Plastids/Chloroplasts Plastids or chloroplasts are specialized organelles, found in plants and some algae, which contain important functions that include photosynthesis, pigment storage, and macromolecule synthesis. For students of MDCAT, a good understanding of the structure and function of plastids, more specifically chloroplasts, can help them provide answers to most questions on the topic of plant biology, cellular metabolism, and biochemistry in MDCAT Quiz. Chloroplasts are actually a type of plastid, very important for transforming solar energy into chemical energy through glucose during the process of photosynthesis. In the following post, we will identify the key characteristics of plastids, their function in cellular processes, and significance for MDCAT preparation. Chloroplast contains the pigment called chlorophyll, which is responsible for light energy capture that drives the process of photosynthesis. H2: Structure and Function of Plastids H3: MDCAT Quiz on Plastids/Chloroplasts The chloroplast has a double membrane structure in which the inner membrane is made up of thylakoids that contain the pigment chlorophyll. Thylakoids are stacked to form structures that are called grana, involved in the process of light-dependent reactions of photosynthesis. The fluid space surrounding the thylakoid is called the stroma. It is there that the process of the Calvin cycle takes place, converting carbon dioxide and water into glucose. Chloroplasts are very vital for plants and some algae. They allow plants and some algae to produce food by photosynthesis, a process that also creates oxygen as its byproduct. MDCAT students need to understand the various stages of the process of photosynthesis, like the light reaction and the Calvin cycle. For, these processes come up frequently during the MDCAT Quiz. H3: Free Flashcard on Plastids/Chloroplasts To help strengthen your knowledge on plastids and chloroplasts, using Free Flashcard for MDCAT students is very helpful. For, flashcards can help to review the fundamental concepts such as the structure of chloroplast, the process of photosynthesis, and the function of thylakoids and stroma during energy production. Regular use of these flashcards will help in retaining the right information and in gaining confidence when sitting for MDCAT Quiz. Understanding how the chloroplast operates within the cells of plants, to produce energy, will further help you handle questions on topics related to the metabolism of plant,.
