Agnieszka K.
Answer:

Photosynthesis contains two reactions: light and dark. Light reactions need light to produce organic energy molecules (ATP and NADPH). They are initiated by colored pigments, mainly green colored chlorophylls. Dark reactions make use of these organic energy molecules (ATP and NADPH). This reaction cycle is also called Calvin Cycle, and it occurs in the stroma.

Question:

What is an atom?

Answer:

Atoms are really hard to wrap our brains around because they are unbelievably small. Atoms are composed of particles called protons, electrons and neutrons. Protons carry a positive electrical charge, electrons carry a negative electrical charge and neutrons carry no electrical charge. The protons and neutrons cluster together in the central part of the atom, called the nucleus, and the electrons 'orbit' the nucleus. Imagin a cotton candy as an atom with all the particles. Cotton candy is made of sugar. Where is sugar? Everywhere ! Right? It is for electrons, there are everywhere around the nucleous.
