Module 14: Kingdom Plantae: Anatomy and Classification Flashcards
if a portion of a plant is producing new cells, what type of plant tissue will be in the region
meristematic tissue
what do we call the structure that attaches the blade of the leaf to the stem
the petiole
in a leaf, what is the function of the palisade mesophyll
photosynthesis
in a leaf, what is the function of the spongy mesophyll
photosynthesis
in a leaf, what is the function of the epidermis
protection
in a leaf, what is the function of the xylem
transports water and minerals
in a leaf, what is the function of the phloem
transports food and organic substances
in a leaf, what is the function of the chollenchyma
support
what controls the opening and closing of the stomata on a leaf
the guard cells
why is the bottom of a leaf typically a lighter shade of green than the top of the leaf
the spongy mesophyll is on the bottom of the leaf and is a lighter shade of green
name two types of pigments that cause leaves to be a color other than green
carotenoids and 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
root cap
meristematic region
elongation region
maturation region
which region of a root contains undifferentiated cells
the meristematic region
what allows woody stems to have no limits to their growth, unlike herbaceous stems
the cork cambium
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 the most of the wood in a woody stem
xylem
what kind of vascular tissue is found in the inner bark of a woody stem
phloem
what is the dominant generation in the moss life cycle
gametophyte generation
a fern has antheridia and archegonia, which part of the fern life cycle is it in
gametophyte generation
why are plants from phylum Bryophyta relatively small
they have no vascular tissue
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
male: pollen cone
female: seed cone
what is the fundamental difference between monocots and dicots
the number of cotyledons produced in the seed
name a difference between monocots and dicots
monocots: venation is parallel
dicots: venation is netted
a plant produces flowers, which phylum does it belong to
anthophyta
the study of plants is called
botany
plants that grow year after year are
perennials
plants that live for only one year are
annuals
plants that live for two years are
biennials
what are the two types of plant organs
vegetative and reproductive
the primary portion of a leaf is called
the blade
the very tip of the blade is called
the apex
what structure in a deciduous tree causes the leaves to die and fall off in the autumn
the abscission layer
what are anthocyanins, and what do they do to a leaf’s color
a group of pigments that can give a leaf a color other than green
why is the bark of a tree often cracked
the stem grows and breaks the bark when it gets too big
if a plants has seed and pollen cones, which phylum does it belong to
phylum coniferophyta
