Question
Answer
Diffusion   Movement of molecules from an area of greater concentration to lesser concentration Example: exchange of O2 and CO2 in body  
🗑
Mitosis   One cell - diploid chromosomes divide into 2 identical cells Essential for growth and tissue repair  
🗑
lysosomes   Digestive Enzymes  
🗑
Order of mitosis in order   Interphase Prophase Metaphase Anaphase Telophase  
🗑
Mitochondria   Powerhouse of cell, main function is ATP, makes it's own DNA  
🗑
Cilia   Sweep things in a particular direction  
🗑
Endocytosis   Transports into cell  
🗑
DNA rungs & pairings   A to T G to C  
🗑
Phagocytosis   Cell Eating Example: WBC's  
🗑
Cytokinesis   Cytoplasm divides - 2 cells  
🗑
Microvilli   Small folds in cell membrane to increase surface area  
🗑
Golgi Apparatus   Carbohydrates, Packaging  
🗑
Mitosis Phase: Prophase   Condensing DNA in chromosomes  
🗑
DNA triplet is A-T-C what is the corresponding mRNA triplet?   DNA - A,T,C mRNA - U,A,G  
🗑
Centrioles   used in cell division  
🗑
Pinocytosis   Cell Drinking  
🗑
Meosis   Haploid number of cells - forms egg and sperm cells  
🗑
When a hypertonic fluid is administered, how is the solute distributed intally?   pulls H2O from cells & other tissues  
🗑
What are two solutes?   Na, K  
🗑
Hypertonic Solution   concentration is higher than in cells, cells may die  
🗑
When a hypertonic fluid is administered what could happen to the cells in the body?   cells may shrivel & die  
🗑
When a hypertonic fluid is administered, where does the water move to & from?   capillaries take from tissues and other cells  
🗑
Isotonic Solution   Concentration is equal to the cells, no fluid movement, no damage to cells  
🗑
Hypotonic Solution   Concentration less than cells, cells may burst  
🗑
Mitosis Phase: Interphase   DNA replication, growth phase, doubles everything  
🗑
Facilitated Diffusion   Carrier & transporter enzymes move molecules across cell membranes  
🗑
RNA rungs and pairings   A to U T to A C to G  
🗑
Osmosis   movement of H2O through a semi - permeable membrane from a region of greater concentration of H2O to lesser of H2O  
🗑
mRNA   messenger RNA - copy form multiplying  
🗑
Mitosis Phase: Metaphase   Chromosomes line up on equator of cells  
🗑
Haploid   Half - 23 Chromosomes  
🗑
Primary Cilium   Single hair - antenna for cell  
🗑
Mitosis Phase: Telophase   Reforms nuclear membrane  
🗑
tRNA   brings amino acids from cytoplasm to the matching triplet on mRNA  
🗑
Ribosomes   act as protein factories  
🗑
Mitosis Phase: Anaphase   chromosomes split and go to each side of cell  
🗑
Exocytosis   Transport of materials out of the cell in a vesicle  
🗑
Filtration (passive transport)   Movement of H2O & dissolved substances from higher to lower pressure, does not require ATP  
🗑
Active Transport   Requires ATP, movement of molecules from lesser to greater area of concentration  
🗑
Flagella   Have small, thin, tain - such as sperm  
🗑
Codon   The code for a single amino acid consists of 3 bases on the DNA  
🗑
Diploid   46 Chromosomes  
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
