Seeds, germination, and plant propagation are central to understanding how flowering plants reproduce and how growers choose suitable methods for producing new plants. This Grade 7 Science worksheet explores pollination, fertilization, seed formation, germination conditions, and vegetative propagation through scientific reading, knowledge checks, and evidence-based reasoning connected to the Alberta Plants for Food and Fibre topic.

Explore How Plants Reproduce and Grow

Students trace the flowering plant life cycle from pollen moving from an anther to a stigma through fertilization and seed development. They examine the embryo, seed coat, and stored food supply, then investigate the conditions that support germination, including water, oxygen, and suitable temperature. The reading also explains why the root usually emerges before the developing shoot and how light supports seedling growth after emergence.

Students compare seed propagation with vegetative propagation using examples such as stem cuttings and potato tubers. They also connect plant growth to environmental conditions, including rainfall, temperature, and soil drainage, while considering how fair tests and careful observations help explain differences in germination.

What Students Practise

The worksheet combines a scientific reading passage with multiple-choice questions, true-or-false statements, short-answer responses, a labeled diagram, a categorization activity, and a short-note task. These activities reinforce key plant reproduction vocabulary while asking students to explain processes and apply their knowledge to realistic growing situations.

• Trace how pollination and fertilization contribute to seed formation.
• Identify the basic conditions required for seed germination and explain the role of oxygen.
• Distinguish seed propagation from vegetative propagation and select suitable examples.
• Compare germination under different temperatures while keeping other variables consistent.
• Use scientific reasoning to explain poor germination in waterlogged soil and suggest an investigation improvement.

Included with Your Resource

• ✔️ Grade 7 Science student worksheet covering seeds, germination, and plant propagation.
• ✔️ Separate answer key PDF for checking student responses.
• ✔️ Student Notes lines at the bottom of the worksheet for recording key ideas.
• ✔️ Teacher Guide included in the answer key PDF, with Learning Objectives, Teaching Tips, Discussion Questions, and Common Mistakes.

Practical Ways to Use the Worksheet

Use this plant reproduction worksheet during a lesson on Plants for Food and Fibre, as guided reading followed by independent practice, or as a review after teaching seed structure and germination. The questions about temperature comparisons and waterlogged soil also provide opportunities to discuss controlled variables, observation records, and evidence-based explanations. The answer key supports efficient review, while the teacher guidance helps prepare discussions and address common misconceptions.

A useful addition to your Grade 7 plant science materials, this resource brings reproductive processes, propagation methods, and environmental influences together in one coherent learning sequence. Students practise recalling scientific facts, explaining cause and effect, and applying investigation skills to decisions that growers make when raising plants.
