Chapter 22 A Flashcards
What are vegetative parts of land plants?
The nonrepeoductive part of plant
What are the three vegetative plant organs?
stem, leaves, and roots.
What are the functions of the stem, leaves, and roots?
stem: supports the leaves
leaves: Reproduce sucrose by photosynthesis
roots: Aborbs water/minerals
What are the two main parts of a leaf?
blade and the petiole.
What are the shoot system and roots system?
The shoot system: Everything above the soil
the root system: Everything in the soil
What are two functions of the shoot system?
photosynthesis and reproduction
What are two functions of the root system?
uptake of water and nutrients
support
What are the functions of terminal buds and axillary buds?
terminal buds: a site of future primary growth
axillary buds: a site of future secondary growth
What are nodes and internodes?
Nodes are points on the stem where leaves are attached
internodes are the segments between nodes.
What are fruits?
Rippened ovaries/anything that contain seeds.
What are primary growth and secondary growth?
Primary growth: growth from the vertical direction
secondary growth: Growth in horizontal direction
What are herbaceous plants and woody plants?
Herbaceous plants: plants with green soft stems
woody plants: plants with stem/root made of wood
What are the three plant tissues?
dermal tissue
vascular tissue
ground tissue
What are two functions of each tissue?
Dermal tissue: protection and regulates gas exchange
vascular tissue: transports water and sugars (organic material)
ground tissue: provides support and storage.
What are the cuticle, stomata, and guard cells?
a waxy layer that coats stems and leaves preventing water loss
Allows gases to be moved in and out
regulates the opening of the stomata.
What are the two types of vascular tissue?
xylem and phloem.
What are the general functions of each vascular tissue?
Xylem transports water up
phloem transports organic material upand down
What are the two categories of plant cells?
conducting cells and non-conducting cells
What are the three general nonconducting plant cells?
parenchyma, collenchyma, and sclerenchyma.
What are the functions of parenchyma, collenchyma, and sclerenchyma?
Parenchyma cells are basic plant cell
collenchyma cells provide flexible support
sclerenchyma cells offer mechanical support
What are the four conducting plant cells?
tracheids, vessel elements, sieve tube elements, and companion cells.
What are sieve plates?
porous area at the end of a sieve tube element.
