Transcript of The Galaxy

Spiral Galaxy vs. Animal

a prezi by Tommy Malone
1) All living things are composed of cells
2)Basic building block of life
3)New cells are produced from living things

Cell Theory
The halo is a large ring
surrounding the galaxy.
it is made up of hot gases
and dark matter.
The cell membrane is a thin, flexible barrier around a cell that
regulates what enters and leaves the cell.

The Halo acts as a cell membrane because it regulates what comes in and out of the galaxy (cell).
Nucleus vs. Sun
the nucleus contains nearly all the cell's DNA and with it the coded instructions for making proteins and other important molecules
Cytoplasm vs. Galactic Disk
the cytoplasm is the
material inside the cell
the galactic disk is
the area inside the
halo, made up of the
nucleus, bulge, and
spiral arms
The Galactic Disk acts as the Cytoplasm by providing shape for the galaxy (cell).
the sun is the basis of solar sytems and helps sustains life on planets like earth
The sun acts like a nucleus by influencing the galaxies (cell's) actions due to gravity (DNA).
Nucleolus vs. Core of the Sun
the nucleolus is a small dense
region where assembly of
ribosomes begins
the core of the sun is
the source of the sun's
The Sun's core acts as a nucleolus by making a source of energy (ribosomes) for the Sun and Galaxy.
Corona of the Sun vs. Endoplasmic Reticulum
the rough Endoplasmic Reticulum
produces proteins, while the
smooth endoplasmic reticulum
produces lipids and carbohydrates
the corona of the sun
produces energy in the form of light and heat which helps sustain life in the galaxy
Corona of
the Sun
The Corona of the Sun acts as the Endoplasmic Reticulum by supplying the galaxy (cell) with heat and light, which it needs to survive, like a cell needs proteins, lipids, and carbohydrates.
Spiral Arms vs. Cytoskeleton
the cytoskeleton is a network of protein filaments that helps the cell to maintain its shape. The cytoskeleton is also involved in movement.
spiral arms organize solar
systems in the galaxy
spiral arms
Spiral Arms act as a Cytoskeleton by organizing solar systems in the galaxy as the cytoskeleton organizes the cell and helps it maintain its shape
Vacuoles vs. Nebulae
vacuoles are structures that store materials such as water, salts, proteins, and carbohydrates.
Nebulae act as vacuoles by storing ionized gases (materials) in the galaxy that the cell can use throughout itself.
Lysosomes vs. Black Holes
lysosomes are small organelles filled with enzymes. One function of lysosomes is the digestion, or breakdown, of lipids, carbohydrates, and proteins into small molecules that can be used by the rest of the cell. lysosomes are also involved in breaking down organelles that have outlived their usefulness.
black holes are large, strong gravitational fields made up of dense matter in a small area that have so much mass that they attract everything in their paths
Black Holes act as Lysosomes by dissecting organelles and other parts of the galaxy (cell).
Black Hole
Galactic Magnetic Fields vs. Vesicles
Vesicles function in delivering nutrients and proteins throughout the cell from the Golgi apparatus
Galactic Magnetic Fields are
weak magnetic forces that influence the path of light in the galaxy
Galactic Magnetic Fields act as Vesicles by transporting light (nutrients) throughout the galaxy from the sun.
Nebulae are clouds of dust, hydrogen, helium, and ionized gases
that can form new stars
Golgi Apparatus vs. Globular Clusters
The function of the Golgi apparatus is to modify, sort, and package proteins and other materials from the endoplasmic reticulum for storage in the cell or secretion outside the cell.
Globular Clusters are groups
of stars that surround the center of the galaxy
Globular Clusters act as the Golgi apparatus by storing the light (materials) and sending them out through the magnetic field (vesicles).
Spiral Galaxy vs. Animal Cell
Globular clusters
Sun, Core, Corona
Magnetic Fields
Black Hole
Galactic Disk
Cell Membrane
Diffusion is the process when particles that move tend to move from an area where they are more concentrated to an area where they are less concentrated
Osmosis is the diffusion of water through a selectively permeable membrane

Phospholipids are made up of two parts: the hydrophilic polar head and the hydrophobic nonpolar fatty acid tail of the phospholipid. Cholesterol helps the phospholipid keep its structure.
