Photosynthesis produces oxygen and water. Photosynthesis is the result of a cycle. Humans use oxygen for respiration, the product produced from human respiration is carbon dioxide. Then plants absorb carbon dioxide from the air and turn it into oxygen with photosynthesis, this goes on and on as a cycle.
Neurotransmitters can affect postsynaptic cells by causing molecular changes in the cells.
The term "chemical messengers of the body" is frequently used to describe neurotransmitters. The nervous system uses these molecules to send information between neurons or from neurons to muscles. A neurotransmitter influences a neuron in one of three ways: excitatory, inhibitory or modulatory.
When a stimulus is potent enough, the chemical messenger neurotransmitter is transferred into the nerve impulse. If it is powerful enough, it will reach the postsynaptic cell and affect the structure of the neuron. And when signal transduction happens, everything mentioned above is completed.

Answer:
1. in animal cell and 3. in plant cell In animals mitochondria transforms energy and chloroplast in plant cell absorb energy from sun light and turns water and carbon dioxide into glucose
Explanation:
1. Mitochondria: It is the powerhouses of a cell oval in shape found in eukaryotic cell.Its a site of cellular respiration. It converts glucose in chemical energy known as ATP (Adenosine triphosphate). ATP provides energy to carry out cellular function by breaking high energy bond.Mitochondria are abundant in cells requires energy to perform functions such as muscle and liver cells.
2. Chloroplast: In plants and algae chloroplast is a site of photosynthesis,it contains a pigment chlorophyll which captures energy from sunlight and turn water and carbon dioxide into glucose as food of plants.
