Initial Assessment: Transport in Flowering Plants

Which part of the plant is primarily responsible for absorbing water and minerals from the soil?

• Leaves

• Stem

• Roots

• Flowers

What is the main force that helps water move up from the roots to the leaves in plants?

• Gravity

• Transpiration pull

• Osmosis

• Photosynthesis

The vascular tissue that transports water and minerals from the roots to the rest of the plant is called:

• Phloem

• Cambium

• Xylem

• Cortex

Which of these is NOT a function of the phloem?

• Transporting sugars from leaves to other parts of the plant

• Carrying water from the roots to the leaves

• Distributing nutrients throughout the plant

• Moving hormones

What part of the plant captures sunlight for photosynthesis?

• Roots

• Stem

• Leaves

• Flowers

Which of the following best describes the process of osmosis in plant cells?

• Movement of sugar in the phloem

• Movement of water from an area of high concentration to low concentration

• Movement of minerals into root hair cells

• Movement of carbon dioxide into leaves

Which part of the plant holds it up and supports the leaves?

• Roots

• Stem

• Flowers

• Seeds

What do plants need from the soil to help them grow?

• Sunlight

• Water

• Air

• Both water and minerals

What happens when there is an increase in the rate of transpiration?

• The plant wilts

• More water is pulled up from the roots

• Photosynthesis stops

• The plant grows faster

The main difference between xylem and phloem is:

• A. Xylem transports water, phloem transports sugars

• B. Xylem is dead at maturity, phloem is living

• C. Xylem is found in leaves, phloem in roots

• D. Both A and B
