Grana thylakoids and stroma thylakoids can be distinguished by their different protein composition. Grana contribute to chloroplasts' large surface area to volume ratio. A recent electron tomography study of the thylakoid membranes has shown that the stroma lamellae are organized in wide sheets perpendicular to the grana stack axis and form ...
This membrane is composed of a phospholipid inner membrane, a phospholipid outer membrane, and an intermembrane space. Enclosed by the membrane is an aqueous fluid called the stroma. Embedded within the stroma are stacks of thylakoids (grana), which are the site of photosynthesis. The thylakoids appear as flattened disks.
Additionally, a recent study found a negative correlation between alcohol and life expectancy, citing that even just one drink per day can shorten your life by 2.5 months.
By 2050, global life expectancy, which was 72.6 years in 2019, is expected to increase by approximately five years. [166] Maintaining good nutritional status and adequate nutrient intake is essential for health, quality of life, and overall well-being in older age, and it plays a crucial role in healthy aging as defined by the WHO.

Rich in fiber, vitamins and minerals, such as magnesium, copper and manganese, nuts provide another great plant-based protein source. Eating walnuts, in particular, can help reduce blood pressure ...
Various foods. This is a categorically organized list of foods. Food is any substance consumed to provide nutritional support for the body. [1] It is produced either by plants, animals, or fungi, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, and minerals.
Chloroplasts, containing thylakoids, visible in the cells of Rosulabryum capillare, a type of moss. A chloroplast (/ ˈ k l ɔːr ə ˌ p l æ s t,-p l ɑː s t /) [1] [2] is a type of organelle known as a plastid that conducts photosynthesis mostly in plant and algal cells.
