|---|---|---|---|---|---|
| unicellular | an organism made of one cell (ex- bacteria)
🗑
|
||||
| multicellular | an organism composed of more than one cell
🗑
|
||||
| cell | the basic unit (of structure and function) in living things
🗑
|
||||
| organelle | a tiny cell structure or part that carries out a specific job in the cell
🗑
|
||||
| cell wall | a strong or rigid layer that surrounds the cells of plants; provides shape, support, and strength
🗑
|
||||
| cell membrane | a cell part that controls which substances can enter or leave the cell
🗑
|
||||
| nuclear membrane | protects the nucleus and allows materials to pass into and out of the nucleus
🗑
|
||||
| nucleus | directs and controls all cell activity
🗑
|
||||
| chromosomes | contain the DNA or genetic material
🗑
|
||||
| nucleolus | where ribosomes are made
🗑
|
||||
| ribosome | where proteins are made
🗑
|
||||
| endoplasmic reticulum (E.R.) | passageways that carry or transport protein and other materials from one part of the cell to another
🗑
|
||||
| golgi bodies | receive proteins and other materials and packages them, and distributes them to other parts of the cell
🗑
|
||||
| mitochondria | an organelle that uses food molecules and changes it into energy for the cell to use
🗑
|
||||
| chloroplasts | found only in plant cells that captures energy from the sun to be used in photosynthesis
🗑
|
||||
| vacuole | stores food, water, and wastes in a cell; it is larger in plant cells
🗑
|
||||
| lysosome | this is found only in animal cells; contains chemicals to help break down food and old cell parts
🗑
|
||||
| centrosome | found only in animal cell; organelle that helps in cell division
🗑
|
||||
| cytoplasm | gel-like fluid that holds other organelles
🗑
|
||||
| water | this is not an organelle but cells need this for chemical reactions to occur, to move substances around, to regulate temperature, and to maintain size and shape
🗑
|
||||
| tissue | a group of similar cells that work together to do a specific function or job
🗑
|
||||
| organ | different kinds of tissue that work together to perform a function
🗑
|
||||
| organ system | groups of organs that work together to perform a major function
🗑
|
||||
| First you have a cell...then cells come together to form a tissue...then tissues come together to form... | an organ ....organs come together to form organ systems
🗑

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.
