annual plants
one growing seasons
3 typical functions of stem
support and elevation of the shoot system, transportation of the products of photosynthesis, transportation of minerals and water from different parts of the plant
stilts roots arise from what part of the plant?
base of the stem
it is a root of a parasitic plant that penetrates a hosts’ tissue and absorbs nutrients and minerals
haustorial plants
a ____ is a modified stem grows horizontally underground.
rhizome.
function of rhizomes, bulbs, tubbers, and corm
storage
kataka-taka
reproduction
where is the common habitat of pneumatophore roots
often near thee coastlines
poinsettia
modified leaves, but they dont have the bright color: depending on the season
what are typical parts of a typical plant?
roots, flowers, leaves, stem, fruits
part of the stem that leaves arises
nodes
ginger: structure & functions
rhizomes
modified stem grows
horizontally/parallel to the ground
what will happened in the second growing season of biennial plants
you will only see the normal roots, not the enlarged roots for the stored food will be utilized by the plant
how call you tell if the plant is a modified stem?
has nodes and internodes
relatively compressed/solid stem, has fleshy leaves
corm
reproduction in plants
maybe asexual and sexual
give the aerial modified stems
tendrils, stolon, thorns
typical stem grows
vertically/perpendicullar to the ground
grapes: structure & functions
tendrils, support
runners are creeping stems with long internodes, grows horizontally above ground
stolon
it also has something to do with pant modification
mutation of genes
spikey, tapered
thorns
describe what is a typical plant?
a typical plant is a plant with its usual structure and functions you typically see.
jackfruits: structure & functions
buttress roots, support
what is the common function of haustorial plants
parasitic plant absorbs nutrient/mineral of the host plant
white gabi: structure & functions
corm
arise as a swollen end of stolons
tubers
what makes a plant be modified or like have a specialization?
because of threats from its environment. e.g. humidity / presence of herbivores. in order to adapt to their environment
what is the characteristic of life that evident in plant modification?
adaptation to the environment
vegetative propagation, another term
asexual reproduction
onion: structure & functions
bulb
what is the element that aerial epiphytic plants absorbs?
oxygen
what is a twinners?
the stem is the one who coils/wraps in a pole or any supporting material.
what is modified plant?
a modified plant is where a plant have a modification/specialization in order to survive in the environment its in.
what are the typical part of a root system?
root
potatoes: structure & functions
tubers
sugarcane: structure & function
stilt roots, mechnical support
state the six modified root structures
stilt root/prop roots, pneumatophores, haustorial roots, buttress roots, aerial epiphytic roots, fleshy and enlarged roots

thorns, protection
what are the typical parts of a shoot system?
fruits, flowers, leaves, stem
explain how does plant has a ecological importance.
one of a plants typical function is anchorage of the plant to the ground and absorption of water and minerals. this helps lessen the destruction of floods and landslide.
carrots, beets, radishes :function and structure
fleshy and enlarged roots, storage of starch and water
region between a node and another node
internodes
does plants need watering everyday?

facilitates aeration or to obtain oxygen necessary for respiration
pneumatophores
state the seven modified functions of a stem
rhizomes, tendrils, thorns, reproduction, tuber, corm, bulb
