Plant cells have mitochondria, which use glucose to produce atp. where does the glucose originate?

The glucose in the plant originates from the cellular process known as photosynthesis.

Explanation:

The glucose in the plant cell originates from the process photosynthesis which takes place in the presence of sunlight and chlorophyll.

The carbon dioxide is combined with water in the leaves of the plant to get converted into glucose.

The light energy is converted into chemical energy. Oxygen is also released as a by-product of this process. The oxygen produced by the plants is also used for the conversion of glucose into ATP in mitochondria.

parasites can detrimentally affect their host, but also must not allow their host to die before they can complete their life cycle. some parasites have complex life cycles with many different hosts, and have had to find ways of persisting in many different environments during the change from one host to another. ectoparasites live outside the body of the host, and can more easily  disperse, but are  more exposed to predators, parasites, parasitoids. endoparasites live inside the body of the host, and are therefore protected from the outside environment. but they can be  attacked by the host's immune system. they have therefore developed  mechanisms for dispersal such as  complex life cycles.

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.  

hope this
