First plants that came on the scene 425 million years ago | Mosses, Liverworts, and Horsetails |
How is the Plant Kingdom divided? | Plants that produce seeds, and plants that don't produce seeds |
Angiosperm | Flowering Plant |
Monocots | Plants that produce seeds with one food part (cotyledon); leaves have parallel veins |
Dicots | Plants that produce seeds with two food part s(cotyledons); leaves have branching veins |
Gymnosperms | Plants that produce exposed seeds, usually on cones; have no flowers; most have needles for leaves and are evergreen |
Pines, Spruces, Junipers, Firs, and other Conifers, Yews, and Gingkos | Gymnosperms |
Where a Plant Produces Food | Leaves |
Chlorophyll | Green substance that captures energy from the sun |
Transpiration | Plants sweat by transporting water from the roots and release water vapor on the bottom side of the leaves |
Support System and Food & Water Highway for a Plant | Stem |
Xylem | In a plant, water and minerals from the soil are transferred upward from the roots through the _____________, |
Phloem | In a plant, food made in the leaves is transported through the _____________, |
Capillary Action | Pumping water and minerals in xylem and phloem plant tissues |
Tuber | Plants that have an underground storage site (potato) |
3 Functions of Roots | Anchors the plant, absorbs water and minerals in soil, and provides storage of sugars and and starches to roots for storage |
Root Foods People Eat | Carrots, Beets, and Radishes |
Woody Plants | Trees, shrubs, etc. |
Nonwoody Plants | Herbaceous plants that have green stems |
Most plants reproduce by ________. | Seeds |
Plant Seeds | Fertilized ovules (plant "eggs") from which new plants grow |
Germinate | Start growing |
Conifers | Make seeds in cones |
2 types of cones made by Conifers | Male (contain pollen) and Female (contain ovules) |
Pollination | Formation of pollen in a plant |
Fertilization | When the male plant pollen fertilizes the female plant ovules |
Plant Embryo | Fertilized plant ovules |
Stamen | Male part of a flower |
Carpel | Female part of a flower |
Perfect Flowers | Flowering Plants that have both a Stamen and Carpel |
Imperfect Flowers | Flowering Plants that have separate Stamen flowers and Carpel flowers |
Pollen | Produced in the "male" stamen of the flower |
Ovules | "Eggs" produced in the "female" ovary of the Carpel |
To fertilize the plant's ovules, the pollen travels from the stamen's _________ to the carpel's stigma, the flower part that catches the pollen. | Anther |
To fertilize the plant's ovules, the pollen travels from the stamen's anther to the carpel's __________, the flower part that catches the pollen. | Stigma |
After pollen grain lands on the stigma, it sprouts a tube that grows down inside the slender neck called the ______________ that connects the stigma to the ovary. | Style |
The fertilized ovule develops into a _________ containing a plant embryo. | Seed |
Not all plants reproduce by seeds. Some plants can regenerate from a plant _______, | Part |
Spores | Ferns, mosses, horsetails, and other seedless plants reproduce by ____________, |
What is the formula for photosynthesis? | Water + Carbon Dioxide -->Glucose + Oxygen + Water |
What is the formula for respiration? | Glucose + Oxygen --> Carbon Dioxide + Water + Energy |
Transpiration | Water evaporation from the underside of a plant's leaves |
Biomes | Large environments that share the same general climate of temperature and rainfall |
