1108 Module 1 Review

Front

What is a common trait of fungi?

Back

Fungi are heterotrophic organisms that reproduce asexually and have a mycelium composed of hyphae.

Front

Which life cycle events involve changes in ploidy for eukaryotic organisms?

Back

Changes in ploidy occur during meiosis and fertilization.

Front

What does parsimony mean in the context of phylogenetic trees?

Back

Parsimony refers to the principle that the tree topology is based on the fewest changes possible.

Front

What is the main difference between protostomes and deuterostomes?

Back

Deuterostomes develop the anus first, then the mouth, while protostomes develop the mouth first.

Front

What are phylogenetic trees?

Back

Phylogenetic trees are hypotheses representing relatedness that change as new evidence is found.

Front

What types of data are used to construct phylogenetic trees?

Back

Morphological data (such as organs) and genetic data (such as ribosomal RNA) are used.

Front

What is heterotrophy?

Back

Heterotrophy is the mode of nutrition where organisms obtain their food by consuming other organisms.

Front

Define mycelium in fungi.

Back

Mycelium is the network of hyphae that forms the vegetative part of a fungus.

Front

What is the significance of the outgroup in phylogenetic analysis?

Back

An outgroup is used to help determine the evolutionary relationships among the ingroup species.

Front

What is the role of homology in constructing phylogenetic trees?

Back

Homology refers to traits inherited from a common ancestor, which are used to infer evolutionary relationships.
