Question

3 name 2 structures that are common to both prokaryotes & eukaryotes. 4 for the given structures, list their name and function. 5 for the given structures, list their name and function. 6 for the given structures, list their name and function.

Explanation:

1. Prokaryotes and eukaryotes both have cell - membranes which act as a barrier controlling the movement of substances in and out of the cell, and ribosomes which are involved in protein synthesis.
2. Without seeing the specific structures, a general approach is to identify organelles like mitochondria (power - house of the cell, producing ATP) and endoplasmic reticulum (involved in protein and lipid synthesis).
3. Without seeing the specific structures, if it's a plant cell, for example, 1 could be a chloroplast (site of photosynthesis) and 2 could be a large central vacuole (stores water, nutrients and waste).
4. Without seeing the specific structures, 1 could be the Golgi apparatus (modifies, sorts and packages proteins and lipids) and 2 could be a lysosome (contains digestive enzymes to break down waste materials).

Answer:

1. Cell - membrane: Controls substance movement; Ribosome: Protein synthesis.
2. N/A (No structures shown to identify).
3. N/A (No structures shown to identify).
4. N/A (No structures shown to identify).
