Cell organelles and their functions

Quiz yourself by thinking what should be in each of the black spaces below before clicking on it to display the answer.
        Help!  

Question
Answer
nucleus   directs the cell’s activities  
🗑
cell membrane   “gatekeeper” of the cell; controls what enters and leaves the cell  
🗑
lysosome   contains chemicals that break down food and worn out cell parts  
🗑
endoplasmic reticulum (ER)   transports proteins and other materials through the cell  
🗑
mitochondrion   “powerhouse” of the cell; produces energy used by the cell from glucose  
🗑
ribosomes   small structures where proteins are produced  
🗑
vacuole   storage sac for water, nutrients, and waste  
🗑
cell wall   a rigid layer of non-living material that surrounds the cell; provides protection and support  
🗑
chloroplast   captures energy from the sun to produce food (glucose)  
🗑
cytoplasm   gel-like material between the cell membrane and the nucleus; holds the organelles  
🗑
nucleolus   organelle inside the nucleus where ribosomes are made  
🗑
chromatin (chromosome)   contain the cell’s genetic material  
🗑
Golgi body   receive materials from the ER and packages them for transport within or outside the cell  
🗑
nuclear membrane   controls what enters and exits the cell’s nucleus  
🗑


   

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.
