Solved CELLS alive! - Animal Cell Worksheet 1) 2) 3) 4) 5) | Chegg.com - Free Printable

I can't view or analyze images directly, but I can help you solve the "CELLS alive! - Animal Cell Worksheet" if you provide the labels or describe what each numbered part is pointing to in the diagram.

However, based on typical animal cell diagrams and the standard structure of an animal cell, here’s a likely labeling for the 15 parts (assuming the diagram is a standard animal cell):

Here are the most common organelles and structures found in an animal cell:

1. Nucleus – The control center of the cell; contains DNA.
2. Nuclear membrane (or nuclear envelope) – Double membrane surrounding the nucleus.
3. Nucleolus – Structure inside the nucleus that produces ribosomes.
4. Ribosome – Site of protein synthesis; may be free or attached to the ER.
5. Golgi apparatus – Modifies, sorts, and packages proteins and lipids.
6. Mitochondrion – Site of cellular respiration; produces ATP (energy).
7. Endoplasmic Reticulum (ER) – Network of membranes; rough ER has ribosomes, smooth ER does not.
8. Lysosome – Contains digestive enzymes to break down waste materials.
9. Centriole – Involved in cell division; helps organize microtubules.
10. Cytoskeleton – Network of fibers providing shape and movement (microfilaments, intermediate filaments, microtubules).
11. Vesicle – Small sac that transports materials within the cell.
12. Cell membrane (plasma membrane) – Regulates what enters and exits the cell.
13. Smooth Endoplasmic Reticulum (SER) – Lacks ribosomes; involved in lipid synthesis and detoxification.
14. Rough Endoplasmic Reticulum (RER) – Has ribosomes; involved in protein synthesis.
15. Cytoplasm – Gel-like substance filling the cell; where organelles are suspended.

Step-by-step guide to matching:

Look at the diagram and match the numbers with the following:
- The large blue circle is the nucleus (1).
- Inside the nucleus, the small dark spot is the nucleolus (3).
- The double membrane around the nucleus is the nuclear membrane (2).
- The stacked flattened sacs near the nucleus are the Golgi apparatus (5).
- The small green oval structures are mitochondria (6).
- The network of tubes near the nucleus may be the endoplasmic reticulum (7 or 14).
- The tiny dots on the ER are ribosomes (4).
- The small round structures with enzymes are lysosomes (8).
- The two small cylindrical structures near the nucleus are centrioles (9).
- The outer boundary of the cell is the cell membrane (12).
- The small vesicles moving around are vesicles (11).
- The gel-like area surrounding the organelles is the cytoplasm (15).

If you can tell me which number corresponds to which structure in your image, I can give you exact answers. But this list should help you fill in the worksheet correctly.
