Plants' Nutritional Needs • As plants are living organisms, they need to obtain energy to carry out their life processes, as we saw before.

• In order to produce energy, plants require certain factors, elements, and compounds.

• Basically, we can classify these requirements as:

NON‐MINERAL These are found in the air and water.

Examples: Hydrogen (H), Oxygen (O) and Carbon (C)....and also energy from the SUN.

MINERAL These are found in the soil and dissolved in water. Depending on how much they are needed, they are called Micro‐ or Macro‐ nutrients.

13

14

Plants Micronutrients • Micronutrients are those elements essential for plant growth which are needed in only very small (micro) quantities.

• The micronutrients are boron (B), copper (Cu), iron (Fe), chloride (Cl), manganese (Mn), molybdenum (Mo) and zinc (Zn).

• Recycling organic matter such as grass clippings and tree leaves is an excellent way of providing micronutrients (as well as macronutrients) to growing plants.

Optional Assignment: Find the functions of the micronutrients in plants.

15

Plants Macronutrients • There are 13 macronutrients that are in the soil, or dissolved in water, and are essential for plants.

• Sometimes there are not enough of these mineral nutrients in the soil for the plants to grow healthy.

• That's why farmers use fertilizers to complement the nutrients from the soil.

• Macronutrients are divided in two groups: Primary Nutrients

Secondary Nutrients

Nitrogen (N), Phosphorus (P), and Potassium (K).

These major nutrients usually are lacking from the soil first because plants use large amounts for their growth and survival.

Calcium (Ca), Magnesium (Mg), and Sulfur (S). There are usually enough of these nutrients in the soil so fertilization is not always needed.

How are the these macronutrients used in plants?

16

The Soil • Plants usually absorb almost all their nutrients from the soil.

• Therefore, the soil is a very important factor in the growth and development of plants.

• The composition of the soil will determine the presence or absence of certain, or all plants.

• The makeup of a soil (soil texture) and its acidity (pH) determine the extent to which nutrients are available to plants.

• Soil texture affects how well nutrients and water are retained in the soil.

• An ideal soil contains equivalent portions of sand, silt, clay, and organic matter.

17

But, what are all these nutrional needs for?

PHOTOSYNTHESIS YouTube Video

19

PHOTOSYNTHESIS • Plants are called producers, because they have the capability to produce their own food.

• This happens through the process of Photosynthesis.

• Photosynthesis has two stages: Light‐dependent reaction and Dark reaction.

• The energy obtained from the Sun impacts the molecule of Chlorophyll (in the organelle called Chloroplast).

• The light energy is used to convert carbon dioxide and water into sugar and oxygen.

How are materials distributed through out the plants?

• Different materials, or substances, are transported in living organisms in different ways.

• In the case of plants, there are two ways, depending on the type of plants.

• In fact, transportation of materials determines a classification for plants.

NON‐VASCULAR

VASCULAR

Initial and inefficient way to transport materials in plants.

The substances are moved from cell to cell.

As a consequence, plants are small.

Transport their materials through two tubes: Xylem and Phloem.

These are specialized tissues. Plants can be taller and stronger.

Nutrition in Animals

27

Animal Nutrition • Animals need a variety of nutrients to meet their needs.

• These nutrients include fats and carbohydrates that provide energy, proteins that furnish amino acids, vitamins that serve as co‐factors for enzymes and perform other functions, ions required for water balance and for nerve and muscle function, and selected elements that are incorporated into certain molecules synthesized by cells.

28

29

Obtaining Food • Once food is ingested, it is processed in an alimentary canal that begins at the mouth and ends at the anus.

• Food processing frequently begins with tearing or chewing action by a beak, teeth, or other mouthparts.

• Among animal species, there is a strong correlation between the size and shape of mouthparts and their function in capturing and processing food.

Check these mouths......

30

31

32

Digesting Food • In many animal species, chemical digestion of food begins in the mouth, where salivary enzymes start breaking down food.

• Once food is swallowed, it passes down the esophagus via peristalsis.

• Digestion continues in the stomach, where a highly acidic environment denatures proteins.

• From the stomach, food passes into the small intestine, where it is mixed with secretions from the pancreas and liver.

• Carbohydrate digestion is completed by pancreatic amylase; fats are emulsified by bile salts and digested by lipase.

• Cells that line the small intestine absorb the nutrients.

• Water reabsorption is completed in the large intestine, where feces forms.

33

34

Beyond the class information....

Compare and contrast the human digestive system with: • The Cow's digestive system, • The Chicken's digestive system, • The Fish's digestive system, • The Snake's digestive system.
