Transcript Period 1

Period 1
ER
• Is the site where liquid components of the cell
membrane are assembled along with proteins
and other materials that exported from the
cell.
• Network of tunnels throughout the cell.
• Two kinds = Smooth & Rough (= bumpy
because it has ribosomes attached)
Golgi Apparatus
• To modify , sort, and package proteins and
other materials from the endoplasmic
reticulum for storage in the cell or secretion
outside the cell.
• Located near the cell wall.
• May also be called “Golgi Body.”
Nucleus
• Contains nearly all the cells DNA.
• The coded instructions for making proteins
and other important molecules
• Molecules move through the nuclear pores to
and from the rest of the cell
• The nucleolus is where the assembly of
ribosomes begins
• Located anywhere in the cell.
Mitochondria
• Mitochondria are organelles that convert the
chemical energy stored in food into
compounds that are more convenient for the
cell to use.
• Its found in the eukaryotic cells, and plant
cells. And is enclosed by two membrane.
Chloroplast
• Chloroplast collects energy form sunlight and
turns it into chemical energy called
photosynthesis
• The chloroplast is located in plants and some
insects.
• Located by two membranes and inside the
organelle are stacks of membranes which
contains the green pigment chlorophyll
Ribosomes
• Ribosomes make protein.
• Ribosomes are small particles of RNA and
protein found throughout the cytoplasm and
also attached to rough ER.
Cytoskeleton
• The Cytoskeleton is a network of protein
filaments that helps the cell maintain its
shape. Also involved in movement.
• Microfilaments and microtubles make up the
cytoskeleton.
• Located near the nucleus.
Lysosomes
• The clean-up crew
• Small organelles filled with enzymes
• Breaks down proteins, carbs, and lipids into
molecules for the cell to use
• Can cause serious human illness
Cilia
• Cilia is used for both feeding and movement
• Cilia is located outside of the cell, they
surround the cell completely and are short
• Examples: Found in unicellular organisms that
live in both fresh and salt water (animal)
Flagella
• Used for movement
• Whip-like structure
• Located outside cell

Supports cell
Found in some single celled organisms
Helps with homeostasis
Long and located centrally
Always in plants & sometimes animals
Period 3
ER
• ER is shorter for Endoplasmic Reticulum.
• ER is included in the, synthesis of proteins is
called rough ER (has ribosomes & looks
rough). Smoother ER contains collections of
enzymes that perform special tasks.
Movement of materials through cell.
• Membrane; throughout cell
Golgi Apparatus
• The function of the Golgi apparatus is to
modify, sort and package protein and other
materials from the endoplasmic reticulum for
storage in the cells or secretion outside the
cell.
• Wave appearance in the near the cell
membrane (edge) of both animal and plant
cells.
Nucleus
•
•
•
•
Contains the cells DNA
Located in the middle of the cell
Looks like a bouncy ball
Chromatin (the granular material in the
nucleus) surrounds the nucleolus
Mitochondria
• Mitochondria are organelles that convert the
chemical energy stored in food into
compounds that are more convenient for the
cells to use
• Found in the outer edge of the cell
• Almost looks like a kidney
Chloroplast
• Mostly found in plant cells
• Capture the energy from sun light and convert
it into chemical energy (Photosynthesis)
• Surrounded by Membranes
Ribosomes
• Ribosomes make protein.
• Ribosomes are small particles of RNA and
protein found throughout the cytoplasm and
also attached to rough ER.
Cytoskeleton
• The Cytoskeleton is a network of protein
filaments that helps the cell maintain its
shape. Also involved in movement.
• Microfilaments and microtubles make up the
cytoskeleton.
• Located near the nucleus.
Lysosomes
•
•
•
•
•
Small organelles filled with enzymes
They digest & break down lipids, carbs, etc.
Removes junk that clutters cell
Medium sized, like mitochondria
If it fails, cell dies.
Cilia
• Short hairlike projection similar to a flagellum.
• Produces movement in cells, found on the
outside of the cell wall.
• Propels cells rapidly through the water
• Only in animal cells
Flagella
• Flagella are long whiplike projections that
allow cell to move through their aquatic
environments
• It looks like a long tail on the backside of the
cell
• Only found in animal cells
Vacuole
• They store materials such as water, salt,
proteins, and carbohydrates
• They’re found in both plants and animals
• Has a sack-like structure
• Found near the middle of the cell
• One of the biggest structures in the cell
Period 5
ER
• The internal membrane in the Eukaryotic cells
• Endoplasmic Reticulum
• Lipid component assemble, proteins and other
materials exported
• Wrapped around the nucleus
• Two varieties:
– Smooth – no ribosomes
– Rough – has ribosomes embedded
Golgi Apparatus
• Modifies & sorts packaged proteins from the
ER for storage
• Looks like a stack of closely opposed
membranes
• Puts finishing touch on proteins
Nucleus
• Contains nearly all the cell’s DNA and with it
the coded instructions for making proteins
and other important molecules
• Surrounded by nuclear envelope
Mitochondria
