Question | Answer |
Ribosomes (Both) | A small grain like sturture in the cytoplasm of a cell where proteins are made. |
Cell membrane (Both) | A cell sturture that controls which substances can enter or leave the cell. |
Endoplasmic reticulm (Both) | A cell sturture that forms a maze of passageways in which proteins and other material are carried out from one part of the cell to another. |
Cell wall | A rigid layer of nonliving material that surrounds the cells of planst and some other organsim. |
Nucleus | A cell sturture that contains nucleic acid the chemicals insturtions are what direct all the cells activities |
Mitochondria | Rod shaped cell sturtures that produce most energy needed to carry out the celles function. |
Golgi Bodies | A sturture in a cell that recessive proteins and other newly formed material from the endoplasmic reticulm packages them and distributes them to other parts of the cell. |
Chloroplasts | A cell sturture that captures energy from the sun and uses it to produce food. |
Vacuoles | A water filled sac inside a cell that acts as a storage area. |
Lysosomes | A small round cell sturture that contains chemicals that break down large food particles into smaller ones. |
Gene | A segment of DNA of a chromosome that codes a specifc trait. |
Chromosome | A double rod of condensed chromatin contains DNA that will carry gentic imformation. |
Trait | A characteristic that an organism can pass onto it's offspring through genes. |
Allele | Different form of gene |
Donimant Allele | An allele who's trait always shows up in the organsim when the allele is present. |
Recessive Allele | An allele that is masked when a dominant allele is present. |
Homozygous | Having two identical alleles for a trait. |
Heterozygus | Having two different alleles for a trait. |
Genotype | An organsims genetic make up or allele combinations |
Phenotype | An oransims physical apperance or visiable trait. |
Robert Hooke | One of the first people to observe cells. |
Leeuwenhoke | Made the first simple mircoscope. |
Schiedian | Concluded that all plants are made up of cells. |
Schwann | Concluded that all animals are made up of cells. |
Rudolf | Proposed that all cells come from other cells. |
Prophase | Condenses to form chromoses |
Metaphase | Chromosomes attach to spindle fibers |
Ananphase | Two chromatids sperate |
Cytokienes | New nuclear membranes form. |
The double-stranded chromosomes move to the center of the cell and sperate. | Meiosis 1 |
The chromosomes pairs sperate. | Meiosis 2 |
Four cells form with half the number of chromosomes as the parental cells. | End meiosis |
The chromosomes are copied. | Beginning of meiosis |
The centomeres divide and sperate. | Meiosis 2 |
