Plant Nutrients What are the needs of plants Guided notes
Part I Photosynthesis and Respiration
Photosynthesis is the ability of green plants to convert ________energy into stored chemical energy. Solar 1
Photosynthesis takes place in the ____which contains green pigment called ______ Chloroplast Chlorophyll 2
In addition to sunlight, photosynthesis needs _____ and _____ to work Carbon Dioxide H 2 O 3
Photosynthesis produces sugar, water, and ______. 4
Stored energy from photosynthesis is in the form of _____ Glucose 5
Sugar created by photosynthesis maybe converted to _______for longer term storage. Carbohydrates (starch) 6
Starch - 1. A naturally abundant nutrient carbohydrate, (C 6 H 10 O 5) found chiefly in the seeds, fruits, tubers, roots, and stem pith of plants, notably in corn, potatoes, wheat, and rice.
Carbohydrates - Any of a group of organic compounds that includes sugars, starches, celluloses, and gums and serves as a major energy source in the diet of animals. These compounds are produced by photosynthetic plants and contain only carbon, hydrogen, and oxygen, usually in the ratio 1: 2: 1.
The process of breaking down stored energy is _______. 7
Plant growth mostly takes place at _______? Night 8
In order to break down the stored sugars, plants must produce chemicals called______? • Four plant enzyme groups exist: • Proteases - break long protein chains into smaller amino acid chains and eventually into single amino acids • Amylases - reduce polysaccharides to disaccharides: lactose, maltose, and sucrose • Lipases - break triglycerides into individual fatty acids and glycerol • Cellulases - digest specific carbohydrate bonds found in fiber 9
The equation for respiration is the ______of photosynthesis. Opposite 10

How many essential nutrients are there for plants? 16 (some sources cite 17 or 18)
Nutrients needed in the largest amounts are called?
Nutrients that are needed in low amounts are called. Micronutrients
A shortage of a given nutrient needed by the plant is a …. Deficiency
What is another name for micronutrients? Trace elements
The acidity or alkalinity of the soil is its…. p. H
The term for nutrients washing out of the soil is Leaching
