|---|---|---|---|---|---|
| Organelle | any of a number of organized or specialized structures within a living cell.
🗑
|
||||
| Cytoplasm | the material or protoplasm within a living cell, excluding the nucleus.
🗑
|
||||
| Nucleus | a dense organelle present in most eukaryotic cells, typically a single rounded structure bounded by a double membrane, containing the genetic material.
🗑
|
||||
| Nuclear Envelope | surrounds the genetic material and nucleolus in eukaryotic cells
🗑
|
||||
| Chromatin | The DNA double helix in the cell nucleus is packaged by special proteins termed histones
🗑
|
||||
| Chromosome | a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes
🗑
|
||||
| Nucleolus | a small dense spherical structure in the nucleus of a cell during interphase
🗑
|
||||
| Ribosome | a minute particle consisting of RNA and associated proteins, found in large numbers in the cytoplasm of living cells. They bind messenger RNA and transfer RNA to synthesize polypeptides and proteins
🗑
|
||||
| Endoplasmic Reticulum | a network of membranous tubules within the cytoplasm of a eukaryotic cell, continuous with the nuclear membrane. It usually has ribosomes attached and is involved in protein and lipid synthesis
🗑
|
||||
| Golgi Apparatus | 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
🗑
|
||||
| Cytoskeleton | a microscopic network of protein filaments and tubules in the cytoplasm of many living cells, giving them shape and coherence
🗑
|
||||
| Centrioles | a minute cylindrical organelle near the nucleus in animal cells, occurring in pairs and involved in the development of spindle fibers in cell division
🗑
|
||||
| Vacuole | a space or vesicle within the cytoplasm of a cell, enclosed by a membrane and typically containing fluid
🗑
|
||||
| Mitochondrion | an organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur
🗑
|
||||
| Chloroplasts | a plastid that contains chlorophyll and in which photosynthesis takes place
🗑
|
||||
| Cell Wall | a rigid layer of polysaccharides lying outside the plasma membrane of the cells of plants, fungi, and bacteria. In the algae and higher plants, it consists mainly of cellulose
🗑
|
||||
| Cell Membrane | the semipermeable membrane surrounding the cytoplasm of a cell
🗑
|
||||
| Selectively Premeable | a type of biological or synthetic, polymeric membrane that will allow certain molecules or ions to pass through it by diffusion
🗑

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.
