They are called thylakoids.
The internal membranes found in chloroplasts are called thylakoid membranes. Thylakoid membranes house the pigments and proteins necessary for the light-dependent reactions of photosynthesis. These membranes are arranged in stacks called grana.
They are called grana.Light reaction takes place there.
Chloroplast is an organelle found in plants and algae cells where photosynthesis occurs. The chloroplast contains chlorophyll which is the light sensitive pigment that powers photosynthesis and other pigments. Chlorophyll gives the plant its green color A plastid containing chlorophyll, developed only in cells exposed to the light. Chloroplasts are minute flattened granules, usually occurring in great numbers in the cytoplasm near the cell wall, and consist of a colorless ground substance saturated with chlorophyll pigments. Under light of varying intensity they exhibit phototactic movements. In animals chloroplasts occur only in certain low forms. Chloroplasts are what give plants their green color. Organelle that makes sugars, using carbon dioxide, water, and the energy from sunlight. Cholorplasts can be found in plant cells and produces food. It is an eukariyotic organelle. It is important for photosynthesis
You can use a saclike membrane-bound organelle called a vacuole to store water, nutrients, waste products, and other substances in plant and fungal cells. The vacuole helps maintain turgor pressure, store important molecules, and also serve as a site for degrading waste materials.
This is straight from www.thefreedictionary.com, so I get no credit at all:"Any of various invertebrate animals of the phylum Cnidaria, characterized by a radially symmetrical body with a saclike internal cavity, and including the jellyfishes, hydras, sea anemones, and corals. Also called coelenterate."
The internal membranes found in chloroplasts are called thylakoid membranes. Thylakoid membranes house the pigments and proteins necessary for the light-dependent reactions of photosynthesis. These membranes are arranged in stacks called grana.
They are called grana.Light reaction takes place there.
The light-independent reactions of photosynthesis, or the Calvin cycle, take place in the stroma of the chloroplasts. This is where carbon dioxide is converted into glucose using the ATP and NADPH produced during the light-dependent reactions.
