My Favourite Living Thing
My favourite living thing is a sunflower. It starts from a small seed. It needs sunlight, water and air to grow. First, it grows roots and a stem. Then it grows leaves and a big yellow flower. The flower changes day by day, but it always faces the sun. Sunflowers cannot move by themselves, but they can turn towards the sun. I think sunflowers are beautiful and amazing!
