a 15. Although the leaves of a pitcher plant,a Venus flytrap, and a cactus do not appear to be very similar, they are derived from a structure present In a common ancestor This is an example of Analogous structures Vestigial structures Rudimentary structures Homologous structures

## Step 1<br />The problem is asking us to identify the type of structure that the leaves of a pitcher plant, a Venus flytrap, and a cactus represent. The options provided are analogous structures, vestigial structures, rudimentary structures, and homologous structures.<br /><br />## Step 2<br />Let's define each of these terms:<br />### Analogous structures are those that perform a similar function but are not derived from a common ancestor.<br />### Vestigial structures are remnants of structures that had a function in an ancestral species but are no longer functional in the current species.<br />### Rudimentary structures are basic or undeveloped structures.<br />### Homologous structures are those that are derived from a common ancestor, even though they may perform different functions.<br /><br />## Step 3<br />Given the definitions, the leaves of a pitcher plant, a Venus flytrap, and a cactus are derived from a common ancestor, even though they perform different functions. This makes them homologous structures.
