What organelles are found only in animal cells?
Lysosomes and centrioles
What is the function of lysosomes?
Break down worn out organelles
What is the function of centrioles?
Form spindle during mitosis
What is the function if vacuoles?
Hold water for photosynthesis; create turgor pressure
What is the function if plastids?
Calibrating photosynthetic pigments
What is the function of the cell wall?
Maintain shape and adds protection to cell

What are the 3 major kingdoms represented by algae and marine plants?
Monera(blue green algae)
Protista(green, red, golden brown)
Plantae(sea grass, salt marsh, mangroves)
The thallus is called a sporophyte which produces spores that are diploid and have the same number of chromosomes as parent cell
Asexual
The thallus is called a gametophyte which produces gametes, which are sperm and egg which are haploid
Sexual
What are the 3 major challenges faced by algae/ seaweed that grow near shore waters?
Dessication(drying out)
Grazing (being eaten)
Attachment to substrate( to withstand waves)
What 2 major adaptations have seaweed/ macro algae made to survive along rocky shorelines?
Holdfast & air bladder
What is a fibrous filament that attaches kelp plants to Seabeds?

What helps float up stipe and blade if kelp to surface waters?
Air bladder
What are the 5 major uses of algae by humans?
Used to prepare foods Used in medicine Used in manufacturing goods such as paint Used in making paper products Used in bacterial growth studies
What 4 areas are necessary for the formation of salt marshes
Distinctive tidal fluctuation
Low impact wave areas
Estuary areas
Salinity kept within tolerance level
List the reasons salt marshes are important to animals found in estuaries?
They provide nursery areas, food, and shelter
What are the 3 types of mangroves?
Rhizophoria mangle-water edge
Avicennia Germinas-mid range

Mangroves are what kind of plants
Emergent
What are the 3 major reasons got the decline in sea grass?
Dredge and fill operations
Degraded water quality
Runoff of pollutants and sediments
What are the 5 ways mangroves aid in health of coastal life?
Protect nurseries Provide food Provide shelter Provide nesting sites Provide attachment surfaces
What 3 benefits do mangroves provide to humans?
