Flowers Flashcards
Vascular:
(TALLER) Conduct food and water throughout theirs structure
Nonvascular:
(SHORTER) lack special tissue for conducting water or food.(No seeds)
Angiosperms:
Produce flowers
Gymnosperms:
seeds, NO FLOWErs, woody, cones
Annuals:
Single growing season
Biennial:
Two growing seasons
Perennials:
Grow year after year
Flower:
reproductive organ
Sepals:
cover petals
Petals are brightly colored to…
attract insects
Pedicel:
supports the flower
Pistil:
Female structure (stigma, style, ovary, ovules
Stigma:
Sticky surface that attracts pollen grains
Style:
large vase-like structure which encloses ovary
Ovary:
Hollow, bulb-shaped structure in style which hold ovules
Ovules:
Small, round cases inside ovary which contain egg cells and turn into seeds when egg is fertilized
Stamen:
Male Structure (Anther on top of filament)
Tube Nucleus:
portion of pollen grain cells that pave the Pollen Tube
Sperm Nuclei:
The two sperm nuclei that follow the Tube Nucleus. One fertilizes and the other forms endosperm which feed embryo
Endosperm:
Food supply for a newly fertilized seed formed by two nuclei polar nuclei
Pollen Tube:
burrow produced by the TUBE NUCLEUS so that sperm nuclei can reach the ovule
Shoot Apex:
The tip of the stem in plants which is composed of meristem tissue which is capable of quick growth
Terminal Bud:
The beginning of a new set of leaves
Fruit:
Matured Ovary which contains seeds (provides protection and as well as method to disperse them)
Seeds:
Tiny embryonic plants, stored food, and coat of protection
Germination:
The initial sprouting and growing of plants, Requires correct moisture, temp, and oxygen.
Simple fruits:
Formed from single ripened ovary
Compound fruits:
(Apple) Aggregate fruit or multiple fruit. Develop from many separate ovaries
Aggregate fruit:
Many ovaries of a single flower fuse together (raspberry)
Multiple Fruit:
(Pineapple, Strawberry) Forms from the fusing of several ovaries of separate flowers
Cotyledon:
Where stored food in seeds can be found
Dicots:
2 Cotyledons (oaks, flowers, vegetables) (leaves have branched or networked veins) (Flowers with petals in multiples of 4 or 5) (Vascular bundles are arranged in rings)(taproot system with smaller secondary roots)
Monocots:
1 Cotyledon (Grasses, lilies, palm trees) (leaves have parallel veins) (flowers with petals in multiples of 3) (Random vascular bundle arrangement) (Fibrous roots)
