Atomic Number

Atoms with the same number of protons but different numbers of neutrons are called __.

Isotopes

An attraction between oppositely charged ions is known as __.

Ionic Bond

Electrons are negatively charged and orbit the nucleus in __.

Shells

A __ bond involves the sharing of electrons between two atoms.

What is photosynthesis?

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll, primarily converting carbon dioxide and water into glucose and oxygen.

Photosynthesis converts _ energy into chemical energy.

light

What gas do plants take in during photosynthesis?

Plants take in carbon dioxide during photosynthesis.

What is cellular respiration?

Cellular respiration is the process by which cells convert glucose and oxygen into energy, producing carbon dioxide and water as byproducts.

What is the main purpose of cellular respiration?

The main purpose of cellular respiration is to convert glucose into ATP (adenosine triphosphate), which cells use for energy.
