Name the cleansing organelle in the cell

A cells is the smallest living organism and the basic unit of life on earth. Together trillions of cells make up the human body. Cells have three parts: the membrane, the nucleus, and the cytoplasm. People can think of cells as tiny packages that contain minute factories, warehouses, transport systems, and power plants. They function on their own, creating their own energy and self-replicating — the cell is the smallest unit of life that can replicate. Cells are the basic units of life. The body contains around Cells also communicate with each other. Whether in plants, humans, or animals, they connect to create a solid, well formed organism. In humans, cells build tissues, tissues form organs, and organs work together to keep the body alive. Robert Hooke first discovered cells in the 1600s. He gave them their name because they resembled the “ cella,” the Latin term for “small rooms” where monks lived in monasteries.

For instance, a sperm cell resembles a tadpole, a female egg cell is spherical, and nerve cells are essentially thin tubes. Despite their differences, cells often share certain structures. These are known as organelles or mini-organs. Below are some of the most important: Nucleus The nucleus represents the cell’s headquarters. There is typically one nucleus per cell. However, this is not always the case. ...

On the left is a circle representing an animal cell. The cell contains many cell parts with different shapes. A small bean-shaped cell part is labeled mitochondrion. A medium-sized circular cell part that has squiggly lines inside is labeled nucleus. The outermost part of the cell, which is shown as an outline of the cell, is labeled cell membrane. On the right is a four-sided figure with rounded corners that represents a plant cell. The cell contains many cell parts with different shapes. A small green oval with stacks of darker green ovals inside is labeled chloroplast. A medium-sized circle that has squiggly lines inside is labeled nucleus. The outermost part of the cell, which is shown as a thick outline of the figure, is labeled cell wall. A thinner layer just inside the cell wall is labeled cell membrane. A small bean-shaped cell part is labeled mitochondrion. Actually, you are partially wrong. Plant cells do indeed have chloroplasts while animal cells do not, but both types of cells have mitochondria. Animal cells have structures called lysosomes (which are basically organelles containing an extremely acidic fluid to break down objects) and centrosomes (used in cell reproduction). Plant cells have neither of these. Plant cells have cell walls that surround their cell membrane, and large central vacuoles that make the cell rigid. Animal cells have neither of these structures. Additionally, animal cells usually have an irregular shape, while plant cells are more recta...

The functions of cell organelles Question The table below list organelles, their function and the types of cell that they can be found in. Can you fill in the blanks to complete the table? Cell structure Description Function Cell type Cell wall Freely permeable layer surrounding cell membrane. The cell wall of plant cells is made from cellulose. This gives them a rigid structure. Supports and strengthens cell ? Cell membrane Selectively permeable double layer of lipid and protein molecules ? All cell types ? Fluid enclosed by the cell membrane, containing organelles and ribosomes Location of many chemical reactions All cell types Mitochondria ?-shaped structures found in ? Location where aerobic respiration occurs and most of the cell's ATP is produced Animal cell, plant cell or fungal cell Chloroplasts Disc-shaped structures found in cytoplasm Location where photosynthesis occurs and sugar is produced ? ? Compartment in cell containing solution of salts and sugars (cell sap) Water storage and maintenance of turgor within the cell Plant cell Ribosomes Small complexes found in cytoplasm Location where ? are connected together to produce proteins All cell types Plasmids ? Contains genes that help cell to function, eg genes for antibiotic resistance Bacterial cell ? Compartment in cell where DNA is stored as chromosomes Controls activities of cell Animal cell, plant cell or fungal cell Reveal answer down Cell structure Description Function Cell type Cell wall Freely permeable...

© 2014 How do cells accomplish all their functions in such a tiny, crowded package? Eukaryotic cells — those that make up cattails and apple trees, mushrooms and dust mites, halibut and readers of Scitable — have evolved ways to partition off different functions to various locations in the cell. In fact, specialized compartments called organelles exist within eukaryotic cells for this purpose. Different organelles play different roles in the cell — for instance, mitochondria generate energy from food molecules; lysosomes break down and recycle organelles and macromolecules; and the endoplasmic reticulum helps build membranes and transport proteins throughout the cell. But what characteristics do all organelles have in common? And why was the development of three particular organelles — the nucleus, the mitochondrion, and the chloroplast— so essential to the evolution of present-day eukaryotes (Figure 1, Figure 2)? In addition to the nucleus, eukaryotic cells may contain several other types of Like the plasma membrane, organelle membranes function to keep the inside "in" and the outside "out." This partitioning permits different kinds of biochemical reactions to take place in different organelles. Although each organelle performs a specific function in the cell, all of the cell's organelles work together in an integrated fashion to meet the overall needs of the cell. For example, biochemical reactions in a cell's mitochondria transfer energy from fatty acids and pyruvate mo...
