|---|---|---|---|---|---|
| cell membrane | the semipermeable membrane surrounding the cytoplasm of a cell.
🗑
|
||||
| cell wall | is a tough, flexible and sometimes rigid layer that surrounds some types of cells. It surrounds the cell membrane and provides these cells with structural support and protection.
🗑
|
||||
| cellular respiration | the set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products.
🗑
|
||||
| chloroplast | are the food producers of the cell. The organelles are only found in plant cells and some protists such as algae. Animal cells do not have chloroplasts. Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells.
🗑
|
||||
| chromatin | s a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells.
🗑
|
||||
| chromosome | is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.
🗑
|
||||
| cristae | providing a large amount of surface area for chemical reactions to occur on.
🗑
|
||||
| cytoplasm | is a thick solution that fills each cell and is enclosed by the cell membrane. It is mainly composed of water, salts, and proteins.
🗑
|
||||
| cytoskeleton | is a structure that helps cells maintain their shape and internal organization,
🗑
|
||||
| Golgi bodies | a complex of vesicles and folded membranes within the cytoplasm of most eukaryotic cells, involved in secretion and intracellular transport.
🗑
|
||||
| lysosome | an organelle in the cytoplasm of eukaryotic cells containing degradative enzymes enclosed in a membrane.
🗑
|
||||
| matrix | is more viscous than the cell's cytoplasm as it contains less water.
🗑
|
||||
| mitochondria | in which the biochemical processes of respiration and energy production occur
🗑
|
||||
| nuclear envelope | is the double lipid bilayer membrane which surrounds the genetic material and nucleolus in eukaryotic cells.
🗑
|
||||
| nuclear pore | is a protein-lined channel in the nuclear envelope that regulates the transportation of molecules between the nucleus and the cytoplasm.
🗑
|
||||
| nucleolus | is the nuclear subdomain that assembles ribosomal subunits in eukaryotic cells.
🗑
|
||||
| nucleus | control center
🗑
|
||||
| organelle | typically have their own plasma membrane round them. Most of the cell's organelles are in the cytoplasm.
🗑
|
||||
| polysome | is a complex of a mRNA molecule and two or more ribosomes that is formed during active translation.
🗑
|
||||
| ribosome | is a complex of over 50 proteins plus its own complement of RNA, often denoted rRNA.
🗑
|
||||
| rough endoplasmic reticulum | are responsible for the assembly of many proteins
🗑
|
||||
| smooth endoplasmic reticulum | associated with the production and metabolism of fats and steroid hormones.
🗑
|
||||
| vacuole | are storage bubbles found in cells
🗑
|
||||
| vesicle | is a small structure within a cell, consisting of fluid enclosed by a lipid bilayer membrane.
🗑

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.
