Question
Answer
cytokinesis   the division of the cytoplasm of a cell  
🗑
cell   in biology the smallest unti that can perform all life processes, they are covered by a membrane and have DNA and cytoplasm  
🗑
procaryote   a single-celled organism that does not have a nucleus or membrane-bound organelles; examples are archaea and bacteria  
🗑
cell membrane   a phospholipid layer that covers a cell’s surface and acts as a barrier between the inside of a cell and the cell’s environment  
🗑
eukaryote   an organism made up of cells that have a nucleus enclosed by a membrane; eukaryotes include protists, animals, plants, and fungi but not archaea or bacteria  
🗑
organelle   one of the small bodies in a cell’s cytoplasm that are specialized to perform a specific function  
🗑
lysosome   a cell organelle that contains digestive enzymes  
🗑
endoplasmic reticulum   a system of membranes that is found in a cell's cytoplasm and that assists in the production, processing, and transport of proteins and in the production of lipids  
🗑
cell wall   a rigid structure that surrounds the cell membrane and provides support to the cell  
🗑
ribosome   a cell organelle composed of RNA and protein; the site of protein synthesis  
🗑
vesicle   a small cavity or sac that contains materials in a eukaryotic cell; forms when part of the cell membrane surrounds the materials to be taken into the cell or transported within the cell  
🗑
mitochondrion   in eukaryotic cells, the cell organelle that is surrounded by two membranes and that is the site of cellular respiration, which produces ATP  
🗑
nucleus   in a eukaryotic cell, a membrane-bound organelle that contains the cell’s DNA and that has a role in processes such as growth, metabolism, and reproduction  
🗑
cell cycle   the life cycle of a cell  
🗑
golgi complex   a cell organelle that helps make and package materials to be transported out of the cell  
🗑
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  
🗑
mitosis   in eukaryotic cells, a process of cell division that forms two new nuclei, each of which has the same number of 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.
