Photosynthesis

These flashcards cover key concepts related to photosynthesis, including its requirements, products, and related processes.

What are the main requirements for photosynthesis?

Chlorophyll, sunlight, carbon dioxide, and water.

What is the equation for photosynthesis?

Carbon dioxide + water (chlorophyll)→ glucose + oxygen.

What do plants store glucose as?

Plants convert glucose into starch for storage.

What is the primary pigment involved in photosynthesis?

Chlorophyll.

Why do plants need to store glucose?

To reserve energy for later use and maintain function during non-photosynthetic periods.

What happens to glucose in plants after photosynthesis?

It can be used for energy, stored as starch, or converted into other compounds.

How can you test if a plant has photosynthesized?

By checking for the presence of starch using iodine, which turns blue-black in its presence.

Where else besides leaves can starch be stored in plants?

Stems, roots, and fruit.

What are two other compounds that glucose can be converted into apart from starch?

Cellulose + other chemical compounds necessary for plant processes.

What type of energy do plants convert sunlight into during photosynthesis?

Chemical potential energy.

What process do living organisms use to release stored energy from food?

Respiration.

Photosynthesis occurs in the of plant cells.

chloroplasts.

The process of is essential for plants to convert sunlight into energy.

photosynthesis.

During photosynthesis, plants take in from the atmosphere.

carbon dioxide.

Chlorophyll is the pigment that makes plants and helps them absorb light energy.

green.

Glucose is converted into in plants for long-term energy storage.

starch.

What is the process by which plants synthesize their food using sunlight called?

Photosynthesis.

What is the byproduct of photosynthesis that is essential for animal life?

Oxygen.

What role does chlorophyll play in photosynthesis?

It helps absorb light energy.

Which two elements combine during photosynthesis to form glucose?

Carbon dioxide and water.

What is the form in which plants primarily store energy derived from glucose?

Starch.

What is the carbohydrate classification of glucose?

Glucose is classified as a simple sugar or monosaccharide.

What type of carbohydrate is starch?

Starch is a complex carbohydrate or polysaccharide.

How does the solubility of glucose compare to that of starch?

Glucose is soluble in water, while starch is not soluble.

What are the storage forms of energy in plants?

Glucose serves as a quick energy source, while starch serves as a long-term energy storage.

What is the taste of glucose compared to starch?

Glucose has a sweet taste, while starch is tasteless

How is glucose used as a basic molecule to make other compounds in plants?

Glucose can be converted into various compounds such as cellulose for cell structure, and other organic molecules necessary for plant processes, including amino acids and nucleotides.
