Sperm cells need a tail to get food or energy while the egg isnt alive yet to need emergy......?
red blood cells and white blood cells the red blood cells keep us a live and the white blood cells fight off disease and infection. To complete the answer, the red cells carry oxygen from the lungs to the tissue, etc., cells that need it.
If it is alive then it is an oganism. You just need to know if it's alive. Anythin' that is living is an organism. depends on the cell and the level of organization: bacterial cells are considered organisms liver cells are not organisms read up on cell theory (not the marxist kind) that should clarify the definition of organisms for you.
All cells must do work to stay alive and maintain their cellular environment. The energy needed for cell work comes from the bonds of ATP.
Grasses are plants, and plants are living things. You need to re-think your question.
They need to stay alive to support the organism
so that they can be alive
So we can be ALIVE

Oxygen, Energy, and Nutrients
your body
how cells keep you alive is from your nutrients and from your stomach
Oxygen and nutrients
dissloved in fluid.
All living things are organisms. There is no such thing as a living cell that is not an organism.
None all living things need cells to live the cells have all things needed for life so if something doesn't have cells it is not alive.
Specialized cells are dependent on other specialized cells because they need to live off other cells otherwise specialized cells wouldn't exist. Every specialized cell is designed to carry out a special function, there for we need a bunch of different specialized cells for the entire organism to survive.
