Plant roots grow downward in response to Gravity.

A neuron which carries an impulse to the brain is called a Sensory.

The two examples of effectors are Muscle and glands.

The neuron which carries a message for action to a muscle or gland is known as a Motor.

Tendrils wind around a support in response to Touch.

The substance that accelerates the growth in the stem is Auxin.
Explanation:
The substance which accelerates the growth in stem is auxin.

Auxin is the hormone that causes phototropism in plants.

The hormone which increases the fertility in males is called Testosterone.
Explanation:
Luteinizing hormone (LH) and follicle-stimulating hormone (FSH) cause the testes to produce testosterone and sperm. The pituitary gland, located in the brain, makes these hormones.

A plant’s response to light is called Phototropism.

A root of a plant grows downward. This is known as Geotropism.

Chemicals which are released at the synaptic junction are called Neurotransmitters.
Explanation:
Chemicals released at the synaptic junction are called neurotransmitters.

A plant’s response to gravity is called Geotropism.

Junction between two neurons is called synapse.
Explanation:
Nerve impulse carried out by a gap called synapse between a pair of neurons by means of neurotransmitter. In a synapse, chemical signal is transmitted from axonal end of one neuron to dendritic end of another neuron.

Plant roots grow towards Earth and in the direction of force of gravity.

The response of leaves to the sunlight is called Photonasty.

Our Nervous system allows Us to react to our surroundings. Information from receptors passes along sensory neurons to our brain. Our brain sends impulses along motor neurons to our muscles.

Spinal cord originates from medulla.
Explanation:
Spinal cord originates from medulla. The spinal cord (in yellow) connects the brain to nerves throughout the body.

The basis for modern periodic table is Atomic number.
