Introduction to Plant Tissues
What are plant tissues?
Answer: Groups of cells that work together to perform specific functions
Where are apical meristems found in plants?
Answer: At the tips of roots and shoots.
Which simple permanent tissue stores nutrients in plants?
Answer: Parenchyma.
What is the primary function of xylem in plants?
Transport water and minerals.
Which tissue in plants is primarily responsible for storage?
Parenchyma.
Name the two main types of plant tissues.
Answer: Meristematic tissues and permanent tissues
What type of growth do apical meristems promote?
Lengthwise growth (primary growth).
What is the main function of collenchyma tissue?
Answer: Provides flexible support to growing parts of the plant.
What is the main function of phloem in plants?
Answer: Transport food (sugar) throughout the plant.
Which tissue provides mechanical strength to plants?
Sclerenchyma.
Which type of tissue is responsible for plant growth?
Meristematic tissue.
Which meristematic tissue is responsible for the plant's thickness growth?
Lateral meristem.
Name the simple permanent tissue that is thick-walled and provides rigidity.
Sclerenchyma.
Name the two types of cells found in xylem.
Vessels and tracheids.
What tissue is responsible for transporting water upwards in plants?
Xylem
What is the main function of permanent tissues in plants?
Answer: Perform specific, mature functions in the plant.
What type of meristematic tissue helps in regrowth after cutting or grazing?
Intercalary meristem.
Which simple permanent tissue is involved in photosynthesis?
Parenchyma.
Which complex tissue contains sieve tubes?
Answer: Phloem.
What tissue transports food in both directions (up and down) in plants?
Phloem
What is the key difference between meristematic and permanent tissues?
Answer: Meristematic tissues actively divide, while permanent tissues have matured and stopped dividing.
Name a type of plant that uses intercalary meristems for rapid growth
Grasses.
What makes sclerenchyma cells different from parenchyma cells?
Sclerenchyma cells are thick-walled and dead at maturity, while parenchyma cells are thin-walled and living.
Name two components of phloem tissue.
Sieve tubes and companion cells.
Which two tissues are responsible for transporting materials in plants?
Xylem and phloem.
