2nd qtr: Parts of the cell Flashcards
The semipermeable membrane that surrounds the cell. Controls the substances that enter the cell. Allows discharge of waste materials.
Plasma Membrane
Controls the activity of the cell.
Necleus
Threadlike DNA-containing structures.
Chromosomes
The most distinct structure of the nucleus, is where ribosomes are assembled.
Nucleolus
Jelly-like substance that contains the organelles.
Cytoplasm
Specialized parts of the cell that are analogous to the organs. Each organelle carries out specific functions in the cell.
Organelles
Protein Assembler
Ribosome
An extensive network of membranes.
Its two distinct regions that differ in structure and functions are the rough endoplasmic reticulum (RER) and the smooth endoplasmic reticulum (SER)
Endoplasmic Reticulum
The structure that appears rough because it is studded with ribosomes. Synthesis of the protein and insulin in pancreatic cells.
rough endoplasmic reticulum
A structure whose outer surface lacks ribosomes, thus appearing “smooth”.
It functions in lipid synthesis, carbohydrate metabolism, detoxification of drugs and poison, and also in the storage of irons.
smooth endoplasmic reticulum
Processes, packages, and stores cell secretions.
Golgi apparatus
The powerhouse of the cell. It releases the needed energy for cell activities.
Mitochondrion
Storage for water and substances.
Vacuole
Stores enzymes for the digestion of carbohydrates, fates, and proteins.
Lysosome
Contain the green pigment chlorophyll, which catches light energy. The site of photosynthesis.
Chloroplast
