UP Board Class 11 Biology – Photosynthesis in Higher Plants
The chapter “Photosynthesis in Higher Plants” in UP Board Class 11 Biology explores the process by which plants convert light energy into chemical energy to produce organic compounds. It explains the significance of photosynthesis in sustaining life on Earth and maintaining the oxygen and carbon cycles.
Students learn about the site of photosynthesis (chloroplasts), pigments involved (chlorophyll a, b, and accessory pigments), and the light-dependent (photochemical) and light-independent (Calvin cycle) reactions. The chapter also covers factors affecting photosynthesis, such as light intensity, carbon dioxide concentration, and temperature.
The process of photosynthesis is discussed in detail with emphasis on photophosphorylation, electron transport, and carbon fixation pathways (C?, C?, and CAM plants). Understanding photosynthesis is fundamental for studying plant physiology, ecology, and energy cycles. This chapter lays the foundation for higher studies in botany and competitive exams like NEET and CUET.
