Explanation:
Hi, so this diagram is obviously a diagram of a eukaryotic cell. (It's not prokaryotic since there are many organelles, and there is a nucleus). From more observing, we see that it's a plant cell (There are cell walls around the cell, which animals cells don't have).
So anyways, onto the labeling.
So beforehand, we saw that this is a plant cell, which helps us in labeling. Plant cells have certain organelles animal cells don't have.
I bolded the answers, and I started with the top left box and went clockwise around the diagram.
For the label top left next to the word 'Cell', you would put plant, or eukaryotic. I would say plant, since that would be more specific.
Next to the word 'Cell', there is another label pointing to the purple structure. This is the Golgi apparatus, where vesicles drop off proteins and other substances for modification. (Think of it like the 'packaging center'). You can tell because the 'purple structures' are not connected.
Next to that label we have another one pointing to the clear and bluish big blobby like structure. That is the vacuole. The vacuole stores wastes, water, and can enlarge or become smaller.
Next to that box we have another one pointing to the blue structure. The answer is the nucleus. Just think of it as the 'directory' of the cell.
After, next to the previous box, on the top right, that box is pointing to a purple structure. Light purple actually. This is the smooth endoplasmic reticulum, or ER. It's usually next to the nucleus and the rough ER, which we'll talk about afterwards.
On the box below the previous, pointing to the small dots, those are the ribosomes. To clarify, ribosomes are NOT organelles. They make proteins for the cell, and can be found on the rough ER.
Coming to the bottom right, that box is pointing to a red structure, or the rough ER (endoplasmic reticulum). They have ribosomes on their surface, unlike the smooth ER.
For the next box, it would be the cell wall. I thought it was the cell membrane at first, but no it isn't. The things sticking out from the diagram are also cell walls, but from other plant cells.
The next box points to the green organelle, or the chloroplast. It contains chlorophylls which give the green color to plants.
On the next box we have it pointing to the yellow structure(light yellow). I'm not sure what to call it, but that is the cell membrane. This is different from the cell wall, because it surrounds the whole cell. (If you trace the very outer light green wall, you will see that it doesn't surround the whole cell).
The box pointing to the yellow structure with the blue lines inside is the mitochondria. It is the 'powerhouse of the cell', where cellular respiration takes place.
The next box is pointing to the light green space. That is the cytoplasm, which consists of the cytosol. It's a jelly like substance that is mostly consisted of water.
Finally, for the last box, I am not really sure what it is, as it looks like it is also pointing to the cell membrane. I would answer plasma membrane. It's composed of phospholipids and other proteins.
Hopefully this helps you!
