---|---|---|---|---|---|
Cell | Basic unit of all forms of life.
🗑
|
||||
Cell Theory | Fundamental concept of biology that states all living things are composed of cells; that cells are the basic units of structure and function in living things; and that new cells are produced from existing cell.
🗑
|
||||
Cell Membrane | Thin, flexible barrier that surrounds all cells; regulates what enters and leaves the cell.
🗑
|
||||
Nucleus | The center of an atom, which contains the protons and neutrons; in cells, structure that contains the cell's genetic material in the form of DNA.
🗑
|
||||
Eukaryote | Organism whose cells contain a nucleus.
🗑
|
||||
Prokaryote | Unicellular organism that lacks a nucleus.
🗑
|
||||
Cytoplasm | In eukaryotic cells, all cellular contents outside the nucleus, in prokaryotic cells, all of the cell's contents.
🗑
|
||||
Organelle | Specialized structure that performs important cellular functions within a cell.
🗑
|
||||
Vacuole | Cell organelle that stores materials such as water, salts, proteins, and carbohydrates.
🗑
|
||||
Lysosome | Cell organism that breaks down lipids, carbohydrates, and proteins into smaller molecules that can be used by the rest of the cell.
🗑
|
||||
Cytoskeleton | Network of protein filaments in a eukaryotic cell that gives the cell its shape and internal organization and is involved in movement.
🗑
|
||||
Centriole | Structure in an animal cell that helps to organize cell division.
🗑
|
||||
Ribosome | Cell organelle consisting of RNA and protein found throughout the cytoplasm in a cell, the site of protein synthesis.
🗑
|
||||
Endoplasmic Reticulum (ER) | Internal membrane system found in eukaryotic cells; place where lipid components of the cell membrane are assembled.
🗑
|
||||
Golgi Apparatus | Organelle in cells that modifies, sorts, and packages proteins and other materials from the endoplasmic reticulum for storage in the cell or release outside the cell.
🗑
|
||||
Chloroplast | Organelle found in cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy.
🗑
|
||||
Cell Wall | Strong, supporting layer around the cell membrane in some cells.
🗑
|
||||
Selectively Permeable | Property of biological membranes that allows some substances to pass across it while others cannot; also called semipermeable membrane.
🗑
|
||||
Mitochondria | Cell organelle that converts the chemical energy stored in food into compounds that are more convenient for the cell to use.
🗑

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.
