Photosynthesis and Respiration 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 H2O 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, (C6H10O5) 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

Part II Plant Nutrition

Nutrients in the soil must first be ________ before being absorbed by the plant Dissolved

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…. pH

The term for nutrients washing out of the soil is Leaching
