What process do plants use to create their own food?

Plants use photosynthesis to create food.

• Converts sunlight into energy.

• Uses water and carbon dioxide.

• Produces glucose for growth.

Plants are essential for the survival of all living organisms because they produce ___, which provides energy.

Glucose

True or False: Plants only provide food for themselves and do not contribute to the food chain.

False. Plants are the foundation of the food chain and provide energy for animals that consume them.

I am produced when plants convert sunlight, water, and carbon dioxide into energy. What am I?

Glucose

Fill in the blank: Plants recycle air by producing ___, which is essential for all living things to breathe.

Oxygen

What is the significance of the oxygen produced during photosynthesis?

The oxygen produced during photosynthesis is vital for all living organisms as it is essential for respiration.

Which components do plants combine during photosynthesis to create their food?

Plants combine water and carbon dioxide using sunlight during photosynthesis to create glucose.

Riddle: I help feed the world and clean the air, using sunlight without a care. What am I?

A plant

What role do plants play in the ecosystem aside from providing food?

Plants play a vital role in recycling air by producing oxygen, which is essential for the survival of living organisms.

What is the primary role of chlorophyll in photosynthesis?

Chlorophyll captures sunlight energy, which is essential for driving the chemical reactions of photosynthesis.

Photosynthesis occurs mainly in the ___ of plants.

Leaves

True or False: Oxygen is a raw material for glucose production during photosynthesis.

False. Oxygen is a byproduct released during photosynthesis, while carbon dioxide is the raw material used to produce glucose.

Riddle: I am a green pigment that plants need to capture sunlight. What am I?

Chlorophyll

What essential role does water play in the process of photosynthesis?

Water is vital for photosynthesis.

• Facilitates chemical reactions.

• Transports nutrients and sugars.

• Provides structural support.

Fill in the blank: Plants store food as ___ in various parts such as leaves and roots.

Starch

What are the five key components required for photosynthesis?

Chlorophyll, sunlight, water, carbon dioxide, and soil.

During photosynthesis, what happens to water molecules when chlorophyll absorbs sunlight energy?

Sunlight energy splits water molecules into hydrogen and oxygen.

What is the primary product of photosynthesis that is converted into starch for storage in plants?

Glucose is the primary product of photosynthesis that is converted into starch for storage in plants.

Different parts of plants serve as food for animals. List the food sources for the following parts: leaves, roots, and seeds.

Leaves: cabbage, lettuce; Roots: carrots, potatoes; Seeds: sunflower seeds, hazelnuts, mealies.

Fill in the blank: The iodine starch test is used to identify starch; it turns ___ if starch is present.

Blue-black

True or False: Starch is a simple molecule that provides quick energy like glucose.

False. Starch is a complex molecule made of many glucose units and is used for long-term energy storage.

Riddle: I am a complex molecule made of many glucose units, less sweet than sugar, and used for long-term energy storage. What am I?

I am starch.

What is the difference between starch and sugar in terms of their molecular structure and energy provision?

Starch stores energy; sugars provide it.

• Sugars are simple molecules.

• Starch consists of glucose units.

• Sugars offer quick energy sources.

Fill in the blank: Plants convert glucose into starch, which is stored in various parts such as ___ for mealies and ___ for rice.

Seeds

List three examples of fruits that are commonly consumed by animals.

Apples, bananas, and peaches are examples of fruits that are consumed by animals.
