-
Where can I find the cytoplasm?
inside the cell
-
What is the cytoplasm?
the area within the cell that contains organelles between the plasma membrane and boundary of the nucleus
-
What is cytosol and where it is located?
- a jelly like substance that fills the cell and suspends the organelles.
- Location: between the nucleus and the cell membrane
-
What are memory bound organelles?
organelles enclosed by membranes
-
Whast are the membrane bound organelles in the cytoplasm?
Mitochondria, Endoplasmic Reticulum (Smooth & Rough ER), Golgi Apparatus, Lysosomes, and Peroxisomes
-
What is Mitochondria?
a double bound organelle responsable for producing energy for the cell in the form of ATP (the power house)
-
What is Endoplasmic Reticulum?
a single membrane folded over into different compartments, usually exists close to the nucleus (the assembly site)
-
What are the 2 types of Endoplasmic Reticulum?
Rough ER and Smooth ER
-
What is Smooth ER?
processes fats, toxins, hormones. There are no ribosomes on the surface.
-
What is Rough ER?
site of protein synthesis (creates protein) and has surface bound ribosomes
-
What is the difference between Mitochondria and Endoplasmic Reticulum?
- Mitochondria: a double bound organelle that produces energy
- ER: a single membrane that is the assembly site (protein creater/synthesis)
-
What is the difference between Smooth ER and Rough ER?
- Smooth ER: has no ribosomes on the surface
- Rough ER: has surface bound ribosomes
-
What is Golgi Apparatus?
stacked membranes that take in proteins & enclose them in vesicles (membrane sacks). Golgi is known as the packaging site (getting the proteins ready to be shipped out)
-
What are Lysosomes?
vesicles containing lytic/digestive enzymes that break down cell debri and foreign substances in the cell, like backteria (demolition crew/security). Lysosomes are the protectors, making sure everything is working like it is supposed to.
-
What are Peroxisomes?
vesicles like lysosomes but filled with enzymes that fight free radicals and break down poisons (neutralizers).
-
What are non-membrane bound organelles?
protein structures not surrounded by a membrane that performs a specific function
-
What are the non-membrane bound organelles?
Ribosome, cytoskeleton, Centrioles
-
What are Ribosomes?
protein units that specialize in protein production may be free floating or attach to Rough ER (assembly workers). Ribosomes are the employees.
-
What is Cytoskeleton?
thick and thin protein filaments that form a supportive mesh. Cyte means cell and Skeleton means structure.
-
What organelle is the supportive pilars?
Cytoskeleton
-
What organelle is packeged in a vesicle to be shipped out?
Golgi Apparatus
-
What organelle is the energy generator?
Mitochondria
-
What organelle are the employees (workers=assembly line)?
Ribosomes
-
What organelle is the security?
Lysosome & Peroxisomes
-
What is the boss of the organelles?
DNA
-
What is the wall that holds all the organelles?
plasma membrane
-
What organelle is the boxes office?
nucleus
-
-
What is the storage?
Vacuoles
