What is the prokaryote?
A simple cell containing no nucleus
What is a Eukaryote?
A complex cell containing a nucleus
Within the phospholipid bilayer is the head hydrophobic or hydrophilic?
Hydrophilic
Within the phospholipid bilayer is the tail hydrophobic or hydrophillic?
Hydrophilic
What is the cytoplasm?
Substance that surrounds and supports the organelles of the cell
What is the purpose of ribosomes?
Protein synthesis
What is the nucleus?
Control center of eukartyotic cells, contains DNA
What is the endoplasmic reticulmn
Consist of smooth hand rough
What is the purpose of the Rough ER and what does it have that the smooth er dosent?
Contains ribosomes which helps synthesize proteins
What does the smooth er do?
Detoxfies the cell/makes lipids and fats
What is the purpose of the Golgi Apparatus?
Helps process and package proteins
What is the powerhouse of the cell?
Mitochondira
What do chloroplast do?
Synthesize glucose
What do lysosomes do?
Digest excess/worn down cellular components
What is a vacuole?
Fluid filled sacs?
What is the purpose of a vacuole in a plant
Maintain water balance
What is the purpose of a vacuole in a animal?
Help sequester waste products
What occurs duing prophase?
Chromosomes become visible, spindle fibers being to form
What occurs during metaphase?
Chromosomes meet in the cell center
What occurs during anaphase?
Chromatids/Chromosomes are separated and drawn back to opposite ends of the cell by spindle fibers
What occurs during telophase?
New nuclear envelopes are formed around the chromosmoe’s
What is cytokinesis?
Splits the cytoplasm of the cell
What are the three components of DNA?
Phosphate, Deoxyribose, and Nitrogenous base
What diffferent abt RNA?
Uracil
What does MRNA do?
Copies instructions from the DNA and sends them to the ribosome
What does TRNA do?
Brings amino acids to the ribosome
What is RRNA?
Helps form ribosomes where proteins are assembled
What is transcription?
DNA is copied into mRNA within the nucleus
What is translation?
The cell utilizes mRNA to build a protein
