Consider From Seed to Plant by Gail Gibbons.

“Bright, picture-driven, and firmly aimed at early elementary listeners, this book walks through pollination, seed formation, and germination in clear, child-accessible steps. The strongest value is the combination of simple, age-appropriate vocabulary and colorful diagrams that make basic plant processes memorable during a single read-aloud. Its main limitation is scope: adults or older kids seeking depth or experimental instructions will find the text spare and the explanations high-level rather than detailed. No hands-on exercises are provided.”
