchoring, ultrafiltration to remove salt
→ sharp end of the fruit anchors firmly in the mud
→ ultrafiltration
→ fruits with sharp ends to anchor

Question 6

properties of bruguiera
→ zone
→ root
→ leaves
→ fruits
→ how does it tackle problem of salt
→ how does it tackle problem of oxygen
→ how does it tackle problem of reproduction

Answer 6

→ inland zone
→ knee-like roots for aeration
