Question

Чем споры мхов отличаются от гамет? Нужно не менее двух различий :) Заранее спасибо!

Answer 1

Гаметы-мужские и женские половые клетки, принимающие участие в процессе оплодотворения. Они имеют гаплоидный (одинарный) набор хромосом и обеспечивают передачу наследственной информации. Яйцеклетка содержит большой запас питательных веществ. Возникают путём мейоза. В ОСНОВНОМ КЛЕТКИ ЖИВОТНЫХ И РАСТЕНИЙ. Споры-репрродуктивные клетки грибов и низших растений, служат для размножения и расселения. Диплоидны ( двойной набор хромосом) , возникают путём митоза в спец. органах-спорангиях, зап. пит. веществ не имеют. Покрыты плотной оболочкой, устойчивой к внеш. воздействиям.

Differences between mosses and gametes

Mosses and gametes are both important components of the plant life cycle, but they have several key differences. Here are two main differences between mosses and gametes:

1. Structure and Function: - Mosses are a type of non-vascular plant that belong to the division Bryophyta. They have a simple structure and lack specialized tissues for conducting water and nutrients. Mosses typically have a leafy or cushion-like appearance and reproduce through spores. - Gametes, on the other hand, are reproductive cells that are produced by both plants and animals. They are specialized cells involved in sexual reproduction and are responsible for fertilization. In plants, gametes are produced within specialized structures called gametangia, which can be male (antheridia) or female (archegonia).

2. Reproductive Process: - Mosses reproduce through a process called alternation of generations, which involves the alternation between a haploid (gametophyte) and diploid (sporophyte) generation. The gametophyte generation produces gametes through mitosis, and fertilization occurs when the male gametes (sperm) swim to the female gametes (eggs) within the archegonia. After fertilization, the diploid sporophyte generation develops and produces spores through meiosis, which are then dispersed to grow into new gametophytes. - Gametes, on the other hand, are involved in sexual reproduction in both plants and animals. In plants, the male gametes (sperm) are typically transported to the female gametes (eggs) through various mechanisms such as wind, water, or pollinators. Fertilization occurs when the sperm fuses with the egg, resulting in the formation of a zygote. The zygote then develops into a new individual.

These are just two main differences between mosses and gametes. Mosses are a type of plant, while gametes are reproductive cells involved in sexual reproduction. Mosses have a complex life cycle involving alternation of generations, while gametes are involved in the fertilization process.
