Why do reproductive cells only contain half of the DNA an organism needs?

they don't contain half, they contain the full amount of chromosomes
Edited answer:
Because reproductive cells (male & female gametes) are formed after undergoing meiosis to have only single set of chromosomes (haploid). After gametic union both parent contribute one set and hence double set of chromosomes with double amount of DNA is restores in the offspring.

An organism has many specialized cells to carry out the cellular functions it needs to survive what can you determine about this organism?
It has the basic intelligence to respond to its environment and can react to it in order to survive.
What is an organism that lives in or on a host cell?
Ringworms manifest in dogs heart and are considered parasites, which is a small living organism that needs a host to survive.
Does the animal cell contain chloroplast?
No, it doesn't have a chloroplast. Only a plant cell does.
How do the cells of a multicellular organism function?
The main system that serves the needs of individual cells in multicellular organisms is the circulatory system. This is used to take waste away from individual cells and bring in new fuel such as proteins, glucose, and oxygen.
What is an environment that meets the needs of organism?
The organism's natural habitat
Do unicellular orginizms contain many cells?
No, a unicellular cell is a single cell organism that has everything it needs to live.
Most important organism that needs to survive?
cells
How does healthy cells contribute to healthy organisms?
The cells of an organism carry out the functions it needs to live. Healthier cells carry out the functions more efficiently making it easier for the organism to live aka making the organism healthier
Is a tree an organism?
Any mass of living cells that shares the same genetic code base, and which function together in a system is considered an organism. Yes, it is an eukaryote(cells contain a nucleus), autotroph (makes its own food), and is vascular(a more complicated plant). Not only animals can be organisms. And organism is really any living thing. It has systems, needs energy to grow, and grows and develops. Yes, a tree is an organism.
How many cells in micro organisms?
It depends. An organism needs at least one cell.
What do all cells have for storing?
Animal and plant cells contain a nucleus. The nucleus is considered to be the 'brain' of a cell. This means that the nucleus will contain all the information the cell needs.
What do all cells have for storing information?
Animal and plant cells contain a nucleus. The nucleus is considered to be the 'brain' of a cell. This means that the nucleus will contain all the information the cell needs.
An organism has many specialized cells to carry out the cellular functions it needs to survive what can you determine about this organism?
It has the basic intelligence to respond to its environment and can react to it in order to survive.
What is the purpose of somatic cells?
Somatic cells are body cells that contain a full set of chromosomes. I imagine that a somatic cell donor donates healthy body cells to someone who needs them.
Why cells are the building blocks of life?
Cells can be considered the building blocks of life because every living thing is made up of cells or even a single cell. Organisms big and small are made up of cells that contain all the necessary parts to carry out processes which are necessary for life. Different types of cells perform different types of functions which work together as a system to provide an organism with what it needs.
What are some characteristics of viruses?
some characteristics of a virus: - needs a host - can contain DNA or RNA - can have an envelope cell - is an acellular organism
How does the mitotic cell division relate to the cell cycle?
It still needs cells to form the organism. If cells aren't present, tissues won't be formed organs won't form to make organ systems and make organisms. THE CELL CYCLE cells-->tissues -->organs-->organ system-->organism
