Photosynthesis Flashcards 1

Front

What are the 3 reactants of photosynthesis?

Back

carbon dioxide, sunlight, water

Answer explanation

Plants need three things for photosynthesis: carbon dioxide, sunlight, and water. They use these to make glucose, which is a type of sugar, and oxygen..

Front

What pigment captures/absorbs sunlight?

Back

chlorophyll

Answer explanation

Chlorophyll is the green pigment in plants that captures sunlight for photosynthesis. It mainly absorbs blue and red light, which helps turn solar energy into chemical energy.

What are the tiny openings that let in the carbon dioxide needed for photosynthesis?

Back

stomata

Answer explanation

The tiny openings that let carbon dioxide enter a plant for photosynthesis are called stomata. They are important for gas exchange. Xylem and phloem transport water and nutrients, while chloroplasts are where photosynthesis happens.

How does water travel from the roots to the plant leaf? Name the structure that carries water.

Back

stem (xylem)

Answer explanation

Water moves from the roots to the leaves through the stem. Xylem are special tubes in the plant stem that carry water and minerals upward. Other parts of the plant do not perform this function.

What are the 2 products of photosynthesis?

Back

oxygen, glucose

Answer explanation

Plants make two important products during photosynthesis: oxygen and glucose. In this process, they use sunlight, carbon dioxide, and water to create glucose for energy. They also release oxygen as a byproduct.

What is the main purpose of photosynthesis?

Back

To make food

Answer explanation

The main purpose of photosynthesis is to make food for plants by converting sunlight, carbon dioxide, and water into glucose. While it also releases oxygen and absorbs sunlight, the primary goal is food production.

Front

Which product is "waste" or a "by-product" and mostly released by the producer (plant)?

Back

oxygen

Answer explanation

Plants produce oxygen as a result of photosynthesis, and they release it into the air. At the same time, they take in carbon dioxide. Instead of being waste, plants make sugar and glucose for energy.

Front

How does oxygen get released by the producer (plant)? Name the structure in the leaf.

Back

stomata

Answer explanation

Plants release oxygen during photosynthesis through small openings called stomata. These openings let gas exchange happen, allowing oxygen to leave the leaf and enter the atmosphere.

Front

What are the reactants (what is needed) for photosynthesis?

Back

light, water, and carbon dioxide

Answer explanation

Photosynthesis needs light, water, and carbon dioxide to make glucose and oxygen. The correct ingredients are light, water, and carbon dioxide, which makes this the right choice.

Which part of the plant cell (organelle) is responsible for making food (Glucose) using sunlight?

Back

Chloroplast

Answer explanation

The chloroplast is a part of plant cells that changes sunlight into energy through photosynthesis. This process creates glucose, which serves as food for plants. It is important for their growth and energy.
