CELL QUESTION 1984: L. PETERSON/AP BIOLOGY
Describe the structure of a generalized eukaryotic plant cell. Indicate the ways
in which a nonphotosynthetic prokaryotic cell would differ in structure from
this generalized eukaryotic plant cell.
STANDARDS:
STRUCTURE, as part of the eukaryotic cell: DESCRIPTION:
(1/2 point each) (1 point each)
__ Cell Wall __ Cellulose
__ Cell Membrane __ Protein/phospholipid or
phospholipid bilayer
__ Cytoplasm __ Fluid with dissolved substances
__ Vacuole __ Protein/phospholipid or water
__ Mitochondria __ Cristae, folding convolutions
__ Ribosomes __ Two Subunits
__ Golgi Bodies __ Phospholipid/protein, cisternae, vesicles
__ Chloroplasts __ Stroma, grana, thylakoids
__ Lysosomes __ Phospholipid/protein membrane
or digestive enzyme
__ Nucleus __ Double nuclear membrane or
envelope
__ Nucleolus __ RNA present, fibrillar
__ Chromosome __ Double strand, DNA and Protein
__ Plasmodesmata __ Cytoplasmic bridge
__ Peroxisomes __ Membrane Bound
__ Flagella __ 9 + 2
__ Microtubules, microfilaments __ Tubulin protein/actin protein
MAX. = 4 points MAX. = 7 points
TOTAL MAXIMUM = 10 points
II. STRUCTURE COMPARISONS/DIFFERENCES of a
simple cell and a complex cell.
(2 points each pair / structure and comparison)
__ Cell Wall __ No cellulose; murein present
__ Cell Membrane __ No cholesterol
__ Membrane-bound organelles absent __ Name one organelle
__ OR AT LEAST 2: vacuole, mitochondria, __ Absent
nucleus, E.R., lysosome, peroxisome,
chloroplast
__ AT LEAST 2: microtubules, microfilaments, __ Absent
plasmodesmata
__ Ribosomes __ Smaller, few, free floating
__ Nuclear membrane __ Absent
__ Genetic material __ Single, no protein, circular,
plasmids
__ Flagella __ No 9 + 2
BONUS: Elaboration: evolution, size, two additional structures and comparisons for
each structure = one point each
MAXIMUM = 10 points in Section II.
