Chapter 13 Section 1- Photosynthesis Photosynthesis process by which plants make their own food. Capturing Light Energy Plant cells have organelles called chloroplasts. Chloroplasts are surrounded by two membranes. Inside stacks of membranes are called grana . Grana ( granum sing. ) is where chlorophyll is found. Formula for photosynthesis 6CO 2 +6H 2 O light energy C 6 H 12 O 6 +6O 2 Getting Energy from Sugar Glucose molecules store energy. Plants cells use this energy for life processes. To get energy, plant cells break down glucose in a process called cellular respiration . C 6 H 12 O 6 +6O 2 6CO 2 + 6H 2 O Gas Exchange

Unformatted text preview: Leaves contain waxy substance called a cuticle . The cuticle protects the plant from water loss. Carbon dioxide enters the leaf through the stomata (stoma), an opening. Each stomata is surrounded by two guard cells , which opens and closes the stoma. 1 When stomata are open, carbon dioxide enters the leaf. The oxygen produced during photosynthesis exits the leaf through the stomata. The loss of water from leaves is called transpiration. When more water is lost form a leaf than absorbed through a plants root, the plant wilts. 2...
