---|---|---|---|---|---|
anaphase | a phase of mitosis and meiosis in which the chromosomes separate
🗑
|
||||
asexual reproduction | reproduction that does not involve the union of gametes and in which a single parent produces offspring that are genetically identical to the parent
🗑
|
||||
autosome | any chromosome that is not a sex chromosome
🗑
|
||||
chromosomes | in a eukaryotic cell, one of the structures in the nucleus that are made up of DNA and protein; in a prokaryotic cell, the main ring of DNA
🗑
|
||||
cytokinesis | the division of the cytoplasm of a cell; cytokinesis follows the division of the cell's nucleus by mitosis or meiosis
🗑
|
||||
interphase | the period of the cell cycle during which activities such as cell growth and protein synthesis occur without visible signs of cell division
🗑
|
||||
metaphase | one of the stages of mitosis and meiosis, during which all of the chromosomes move to the cell's equator
🗑
|
||||
mitosis | in eukaryotic cells, a process of cell division that forms two new nuclei, each of which has the same number of chromosomes
🗑
|
||||
prophase | the first stage of mitosis and meiosis in cell division; characterized by the condensation of the chromosomes
🗑
|
||||
sex chromosome | one of the pair of chromosomes that determine the sex of an individual
🗑
|
||||
telophase | the final stage of mitosis or meiosis, during which a nuclear membrane forms around each set of new chromosomes
🗑
|
||||
plant | multicellular eukaryote that produces its own food through photosynthesis
🗑
|
||||
vascular system | collection of specialized tissues in some plants that transports mineral nutrients up from the roots and brings sugars down from the leaves
🗑
|
||||
pollination | the transfer of pollen from the male reproductive structures (the anthers) to the tip of the female reproductive strcture (the pistil) of a flower in angiosperms or to the ovule in gymnosperms
🗑
|
||||
gymnosperm | a woody, vascular seed plant whose seeds are not enclosed by an ovary or fruit
🗑
|
||||
angiosperm | a flowering plant that produces seeds within a fruit
🗑
|
||||
cell cycle | pattern of growth, DNA replication, and cell division that occurs in a eukaryotic cell
🗑
|
||||
mitosis | in eukaryotic cells, a process of cell division that forms two new nuclei, each of which has the same number of chromosomes
🗑
|
||||
homologous chromosome | chromosomes that have the same length, appearance, and copies of genes, although the alleles may differ
🗑

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.
