What would happen if there are no cell organelles ?
Answers
Answer:
cover the basic organelles of some different cells:
Nucleus - without this, the cell would have no “command centre” or DNA . Yes, some cells don't have a nucleus, but those that do need them, or they won't survive for long. There'd be no mRNA reaching the ribosomes, and it'd have no protein to use for growth and repair.
Mitochondria - without these, a cell would be unable to respire, so it wouldn't last very long at all before it died.
Ribosomes - strictly speaking, a cell could function without these, if it had an external source of protein synthesis. However, a cell with ribosomes probably won't have this, so if they were removed it would have no source of growth and repair. Therefore, it would die.
Cell membrane - without this, a cell would just expand, and become a lifeless mass floating around. As well as the obvious implications on the cell's form, it would also harm it's ability to regulate chemicals entering it, so it would just fill up with stuff it doesn't want, and lose stuff it wanted. Let's just say it wouldn't last long.
Cell wall - obviously, many cells don't have a cell wall, but those that do have one has it for a reason - usually to keep the cell's strength and shape. If this organelle disappeared, I don't think the cell would die, but if it was, for example, a plant cell, the plant that the cells make up would lose its stature if all of its cells lost their cell wall.
Cytoplasm - if this suddenly disappeared, the innards of the cell would essentially be a vacuum, bar possibly a few resources floating such as amino acids and proteins. The cell would most likely shrivel up, like if you removed all the water from it, but to a greater extent. Everything inside it would be damaged, and then it'd have no place to carry out chemical reactions - it would probably die.
Vacuole - this stores food (cell sap, in plant cells) for the cell, and without it the cell wouldn't have enough glucose amd other resources to last through difficult seasons. Therefore, whilst the cell may well survive, it may not last through the year. As well as this, vacuoles keep the cell's shape, to some extent, and depending on the size of the vacuole, its disappearance could result in physical damage to the cell.
Chloroplasts - these contain chlorophyll, to photosynthesise. However, plant cells could probably survive without them, on an individual basis, but the plant would end up dying due to a lack of glucose if all of its cells had no chloroplasts.
Flagellum - a bacterium, for example, would certainly be able to survive without this, theoretically. However, as it requires a flagellum to move, it would struggle to get the resources it needs to survive. Therefore, it would most likely die after a short period of time. Well, if the bacterium had access to resources in its own location, when the flagellum disappeared, it could survive, but it seems unlikely.
Golgi apparatus - this organelle organises the movement of lipids and proteins throughout the cell, so without these organelles the lipids and fats would float around uselessly, meaning the cell would probably die due to a lack of protein pretty soon.
Explanation:
- Cells are the fundamental building components of all living things. Humans have trillions of cells in their bodies.
- Cells are the building blocks of plants and animals.
- The cell is made up of three parts: the cell membrane, the nucleus, and the cytoplasm that lies between the two.
- Organelles are complex groupings of tiny fibres and hundreds or thousands of extremely small yet distinct structures that exist inside the cytoplasm.
- They are specialised structures within the cell that conduct certain functions.
