Module 14 (vocabulary is on Biology ipad app) Flashcards
If a portion of a plant is producing new cells, what type of plant tissue will be in that region?
Meristematic tissue
See question on page 461, #4
a. Whorled
b. Alternate
c. Opposite
See question on page 461, #5
Letter: Shape: Margin: Venation:
a. Deltoid Entire Parallel
b. Elliptical Serrate Pinnate
c. Lobed Entire Pinnate
d. Cleft Dentate Palmate
e. Orbicular Undulate Pinnate (if confused see note in key)
f. Chordate Entire Pinnate
In a leaf, what is the function of the following tissues:
a. palisade mesophyll
b. spongy mesophyll
c. epidermis
d. xylem
e. phloem
f. chollenchyma
a. photosynthesis
b. photosynthesis
c. protection
d. transports water & minerals
e. transports food & organic substances
f. support
What controls the opening and closing of the stomata on a leaf?
The guard cells control the opening and closing of the stomata.
Why is the bottom of a leaf typically a lighter shade of green than the top of the leaf?
The spongy mesophyll is typically on the underside of the leaf, and it is usually a lighter shade of green due to the fact that the photosynthesis cells are not tightly packed there.
Name two types of pigments that cause leaves to be a color other than green.
Carotenoids & anthocyanins
If a tree has no abscission layer, will it be deciduous?
no
Where is the abscission layer?
between the stem and the petiole
Name the four regions of a root. Which region contains undifferentiated cells?
root cap, meristematic region, elongation region, maturation region; undifferentiated cells are in the meristematic region
See page 462, question #13
a. dicot
b. monocot
What allows woody stems to have no limits to their growth, unlike herbaceous stems?
the cork cambium can always produce more bark
What is the function of vascular cambium?
produces new vascular tissue
If a stem has cork cambium, is it woody or herbaceous?
woody
What kind of vascular tissue makes up most of the wood in a woody stem? What kind of vascular tissue is found in the inner bark of a woody stem?
xylem make up most of the wood in a woody stem, while phloem are found in the inner bark
What is the dominant generation in the moss life cycle? Is it haploid or diploid?
gametophyte generation; haploid
A fern has antheridia and archegonia. Which part of the fern life cycle is it in? Is this the dominant generatin?
gametophyte generation; not dominant for ferns
Why are plants from phylum Bryophyta relatively small?
Since plants from phylum Bryophyta have no vascular tissue, there is no efficient way to transport nutrients throughout the plant.
If a 15-foot tall plant has a root system that goes four feet deep, is it a fibrous or taproot system?
fibrous
What are the male and female reproductive organs in a tree from phylum Coniferophyta?
female is the seed cone; male is pollen cone
What is the fundamental difference between monocots and dicots?
the number of cotyledons produced in the seed
Name another difference between monocots and dicots.
in monocots the venation is parallel, while it is netted in dicots; the fibrovascular bundles are packaged differently in monocots and dicots; typically, monocots have fibrous root systems whereas dicots have taproot systems; finally, monocots usually produce flowers in groups of three or six while dicots produce flowers in groups of four or five (only need to list one)
A plant produces seed cones and pollen cones. Is it vascular? To what phylum (of the ones that we discussed) does it belong?
Coniferophyta
A plant produces flowers. To what phylum does it belong?
Anthophyta
What do we call the structure that attaches that blade of the leaf to the stem?
the petiole
