How do seaweed reproduce?

Answer 1

== == : In the joining of specialized male and female reproductive cells, called gametes, seaweeds can reproduce sexually. The adult seaweed plant cells are diploid, which means they contain two sets of chromosomes. Diploid plants, sporophytes, poduce and release spores. Spres are produced by a cell division process (meiosis) that halves the number of chromosomes and forms two new cells each containing only one set of chromosomes (haploid cells). : After being released from the sporophyte, the haploid spres settle and grow into gametophytes. The gametophytes then produce sperm or eggs. When the sperm and egg are fused together, a diploid zygote is formes, and as the zygotes develop into diploid sporophytes, the cycle continues. : Some seaweeds also reproduce asexually, through a process that does not involve gametes. Fragmentation or division occurs when parts of the seaweed plant breaks off and can regrow directly into new plants. All seaweed plants that result from asexual reproduction are clones. Offspring and parent seaweed plants are genetically identical

How do seahorses reproduce?

Sea horse males do not become pregnat, the female seahorse produces eggs and then passes them to the male, who holds them in a pouch on his belly. Courtship can last for 12 hours, with the pair performing elaborate dances and displays. With their tails entwined, the female aligns a long tube (ovipositor) with her mate's pouch. Strings of sticky eggs move through the tube and into the male's pouch. The eggs, now called embryos, will develop for ten days to six weeks, depending upon the species and water conditions. Finally, over the course of many hours, the male pumps his tail until the baby seahorses emerge.
First the mom and the dad meet each other in the dad's territory. One day the mom deposits eggs into the dad's pouch. Then the seahorses are born from the dad.
Well, seahorses reproduce REALLY weirdly.

Answer 4

Seaweed reproduces by division. If a piece of seaweed gets torn off, it will grow into a fully functioning seaweed plant.

Answer 5

yes, once you have got it out from the root, but it takes quite some time. If you dont cut it from the root, it will shoot back fairly soon. have a good day.
