Cilia & Flagella
|
9 + 2 pattern of microtubules
Responsible for the movement of cells
|
Golgi Apparatus
|
Processes, packages, and distributes molecules
|
Vesicle
|
Storage and transport of substances
|
Mitochondrion
|
Responsible for cellular respiration
|
Rough ER & Smooth ER
|
Made of protein and RNA
Responsible for protein synthesis
|
Plasma Membrane
|
Phospholipid bilayer
Selectively allows molecules into and out of a cell
|
Nucleolus
|
Envolved in robosomal formation
|
Centriole
|
Made of 9 + 0 microtubules
Forms basal bodies, which give rise to cilia and flagella
|
Nucleus
|
Central body where genetic information is stored
|
Lysosome
|
Contains digestive enzymes
|
Cytoskeleton
|
Responsible for the shape of the cell and movement of its parts
|
Endoplasmic Reticulum (ER)
|
Synthesis and modifacation of proteins and other substances
|
Why is the plasma membrane said to be selectively permeable?
|
Only small, noncharged molecules can diffuse across the plasma membrane without assistance
|
During diffusion, molecules move from:
|
Higher concentration to lower concentration
|
During facilitated transport, carrier protiens transport molecules from:
|
Higher concentration to lower concentration
