Work out the odds - Worksheet - Year 5

The worksheet for Year 5 students explores the intricate stages of pollination and the fertilization process within plant reproduction. It begins by describing the life cycle of a plant, starting from the moment a seed germinates, through to the visitation of bees or butterflies that facilitate pollination, and finally to seed dispersal and the development of new plants. The stages are listed in a non-sequential order, A through F, including events such as the growth of the plant, flowering, and the eventual death of the flower leading to seed pod development. Some plants, such as blackberries, are noted for surrounding the seed with fruit.

The fertilization process is broken down into four key steps. It starts with the landing of pollen on the stigma (B), followed by the pollen travelling down the style to reach the ovary (D). Once inside the ovary, fertilization occurs as the pollen fertilises the ovules (A), leading to the swelling of the ovary as the seeds ripen (C). Students are tasked with reading the provided sentences and determining the correct sequence of these events, recording their answers in the designated boxes. Additionally, the worksheet prompts students to draw parallels between the life cycles of humans and animals, and to reflect on the similarities and differences with the plant reproduction process. This activity not only enhances their understanding of biological cycles but also encourages critical thinking and comprehension skills.
