Why So Stumped?

Biology

100

Besides releasing oxygen, how else do trees help us?

Taking in carbon dioxide

"one of the most cost-effective methods of curbing urban air pollution levels and combating the urban heat island effect"

200

What are the products of Photosynthesis?

Glucose/Sugar - the end result of the conversion of solar energy to chemical energy; represents stored energy that can be used by the plant, or consumed by other organisms

Oxygen - released into the atmosphere through the plant’s leaves

Water 

300

Which one of these is not a function of the leave?

a. Manufacture of food

b. Site for the interchange of gases between the atmosphere and the plant body

c. Defense against the spread of decay

d. Stores food

e. Evaporation of water.

C. Defense against the spread of decay

What are the three functions of a tree trunk?

Transports water, nutrients, and food between leaves and roots

Provides structural support

Stores Food

500

What kind of tree can survive in freshwater and saltwater?

Mangrove trees

Their roots extract fresh water from seawater

Some excrete salt from leaves

Store freshwater in leaves (like succulents)

Tree Care

100

When cleaning a tree pit, loosening the soil allows ____ and _____ to penetrate through the soil.

Water and Oxygen

200

What is the purpose of the wire fence?

Protection (from deers)

300

What is the purpose of pruning? 

*pruning = grooming

Remove diseased or old branches

Enables the tree to grow new and healthy branches (better fruit)

400

What is mulch? (uses and what is made of)

Made of organic material (decomposing) 

Placed over the soil surface to enhance landscape beauty, improve soil conditions, protect plants from foot traffic and lawn equipment, and suppress weeds

500

What is the 3-3-3 rule?

Where and how you should add mulch

3 inches of free space around the trunk to prevent roots from suffocating

3 feet of mulch around the trunk to prevent weed and grass growth

3 inches high pile to make sure roots do not dry out

Environmental Value

100

How can trees help conserve energy?

Trees placed strategically around a home can cut  air conditioning costs by up to 50%

Reducing the energy demand for cooling leads to a reduction in carbon dioxide and other pollution emissions from power plants

200

About how much percent of the world’s greenhouse gas emissions is due to deforestation?

a. 14%

b. 20%

c. 32%

d. 47%

b. 20%

300

How do trees improve water quality?

Slows rainwater as it falls and helps it soak it into the soil

Helps prevent rainwater runoff which can carry pollutants on streets into nearby water bodies (natural filters)

400

What are some threats to trees and forests? (list 3)

Deforestation

Climate change

Invasive species

Insects

Forest fires

Frost damage

Diseases 

Animal damage

500

How can trees exacerbate, or worsen, air quality in an area?

“green “ roof effect: a canopy of trees clustered together can prevent pollutants from escaping the streets

Trees can not do anything about pollutants other than CO2 (NOx, PM)

True or False

100

An angiosperm is a type of plant that has seeds unprotected by an ovary or fruit. A conifer is an example of an angiosperm

False. 

An angiosperm is a type of plant that has flowers and produces seeds enclosed within a carpel.

200

The largest tree (in volume) is located in Brazil.

False.

The General Sherman Tree, Sequoia National Park in California

Height 275 ft

Diameter 25 ft

Volume of trunk 52,500 cu.ft

300

Over the course of its life, a single tree can absorb one ton of carbon dioxide.

True.

400

Brazil, Madagascar, and Australia have the highest totals of endemic trees.

*endemic means that they are unique to an area, that species can not be found elsewhere in the world

False. 

Brazil, Colombia, and Indonesia have the highest totals.

60,065 known species 

Nearly 58% are endemic

500

The oldest living organism on Earth is a tree. (based on what humans have discovered)

True. 

Methuselah, great basin bristlecone pine

Located in the White Mountains of Inyo County (Eastern California) 

Currently 4851 years old
