Uses of Glucose in Plants

What are the 6 main uses of glucose?

Give the word equation for respiration.

Answer explanation

The word equation for respiration is: Glucose + Oxygen → Carbon Dioxide + Water + Energy. This summarizes the process where glucose and oxygen are converted into carbon dioxide, water, and energy.

Where does respiration occur?

Answer explanation

Respiration occurs in the cells of living organisms, specifically within the mitochondria, where oxygen is used to convert glucose into energy.

Why does a plant store its glucose as starch?

Answer explanation

Plants store glucose as starch because starch is a more compact and stable form of energy storage. It allows them to store excess glucose efficiently for later use during periods of low photosynthesis.

In which 3 organs does a plant store its starch in?

Answer explanation

Plants primarily store starch in three organs: roots, stems, and leaves. Roots store starch for energy reserves, stems can store it for growth, and leaves produce starch through photosynthesis.

Name a storage organ that we can eat.

Answer explanation

A common storage organ we can eat is the potato. It stores starch and is a staple food in many diets, making it a great example of an edible storage organ.

Glucose is turned in which 'L' substance for storage in seeds.

Answer explanation

Glucose is converted into lipids for storage in seeds. Lipids serve as energy reserves, making them essential for seed development and germination.

Lipids are made up of which 2 separate substances?

Answer explanation

Lipids are primarily composed of two types of molecules: glycerol and fatty acids. Glycerol serves as the backbone, while fatty acids are long hydrocarbon chains that attach to glycerol, forming various lipid structures.

What 2 products, that we extract from plant seeds can we use?

Answer explanation

Two products extracted from plant seeds are oil and protein. Seed oils are commonly used for cooking and industrial purposes, while proteins are essential for nutrition and are found in various food products.

How is glucose turned into sucrose?

Answer explanation

Glucose is converted into sucrose through a condensation reaction, where a glucose molecule and a fructose molecule combine, releasing a water molecule. This process is catalyzed by the enzyme sucrose synthase.
