Types of Sexual Reproduction — NEET Biology
🔥 Predicted for NEET 2027Sexual reproduction may be isogamous, anisogamous or oogamous. Union of gametes may take place in water or within the oogonium (oogamous species). The gametes are pyriform (pear-shaped) and bear two laterally attached flagella. The common forms are Ectocarpus, Dictyota, Laminaria, Sargassum and Fucus.
Adjacent to a frequently-asked paragraph in the same chapter.
Consider the following statements : 1. Chlamydomonas belongs to Chlorophyceae; it contains chlorophyll a and b, stores food as starch, and has a cell wall made of cellulose. 2. Laminaria is a brown alga (Phaeophyceae); it contains chlorophyll a, c and fucoxanthin, stores mannitol and laminarin, and has a cell wall of cellulose + algin. 3. Porphyra is a red alga (Rhodophyceae); it has pigments chlorophyll a, d and phycoerythrin, stores floridean starch, and lacks flagella. 4. Ulothrix belongs to Chlorophyceae; it possesses apical, equal flagella, starch in pyrenoids, and occurs in fresh water. 5. Sargassum is a brown alga (Phaeophyceae); it has fucoxanthin pigment, stores laminarin, and grows in marine habitats. Which of the above statements are correct?
View solution & NCERT explanation
Correct answer: C — 1, 2, 3, 4 and 5
Statement 1 → Chlamydomonas = Chlorophyceae, has chlorophyll a & b, stores starch, cellulose wall. Statement 2 → Laminaria = Phaeophyceae, pigments chlorophyll a, c, fucoxanthin, mannitol + laminarin stored, wall of cellulose + algin. Statement 3 → Porphyra = Rhodophyceae, pigments chlorophyll a, d, phycoerythrin, food as floridean starch, no flagella. Statement 4 → Ulothrix = Chlorophyceae, filamentous, has apical equal flagella, starch in pyrenoids, fresh water habitat. Statement 5 → Sargassum = Brown alga, fucoxanthin pigment, laminarin stored, marine habitat. Thus, all five statements are correct.
