NUTRITION IN HUMANSSecond Period2nd Indicator
Objective:To recognize the different nutrition types to value importance of nourishment in living things.
Indicator:Knows the different types of nutrition in Animals, humans, and plants to take advantage of their benefits.
Biblical principle
• Genesis 1:29-30New International Version (NIV)• 29 Then God said, “I give you every seed-bearing
plant on the face of the whole earth and every tree that has fruit with seed in it. They will be yours for food. 30 And to all the beasts of the earth and all the birds in the sky and all the creatures that move along the ground—everything that has the breath of life in it—I give every green plant for food.” And it was so.
Nutrition
Nutrition can be defined as the process by which an organism obtains food which is used to provide energy and materials for its life sustaining activities
FoodFood is an organic
compound which organisms can use as a source source
of energyof energy for metabolic processes.

Digestion
• Digestion is the breaking down of food into forms that our bodies can use. Our bodies use food as fuel to provide energy for work, play and growth. Your digestive system is responsible for converting the food we eat into energy for our bodies to use
The Digestive System
• Esophagus• Stomach• Small Intestine• Large Intestine• Gall bladder• Liver• Pancreas
Esophagus
• the tube that connects your mouth and your stomach
Stomach• A stretchy bag that holds
your food after you eat
• Helps to break food into smaller pieces so your body can use it for energy and nutrition
Esophagus
Small Intestine• Tube that is 20 feet
long.
• Continues to digest food
• Food stays in your small intestine for 4 to 8 hours
Small Intestine
Large Intestine• Tube that is 5 feet
long
• Gets waste from small intestine
• Waste stays for 10 to 12 hours
Large Intestine
Gall Bladder
• Storage tank for bile (a greenish-yellow liquid) that helps your body break down and use fats
• Located under your liver
• Shaped like a pear
Liver
• Factory for antibodies and bile
• Stores vitamins and sugars until your body needs them
Liver
Pancreas
• Helps you digest food by breaking down sugars

Plant nutrition“Plant nutrition”
specifically does not refer to photosynthesis.
Plants uptake nutrients from the soil directly by roots
Plants require 13 mineral nutrient elements for growth. The elements that are required or necessary for plants to complete their life cycle are called essential plant nutrients, each has a critical function in plants and are required in varying amounts in plant tissue
• Name Chemical Relative Function in plant symbol % in plant to NPrimary macronutrients• Nitrogen N 100 Proteins, amino acids• Phosphorus P 6 Nucleic acids, ATP• Potassium K 25 Catalyst, ion transport
Secondary macronutrients• Calcium Ca 12.5 Cell wall component• Magnesium Mg 8 Part of chlorophyll• Sulfur S 3 Amino acids• Iron Fe 0.2 Chlorophyll synthesis
Micronutrients• Copper Cu 0.01 Component of enzymes• Manganese Mn 0.1 Activates enzymes• Zinc Zn 0.03 Activates enzymes• Boron B 0.2 Cell wall component• Molybdenum Mo 0.0001 Involved in N fixation• Chlorine Cl 0.3 Photosynthesis reactions
Phloem and Xylem
Function Transportation of food and nutrients such as sugar and amino acids from leaves to storage organs and growing parts of plant. This movement of substances is called translocation.
Water and mineral transport from roots to aerial parts of the plant.
Movement Bidirectional (Moves up or down the plant's stem from "source to sink")
Unidirectional (Moves up the plant's stem)
PHLOEM XYLEM
Phloem and Xylem Structure
Class ActivityReflect on Matthew 4:4.But he answered and said, It is written, Man shall not live by bread alone, but by every word that proceeds out of the mouth of God.
•How can you nourish your spirit and make it strong?•Do you think you need only food to live? Why ? Why not?•What is the word that proceeds out of the mouth of God? Where can we find it?
