Photosynthesis and energy capture in ecosystems are the focus of this Grade 10 Science resource for a cells and systems unit. Students explore how photosynthesis captures light energy, stores it as chemical energy in carbohydrates, and supports biomass production in ecosystems.

From Light Energy to Chemical Energy

Students examine the role of chlorophyll and light-dependent reactions in producing energy-rich molecules. The resource asks learners to connect the capture of light energy with its storage as chemical energy, strengthening their understanding of photosynthesis as an important process in living systems.

Environmental influences are also addressed. Students analyze how light availability and seasonal changes can affect biomass production, giving them an opportunity to connect photosynthetic activity with changing environmental conditions.

Science Practice Through Multiple Formats

The worksheet combines multiple-choice questions, true-or-false statements, short-answer questions, a reading passage, matching, a cloze passage, an essay, and a “Did You Know?” activity. The varied tasks give students opportunities to recall concepts, explain biological processes, analyze environmental effects, and communicate scientific reasoning in written form.

Ready-to-Use Teacher Support
