Study
1
Question
What are the two main plant organ systems?
Answer
Shoot system and root system
2
Question
What is the primary function of the shoot system?
Answer
Photosynthesis, reproduction, storage, transport, hormones
3
Question
What is the primary function of the root system?
Answer
Anchorage, absorption, storage, transport, hormones
4
Question
Where does secondary growth occur and what does it produce?
Answer
In lateral meristems (vascular cambium and cork cambium); produces bark and wood expansion
5
Question
What are the three tissue systems in plants?
Answer
Dermal, ground, and vascular tissues
6
Question
What tissue forms the epidermis in plants?
Answer
Dermal tissue (epidermis)
7
Question
What is the function of the dermal tissue?
Answer
Protects plant and controls gas exchange (via stomata)
8
Question
What are the three tissue types found in all plant organs?
Answer
Ground, vascular, and dermal tissues
9
Question
What is the role of parenchyma cells?
Answer
Ground tissue, metabolic functions, storage; alive at maturity
10
Question
What structures are part of the dermal tissue in leaves?
Answer
Epidermal cells, stomata, trichomes
11
Question
What type of tissues are xylem and phloem classified as?
Answer
Vascular tissue
12
Question
What is the difference between apical and lateral meristems?
Answer
Apical for primary growth (length); lateral for secondary growth (thickness)
13
Question
What is the primary plant tissue produced by protoderm?
Answer
Epidermis (dermal tissue)
14
Question
Which meristem gives rise to primary vascular tissue?
Answer
Procambium (in apical meristems)
15
Question
What type of meristem is responsible for secondary growth in woody plants?
Answer
Lateral meristems
16
Question
What cross-section organism is used to illustrate the root and stem sections in Basswood images?
Answer
Basswood root and stem cross-sections
17
Question
Name three simple plant tissues and a key characteristic for each.
Answer
Parenchyma – thin walls, living; Collenchyma – thickened walls, living; Sclerenchyma – thick walls, dead at maturity
18
Question
Which epidermal feature creates root hair extensions in plants?
Answer
Root hairs (epidermal extensions)
19
Question
In ground tissue, which cell type is primarily involved in photosynthesis and storage?
Answer
Parenchyma
20
Question
What is the general function of parenchyma cells in leaves and stems?
Answer
Photosynthesis, storage, and regeneration
21
Question
What is the primary role of sclerenchyma cells?
Answer
Rigid support and protection via thick secondary walls
22
Question
Name the three major plant tissue systems mentioned.
Answer
Dermal, Ground (parenchyma/collenchyma/sclerenchyma), Vascular (xylem/phloem)
23
Question
Which components make up the vascular tissue system?
Answer
Xylem and Phloem (with associated parenchyma, fibers, and rays)
24
Question
What conducts water in plants?
Answer
Xylem
25
Question
What conducts food (sugars) in plants?
Answer
Phloem
26
Question
In vascular bundles, which tissues are adjacent to each other in stems?
Answer
Xylem and Phloem
27
Question
What is the periderm composed of?
Answer
Cork and parenchyma
28
Question
Name secretory structures responsible for latex, resins, nectar, and related substances.
Answer
Secretory structures (latex, resins, nectar, other stored substances)
29
Question
What are secretory structures responsible for nectar production associated with?
Answer
Nectaries in flowers
30
Question
What is the role of trichomes in epidermis?
Answer
Protection, secretion, and sometimes absorption (as part of epidermal structures)
