Detailed explanation-1: -Complete answer :A cup shaped chloroplast is present in Chlamydomonas . A cup-shaped chloroplast has a single pyrenoid where starch is formed from the photosynthetic products. In cup-shaped chloroplast, the nucleus is enclosed within it.

Detailed explanation-2: -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.

Detailed explanation-3: -Chlamydomonas is a small, unicellular green alga. The spherical, ovoid, or ellipsoidal cells have two equal, anterior flagella with two contractile vacuoles at their base. A single parietal, cup-shaped chloroplast with one or several pyrenoids occupies much of the cell.

Detailed explanation-4: -Chlamydomonas is unicellular green algae. The shape of Chlamydomonas chloroplast is cup-shaped.

Detailed explanation-5: -Chlamydomonas possess cup-shaped chloroplast, whereas Ulothrix possess girdle-shaped chloroplast. Likewise, Spirogyra possess spiral shaped chloroplasts.
