Study Set Content:
Most are modifications of the leaf, much of the normal leaf tissue is replaced with?
sclerenchyma
Woody plant-stipules at the bases of the leaves that are modified as the
short, paired spines
barrel cactus(Ferrocactus)
(Ferrocactus)
spinelike objects arising in the axils of leaves of woody plants are modified stems rather than modified leaves
Thorns
roses and raspberries, neither leaves nor stems, outgrowths from the epidermis or cortex
Prickles
Large, thin-walled parenchyma cells without chloroplasts to the interior or chlorenchyma tissue just beneath the epidermis. Non-photosynthetic cells contain large vacuoles that can store relatively substantial amounts of water
Storage Leaves
The fleshy leaves of onion, lily and other bulbs store large amount of what to be used by plant for rapid growth early in the subsequent growing season.
carbohydrates
Christmas flower
poinsettia
Floral Leaves aka
Bracts
Found at the bases of the flowers or flower stalks
Floral Leaves
in the poinsettia flowers themselves have no
petals
but the brightly colored what surrounds the flowers function as petals attracting pollinators
Floral bracts
Almost 200 species of flowering plants are known to have these leaves
Insect-Trapping Leaves
Certain elements particularly (blank) may be deficient in the soil, or they may be in the form not readily available to plants
Nitrogen
grow in swampy areas and bogs of tropical temperate regions
Insectivorous plants
Insect-Trapping Leaves can develop normally without insects given that
they are provided with the proper nutrients
All the plants have chlorophyll and are able to make their own food
Insect-Trapping Leaves
Pitcher plants nectar secreting glands
give distinctive odor
Flattened, larger, cone-shaped, vaselike, umbrella-like flaps
Pitcher plants
Tiny measuring 2.5 to 5.0 cm in diameter, Covered with up to 200 upright, glandular hairs, that look like miniature clubs
Sundews
