Explanation

Nissl's granules are groups of ribosomes.

They are found in the neuron’s cytoplasm.

They are involved in protein synthesis.

They essential for neuron growth and repair.

Explanation

Evolution is also referred to as phylogenesis.

It describes the evolutionary development and diversification of a species or taxonomic group over time.

Explanation

Inflorescence is termed cyathium in the genus Euphorbia.

This unique type of inflorescence consists of a cup-shaped structure with a cluster of small flowers.
