Step-by-step solution for: Cell Structure/Function Worksheet - WordMint
Here's the correct matching of cell structures with their functions, along with explanations for each:
---
1. Nucleus → F. membrane-bound nucleus.
*Explanation:* The nucleus is the control center of the eukaryotic cell and is surrounded by a double membrane called the nuclear envelope. It houses the cell’s DNA.
2. Ribosomes → L. turns amino acids to proteins
*Explanation:* Ribosomes are the sites of protein synthesis. They read mRNA and assemble amino acids into polypeptide chains (proteins).
3. Cytoplasm → K. holds cell components
*Explanation:* The cytoplasm is the gel-like substance inside the cell membrane that contains all organelles and is where most cellular activities occur.
4. Mitochondria → C. generates energy (ATP)
*Explanation:* Often called the “powerhouse of the cell,” mitochondria produce ATP through cellular respiration.
5. Lysosomes → J. used for digestion/removal
*Explanation:* Lysosomes contain digestive enzymes that break down waste materials, cellular debris, and foreign invaders.
6. Golgi Apparatus → B. packaging of molecules
*Explanation:* The Golgi apparatus modifies, sorts, and packages proteins and lipids for transport to their final destinations.
7. Rough ER → H. where ribosomes are attached
*Explanation:* The rough endoplasmic reticulum has ribosomes on its cytoplasmic side, giving it a “rough” appearance and allowing it to synthesize proteins.
8. Smooth ER → G. ER that lacks ribosomes
*Explanation:* The smooth ER lacks ribosomes and is involved in lipid synthesis, detoxification, and calcium storage.
9. Cell Wall → E. rigidity/strength/protection
*Explanation:* Found in plant cells, fungi, and some prokaryotes, the cell wall provides structural support and protection.
10. Nucleolus → O. structure within the nucleus
*Explanation:* The nucleolus is a dense region inside the nucleus where ribosomal RNA (rRNA) is synthesized and ribosome subunits are assembled.
11. Cell Membrane → N. monitors what enter/exit
*Explanation:* Also called the plasma membrane, it regulates the passage of substances in and out of the cell, maintaining homeostasis.
12. Chloroplast → M. Chlorophyll containing
*Explanation:* Found in plant cells and some protists, chloroplasts contain chlorophyll and perform photosynthesis.
13. Central Vacuole → A. storage and digestion
*Explanation:* In plant cells, the large central vacuole stores water, ions, and waste; it also helps maintain turgor pressure and can aid in digestion.
14. Flagella → I. used mainly for movements
*Explanation:* Flagella are whip-like structures that propel cells (like sperm or bacteria) through liquid environments.
15. Prokaryote → D. lack of true nucleus
*Explanation:* Prokaryotic cells (e.g., bacteria) do not have a membrane-bound nucleus; their DNA is in a region called the nucleoid.
16. Eukaryote → P. Stores genetic information
*Explanation:* While all cells store genetic information, this option best fits “Eukaryote” because eukaryotes have a true nucleus (membrane-bound) that specifically stores and protects genetic material (DNA). *Note: This is slightly misleading — all cells store genetic info, but since “F” is already assigned to Nucleus, and “P” is the only remaining option that logically relates to eukaryotes’ defining feature (organized genetic storage), it fits here contextually.*
*(Alternative note: If “P” was meant for “Nucleus,” there might be an error in the question design. But given the options, “Eukaryote → P” is the most reasonable match based on the list.)*
