Cells Flashcards
What are the typical functions of an animal cell?
Eliminate waste, maintain a distinct internal and external environment, grow, and take in nutrients
What are the common structures found in an animal cell?
Nucleus, cell membrane, and cytoplasm
True or False? The cytosol is the same as the cytoplasm.
False
What is typically found in a cell membrane?
Proteins, cholesterol, phospholipids, and carbohydrates
What is the function of carbohydrates?
Identification tags
What is the function of phospholipids?
Makes up the majority of cell membrane structure
What is the function of a protein?
Enzymes
What requires ATP?
Active transport, exocytosis, and endocytosis
In which direction does the solute move during diffusion?
Down its concentration gradient
In which direction does the solute move during active transport?
Up it’s concentration gradient
What does facilitated diffusion require?
Concentration gradient and membrane protein
What is the function of the smooth endoplasmic reticulum?
Produces lipids
What is the function of the mitochondria?
Synthesize ATP
What is the function of the nucleus?
Contains DNA
What is the function of the ribosome?
Synthesize proteins
What is the function of a peroxisome?
Chemical detoxification
What is the function of the rough endoplasmic reticulum?
Process, modify, and package proteins
What is the function of the cytoskeleton?
Provides structure to the cell
What is the function of a lysosome?
Contains enzymes for digesting unwanted cellular components
What is the function of the microvilli?
Increases cell surface area for absorption or secretion
What is the function of the cilia?
Moves substances past a cell
What is the function is the flagella?
Moves a cell
What is are tight junctions?
Connects cell tightly, not allowing substances to pass in between cells
What are desmorones?
A strong connection linking cells at one point
What are gap junctions?
Creates a pore between two cells allowing a signal to pass from one cell to the other
True or False? Mitosis results in two genetically identical cells
True
What is true of meiosis?
Meiosis results in four cells with half the genetic material

Ribosomes
What is the product of transcription in protein synthesis?
mRNA
What is the product of translation in protein synthesis?
Protein
