Biology Unit 4

Front

What is the function of phloem in plants?

Back

Phloem is the plant tissue responsible for transporting the products of photosynthesis, such as sugars, from the leaves to other parts of the plant, including stems and roots.

Front

What pigment gives plants their green color?

Back

Chlorophyll is the pigment that causes plants to appear green, as it absorbs light energy for photosynthesis.

Front

What is the role of stomata in plants?

Back

Stomata are small openings on the surfaces of leaves that allow for gas exchange, enabling the intake of carbon dioxide and the release of oxygen during photosynthesis.

Front

Where do plants primarily absorb water and minerals?

Back

Plants primarily absorb water and certain mineral nutrients through their roots.

Front

What is the process by which plants convert sunlight into usable energy?

Back

Photosynthesis is the process by which plants capture radiant energy from sunlight and convert it into chemical energy in the form of sugar.

Front

What is the primary product of photosynthesis?

Back

The primary product of photosynthesis is sugar (glucose), which serves as an energy source for the plant.

Front

What is the difference between xylem and phloem?

Back

Xylem transports water and minerals from the roots to the leaves, while phloem transports the products of photosynthesis from the leaves to other parts of the plant.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily from the sun, which is essential for the process of photosynthesis.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin cycle).

Front

What is the significance of the root system in plants?

Back

The root system anchors the plant in the soil, absorbs water and nutrients, and stores energy.
