What feature was not present in the first eukaryotes?
Mitochondria, which are thought to have originated from bacterial endosymbionts, were not present in the first eukaryotes. These early eukaryotes were likely single-celled organisms that lacked many of the organelles found in modern eukaryotic cells.
Two principal organelles of eukaryotes that share features with one another and with bacteria from which they apparently were derived are the?
Two principal organelles of eukaryotes that share features with one another and with bacteria are the mitochondria and chloroplasts. Both organelles have their own DNA and ribosomes, similar to bacteria, and are thought to have originated from ancient endosymbiotic bacteria that were engulfed by early eukaryotic cells.
Are organelles only found in eukaryotic cells?
Yes. Prokaryotes are much too small to carry chloroplasts. It is theorized that chloroplasts were once prokaryotes that started a symbiotic relations with early eukaryotic cells, which explains why chloroplasts and mitochondria are found in the eukaryotic cell.
What does archaezoa means?
Archaezoa is a proposed group of early branching single-celled organisms believed to be the most ancient eukaryotes, lacking mitochondria. They are thought to have characteristics that are similar to both prokaryotes and eukaryotes, making them a subject of interest in the study of early evolution.
How did early eukaryotes use endosymbiosis to survive?
Well, honey, early eukaryotes were like, "Hey, I need some help here!" So, they decided to cozy up to some prokaryotes and formed a little partnership called endosymbiosis. The prokaryotes brought their A-game with energy production, and the eukaryotes were like, "Thanks, now we can thrive and evolve into the fabulous creatures we are today." And that's how they rolled and survived, darling.
Why did prokaryotes evolve before eukaryotes?
Prokaryotes evolved before eukaryotes because they are simpler in structure and function, making them better suited for surviving in early Earth's harsh conditions. Their ability to adapt quickly to changing environments allowed them to thrive and evolve first.
What did Lynn Margulis account for the presence of DNA in Chromatin and Chromosomes?
Lynn Margulis proposed the endosymbiotic theory to explain the presence of DNA in chromatin and chromosomes. This theory suggests that eukaryotic cells, which contain DNA in their mitochondria and chloroplasts, arose from symbiotic relationships between ancient prokaryotic cells.
