Explanation: 

Detailed explanation-1: -The chloroplast of spirogyra is long, spirally coiled ribbon shaped with pyrenoids.

Detailed explanation-2: -Chloroplasts are a type of plastid-a round, oval, or disk-shaped body that is involved in the synthesis and storage of foodstuffs. Chloroplasts are distinguished from other types of plastids by their green colour, which results from the presence of two pigments, chlorophyll a and chlorophyll b.

Detailed explanation-3: -Spirogyra has thin and flat ribbon-shaped chloroplasts. These chloroplasts are spirally coiled in the structure.

Detailed explanation-4: -Chlamydomonas have cup – shaped chloroplasts. The correct answer is A-Cup shaped. Chlamydomonas species are mostly used as models for research purposes in cell biology and molecular biology for fundamental questions studies of flagellar motility, chloroplast dynamics, genetics, and biogenesis.
