- Grana, or singular 'granum,' are stacks of thylakoids within chloroplasts. The thylakoids contain numerous integral and peripheral membrane proteins as well as chemicals important to photosynthesis.n this lesson, we'll explore the parts of the chloroplast, such as the thylakoids and stroma, that make a chloroplast the perfect place for conducting photosynthesis in plant cells.

Thymus The thymus is a specialized primary lymphoid organ of the immune system. Within the thymus, T cells or T lymphocytes mature. T cells are critical to the adaptive immune system, where the body adapts specifically to foreign invaders.The thymus is composed of two identical lobes and is located anatomically in the anterior superior mediastinum, in front of the heart and behind the sternum.he cortex and medulla play different roles in the development of T-cells. Cells in the thymus can be divided into thymic stromal cells and cells of hematopoietic origin (derived from bone marrow resident hematopoietic stem cells). Developing T-cells are referred to as thymocytes and are of hematopoietic origin.

Thylakoid A thylakoid is a membrane-bound compartment inside chloroplasts and cyanobacteria. They are the site of the light-dependent reactions of photosynthesis. Thylakoids consist of a thylakoid membrane surrounding a thylakoid lumen.Chloroplast thylakoids frequently form stacks of disks referred to as grana (singular: granum). granum (plural grana) is a stack of thylakoid discs. Chloroplasts can have from 10 to 100 grana. Grana are connected by stroma thylakoids, also called intergrana thylakoids or lamellae. Grana thylakoids and stroma thylakoids can be distinguished by their different protein composition.

Chloroplasts and Mitochondria Name: Period: Date: Topic 3: Cell Structures Chloroplasts are double membrane organelles with a smooth outer membrane and an inner membrane folded into disc-shaped sacs called thylakoids. Thylakoids, containing chlorophyll and other accessory pigments (red, orange, yellow, brown), are in stacks called granum (grana, plural).

Thylakoid Thylakoids consist of a thylakoid membrane surrounding a thylakoid lumen. Chloroplast thylakoids frequently form stacks of disks referred to as grana[singular granum]. The thylakoid membranes of higher plants are composed primarily of phospholipids and galactolipids that are asymmetrically arranged along and across the membranes. The thylakoid lumen is a continuous aqueous phase enclosed by the thylakoid membrane. Thylakoid formation requires light. An underexposure to light can cause the thylakoids to fail.

- Grana are stacks of thylakoids that lie in the stroma (fluid filled space in the chloroplasts). It is where the light reactions of photosynthesis takes place (light and water … makes oxygen). After these light reactions in the grana/thylakoids, there are the dark reactions which take outside of the grana, in the stroma.

Thylakoid The thylakoid lumen is a continuous aqueous phase enclosed by the thylakoid membrane. It plays an important role for photophosphorylation during photosynthesis. During the light-dependent reaction, protons are pumped across the thylakoid membrane into the lumen making it acidic down to pH 4.

Plastid The plastid (Greek: πλαστός; plastós: formed, molded – plural plastids) is a major double-membrane organelle[1] found in the cells of plants, algae, and some other eukaryotic organisms. Plastids are the site of manufacture and storage of important chemical compounds used by the cell.

Thylakoid Membrane in Photosynthesis: Definition, Function & Structure Definition and Function of Thylakoid Membrane. The thylakoids themselves contain the chlorophyll, but the thylakoid membrane, which is the layer that surrounds the thylakoid, is where the light reactions take place. Embedded in the thylakoid membrane are two photosystems, named photosystem I and photosystem II.

Chloroplasts - Show Me the Green Chlorophyll molecules sit on the surface of each thylakoid and capture light energy from the Sun. As energy rich molecules are created by the light-dependent reactions, they move to the stroma where carbon (C) can be fixed and sugars are synthesized. The stacks of thylakoid sacs are connected by stroma lamellae.
