1.1 Flashcards
What is the primary function of plant tissues?
To perform specific functions that support the plant’s growth, development, and survival.
Name the two main types of plant tissues.
Meristematic tissue and permanent tissue.
True or False: Meristematic tissues are responsible for the growth of plants.
True.
Fill in the blank: Permanent tissues are derived from __________ tissues.
Meristematic.
What are the three types of permanent tissues?
Epidermal tissues, Ground tissues, and vascular tissues.
What is the main characteristic of parenchyma tissue?
Thinnest cell walls, always in turgid state. Involed in photosynthesis, repaid and regenation of plant tissues.
Which tissue is primarily involved in photosynthesis?
Parenchyma
Multiple Choice: Which of the following is NOT a type of simple permanent tissue? A) Parenchyma B) Collenchyma C) Sclerenchyma D) Xylem
D) Xylem.
What is the function of collenchyma tissue?
To provide mechanical support and elasticity to young and growing parts of the plant.
True or False: Sclerenchyma cells are dead at maturity.
True.
What are the two types of vascular tissues?
Xylem and phloem.
What is the primary function of xylem?
To transport water and minerals from the roots to other parts of the plant.
Fill in the blank: Phloem is responsible for the transport of __________.
Sugars and nutrients.
What are the main components of xylem tissue?
Cell wall contains lignin. consist of xylem vessel that are elongated, hollow and connect to each other from its root to the leaves
Multiple Choice: Which cell type in phloem is responsible for transporting sugars? A) Sieve tube elements B) Companion cells C) Both A and B D) None of the above
C) Both A and B.
What role do companion cells play in phloem?
They assist in the transport of nutrients and support the metabolic functions of sieve tube elements.
True or False: Vascular tissues are responsible for the transport of water and nutrients in plants.
True.
What is the difference between primary and secondary growth in plants?
Primary growth increases the length of the plant, while secondary growth increases the thickness.
What is the role of cambium in plants?
Cambium is responsible for secondary growth and produces new xylem and phloem.
What type of tissue forms the outer protective layer of the plant?
Epidermal tissue.
Fill in the blank: The __________ is a waxy layer that reduces water loss in plants.
Cuticle.
Multiple Choice: Which plant tissue is involved in the transport of water? A) Phloem B) Xylem C) Parenchyma D) Collenchyma
B) Xylem.
What is the purpose of meristematic tissue?
To enable continuous growth and cell division in plants.
True or False: All plant tissues originate from meristematic tissues.
True.
What is the main characteristic of sclerenchyma cells?
They have thickest walls that provide support and mechanical strength.
How does the structure of xylem contribute to its function?
Xylem vessels are hollow and have thick walls, allowing efficient water transport.
