Part 1: Introduction, Fungal, & Plant Nutrition
Questions to answer:
1. Explain the role of nutritional systems in contributing to the maintenance of homeostasis in
organisms.
2. Explain the process of fungal nutrition.
3. If autotrophs can make their own food, why do they have any nutritional requirements?
4. How are nutrients absorbed at the roots of plants?
5. How do plants acquire nitrogen? Why is nitrogen necessary for plants?
6. Explain the purpose of the adaptations found in carnivorous plants and parasitic plants.
Things you should make sure you understand:
(feel free to ask questions about them in class)
● Why organisms require nutrients and the consequences of malnutrition.
● How the structure and function of plant organs contribute to plant nutrition.
● The roles of symbiotic relationships in plant nutrition.
Part 2: Animal Nutrition
Questions to answer:
1. Where do the four major stages of nutrition (ingestion, digestion, absorption, elimination) occur
in a human?
2. Copy and fill in the following chart
Organ
Example(s) of Chemical Digestion
Example(s) of Physical Digestion
Mouth
Stomach
Small Intestine
3. Explain how food is absorbed in to the mammalian body.
4. Diagram the blood glucose level feedback loop.
Things you should make sure you understand:
(feel free to ask questions about them in class)
● The structure and function of all parts of the mammalian digestive system.
● How the structure and function of all organs in the mammalian gastrointestinal tract contribute to
nutrition of a mammal.
● Where in the gastrointestinal tract specific types of macromolecules begin to be broken down.
● The roles of symbiotic relationships in the nutrition function of the large intestine in mammals.
● How dentition, obesity, and the structure of the gastrointestinal tract in mammals can serve
adaptive functions.
● How the mammalian digestive system demonstrates the ideas of compartmentalization and
cooperation among organs.
● The causes, effects, and treatments of the disorders demonstrated in the presentation.
