Question

Пожалуйста, помогите. Почему цинабоктерии раньше относили к растениям???

Answer 1

Включают одноклеточные и многоклеточные формы, образующие трихомы. Основанием для отнесения синезелёных водорослей к бактериям послужили сходство в организации их клеток с клетками др. бактерий (прокариотный тип), присутствие общих специфич. соединений (напр., муреина в клеточной стенке) и близость их генетич. свойств. С др. стороны, Ц. подобно высш. растениям и водорослям осуществляют фотосинтез с выделением мол. кислорода. Многие фиксируют мол. азот. Согласно совр. классификации, образуют класс (Oxyphotobacteria). Назв. Ц. широко применяется в микробиол. лит-ре, тогда как в ботанической чаще сохраняется назв. синезелёные водоросли.

Why Were Cyanobacteria Previously Classified as Plants?

Cyanobacteria were previously classified as plants due to several reasons:

Similarities to Plants: Cyanobacteria, also known as blue-green algae, were initially classified as plants due to their superficial resemblance to plants. They are photosynthetic organisms that contain chlorophyll and produce oxygen as a byproduct of photosynthesis.

Historical Classification: Historically, the classification of organisms was based on observable characteristics, and cyanobacteria were initially grouped with plants due to their ability to perform photosynthesis and their appearance under a microscope.

Taxonomical Changes: Over time, advancements in scientific understanding and taxonomical classification led to the reclassification of cyanobacteria into their own distinct group. They are now classified as a type of bacteria, specifically a phylum of bacteria known as Cyanobacteria or Cyanophyta.

Modern Understanding: Modern molecular and genetic studies have provided further insights into the evolutionary relationships and genetic differences between cyanobacteria and plants, leading to their reclassification as bacteria rather than plants.

In summary, cyanobacteria were previously classified as plants due to their superficial similarities and historical classification methods. However, advancements in scientific understanding and taxonomical classification have led to their reclassification as a distinct group of bacteria.
