Question

a tour inside the cell
lets do a recap of the structures discovered inside the cell after the video tour! fill in the below chart to help you organize what weve visited. remember there are more functions and structures that you can discover online.

structure or organelle on the tour	makes me think of... (provide an illustration or analogy)	function(s)	type of cell? is it in both prokaryotes and eukaryotes? or just eukaryotes?
cytoplasm	17.	18.	19.
ribosome	20.	21.	22.
nucleus	23.	24.	25.
endoplasmic reticulum (rough and smooth)	26.	27.	28.
golgi apparatus	29.	30.	31.
mitochondria (singular: mitochondrion)	32.	33.	eukaryotic cells (in both animal and plant cells)
cell wall	34.	35.	36.
chloroplast	37.	38.	39.
vacuole	40.	41.	42.

Explanation:

1. A cell membrane can be thought of as a security guard at a building entrance, controlling what enters and leaves.
2. It regulates the movement of substances in and out of the cell, provides protection, and maintains cell - shape.
3. Both prokaryotes and eukaryotes.
4. Cytoplasm is like the jelly - like filling in a donut, holding everything in place.
5. It is the site of many metabolic reactions and suspends organelles.
6. Both prokaryotes and eukaryotes.
7. Ribosomes are like tiny factories that make proteins.
8. They are the sites of protein synthesis.
9. Both prokaryotes and eukaryotes.
10. The nucleus is like the control center of a city, housing the cell's genetic material.
11. It stores DNA, controls cellular activities, and is involved in cell division.
12. Eukaryotes only.
13. The endoplasmic reticulum is like a highway system for transporting materials within the cell.
14. Rough ER is involved in protein synthesis and transport, smooth ER in lipid synthesis and detoxification.
15. Eukaryotes only.
16. The Golgi apparatus is like a post - office, modifying, sorting, and packaging proteins and lipids.
17. It modifies, sorts, and packages proteins and lipids for secretion or use within the cell.
18. Eukaryotes only.
19. The cell wall is like a fortress wall, providing structural support and protection.
20. It provides support, protection, and helps maintain cell shape.
21. Prokaryotes (in bacteria) and some eukaryotes (plants and fungi).
22. Chloroplasts are like solar panels, converting light energy into chemical energy.
23. They are the sites of photosynthesis, converting light energy to chemical energy in the form of glucose.
24. Eukaryotes (plants only).
25. A vacuole is like a storage tank, storing water, nutrients, and waste.
26. It stores water, nutrients, waste products, and helps maintain turgor pressure in plant cells.
27. Eukaryotes (more prominent in plant cells).
