The sliding filament theory explains how these cross-bridges are formed and the subsequent contraction of muscle. The Sliding Filament Theory For a contraction to occur there must first be a stimulation of the muscle in the form of an impulse (action potential) from a motor neuron (nerve that connects to muscle).
A plant scientist is a biologist who focuses on various types of plants, usually those grown as crops for food, fiber, and other purposes. This work can involve field and lab work on a variety of topics, from improving yields to developing more nutritious food plants for the purpose of fighting hunger in underdeveloped nations.
A plant physiologist is a scientist who concentrates on studying, understanding and often teaching the integral biological processes of plants.These professionals spend most of their time conducting research on certain elements of plant life.iology and the organic nature of plant life is foundational, but the day-to-day work of an average plant physiologist involves a high degree of both chemistry and math. Physiologists study the internal workings of plants, often on a cellular level.
