|---|---|---|---|---|---|
| cell wall | a structure that surrounds the cell membrane and provides support to the cell
🗑
|
||||
| cytoplasm | the jelly-like fluid inside the cell - mostly water
🗑
|
||||
| nucleus | a large organelle in a eukaryotic cell that contains the cell's DNA/chromosomes/genetic material
🗑
|
||||
| ribosomes | non membrane-bounded organelles that are responsible for making proteins
🗑
|
||||
| mitichondria | the organelles that break down food/sugar to release energy
🗑
|
||||
| endoplasmic reticulum | rough ER transports proteins around the cell, and contains ribosomes; smooth ER acts as a pathway through the cell, and contains no ribosomes
🗑
|
||||
| golgi bodies | the organelle that packages proteins and lipids before sending them through the cell; they also take part in secretion
🗑
|
||||
| vacuole | the organelles that store waste, water and other materials
🗑
|
||||
| chromoplasts | organelles that contain pigments (chlorophyll) used in photosynthesis
🗑
|
||||
| centrioles | are involved in cellular reproduction/division
🗑
|
||||
| middle lamella | thin film between cell walls of adjacent plant cells, made mostly of pectin
🗑
|
||||
| lysosome | organelle in animal cells responsible for hydrolosis reactions that break down proteins, polysaccharides, disaccharides and some lipids
🗑
|
||||
| leucoplasts | organelles that store the starches left over from photosynthesis
🗑
|
||||
| cytoskeleton | network of fibers that holds the cell together and aids the cell in movement
🗑
|
||||
| plasma membrane | semipermeable membrane between the cell's contents and either the cell wall or the cell's surroundings
🗑

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.
