Cell excretion is the process by which a cell gets rid of waste and toxins through its cell membrane. The main parts involved are the vacuoles, which are small pockets that store waste, and lysosomes, which break down larger waste molecules. Approximately 600 million years ago, cells began using vacuoles to dispose of waste near the cell membrane, which would then encapsulate the waste and expel it from the cell. This process protects the cytoplasm and prevents foreign substances from entering.

4. …What Is Cell Excretion…Cell Excretion is the process in which a cell gets rid of the wastes, and toxins that could be damaging it, by its cell membrane.

5. …Process…Shortly after the eukaryotic cell vacuoles started doing to help them catch their food and store, about 600 million years, cells also started to use the vacuoles to dispose of garbage in the cell - the cell molecules no longer needed .If the cell uses photosynthesis, this would mainly extra oxygen, and if not, most of the trash will be additional carbon dioxide.

6. Cell got rid of the trash to bring the garbage near the cell membrane and then close the cell membrane around the waste, isolating it from the rest of the cell.Then, the cell could open the cell membrane outside the cell, leaving the trash without losing any cytoplasm or let anything else in. It's like an air bag in a space ship, or as the double doors at the supermarket air to keep the heat inside the supermarket and the cold air outside.

7. Lysosomes also play a role in disposing of garbage in a cell. If there are broken parts used in a cell, or too many mitochondria, or poisons, then forms a bubble lysosome membrane around them, and enzymes within the lysosome break down these big parts in small molecules that can fit to pass through the cell membrane.Entonces el lisosoma flota en el citoplasmahacia la membrana celular y se utiliza el método de burbujas de aire mismo con la basura fuera de la célula.

8. …Main Parts…VACUOLE:The vacuoles are small pockets in the cytoplasm of a cell of shops.MOLECULE:A molecule is a group of two or more atoms that stick together. PHOTOSYNTHESIS: Photosynthesis is the way some cells on earth pull in light from the sun and use it to make energy to repair and reproduce themselves. OXYGEN: When a star has changed all of the hydrogen atoms into helium, it turns into a red giant and begins to convert the helium atoms into carbon atoms and oxygen atoms.CARBON DIOXIDE: Carbon dioxide is one of the simplest and commonest molecules in the universe. It has only three atoms- one carbon and two oxygen atoms.
