The given blank can be filled with cells.
The extracellular matrix is the protective tissues present as a coating of the cells. Both animals as well as the plant cells have the extracellular matrix, this coating provides support, biochemical protection and mechanical protection from the external environment of the cells. In the plant cells, the cell wall is a type of extracellular matrix.

Diffuse modulatory synapses or neuromodulation function different than simple point-to point synapses.
1. Number of postsynaptic neurons
In neuromodulation neuron uses one or more neurotransmitter to regulate several neurons. In Synaptic point-to-point transmission only one particular neuron receives signal from the presynaptic neuron.
2. Neurotransmitter sin neuromodulation (neuromodulators) are not reabsorbed broken down by the pre-synaptic neuron like those in classic synapse. Neuromodulators stay in cerebrospinal fluid.
3. Receptors are also different: the receptors for the neuromodulators are typically G-protein coupled receptors while in classical chemical neurotransmission, they are ligand-gated ion channels.
4. Neuromodulation is a slow process, while classic synaptic transmission occurs fast.
Answer:
Both B and T cells produce antibodies that attack pathogens
