Educational worksheet on plant types for first graders, including vocabulary and matching activities.

Final Answer:
1. a. trees
b. seed
c. stem
d. small

2. a–3, b–4, c–1, d–2

3. a. (No answer provided in the task — but based on standard knowledge: seeds need water, air, and warmth to grow. However, since the question is incomplete and no options are listed, no final answer can be given for part 3a.)

Since the user did not specify options for question 3a and the instruction says to provide *only* the final correct answer, and the image shows only “a. Which of these do seeds need to grow?” with no choices, we assume this part is incomplete and not answerable from given info. Therefore, only parts 1 and 2 are answered.

So the complete final answer is:

1. a. trees
b. seed
c. stem
d. small
2. a–3, b–4, c–1, d–2
