Question

bio.1c students will relate the diversity of organelles to a variety of specialized cellular functions.
bio.1c.1 develop and use models to explore how specialized structures within cells (e.g., nucleus,
cytoskeleton, endoplasmic reticulum, ribosomes, golgi apparatus, lysosomes, mitochondria, chloroplast,
centrosomes, and vacuoles) interact to carry out the functions necessary for organism survival.

Explanation:

To solve this, we analyze each organelle's function and presence in animal/plant cells:

Nucleus

• Purpose: Contains genetic material (DNA), controls cell activities (e.g., growth, reproduction).
• Animal/Plant/Both: Both (present in eukaryotic animal and plant cells).

Cytoskeleton

• Purpose: Provides structural support, aids in cell movement, and helps in intracellular transport.
• Animal/Plant/Both: Both (found in all eukaryotic cells).

Endoplasmic Reticulum (ER)

• Purpose: Rough ER (with ribosomes) synthesizes proteins; Smooth ER synthesizes lipids, detoxifies, and stores calcium.
• Animal/Plant/Both: Both (present in eukaryotic cells).

Ribosomes

• Purpose: Site of protein synthesis (translates mRNA into proteins).
• Animal/Plant/Both: Both (found in all cells, prokaryotic and eukaryotic; in eukaryotes, free in cytoplasm or on ER).

Golgi Apparatus

• Purpose: Modifies, sorts, and packages proteins and lipids for transport (e.g., to cell membrane, lysosomes, or secretion).
• Animal/Plant/Both: Both (present in eukaryotic cells).

Lysosomes

• Purpose: Contains digestive enzymes to break down waste, damaged organelles, or foreign invaders (e.g., bacteria).
• Animal/Plant/Both: Animal (rare in plant cells; plants use vacuoles for similar functions).

Mitochondria

• Purpose: Produces ATP (energy) via cellular respiration.
• Animal/Plant/Both: Both (present in eukaryotic cells; "powerhouse of the cell").

Chloroplast

• Purpose: Performs photosynthesis (converts light energy into chemical energy - glucose).
• Animal/Plant/Both: Plant (only in photosynthetic eukaryotes like plants and algae).

Centrosomes

• Purpose: Involved in cell division (forms spindle fibers in animal cells).
• Animal/Plant/Both: Animal (plant cells have different microtubule - organizing centers).

Vacuoles

• Purpose: In animal cells: stores waste, nutrients, or water (small). In plant cells: large central vacuole stores water, maintains turgor pressure, stores nutrients/waste.
• Animal/Plant/Both: Both (plant vacuoles are larger and more prominent).
