Unit 1 Organelles

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

Organelle
Function
Nucleus   -Found in eukaryotic cells -Has a double membrane -Control the cells activities -Contain the cells DNA -Hold instructions for making new cells/organisms  
🗑
Nucleolus   -Found in eukaryotic cells -Sits inside the nucleus -Produces ribosomes  
🗑
Nuclear Envelope   -Found in eukaryotic cells -Provides a structural framework for the nucleus -Controls the movement of substances in and out of the cell  
🗑
Nuclear Pores   -Found in eukaryotic cells -Protein lined channel found in the nuclear envelope -Regulates the transportation of molecules between the nucleus and the cytoplasm  
🗑
Cell Wall   -Found in both eukaryotic (plant only) and prokaryotic cells -They are rigid and strong -Support the cell  
🗑
Cell Membrane   -Found in only eukaryotic cells -Controls the movement of materials in and out of the cell -Acts as a barrier  
🗑
Cytoplasm   -Found in both eukaryotic and prokaryotic cells -Clear, thick jelly-like substance -Contains the organelles -Chemical reactions takes place here  
🗑
Ribosomes   -Found in both eukaryotic and prokaryotic cells -Can be found floating around the cytoplasm (E+P) -Can be found attached to the rough ER (E) -Where protein synthesis takes place  
🗑
Mitochondria   -Found in eukaryotic cells -Bean shaped organelles found in the cytoplasm -Where respiration takes place  
🗑
Vacuole   -Found in eukaryotic cells -Fluid filled sac used to store food, water, and waste -Used to keep the cell rigid in plant cells  
🗑
Lysosome   -Found in eukaryotic cells (rarely plants) -Found in the cytoplasm and contain degradation enzymes -Digests things such as old cell parts  
🗑
Chloroplasts   -Found in eukaryotic cells (plants only) -Contain chlorophyll -Where photosynthesis takes place  
🗑
Golgi Body   -Found in eukaryotic cells -Responsible for manufacturing, storing and shipping cellular products  
🗑
Peroxisomes   -Found in eukaryotic cells -Contain enzymes to help break down fatty acids and substances  
🗑
Rough Endoplasmic Reticulum   -Found in eukaryotic cells -Involved in the storage and transport of proteins synthesized by the ribosomes attached  
🗑
Smooth Endoplasmic Reticulum   -Found in eukaryotic cells -Involved in the production & metabolism of fats and steroid hormones  
🗑
Centrioles   -Found in eukaryotic cells (animal only) -Small set of micro tubules -Play a major part in mitosis  
🗑
Cytoskeleton   -Found in eukaryotic cells -Structure that helps maintain a cells shape & internal organisation -Provides mechanical support -Helps cells carry out functions such as movement and division  
🗑


   

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.
