I'm studying for a test and can't find the answers for the following questions...please help!

What clade of bacteria produce oxygen via photosynthesis?

What is a synapomorphy for domain Bacteria?

In a symbiotic relationship between organisms of significantly different sizes, the larger
organism is called the ___________, and the smaller organism is called the
___________________.

Thanks!

I think the synapomorphy is the presence of a nucleus.

Of course, I'd be happy to help you find the answers to your questions!

1. What clade of bacteria produce oxygen via photosynthesis?
To find the answer to this question, you can start by researching different groups or clades of bacteria that are known for their ability to produce oxygen via photosynthesis. One such clade is called Cyanobacteria. Cyanobacteria are photosynthetic bacteria that use sunlight to produce energy and oxygen as a byproduct. They are commonly found in various aquatic environments and are often referred to as blue-green algae.

2. What is a synapomorphy for domain Bacteria?
A synapomorphy is a shared derived trait that defines a particular group or taxonomic category, in this case, the domain Bacteria. To determine a synapomorphy for domain Bacteria, you will need to identify a trait that is unique to or characteristic of all bacteria.

One such synapomorphy for domain Bacteria is the presence of peptidoglycan in their cell walls. Peptidoglycan is a polymer that provides structural support and protection to bacterial cells. This trait distinguishes bacteria from other domains, such as Archaea and Eukarya, as they have different cell wall compositions.

3. In a symbiotic relationship between organisms of significantly different sizes, the larger organism is called the _________, and the smaller organism is called the ___________.
To find the terms that describe the larger and smaller organisms in a symbiotic relationship, it's important to understand the concept of symbiosis. Symbiosis refers to a close and long-term biological interaction between two different species.

In cases where the organisms involved in the symbiotic relationship are of significantly different sizes, the larger organism is typically referred to as the host, while the smaller organism is often called the symbiont. The host provides resources and a suitable environment for the symbiont, while the symbiont offers some form of benefit, such as protection or nutrient exchange.

So, to answer your question directly, the larger organism is called the host, and the smaller organism is called the symbiont in a symbiotic relationship between organisms of significantly different sizes.

I hope this helps you with your studies! Let me know if there's anything else I can assist you with. Good luck with your test!
