Definition: A leaf-like part of a plant that produces large spores.

Example: The megasporophyll is essential for the reproduction of certain plants.

Definition: A measure of explosive power that is equal to the energy released by one million tons of TNT.

Example: The bomb had a power of ten megatons, making it one of the most powerful ever created.

Definition: The amount of explosive power that a bomb or a group of bombs can produce, measured in megatons.

Example: The megatonnage of the nuclear arsenal was a major concern for global security.

Definition: Describing something that involves or contains very large amounts of vitamins.

Example: Some people believe that taking megavitamin supplements can improve their health significantly.

Definition: A large amount of a vitamin that is much more than what the body needs for good health.

Example: Some people take megavitamins to try to improve their health, but it's important to be careful with high doses.

Definition: A unit of electrical potential equal to one million volts.

Example: The power plant generates electricity at a high voltage of several megavolts.

Definition: A unit of power that is equal to one million watts, often used to measure the output of power plants.

Example: The new solar farm has a capacity of 100 megawatts.

Definition: A unit of electrical resistance equal to one million ohms.

Example: The circuit has a resistance of five megohms, which is quite high.

Definition: A type of cell division that occurs in sexually reproducing organisms, which reduces the chromosome number in reproductive cells, resulting in the formation of gametes or spores.

Example: Meiosis is essential for sexual reproduction as it produces gametes with half the number of chromosomes.

Definition: Related to the process of cell division that reduces the number of chromosomes in reproductive cells.

Example: During meiotic division, the chromosome number is halved to produce gametes.

Definition: In a way that relates to the process of meiosis, which is a type of cell division that reduces the number of chromosomes in reproductive cells.

Example: The cells divide meiotically to ensure genetic diversity in the offspring.
