Plant Vascular Tissue Functions

What vital substances are absorbed by plant roots from the soil?

• Glucose

• Oxygen

• Water and minerals

• Amino acids

What are the two main vascular tissues in plants that allow substances to move throughout the plant?

• Epidermis and Cortex

• Xylem and Phloem

• Pith and Cambium

• Root and Stem

What is the primary function of xylem tissue in plants?

• Transporting manufactured food

• Storing excess sugars

• Distributing water and minerals

• Providing structural support only

Which characteristic of some xylem parts allows water and minerals to pass through easily?

• They have thick cell walls

• They contain abundant protoplasm

• They lack protoplasm or cell walls

• They are made of living cells

What substance strengthens the cells of the xylem?

• Cellulose

• Pectin

• Lignin

• Starch

What does phloem tissue primarily transport in plants?

• Water and minerals

• Oxygen and carbon dioxide

• Manufactured foods like sugars and amino acids

• Soil nutrients

What is the process called when phloem transports manufactured foods from green parts of the plant to other parts?

• Transpiration

• Photosynthesis

• Respiration

• Translocation

What is a characteristic of a mature sieve tube cell?

• It has a thick nucleus

• It has a degenerated protoplasm

• It is filled with chloroplasts

• It has a rigid cell wall

Why does a sieve tube cell need a companion cell?

• To provide structural support

• To carry out its vital processes

• To store excess food

• To absorb water from the soil

In the roots of herbaceous dicot plants, how are xylem and phloem arranged?

• Xylem forms an X-shape in the middle, and phloem fills around it.

• Phloem forms an X-shape in the middle, and xylem fills around it.

• Both xylem and phloem are clustered into circular shapes at the edge.

• Xylem is positioned above the phloem in a vascular bundle.
