science test 1
Xylem
transports water and dissolved minerals from the roots to the leaves.
Photosynthesis
is the process by which green plants use chemicals from the environment and energy from the sun to make their own food
Pollination
is the transfer of pollen from the anther to the stigma
After pollination
a pollen tube grows from a cell in the pollen grain
Multiple
Multiple fruit has many single fruits growing close together
Phloem
transports food made in the leaves to all parts of the plant.
Perennials
plants that last for more than one growing season
Self pollination
within the same flower
Fruit and seed development
A Seed consists of three parts
Vascular Cambium
the growth tissue that produces new xylem and phloem cells in the stems of woody plants
Gymnosperms
-Lack a protective covering around their seeds, and they do not produce flowers
Cross pollination
from one flower to another flower
three parts of a seed
The embryo
The stored food
The seed coat
Herbaceous Stem
green and flexible-grow, mature, reproduce and die in one season “annuals”
Angiosperms
Have a protective covering around their seeds and they do produce flowers and all produce some kind of fruit
Evergreens
conifers or cone bearing plants
Simple
A simple fruit is formed from a single ovary
Woody stem
are harder and stiffer than herbaceous stems and contain wood cells that give them support
Photosynthesis
Plants absorb sunlight
Conifers
mean cone bearing-pines, spruces and firs
Aggregate
form from several ovaries
