typical plant and tissue Flashcards
define what is a typical plant
it is how a plant carries its usual function and structure we normally see.
how many organ system does a plant has
2
state the organ systems of a typical plant
shoot system
root system
carries photosynthesis
leaves
main function is the anchorage, support to the shoot system and storage of minerals and nutrients
roots system
aerial, above ground and consists of the organs: leaves, flowers, stem and fruits
shoot system
protect the seeds
fruits
carries reproduction of the plant
flower
plants have ecological value, why is that?
because they have given us benefits that dont require us to give money, (e.g. anchorage that causes to not flood and landslide)
support the plant and transport the products of photosynthesis
stem
absorption of minerals and nutrients
roots
male part of a flower and its parts
stamen: filament, anther
female part of a flower and its parts
pistil: ovary-ovule, style, stigma
the position of the plant is not vital for its function
false
arrange the following:
tissue, chemical level, cells with the same function, organ system, organs, cellular level
chemical level, cellular level, cells with the same function, tissue, organs, organ system
what is the part of a flower that when matured, turn into a fruit?
ovary
example of an animal that does seed dispersal? kopi luwak
palm civet
part of a stem which where new leaf arises
node
the area between a node and another node
internode
it is called the reproductive shoot
flower
called as vegetative shoot
stem, and leaves
give at least two benefits we can get from leaves
for cooking, oxygen(by means of photosynthesis),
give at least two benefits we can get from stem
firewood, construction material, paper, food
give at least two benefits we can get from flowers
can give relaxation, decorative purposes
give at least two benefits we can get from fruits
food, where we can get vitamins/minerals
give at least two benefits we can get from roots
elevate flooding and landslide, medical purposes
the primary parts of the roots
primary roots, secondary roots, tertiary roots
the entire plant body is derived from the product of photosynthesis
true
phloem transports these
amino acids, sucrose
xylem transports these
water and minerals
what is the substance in a xylem that helps the stem upright
lignin
all plants have flowers
false
pollen is transported from flower to another flower by which organisms? please that what(na ubusan nakoy questions)
pollinators: bees, birds, insects
how do flowers attract pollinators?
colorful petals
what protects the bud when flower if developing?
sepal
what pollinates the ovule?
pollen
type of maristematic tissue that is found in the tip of stems and roots and enables the plant to extend in length
apical meristems
type of maristematic tissue that is facilitates growth in thickness or girth in a maturing plants
lateral meristems
only in monocots, these types of maristematic tissue is found in the bases of leaf blades and at the nodes to increase length.
intercalary meristems
these plants that have soft and green stem. one growth for their lifetime- annual
herbaceous stem
these types of plants are stems that are covered with bark and its a perennial plant-has multiple growths season
woody stem
all plants starts in herbaceous stem
true
give rise to secondary xylem and phloem
vascular cambium
give rise to bark, cork or periderm. secondary growth in the epidermis of roots
cork cambium
still in the herbaceous phase, a skin of a young plant is covered by?
epidermis
by the time for the secondary growth the epidermis is replaced by?
periderm
surface of the plant that produce bark on stems and roots
periderm tissue
thin layer of cell covering all non-woody surfaces of the plant
epidermal tissue
in leaves, epidermis is covered by what? it helps the plant retain water and contain pores
cuticle
whose guard cells regulate gas exchange between plant and the environment by controlling the size of the stomata openings. even water vapor during transpiration
stomata
generally a single layer of cells
epidermis
multi-layered tissue, consists of phellem, phelloderm, and phellogen
periderm
protects the plant from pathogens, injury, prevents excesses water loss, and insulates the plant.
periderm
non living cells that cover the outside of stems and roots to protect and provide insulation for the plant
cork cells
transport system in shoots and roots
vascular tissue
does permanent tissue came from meristem?
true
these tissues are capable of cell division
meristems
tissues where is the site for photosynthesis, provides a supporting matrix for the vascular tissue, helps store water and sugars
ground tissue
component tissues of dermal tissue
epidermis and periderm
component tissue of ground tissue
parenchyma, collenchyma, sclerenchyma
component tissue of vascular tissue
xylem and phloem
upward direction transportation of water + minerals
xylem
two way flow direction of food transportation
phloem
in stems xylem and phloem is called
vascular bundle
in roots xylem and phloem is called
vascular stele/vascular cylinder
acts of filler tissue, synthesize organic compounds and provides support to the plant
ground tissue
type of ground tissue that carry out photosynthesis and storage
parenchyma
type of ground tissue that provides flexibility
collenchyma
type of ground tissue that provides support and strength
sclerenchyma
type of ground tissue that surrounds the fruits, storing the sweetness
parenchyma
collenchyma is irregular thickened at corners by
pectin
sclerenchyma has thickened cell walls made of?
cellulose
single layer of tightly packed cells that covers and protects plants
dermal tissue
