The RER works in accord with the golgi body to send new proteins to their proper destinations. The presence of ribosomes on its surface gives it a rough appearance and hence the name. The rough endoplasmic reticulum or rough ER, is a vast interconnected membrane system located close to the nucleus. It serves as a site of protein synthesis and is therefore termed as the workhorses of protein biosynthesis.įunction: Builds and synthesizes proteins. They are small packets or granules of RNA that convert amino acids into proteins. The glyoxylate cycle, that takes place in germinating seeds, occurs in peroxisomes. They also assist in photo-respiration in leaves.įunction: Regulates the breakdown of metabolic hydrogen peroxide. They also assist the chloroplasts in photo-respiration. Membrane-bound packets of oxidative enzymes, the peroxisomes play a vital role in converting fatty acids to sugar. It is composed of proteins and nucleic acid and is known to be a genetically determined element.įunction: Produces ribosomes. Known to be the heart of the cell, the nucleolus transcribes ribosomal RNA. It is a membrane-bound structure that contains the cells hereditary information.įunction: Controls expression and transcription of the gene. The nucleus contains DNA within the chromosomes. It regulates various cell functions by controlling the protein synthesis of the plant cell. The nucleus is known to be the ‘control room’ of the cell. This is a spherical body that contains various organelles like the nucleolus (where ribosomal RNA is produced) and is surrounded by a nuclear membrane. It is responsible for regulating membrane potential, programming the death of the cell and regulating cellular metabolism.įunction: Produces energy and converts it, regulates cell metabolism. ATP stores and releases energy required for the cell to function. They are made up of cristae or finger-like structures, which convert the sugar into Adenosine Triphosphate or ATP. Known to be the ‘power house’ or the ‘storehouse of energy’ of the cell, the mitochondria plays an important role in a cell. Function: Sorts, processes and modifies proteins. It is crucial in segregating and transporting material within the cell. It is a stack of membrane-bound structures that, is involved in the transportation of lipids and modification of proteins. Known as the ‘golgi complex’ or the ‘golgi apparatus’, it is located near the nucleus. Tilly: The best thing about being a butcher, I would say for me is talking about how to cook meat, how it's raised, and seeing people choose to buy ethical and sustainable meat.Īdam: Best thing about my job is definitely eating the fruit and vegetables every day.Function: Serves as the site of multiple cell processes including cell metabolism. We use temperature and humidity to keep the fruit and vegetables fresh. But when the plant starts to lose water, we start to see the plants going wilted and droopy. When they're well-watered, the vacuoles are firm. Tilly: Once you take the bones out of the meat itself, it's very easy to tie it up and change the shape of it.Īdam: Some fruit and vegetables have really strong cells such as root vegetables, carrots, fruits like apples. This is why fruit and vegetables have a nice crunch and firmness to them. Plants feel firm because of their cellular walls. They are made up of a cell wall, cell membrane, cytoplasm, vacuole, nucleus, and chloroplasts. Meat is composed of animal cells, the cell membrane, the cytoplasm, and the nucleus.Īdam: My name is Adam, and I work for a fruit and vegetable business. I've always been fascinated with bodies, with animals, with humans, how they work, what they're made up of. I cut and sell meat over the counter to the public.īiology was probably my favourite subject funnily enough.
