Science Quiz 1 Module 1 (content)

The most important minerals needed by plants are _____________ compounds

nitrogen

This layer contains the chlorophyll:

palisade layer

The best source for vitamins is:

plants Plants are excellent sources of vitamins. Unlike animals, plants can make and store vitamins.

The function of enzymes in plants is to:

produce simple glucose from starch

Legumes are plants that produce:

protein

_______________________ is gas given off in respiration, absorbed from the air by plants in photosynthesis.

Carbon dioxide

_________________________- is produced by human respiration.

Carbon dioxide

Fungi produce food through photosynthesis. (True or False)

False, Cells that are not green are not able to produce their own food. The fungi are another group that cannot produce its own food. Fungi are organisms which physically look like plants, but they are actually parasites or saprophytes. Examples of fungi are mushrooms, yeast, and mold.

The only function of glucose is to make starch. (True or False)

False, Glucose can be used by plants to make many other foods. One example of these foods is fats and oils. Some of the most important foods are oils from olives, coconuts, peanuts, and cotton.

Most plants can make the proper nitrogen compounds (fertilizer) which they need. (True or False)

False, However, most plants must obtain the proper nitrogen compounds from the soil; therefore, they require organic or chemical fertilizers.

It is probable that photosynthesis could have started from natural chemical reactions (combinations) because it is basically a simple process. (True or False)

False, Many scientists have concluded from all these observations about plants that the complex process of photosynthesis which sustains life on earth could not have started by accident.

Most plants absorb the nitrogen which they need from the air. (True or False)

False, Minerals and water are taken up through the roots of the plant. The most important minerals are nitrogen compounds.

Seeds obtain their energy (food) directly from the soil as soon as they are planted. (True or False)

False, Often, the fats and oils are stored in the seeds. This high-energy food is used by the seeds at germination time to get the growth process started. in other words the seed stores energy in itself to get started

Photosynthesis is possible only in the stems. (True or False)

False, Photosynthesis is not limited to leaves. Any green cells that have chlorophyll can act as photosynthesis factories.

A plant only requires the correct chemicals to make plant food. (True or False)

False, The free energy required for photosynthesis is supplied by the sun in the form of light. Other substances, such as water, chlorophyll, and gas made out of molecules of carbon and oxygen, are also needed.

A leaf is a simple combination of various chemicals. (True or False)

False, The leaf of a green plant contains a very complex chemical mechanism.

Plants make starch and protein but only animals make lipids and oils. (True or False)

False, olives, coconuts, peanuts, and cotton are examples of plants that make oils

Scientists can produce plant food just like a leaf can. (True or False)

False, scientists cannot reproduce this

Remember that we see the color of objects because that color bounces off the object and back to our eyes. The other colors are soaked up by the shirt like a sponge. Why do you think the green light is the least effective color to give plants energy to grow?

I think green light is the least effective color to give plants energy to grow because, the green light is bouncing off the green plant which means less light for the plant.

According to appearances, which light produces the healthiest plant?

Red

_____________________ is the chemical process of cells doing work; breathing

Respiration

Which Bible Scripture states that all of the natural world provides evidence that it was created by God?

Romans 1: 20

___________________ is an organism that gets its food from decaying plants or animals.

Saprophyte

Manure is an organic fertilizer (True or False)

TRUE,

What is true about cells in animals?

They cannot produce food.

A thousand simple sugar molecules can be stacked together to make starch. (True or False)

True, As many as one thousand glucose units can be stacked together to form one starch unit. These starch units are reservoirs of energy and can be compared to a chemical battery.

Plants release oxygen gas to the atmosphere. (True or False)

True, Plants, however, need this carbon dioxide gas to keep their leaf factories working. In photosynthesis, plants give off oxygen as a by-product.

Proteins are complex molecules. (True or False)

True, Proteins (nitrogen compounds) are also made from simple glucose. The making of proteins is very complex.

In order for photosynthesis to work, all the necessary chemicals and biologic mechanisms must be available. (True or False)

True, The leaf works much like a factory. Without the raw materials and all the necessary biologic mechanisms of a plant, no photosynthesis occurs.

Plants form the starting point of the food chain. (True or False)

True, plants for the foundation of every food chain

Remember that we see the color of objects because that color bounces off the object and back to our eyes. We see a person's shirt as red because the red color bounces off the shirt and back to our eyes. The other colors are soaked up by the shirt like a sponge. Why do you think plants appear green?

because most of the color green bounces off the leaves to our eyes

Why does the text say that the process of photosynthesis feeds the whole world?

because plants provide the necessary vitamins and minerals which sustain animals and people because all food ultimately starts with plants

The chemical substance needed to begin the photosynthesis factory are chlorophyll, water and

carbon dioxide

A starch molecule is like a:

chemical battery reservoir of energy

The green chemical in plants which is needed to produce food is

chlorophyll

Oval shaped cells in a leaf which contain the green chemical are:

chloroplasts

A chemical which speeds up or helps organic chemicals to combine or break down is a(n)

enzyme

A plant leaf is as complex as a modern chemical _______________

factory

Which light grows the shortest plant?

green

The basic food of all animals and humans is ________________

green plants

A particular group of plants which can "manufacture" their own fertilizer is known as

legumes

What does the sun supply to a leaf?

light energy

Which light grows the tallest plant?

red

Which light produces the most glucose in the plant? (remember from the previous lesson that glucose is a food product (sugar) made during photosynthesis in a plant.)

red

The plant food which is made by photosynthesis is called

starch

Fertilizers which are "factory-made" for plants are called

synthetic

The main purpose of a leaf is:

to make plant food

Choose the reason(s) why plants need fertilizer. (There may be more than one answer.)

to provide nitrogen for proteins to provide various minerals
