Plant Transport and Photosynthesis Concepts

What are the simple compound inorganic sources plants use to prepare their own food?

• Carbon dioxide

• Water

• Both carbon dioxide and water

• Sunlight

Which of the following raw materials do plants absorb from the soil to build their bodies?

• Nitrogen

• Phosphorus

• Soil

• All of the above

How do plants absorb raw materials from the soil?

• Through their leaves

• Through their stems

• With the help of roots

• Through their flowers

Why do tall trees require a proper transport system?

• They have large dead cells

• Raw materials cannot diffuse easily over large distances

• They have low energy needs

• They do not move

What do plants need for photosynthesis and survival?

• Water

• Mineral salts

• Raw materials (CO2)

• All of the above

Which plant tissue is responsible for transporting water and mineral salts from the roots to other parts of the plant?

• Phloem

• Xylem

• Stomata

• Chlorophyll

Which plant tissue is responsible for transporting the products of photosynthesis (food) from the leaves to other parts of the plant?

• Xylem

• Sieve elements and companion cells

• Parenchyma and collenchyma

• Epidermis and cortex

What is the process by which plants lose water in the form of vapor from their aerial parts into the atmosphere?

• Absorption

• Transpiration

• Photosynthesis

• Respiration

What is the term for the transport of soluble products of photosynthesis throughout the plant?
