What is true of archegonia They are the sites where male gametes are produced. They may temporarily contain embryos. They are the same as sporangia. They are asex?
they are the same as sporangia.
Who produce gamete less often?
Gametes are produced less often in organisms that have longer reproductive cycles or those that reproduce infrequently. For example, larger mammals, such as elephants and whales, typically produce gametes less often due to their long gestation periods and extended intervals between breeding. Additionally, some species with complex life cycles or specific environmental triggers may also produce gametes less frequently. In contrast, smaller organisms like many fish and amphibians often produce gametes more regularly.
When do organisms complete meiosis?
Meiosis is the process of making gametes (sex cells), so depending on what you mean by your question, either of the following may be correct: 1.) Meiosis will be complete after the individual no longer makes gametes. In humans, females complete meiosis even before they are born because they create all the eggs they will ever have during gestation. In males, this is an ongoing process. 2.) Meiosis may also be considered complete after the products are finished. In humans, females produce 1 egg and 3 polar bodies. In males, 4 sperm are produced.
Do diatoms have flagella?
All mature diatoms lack flagella, but their gametes may be either amoeboid or flagellated.
What happens if the gametes aren't haploid?
The whole purpose of reducing the gamete to contain half the number of normal chromosomes is so that normal chromosome numbers can be achieved again when the gametes fuse to form a zygote. If the gamete is not halved, polyploidy results. This is a generic term to describe having more than the normal number of chromosomes.
Do males produce gametes faster then females do?
In mammals a female is born with all of the oogonium (eventually eggs) she will ever produce. However, males can continuously produce gametes throughout their lifetime. Sperm are produced in around 64 days. Primary follicles (that produce ovum) take around 20 weeks to develop.
How is spore formation different than the other type of sexual reproduction?
Spore formation is a form of asexual reproduction where specialized cells called spores are produced and dispersed to grow into new organisms. In contrast, sexual reproduction involves the fusion of gametes from two parents to create genetically diverse offspring. Spore formation does not involve the fusion of gametes and relies on a single parent organism.

Why do organisms need to produce gametes for sexual reproduction?
One might be tempted to claim that this has to do with halving the number of chromosomes, but this is false. Firstly, (in a hypothetical universe) two gametes with just as many chromosomes could fertilize and then the zygote could destroy half of its chromosomes. Secondly, we already observe in most plants that fully developed adult plants are in fact haploid and do not use meiosis but rather mitosis to produce their gametes.The simple reason is, well, logistics. There's no other way for two organisms to fuse parts of themselves to create a third organism. Gametes may or may not detach from the parents, as many fungi do. Gametes may or may not be haploid. Gametes are various, and all it really means is a cell from a parent that fuses with a cell of the opposite type. It's like opening a closed door before attempting to walk through the doorway- there really is no other logical way. It's not a question of biology or science but of logistics.

What is a gamete having more than one complete set of chromosomes?
A gamete with more than one complete set of chromosomes is called a polyploid gamete. This may occur due to errors in cell division, resulting in an extra set of chromosomes. Polyploid gametes often lead to genetic abnormalities in offspring if fertilized.
