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

He is the bread of life! 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.

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.

FoodFood

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

Talk about this:

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 Water and mineral transport from roots to aerial parts of the plant.

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.

Movement Unidirectional (Moves up the plant's stem)

Bidirectional (Moves up or down the plant's stem from "source to sink")

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?
