Explanation:
A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane.
Answer: Synapse connects neurons and neurotransmitters are the chemicals that help in the communication of neurons.
The given statements can be completed as-
The synapse connects the axon of one neuron with the dendrite of another neuron to relay messages.
The cells release chemicals known as neurotransmitters ( such as acetylcholine) into the synaptic gaps to communicate with one another.
Neurotransmitter are the chemical messengers that carry chemical signal to the target neuron where it gets converted into electrical impulses. Synapse is a place or gap between the axon terminal of one neuron and the dendrite of another neuron.

Answer:
<em>Staphylococcus</em> is a gram negative bacteria that belongs under family Staphylococcaceae.The name is given as their body shape is spherical(Cocci).
Explanation:
The important characters of Staphylococcus are-
- <em>Staphylococcus </em>are facultative anaerobic organism.
- They are spherical in shape.
- As they are gram positive bacteria, thus the cell wall is prominant and easily stained with crystal violet and they are grown in bile salts.
- They are capable of producing coagulase enzyme that cause blood clot.
- These bacteria divides along two axes and thus form clump of bacteria.
Difference between <em>S. aureus</em> and <em>S.epidermis-</em>
- <em>S. aureus</em> is round in shape where as<em> S.epidermis</em> is spherical in shape.
- <em>S. aureus</em> is a opportunistic pathogen that cause different diseases like skin infection where as<em> S.epidermis</em> is non pathogenic bacteria.
- <em>S. epidermis</em> form white raised cohesive colony with 1-2 mm in diameter whereas, <em>S.aureus</em> form golden yellow color colony.
- <em>S.aureus</em> causes hemolysis when it is grown in agar plate whereas <em>S.epidermis</em> is not hemolyse in blood agar plate.
