Sexual reproduction is of isogamous, anisogamous and oogamous in
1 Phaeophyceae and Rhodophyceae
2 Rhodophyceae
3 Chlorophyceae and Phaeophyceae
4 Chlorophyceae and Rhodophyceae
Explanation:
In Chlorophyceae and Phaeophyceae, the sexual reproduction shows considerable variation in the type and formation of sex cells and it may be isogamous, anisogamous or oogamous. Whereas, in Rhodophyceae, only oogamous mode of reproduction is seen.

Assertion : Chlorella a green algae is commonly known as space alga. Reason : It is used by exobiologists for oxygen and disposal of nitrogen in prolonged space flight.
1 Both Assertion and Reason are true and Reason is correct explanation of Assertion.
2 Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
3 Assertion is true but Reason is false.
4 Both Assertion and Reason are false.

The members of Chlorophyceae, phaeophyceae and rhodophyceae have a common pigment, identify it from the below option
1 chlorophyll-a
2 chlorophyll-b
3 chlorophyll-a and b
4 chlorophyll-c
Explanation:
Chlorophyll-a, also known as the universal pigment is present in all plants. It is hence a common pigment in Chlorophyceae, Phaeophyceae and Rhodophyceae.

Statement A : Asexual reproduction is by flagellated zoosporangia in chlorophyceae. Statement B : All chlorophyceae species show haplo-diplontic life cycle.
1 Statement A is correct but statement B is incorrect.
2 Statement A is incorrect but statement B is correct.
3 Both statements are correct.
4 Both statements are incorrect.
Explanation:
Zoospores are flagellated and not zoosporangia. Chlorophyceae generally shows haplontic life cycle.

Identify the different types of chloroplasts in Chlorophyceae?
1 Discoid and plate-like
2 Reticulate and cup-shaped
3 Spiral or ribbon-shaped
4 All of them
Explanation:
The pigments in green algae are localized in definite chloroplasts. The chloroplasts may be discoid, plate-like, reticulate, cup-shaped, spiral or ribbon-shaped in different species.
