Question

Ulva reproducing by quadriflagellate zoospores which has:
bol 13 Chromosomes (b) Sexual reproduction
(c) Gametophytic phased 26 Chromosomes​

Answer 1

Answer:

26 chromosomes

Explanation:

Because all of these options belong to sexual character.

Answer 2

Let me write the question correctly for you.

Question:

Ulva reproduces by producing quadri-flagellate zoospores, which have:

(a) 13 Chromosomes

(b) Sexual reproductive phase

(c) Gametophytic phase

(d) 26 Chromosomes

Answer:

Ulva reproduces by producing quadri-flagellate zoospores, which have 13 chromosomes. The correct option is (a)

Explanation:

• In Ulva (a type of marine algae), the sporophyte develops into a diploid (2N) plant that is identical to the haploid plant. Specialized cells in the sporophyte undergo meiosis to produce haploid zoospores. This is an asexual process.
• These zoospores are quadri-flagellate. The zoospores do not fuse. Instead, they divide by mitosis and form different (male and female) gametophytes.

As the zoospores are haploid, so their chromosome number will be 13.

Hence, the correct option is (a)
