How are the xylem and phloem arranged in plants?

• As separate layers in the leaves

• As a series of interconnected tubes through the leaves, stems, and roots

• As a network around the plant's flowers

• As clusters in the fruit

What is the primary function of xylem in plants?

• To transport nutrients from the leaves to the roots

• To transport water and dissolved minerals from soil to leaves

• To produce food through photosynthesis

• To support the plant structure

In mature plants, what are xylem cells described as?

• Living cells that divide and grow

• Dead cells with only cell walls remaining, forming xylem vessels

• Cells that store nutrients

• Cells that transport sugars throughout the plant

What are the components of xylem vessels referred to as?

• Chloroplasts and mitochondria

• Stomata and guard cells

• Tracheids or vessel elements

• Phloem fibers and sieve tubes

What is the primary function of phloem as described in the text?

• To transport water from roots to leaves

• To transport sugars produced during photosynthesis from leaves to roots

• To provide structural support to the plant

• To absorb nutrients from the soil

What are the phloem vessels primarily composed of?

• Xylem cells

• Sieve tubes and companion cells

• Chloroplasts

• Root hairs

What characteristic of phloem vessels allows the sugary sap to flow through them?

• The presence of chlorophyll

• The rigidity of the cell walls

• The porous cell walls

• The waterproof nature of the cells

What is the role of companion cells in the phloem vessels?

• They conduct water

• They store chlorophyll

• They offer support to sieve tube cells

• They absorb sunlight
