Question

1. what are the functions of the following organelles? what cell will they be found in, plants or animals?:

nucleus:
mitochondria:
golgi apparatus:
lysosome:
large central vacuole:
endoplasmic reticulum:
rough er:
smooth er:
ribosome:
cell wall:
flagella:
cytoplasm:

Explanation:

• Nucleus: Stores genetic material (DNA), controls cell activities. Found in both plant and animal cells.
• Mitochondria: Produces energy (ATP) through cellular respiration. Found in both plant and animal cells.
• Golgi apparatus: Modifies, sorts, and packages proteins and lipids. Found in both plant and animal cells.
• Lysosome: Contains digestive enzymes to break down waste materials. Found in animal cells (rare in plant cells).
• Large Central Vacuole: Stores water, nutrients, and waste; provides turgor pressure. Found in plant cells.
• Endoplasmic Reticulum (ER): General role in protein and lipid synthesis. Found in both plant and animal cells.
• Rough ER: Studded with ribosomes, involved in protein synthesis.
• Smooth ER: Involved in lipid synthesis and detoxification.
• Ribosome: Site of protein synthesis. Found in both plant and animal cells.
• Cell wall: Provides structural support and protection. Found in plant cells.
• Flagella: Aids in cell movement. Found in some animal cells (e.g., sperm) and some single - celled organisms (not typical in most plant cells).
• Cytoplasm: Holds organelles, site of many cellular processes. Found in both plant and animal cells.

Answer:

• Nucleus: Function - stores DNA, controls cell activities. Cell type - both.
• Mitochondria: Function - energy production (ATP). Cell type - both.
• Golgi apparatus: Function - modifies, sorts, packages. Cell type - both.
• Lysosome: Function - digestion. Cell type - animal (rare in plant).
• Large Central Vacuole: Function - storage, turgor. Cell type - plant.
• Endoplasmic Reticulum: Function - synthesis. Cell type - both.
• Rough ER: Function - protein synthesis.
• Smooth ER: Function - lipid synthesis, detoxification.
• Ribosome: Function - protein synthesis. Cell type - both.
• Cell wall: Function - support, protection. Cell type - plant.
• Flagella: Function - movement. Cell type - some animal (e.g., sperm).
• Cytoplasm: Function - holds organelles, site of processes. Cell type - both.
