Explanation:

A pronoun is a word that takes the place of a noun. It can refer to people, places, things, or ideas. In this task, we are identifying and underlining pronouns in each sentence. Here’s how we identified them:

1. "her" in "Amy enjoyed her birthday cake."
- "Her" replaces the name of the person (Amy) who owns the birthday cake.

2. "We, our" in "We visited our grandparents on Saturday."
- "We" refers to the group of people speaking, and "our" indicates possession by the group.

3. "us" in "Mum enjoyed playing cards with us."
- "Us" refers to the people Mum was playing cards with.

4. "his" in "Joel and his friends played rugby."
- "His" indicates possession by Joel.

5. "their" in "The cats licked their paws."
- "Their" indicates possession by the cats.

6. "their, their" in "The students were excited to share their work with their parents."
- The first "their" refers to the students' work, and the second "their" refers to the parents of the students.

7. "her" in "Michelle wore her new shirt."
- "Her" indicates possession by Michelle.

8. "her" in "The nurse treated her patient."
- "Her" indicates possession by the nurse.

9. "My" in "My family went to the zoo."
- "My" indicates possession by the speaker.

10. "their" in "The sisters helped their mum."
- "Their" indicates possession by the sisters.

By carefully analyzing each sentence, we can identify the pronouns and underline them as required.
