Question
Chapter 27.2, Problem 3BC
Summary Introduction
To determine: The heterotrophic eukaryote that move to its source of food in human gut with the help of flagella with reference to figure 29.8b given in the text book.
Introduction: Different types of organisms use different means to get access to the source of food. Some organism use flagella while some other heterotrophic eukaryotes use fruiting bodies and hyphal filaments in order to get food.

LAB 5: SALINIZATION OF SOIL
Why was it necessary in the experimental design to have some seeds germinating in pure water?
Exercise II Bryophyta: The Mosses de
Examine with the dissecting microscope the mosses that are available. The "leafy" plants
are the gametophytes and any elongated structures growing above them are the
sporophytes. (See text Figure 16-27, page 385.)

Figure 5. Moss Life Cycle (drawn by Stephanie Preising, SCSU '20)
Obtain a gametophyte and observe its symmetry, its leaf like structures, its axis (pseudo-
stem), and is rhizoids. Some species of mosses are unisexual; others are bisexual.
The moss gametophyte originates as budlike structures that develop from a protonema
(plural: protonemata), a system of branching filaments derived from a germinating spore.

In a common eudicot pattern of development for the common bean in the figure, the radicle emerges from the seed (1), then begins to develop into a primary root that grows down into the soil. As this occurs, the hypocotyl emerges from the seed and bends into the shape of a hook (2). The bent hypocotyl lengthens and pulls the cotyledons upward (3). When the hypocotyl reaches the soil surface, exposure to light causes it to straighten (4). Primary leaves emerge from between the cotyledons and begin photosynthesis. The cotyledons typically undergo a period of photosynthesis before shriveling (5). Eventually, the cotyledons fall off the lengthening stem, and the young plant's new leaves produce all of its food.
