SCIENCE #2 Flashcards
(25 cards)
name the 3 parts of a seed
seed - coat , embryo, endosperm
what does a root do?
it keeps the plant in the ground and absorbs the nutrients and water
how does a stem work?
it supports leaves and reproductive system , it provides a healthy pathway for the movements of water and nutrients
what does the fruit do ?
it proctects the developing seeds
what does the leaf do?
it performs photosynthesis and gas exchange
what does the flower/ cone do?
it attracts pollinators and contains the male and female reproductive system
what is a seed coat
its the tough outer layer that protects the embryo
what is an endosperm
its stored food for the baby plant
what is an embryo
its the baby plant
transports water and dissolved minerals one way from the roots up to the leaves
xylem
transports food ( SUGAR) up or down the plant to where its needed ( TWO WAY MOVEMENT)
pholem
happens at the leaves of a plant through stomta
gas exchange
carbon dioxide + water+ light/ chlorphyll + glucose+ oxygen
photosynthesis equation
glucose+ oxygen + energy released + carbon dioxide + water
cellular respiration equation
what are the male parts of the flower and how does it work
anther: produces pollen
filament: supports anther
what are the female parts of a flower
stgima, syle ,ovule,ovary
what are the asexual parts of a flower
sepal,petal,stem,pediciel
movement of gases and water from a high consentration to a low consentration
diffusion
water moves from a high consentration to a low consetration
osmosis
allows plants to absorb mineral ions
active transport
a stem that grows above or just below the ground
runners
stems that grow horizontally underground
rhizomes
roots growing between the surface or soil
suckers
2 or more plants that grow together
grafting
