About: How organelles help cells survive.

Explanation:

Is important at first to know that every cell in your body contains organelles (structures that have specific functions). Just like organs in the body, each organelle contributes in its own way to helping the cell function well as a whole. The nucleus, mitochondria and chloroplasts are all #organelles.

Despite their central importance to cell function (and therefore to all life), organelles have only been studied closely following the invention of the transmission electron microscope, which allowed them to be seen in detail for the first time.

#Specialised organelles
Some organelles are found only in some cell types. They have roles that are important to the specific function of that cell type.

Chloroplasts (left) are the site of photosynthesis in plant cells, storage granules (centre) provide a storage site for proteins in secreting cells.

Microvilli (right) aid absorption of nutrients during digestion by increasing the surface area of cells in the intestinal wall

#HELPING CELLS

Core organelles are found in virtually all eukaryotic cells.
They carry out essential functions that are necessary for the survival of cells harvesting energy, making new proteins, getting rid of waste and so on.
Core organelles include the nucleus, mitochondria, endoplasmic reticulum and several others.

The primary cilium (which has recently been shown to help cells sense their surroundings) may also be a core organelle because it seems to be present on most cells.

Different cells have different amounts of some organelles. Cells that use a lot of energy tend to contain large numbers of mitochondria (the organelle responsible for harvesting energy from food).
That’s why very active muscle cells are often full of mitochondria.
