plants for food and fibre
seed plants
plants that make seeds
stems
provide pathway for movement of food and water
seeds
contain an embryo that will form a new plant
leaves
produce food for the plant
cones
There are separate
male and female cones
for reproduction
roots
Absorb water and dissolved nutrients.
• Anchor the plant in the soil.
tanspiration
the evaporation of water from the surface of plant
(mainly the leaves)
capillary action
Water travels from the roots to the leaves through
tiny tubes in the roots and stems
The water particles are attracted to the walls of the
tubes
photosynthesis
The process in which plants make food
Photosynthesis takes place in chloroplasts which are
green structures in leaves
cellur respiration
The process to use food (made by the plant) “Producer”
Plants use the sugar created during photosynthesis for
food and their own energy.
Carbon dioxide and water is given off as waste.
diffusion
The movement of particles from an area of high concentration to an area
of low concentration, until there is an equal amount of particles everywhere
osmosis
the movement of water across the cell membrane in the roots.
Water moves from high concentration, through the membrane to an area
of low concentration
This is how water moves from the soil into the roots
active transport
Another method used to move substances in and out of a plant cell.
Use energy to move substances in and out of plant cells.
3 stages of a seed plant
1.seed stage
2.seedling stage
3.adult stage
pistal
femal reproductive organ
stigma
The sticky top of the pistil that captures the pollen
grains.
style
stalk that supports the stigma
ovary
swollen
base of the pistil
containing ovules.
stamen
male reproductive organ
anther
where pollen is poduced and stored
filament
stalk that supports that anther
petal
brightly
coloured to attract
birds and insects.
ovules
sacks
containing female
reproductive cells.
sepal
green,
protects the flower
before it opens.
(underneath after it
opens)
pollinators
Organisms that carry pollen (male cells) from
one flower to another.
vegatative reproduction
Reproduction of plants that doesn’t involve seeds
runners
long along stems that grow “run along” the surface of the soil.
rhizomes
stems that run underground
bulbs, tubers, and corms
underground stems close to the plant
grafting
attaching a part of one plant onto another plant.
optimal growth
Knowing exactly what the plant needs and the
conditions required for different stages of its
life can increase the growth of a plant.
organic particles
particles in the soil that come from plants and animals that have died
