Chapter 27, Problem 13TYK

Summary Introduction

To review:

The experiment demonstrating whether the protist Euglena shows their movement toward the light. The phototropic movement requires the appropriate light intensity and the wavelength range is to be discussed here.

Introduction:

The euglena comes under protists and has the characteristics of both, male and female. They live in a marine habitat and most of them have chloroplast, which gives them photosynthetic ability. The process of movement toward light via flagellar motion used by Euglena is known as phototaxis.
