what is the importance of photosynthesis?
It provides food for plants and exchanges carbon-dioxide for oxygen
where does photosynthesis take place in a plant?
What is the equation for photosynthesis
CO2 + H2O ------->C6H12O6+O2
Carbon Dioxide + Water----------------->Sugar+ Oxygen
sac-like structure that stores water, waste and food
strong layer around the cell membrane in plants, algae, and some bacteria
green jelly bean structures in which photosynthesis occurs
a green pigment found in chloroplasts which is located in the leaves of plants.
chemical instructions that direct the cells activities
stores, a seed leaf that stores food
An organism in the earliest stage of development from a zygote
protective outer layer of seeds of flowering plants
the vascular tissue through which food moves in some plants
the vascular tissue through which water and nutrients move in some plants
tiny structures that contain the cells that will later become sperm cells
the plant structure that contains a young plant inside a protective covering
occurs when the embryo begins to grow again and pushes out of the seed
protects the root from injury from rocks as the root grows through the soil
vascular tissue that produces xylem and phloem cells as a plant grows
a structure that holds a plant up and supports its leaves
Small openings on a leaf through which oxygen and carbon dioxide can move.
the waxy, waterproof layer that covers the leaves and stems of most plants
group of similar cells that perform a particular function
plant that has tubes and transports material
containing no plant tissue through which water and food move
evaporation of water from a plant's leaves
animals, water and wind
takes in air and light - makes food for plant
Absorbs water and minerals from the ground. Anchors plant in ground.
old phloem that protects the tree
active phloem that moves food around tree
area in plants that surrounds heartwood and is active in fluid transport
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
function of stomata
Exchange gases (absorb co2, release 02) and lose water through transpiration
characteristics of angiosperms
Produce flowers, and produce seeds that are enclosed by a fruit
examples of angiosperms
Oak, Maple, Grass, Daisey, Apple
the female ovule-bearing part of a flower composed of ovary and style and stigma
Leaflike parts that cover and protect the flower bud
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
benefits of mulch
(see page in binder)
A flowering plant that has a life cycle lasting only a single year or growing season followed by death.
Flowering plant that lives for more than 2 years
pigment - gives plants a green color
red panda scientific name
Tennessee state tree scientific name
(Tulip Tree) Liriodendron tulipifera
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)
characteristics of teeth of mammals
incisors-cutting(vegetables), Canines-Stabbing(meats), Molars- Grinding (hard foods)
