At the tips of roots and shoots
What type of growth involves an increase in thickness of the stem and root?
Diffuse secondary growth
Which part of the plant contains primary tissues?
Primary plant body
What initiates primary growth in a plant?
Apical meristems
In which plants does specialized secondary growth involve the production of additional parenchymatous elements?
Monocotyledons like palms
What type of growth may involve cells of the ground tissue not localized in a specific region?
Diffuse secondary growth
How do palm trees primarily increase their thickness near the apex?
Through primary thickening meristem activity
What type of meristem gives rise to the ground tissue system?
Ground meristem
Which type of meristem is responsible for secondary growth in woody stems and roots?
Lateral meristem
What does the vascular cambium give rise to?
Secondary xylem and phloem
Which type of cambium is responsible for producing the outer bark in woody plants?
Cork cambium
What is the main function of stomata in plants?
Opening and closing pores based on environmental conditions
What is the main function of lateral meristems?
Produce the secondary plant body
Which part of the plant contains subsidiary cells surrounding stomata?
Guard cells
What is the outcome of secondary growth in plants?
Increase in girth or diameter
What is the role of bulliform cells in leaves of grasses?
Conserving water by causing leaf rolling
Which plant structures serve to protect and prevent evaporation of water?
Trichomes
In what situation do bulliform cells lose water and cause a leaf to roll into a protected cylinder?
In hot and dry conditions
What is the function of specialized cells called subsidiary cells?
Act as reservoirs for water and ions
What is the main function of collenchyma cells?
Providing flexible support for organs
How do collenchyma cells differ from parenchyma cells?
Having unevenly thickened cell walls
Where are collenchyma cells usually located in plants?
Under the epidermis of leaves, stems, and roots
What is a key characteristic of sclerenchyma cells that distinguishes them from collenchyma cells?
Lacking protoplasts at maturity
Why are collenchyma cells able to provide support without restricting growth?
Because they have thick walls but lack lignin
In what plant parts can you find sclerenchyma cells?
Throughout both primary and secondary plant body
