1B Flashcards
What is the primary function of roots in plants?
To anchor the plant and absorb water and nutrients from the soil.
True or False: The root system is responsible for photosynthesis.
False
What are nodes in a plant?
Points on the stem where leaves and buds are attached.
Fill in the blank: The segments of a stem between two nodes are called __________.
internodes
What is the terminal bud?
The bud located at the tip of a stem that is responsible for growth in length.
What is the role of the axillary bud?
To produce new shoots or branches in the leaf axil.
What is apical dominance?
The phenomenon where the terminal bud inhibits the growth of axillary buds.
True or False: Rhizomes are a type of underground stem.
True
Which part of the plant typically exhibits apical dominance?
The terminal bud.
What is a characteristic of rhizomes?
They can store nutrients and allow for vegetative reproduction.
Multiple Choice: Which of the following is NOT a function of roots? A) Water absorption B) Nutrient storage C) Photosynthesis D) Stability
C) Photosynthesis
How do nodes differ from internodes?
Nodes are points of attachment for leaves and buds, while internodes are the segments between them.
What can trigger the growth of axillary buds?
Removal of the terminal bud, which reduces apical dominance.
Fill in the blank: The growth of a plant is primarily concentrated at the __________.
terminal bud
What type of plant structure is a rhizome considered?
A modified stem.
Multiple Choice: Which structure is responsible for lateral growth in plants? A) Terminal bud B) Axillary bud C) Node D) Internode
B) Axillary bud
What happens to axillary buds when apical dominance is removed?
They are allowed to grow and develop into new branches.
What is the main difference between a terminal bud and an axillary bud?
A terminal bud is at the tip of the stem, while an axillary bud is found in the leaf axil.
Fill in the blank: The __________ system can include both fibrous and taproot structures.
root
What is the significance of nodes in plant growth?
They are sites for leaf and bud development, influencing overall plant architecture.
