To conduct photosynthesis
None
12.
What distinguishes tracheids from vessel elements in xylem tissue?
Topic:
plant Tissues
Tracheids are shorter and wider than vessel elements.
Tracheids are longer and narrower than vessel elements.
Tracheids conduct food, while vessel elements conduct water.

None
18.
How do sclerenchyma fibres differ from parenchyma cells in terms of structure and function?
Topic:
plant Tissues
Sclerenchyma fibres are living and flexible, while parenchyma cells are dead and rigid.
Sclerenchyma fibres are dead and provide structural support, while parenchyma cells are living and involved in storage and photosynthesis.
Both are involved in nutrient transport.
Both are primarily responsible for growth.
None

Goblet cells secrete mucus that traps particles and lubricates surfaces.
Goblet cells absorb nutrients.
Goblet cells provide structural support.
None
22.
What is the significance of the stratification in stratified squamous epithelium?
Topic:
