test 1 grd 10
cells, organelles, dna
| Question | Answer |
|---|---|
| what are the three cell theories? BAP | cells are the basic organizational units of life all organisms are made up of one or more cells all cells are made from pre existing cells |
| what is the structural units and functional units of life? | structural units form the structure of the organizm ( cell membrane, cell wall ) funtional units carry out tasks such as nutrition, excretion, respiration. |
| what is the cytoplasm and cytosol? | gel like substance that holds the organelles. the cytosol the the gel by itself. |
| nucleus | the nucleus protects the DNA and controls all cell activities |
| nucleolus | makes ribosomes |
| cell membrane | controls what gets in and out of the cell ( made up of phospholipid bilayer ) |
| endoplasmic reticulum | transport proteins from nucleus |
| mitochondrion ( dria ) | the powerhouse of the cell, provides energy (ATP ) to the cell through cellular respiration |
| golgi body | sorts and packages proteins and other materials for transport out cell |
| ribosomes | makes protein |
| vacuole | stores water and nutrients |
| lysosome | cleans up cell |
| chromatin | uncondenced chromosome that contains the instruction for the characteristics the cell will have. ( turns into chromosomes before cell reproduction ) |
| vesicle | stores materials and transports them throughout and out the cell |
| cell wall | provides structural support to the cell |
| chloroplast | stores energy from the sun to make glucose ( photosynthesis ) |
| phospholipid bi layer | makes up the cell membrane hydrophilic head, hydrophobic tail allows cell to be selectively permeable |
| what do plant cells have that animal cells don't? | larger vacuoles - because they can't move around to go find water cell wall - so they can grow up taller to the suns light chloroplast - stores sunlight to make food from the plant with carbon dioxide |
| what are the 4 nitrogen base pairs of a DNA | Adenine - Thymine Guanine - Cytosine |
| why do the nitrogen base pairs pair the way they do? | due to hydrogen bonds, specifically A & T ( 2) , C & G ( 3 ) can only pair with each other, this way you can always tell the other half of the code is with just the first half |
| how does the DNA act as a code | the DNA acts as a code because the nitrogen base pairs are always the same and never changing so they can act as a computer code and be placed in sequences like codes. |
| nucleotide | a nucleotide is a singular nitrogen base, sugar ( deoxyribose ), and phosphate |
| transgenic organisms | ( human made ) an organism that has had its genetic code altered with gens from another organism |
| mutations | ( natural ) a change in the DNA of an organism |
| mutagens | substance/factor that can cause DNA mutation ( x rays, uv rays ) |
| types of genetic screening methods for genetic disorder | PKU - test for excessive or too little protein Karyotype - micrograph of chromosome to look for things like down syndrome |
| what are proteins? | proteins are important molecules made by a small part of the gene that carry out different jobs in the body i.e. transfer signals between body parts, and speed up bodily chemical reactions ( catalyst ) |
| relationship between DNA, genes, and proteins | DNA makes genes genes make proteins the job of the protein is decided by the DNA |
| what is a karyotype? and use | an individuals complete set of chromosomes. can be used to look for abnormalities or disorders like down syndrome, Huntington disease |
| DNA | deoxyribonucleic acid deoxyribose - sugar nucleic - in the nucleus acid - the chemicals |
| centrioles | responsible for cell reproduction |
