The contents of sub-cellular structures found in eukaryotic cells enable each structure to perform its specific function.
Draw lines to connect each sub-cellular structure to its key component/contents. Then draw lines to join each of the key component/contents to its correct function within the cell.
| Sub-cellular structure | Key component/contents | Function |
|---|---|---|
| Mitochondria | Phospholipid bilayer | Controls the entry and exit of substances |
| Chloroplast | Folded inner membrane with enzymes | Absorbs light for photosynthesis |
| Cell membrane | Thylakoids containing chlorophyll | Releases energy during aerobic respiration |
b.[2]
The image shows a micrograph of a mitochondrion.
Draw the mitochondrion. Your drawing should be a simplified scientific drawing.
c.[2]
What type of microscope was used to create the image of the mitochondrion? Explain your answer.
d.[1]
Name one structure found in both an animal cell and a prokaryotic cell, other than a cell membrane.
