Transcript of Great Barrier Reef

Great Barrier Reef
Cell Theory
1. All living things are composed of cells
2. New cells are produced from existing cells
3. Cells are the basic unit of structure and function in living things
Cytoskeleton
Protein filaments that help a cell retain its shape, and also help the cell move
Cell Wall
Found only in plant cells, the cell wall helps the cell retain its shape, and helps hold the organelles in
Ribosomes
Organelles that produce proteins to be used inside the cell
Nucleus
The coral makes up the structure of the reef
The "cell wall" of the coral reef is the surface of the water, its outermost boundary
Cytoplasm
The water that surrounds the Great Barrier Reef could be likened to the cytoplasm in a plant cell because it fills the empty space above and around the reef
Endoplasmic Reticulum
Present in all cells
There are two types of endoplasmic reticulum
Rough Endoplasmic Reticulum
Has ribosomes on its surface
Synthesizes and secretes proteins
Smooth Endoplasmic Reticulum
Has no ribosomes on its surface
Synthesizes lipids
A Rough Endoplasmic Reticulum would be sea anemones which some fish (which I previously compared to ribosomes) live
Cell Membrane
The cell membrane works as a 'gatekeeper', monitoring what goes in and out of the cell.
The cell membrane is composed of phospholipids, arranged in a bilayer, with hydrophobic tails facing inwards and hydrophilic heads outwards
The cell membrane of the Great Barrier Reef is the bare ocean floor surrounding the reef
Chloroplast
The sunlight that filters through the water to the reef gives the reef energy and the ability to grow
Contains chlorophyll, a green pigment responsible for the absorption of light to provide energy for photosynthesis
The organelle inside a plant cell in which photosynthesis takes place
The nucleus contains DNA responsible for growth and reproduction
Fish that inhabit the coral reef could be compared to the ribosomes in a cell
Vacuole
Lyosome
The large central vacuole in a plant cell stores materials and helps support the cell structure
The vacuole of a coral reef could be a shipwreck which provides a home for fish and a structure on which coral can grow
The lyosome is filled with enzymes and breaks down lipids, carbohydrates, and proteins into molecules which the cell can use. It also breaks down old organelles and other debris inside the cell
The lyosome of the Great Barrier Reef could be cleaner fish, or sharks, which get rid of unwanted materials within the reef
Brain Coral. (This is my lame attempt to get humor points)
The Smooth Endoplasmic Reticulum could be compared to a sea slug, which, like the smooth endoplasmic reticulum, excretes materials
The cytoplasm is a jelly-like substance that fills the open spaces in a cell and helps hold organelles in place
Osmosis-
process by which materials dissolved in water pass through a semipermeable membrane
Diffusion-
the transport of a solvent from an area of high concentration to an area of lower concentration
Phospholipid-
a phosphorus containing lipid
