Cell Organelles and Cell Transport Flashcards
What is the function of the cell membrane?
Regulates what goes in and out of the cell
What are the 4 types of passive transport?
Simple diffusion, osmosis, filtration, and facilitated diffusion
When a cell is in a hypotonic state, the cell…?
Has low osmotic pressure (a little bit of water inside of the cell), cell increases in size, and water moves into the cell
What is endoytosis?
Large partices enter a cell are conveyed in a cesicle that froms from a section of the cell membrane
What are some characteristics of active transport?
It requires ATP and compunds moves from an area of low concentration to an area of high concentration
When a cell is in a hypertonic state, the cell…?
Has high osmotic pressure (a lot of water inside of the cell), it shrinks, and water moves out of the cell
What is the function of the Lysosomes?
Destroys any cellular debris or damaged cells
What is the function of the cytoplasm?
Allows for movement of objects in the cell
What are some characteristics of passive transport?
It requires no ATP and compounds move from and area high concentration to and area of low concentration
What is the function of the Smooth endoplasmic reticulum?
Synthesis lipids and drug breakdown
What is the function of the Nucleus?
Regulates cellular activity
What is the function of the golgi apparatus?
Modifies, transports, and packages different substances, such as proteins
When a cell is in a isotonic state, the cell…?
Has equal osmotic pressure, no net movement of water
What is the function of the mitochondria?
Site of cellular respiration; produces ATP
What is the function of the nucleolus?
Ribosome production
What is the function of the cilia?
Aid in the movement of substances through passage ways
What is the function of the flagellum?
Aids in the movement of the cell
What is the function of the ribosomes?
Site of proteins synthesis
What is Transcytosis?
Combines endocytosis and exocytosis to selectively and rapidly transport a substance or particle from one end of a cell to the other
What is one example of active transport?
Sodium potassium pump
What is the function of the Rough endoplasmic reticulum?
Protein synthesis
What is the function of the microvilli?
Leads to increase of surface area, increasing absorption
What is excocytosis?
Substances made in the cell are packaged into a vesicle, which fuses with the cell membrane releasing it’s contents outside of the cell
