A group of unicellular, photosynthetic algae that have a glassy silica cell wall consisting of two parts or shells that fit together.

What would be an accurate way to describe viruses?

The function of these prokaryotes is to transform or decompose organic matter (dead organisms) into their basic elements so that they can be reincorporated into ecosystems through biogeochemical cycles.

Some of these prokaryotes are used in the production of dairy products such as yogurt. Others have the ability to digest oil and are used in environmental remediation processes. Some others are used to synthesize medicines.

These types of prokaryotes convert atmospheric nitrogen into forms useful to other organisms. For example, they transform it into ammonia, which is then transformed into nitrates for plant uptake. It also forms part of the protein-forming amino acids in all living things.

Cyanobacteria are photosynthetic organisms and are among the most important and abundant producers on the planet. It is estimated that this group produces half of the primary production in the oceans. They're an example of...

Prokaryotes differ from Eukaryotes in that their cells…

These are characteristics of bacteria:

These are characteristics of archaea:

Which of the following statements does NOT apply to the protist group?

Temporary extension of an amoeboid cell used for feeding and locomotion.

A short hair-like structure that projects from certain cells. It is used in locomotion or movement of materials to the cell surface. They can occur in large numbers.

A long, mobile structure that projects from certain cells. It is used for locomotion. In protists they have a 9 + 2 microtubule arrangement.

To what protist group does Euglena sp. belong to?

To what protist group does Dinoflagellata belong to?

To what protist group does Radiolaria belong to?

To what protist group does Chlorophytes belong to?

To what protist group does Mycetozoa belong to?

A group of fungi whose cell wall has simple septa, most have fruiting bodies and many of them are macroscopic, such as mushrooms and cap mushrooms.

The structure that forms the body of the fungi, consisting of a network of branched and interwoven hyphae adapted for absorption, is called mycelium.

Bryophytes with horn-shaped sporangia belong to the Class Antocerothae and those with flat, liver-shaped gametophytes belong to the Class Marchantiophyta.

What are characteristics of tracheophytes not found in bryophytes?

All sporophytes are tracheophytes

Examples of sporophytes are...

Ferns and mosses are two types of flowering plants with vascular systems.

A composite organism that arises from algae or cyanobacteria living among filaments of multiple fungi species in a mutualistic relationship is known as:

Mutualistic associations between fungi and plant roots are called:

Which of the following is not a trait found in plants?

In sexually reproducing fungi, the haploid is stage is dominant over (i.e. longer than) the diploid stage.

What fungal groups produce zoospores?

The haploid stage is the dominant one in the tracheophytes' sexual cycles.
