A process a cell uses to obtain and use energy is called cellular respiration (also called oxidative metabolism), which is mecessary to sustain a cell's life. It converts biochemical energy from nutrients into adenosine triphosphate (ATP), and then releases the cell's waste products.
NOTE: If this does not answer your question, please ask a more specific question.
An organelle is a small structure in cells that performs a specific function, such as the mitochondria for energy production or the chloroplast for photosynthesis. Organelles are like specialized compartments within the cell that help carry out essential processes for the cell's survival and function.
In a unicellular organism, typically a single cell carries out the functions of taking in food, digesting it, and obtaining nutrients. This cell performs all necessary activities for the organism's survival.
No, DNA is not considered an organelle. DNA is a molecule found in the nucleus of cells and contains the genetic information necessary for the development, functioning, and reproduction of living organisms. Organelles are specialized structures within cells that have specific functions.
A large, double membrane-bound organelle found in eukaryotic cells. Contains DNA and RNA. Organelle - A membrane-bound sub-cellular structure found in eukaryotic cells. The Cell nucleus, mitochondria, ER, and golgi apparatus are all examples.
The largest, and most easily visible organelle found in MOST cells is the nucleus. It is large and dark staining, and quickly seen in a microscope. However, only eukaryotic cells have a nucleus. Prokaryotic cells don't have organelles at all.
The organelle that directs a cell's activities is the nucleus.
The organelle that directs a cell's activities is the nucleus.
In plant cells, the chloroplast is an organelle that performs photosynthesis, and he mitochondria is an organelle that produces ATP (energy).

Mitochondria
An organ is a collection of cells that perform a function (liver, skin, muscles) whereas an organelle is something INSIDE a cell which performs a function for the cell (ribosome, mitochondria)
The nucleus is the largest organelle in animal cells.
