Question

part 1: matching
directions: match organelles in left-hand column with the function from the right-hand column. (10)

1. cell membrane a. the control center of a cell that contains dna
2. cytoplasm b. digest waste and excess materials in the cell
3. ribosome c. produces lipids to build the cell membrane
4. cytoskeleton d. converts food into usable energy for the cell
5. nucleus e. converts sunlight and co₂ into sugar and o₂
6. rough e.r. f. network of filaments that maintains the cells shape
7. smooth e.r. g. produces proteins from rna and amino acids
8. golgi apparatus h. storage compartment for water, salt, and carbohydrates
9. mitochondria i. protective barrier of plant cells and most bacteria cells
10. vacuole j. controls what enters and leaves all cells
11. lysosome k. stores water and provides structural support to plant
12. centrioles l. organize and separate chromosomes during cell
13. cell wall m. portion of cell outside the nucleus where organelles
14. chloroplast n. packages and ships materials around the cell
15. central vacuole o. aids in production, modification, and export

Explanation:

Each organelle is matched to its core cellular function based on basic cell biology principles.

1. Cell Membrane controls substance movement in/out of cells.
2. Cytoplasm is the area outside the nucleus where organelles reside.
3. Ribosomes synthesize proteins from RNA and amino acids.
4. Cytoskeleton maintains cell shape via filament networks.
5. Nucleus is the cell's control center holding DNA.
6. Rough E.R. aids in protein production/modification/export.
7. Smooth E.R. produces lipids for cell membranes.
8. Golgi Apparatus packages and ships cellular materials.
9. Mitochondria convert food into usable cell energy.
10. Vacuole stores water, salts, and carbohydrates.
11. Lysosome digests cell waste and excess materials.
12. Centriole organizes/separates chromosomes during cell division.
13. Cell Wall is the protective barrier for plant/bacterial cells.
14. Chloroplast converts sunlight/CO₂ into sugar/O₂.
15. Central Vacuole stores water and supports plant structure.
