what is the importance of photosynthesis?
It provides food for plants and exchanges carbon-dioxide for oxygen
What is the equation for photosynthesis
CO2 + H2O ------->C6H12O6+O2
Carbon Dioxide + Water----------------->Sugar+ Oxygen
Helps support the tree, older xylem near the center of a woody stem that no longer conducts water
inner bands of light wood and outer rings of dark wood on a tree; tell the age of trees and how much water it has received
brightly colored structure just inside the sepals; attracts insects and other pollinators to a flower
The pollen-producing male reproductive organ of a flower, consisting of an anther and filament.
life cycle of angiosperm
First, tree produces flowers; Second, cells in anther produce pollen grains and inside ovary an egg cell is produced in each ovule; Third, pollen grains are trapped on stigma; Fourth, pollen grain produces a pollen tube that grows into ovule and a sperm cell moved through pollen tube and fertilizes egg cell; Fifth, ovule develops into a seed and fertilized egg becomes the seed's embryo and other parts of ovule develop into seed coat and the seed's stored food; Sixth, ovary and other structures develop into a fruit that encloses the seeds and fruit helps in seed dispersal; Seventh, a seed grows into a new plant
A flowering plant that has a life cycle lasting only a single year or growing season followed by death.
what does Bernoulli's principal state
Bernoulli's Principle says that increased air velocity produces decreased pressure.
how does Bernoulli's principal relate to birds flight
the curve shape on the top of a wing makes for higher velocity which creates low pressure (see Bernoulli's Principal)
