BIOLOGI Kelas 11 - Sejarah Penemuan & Komponen Penyusun Sel | GIA Academy

Hello everyone, welcome back to Gia Academy Youtube Channel. I hope you are always excited and don't forget to take care of your health. Oh yes, friends, now there are many technologies in dealing with health problems. One of them is the following technology.

This technology is one of the latest medical technology that can help scientists detect cancer-prone tumor networks. Wow, cool, right? So, scientists no longer need to send samples for testing in pathology laboratories.

Well, guys, the technology was named as Mesh Pack Pen, which function is to detect cancer cells. Actually, cancer cells are from the body's network cells that split abnormally, so it's dangerous for other cells. So, what are cells? Let's find out in this video. Don't forget to watch until the end.

Do you know the history of cell discovery and development? Well, there are several experts who are known in cell discovery. There are Robert Hooke, Robert Brown, Matthias Jacobs Clayden and Theodor Sjahwan, Rudolf Virchow, Felix Dürjadin, and Max Kjuls.

Robert Hooke, he is the first person to reveal about the cell. He observed the spider web and found the small space called cell. So this spider cell is an empty dead cell without any contents. The second expert is Robert Brown, who stated that the cell is a small space limited by a membrane that contains liquid or protoplasm.

Next, there are Matthias Jacob Skleiden and Theodor Sahwan. They observed different cells. Skleiden observed the growth cell, while Sahwan observed the animal cell. They stated that the living creature's body is organized on small units called cells. And they concluded that cells are the structural units of living creatures. Well, friends, it means that we have discussed three experts.

The fourth expert is Rudolf Virchow. He stated that the cell is from the previous cell known as the Omnicellular X Cell. Next, Felix Dürjadin. He stated that the most important part of the cell is the cell fluid. This cell fluid is named protoplasma by Johannes Purkinje.

The last expert is Max Schultz, who stated that cells are functional units of living beings based on the presence of protoplasmas as the basis of physical life. So, in this cytoplasm, various processes are carried out that are based on the life of living beings. Amazing, huh? The results of the findings of the experts, they summarized the development of cells from dead cells to cells that are based on our lives.

So, we can conclude that cells are the smallest unit of living things that can perform the life process, even though the size is very small but the role is very large. Then, what are these cells arranged on? Chemical components that arrange cells. There are elements and particles.

Well, the elements that arrange the cells are divided into two. First, the macro element, which means the element found in a large number in the cell. Second, there is the micro element, which means the element found in a small number in the cell.

Next, we will discuss the substance of cell arrangement. Substances are also divided into two types. First, organic substance. Second, there is an organic substance. Let's discuss one by one. Organic substance

The first organic substance is carbohydrates. Carbohydrates are arranged on carbon, hydrogen, and oxygen atoms. Carbohydrates are energy sources and important components for the cell wall. Carbohydrates in the cell membrane are oligosaccharides and polysaccharides, which can be bound with proteins and lipids to form glycoproteins and glycolipids.

Carbohydrates also function as a material for the cell respiration process.

The next organic substance is protein, which is the largest organic element that organizes a cell. Protein is organized on amino acids and several elements. Proteins that organize cells can be distinguished into two types. There is a structural protein that plays a role in the formation of cell structures, and there is a functional protein that plays a role in the regulation of cell activity, such as enzymes and hormones.

The last organic substance is the lima or lipid, which is arranged on carbon, hydrogen, and oxygen. There are many important lipids in the cell, including phospholipids, glycolipids, and steroids. But the most common in the cell is phospholipids. Lipids have several functions.

namely helping to mix plasma with protein and carbohydrates and as a backup energy source for cells. How? So far you can understand, right? Well, if we have discussed the organic part, now we continue to the unorganic substance.

Water is the main component in protoplasm, the number reaches 50-95%. The function of water, among other things, is as a direct media for chemical reactions in the cell and as a hydrolysis material in the transportation of substances.

The second is Mineral Salt, which undergoes ionization in the protoplasm to form ions such as cation and anion. These ions function to maintain osmotic pressure and balance of liquid acid in the cell. Mineral salt examples are: NaCl, MaCl, CaS, CaDH, PhO2, and NaB.

Next, gas. Gas that is involved in cell activity is oxygen, carbon dioxide, and ammonia. They have their own role. Oxygen is needed for cell respiration. Carbon dioxide is the side effect of cell respiration and cell fermentation. For plants, it is used for photosynthesis.

while ammonia gas is the residual product of protein discharges. How? Have you understood about the cell and its arrangement? To understand more, let's finish the following questions. The first question is about the history of cell discovery. The cell is a small space limited by a membrane and inside it there is liquid. What do you think this theory is? Please answer first.

Thank you.

Let's discuss one by one. Robert Hooke observes dead cells that do not have protoplasm. Robert Brown observes living cells that have protoplasm. Rudolf Virchow argued that cells are derived from previous cells. Felix Durjadin said the most important part of the cell is the fluid of the cell. Meanwhile, according to Max Kohl's, cells are functional units of living beings.

So the correct answer is B, this is the Robert Brown theory. The second question is about the function of the chemical components that organize the cells. Well, what about the function of salt and mineral? Please answer first.

Let's discuss! The chemical reaction media of the cell is the function of water. The main material in photosynthesis is carbon dioxide, which is one of the gas-like inorganic substances. The main material in the cell respiration is oxygen, which is also an inorganic substance of gas.

Maintaining the balance of acid-water in the cell is a function of salt-mineral salt. The cell activity regulation is a function of functional protein. So the answer is D, the function of mineral salt to maintain the balance of acid-water in the cell.

Well, what have we discussed in this video? From the beginning, we already know how the history of cell discovery according to experts. Then we also know about cells. Remember, cells are the smallest units that carry out the life process. And finally, we have also learned what the components are.

what is the order of the cells there are elements of macro and micro also there are organic and inorganic cells until here friends understand ya Okay friends don't forget to watch videos on our channel see you in the next video
