|---|---|---|---|---|---|
| What is a cell | the smallest unit taht can perform all necessary functions of life
🗑
|
||||
| What did robert hook do? | discovered cells thought plants had juice incorecctly assumed animals didnt have cells
🗑
|
||||
| Response to stimuli | response to surrounding environment
🗑
|
||||
| the theory | all organisims made of at least 1 or more cells A cell is the basic untit of life all cells come from existing cells
🗑
|
||||
| 4 things all cells have | cell membrane organelles cytoplasm dna
🗑
|
||||
| what are the 2 types of organism | prokariotic and eukariotic
🗑
|
||||
| wat is the difference between prokaryotic and eukaryotic cells | eukariotic cells have a nucleous which has the dna in it and prokariotic cells have the dna in the cytoplasm
🗑
|
||||
| cell membrane | outer layer incloses the cell allows nutrients and water in but keeps unwanted meterial out and lets waste out it also recieves and transits message its flexible sei permeable and has parts that like water and some that dont
🗑
|
||||
| cell wall | supports the cell outer layer in plant cells not in animal cells made of sugars called cellulose and chitin and its rigid
🗑
|
||||
| cytoskeleten | support and structure gives cell its shape allows cell to move pathway to organelles made of 3 proteins stringy/thready tubes and rigid threads
🗑
|
||||
| Nucleus | control center for all activities holds dna and sends messages to the rest of the cell double memrane for protection doesnt let dna out
🗑
|
||||
| Ribosomes | make proteins and decode genes samll no membrane alot of them in every cell some attachted to ER
🗑
|
||||
| ER | rough = to help make proteins Smooth = make other important things both = deliver things throughout cell attached to nuclear mumbrane ribosomes attached folded membrane and tube
🗑
|
||||
| mitochandria | power the cell brake down sugars into energy stores atp double membrane folded inside own dan large many in cells that need energy
🗑
|
||||
| chloroplasts | power cell makes sunlight into sugar and oxygen phtosynthesis happpens only in plant green b/c of chlorophyll have own dna
🗑
|
||||
| golgi complex | membrane that pinches stuff to hold the packages bubbles of packages go throughout the cell
🗑
|
||||
| lysosomes | kind of vesicle uses enzymes to break down unwanted organelles and waste different shapes and sizes
🗑
|
||||
| vacuole | vesicle large central vesicle stores water helps support the cell like a huge bubble
🗑

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.
