The stack of thylakoids
WebThylakoids contain chlorophyll and other pigments (red, orange, yellow, brown) and are found in stacks called granum (grana, plural.) Color and label the thylakoids dark green , then highlight the entire stack of granum with yellow . These stacks are connected to other stacks by channels called lamellae. Color and label the lamella orange. WebJun 30, 2024 · Thylakoids are membrane-bound structures embedded in the chloroplast stroma. A stack of thylakoids is called a granum and resembles a stack of coins. The thylakoid membrane is the site of the light-dependent reactions of photosynthesis with the photosynthetic pigments embedded directly in the membrane.

Plants use chloroplasts to photosynthesis, an organelle in the plant. Grana lamellae, which form the structure of these organelles, are made up of a stack of chromosomes. The thylakoid membrane surrounds a central aqueous region known as the thylakoid lumen.
WebConcept note-2: -Final answer: The stack of thylakoids of chloroplast is called a granum. Concept note-3: -Each granum is made up of a stack of closed compartment called thylakoids. Each thylakoid consists of two parallel membranes joined at their margins. The membranes of thylakoids contain the layer of particles called chlorophyll.
