Parts of a flowering plant
Stigma
Style
Anther
Carpel
Ovary
Stamen
Filament
Receptacle
Sepal
Stomates
It’s prime function is to exchange gases by closing and opening pored in leaves,it assist in monitoring the movement of water via transpiration
The primary function of
stomates
is to exchange
gases
Chlorophyll
Absorbs
light energy
which is transferred to
energy storing molecules
Photosynthesis
Carbon dioxide
+ Water ->
Sunlight glucose
+ oxygen
Photosynthesis reactants
Sunlight
Carbon dioxide
Water
Photosynthesis products
Glucose
Oxygen
Pistil
The female
reproductive
part of a flower, The carpel holds a sac-like structure in the middle that’s known as the ovary
Ovary
The part of the carpel that contains the
ovules
Petal
Highly pigmented and scented to attract
pollinators
and protect
reproductive organs
Sepal
Green leaf-like structure that
protects
the flower bud
Stamen
The male
reproductive
part of a flower, containing the filament and
anther
Filament
Part of the
stamen
that supports the
anther
Seed coat
Protective
outer layer that protects the seed from
damage
Epicotyl
The shoot of the embryo, which develops into the entire shoot system
Hypocotyl
The transition between the
growing
shoot and
root
of the embryo
Radicle
The tiny
root
of the embryo
Cotyledons
The
leaves
of the embryo that provide
nourishment
to the developing plant
Seed germination
1. Seed takes in
water
2. Seed
coat
splits
3. Embryo uses
oxygen
to grow further
4. Stem grows
upwards
, root grows
downwards
5. Seed coat
falls
off, revealing
cotyledons
6.
Root
system develops
Chloroplasts
Plant cell organelles that convert light energy into relatively stable chemical energy via the photosynthesis process
Chloroplasts
convert light energy into chemical energy via
photosynthesis
Xylem
Transports
water
and
minerals
from roots to leaves
Phloem
Transports food (
glucose
) from
leaves
to other parts of the plant
Types of plant roots
Fibrous
Tap
Mater
Anything that takes up space and can be weighed
Evidence for
kinetic
theory of matter: ice (solid water) melts and changes phases into liquid water
3 State of Matter
Solid
Liquid
Gas
Solids
Hard
Have definite shape,
volume
(
fixed
)
Particles are
packed
tightly together in a
fixed
arrangement
Liquids
Flow and take shape of their container
Particles can be
compressed
Particles can
vibrate
and
slide
around each other
Gases
Can
flow
and completely
fill
their container
Particles are free
floating
with no arrangement
Particles can
move
around quickly in all directions and
collide
with each other
Physical Changes
1.
Melting
2.
Vaporisation
3.
Condensation
4.
Sublimation
5.
Deposition
Freezing
Change of state from
liquid
to
solid
Evaporation
Type of
vaporisation
, that happens when a liquid turns into a
gas
Condensation
Change of state from
gas
phase into
liquid
phase
Sublimation
Solid
to
gas
transition, without passing through liquid state
Deposition
Gas
to
solid
transition
Condensation
Gas
to
liquid
phase change
Evaporation
Liquid
to
gas
transition
Heat added to Ice
1. Water can exist as a solid (
ice
)
2. Water can exist as a liquid (
water
)
3. Water can exist as a gas (
vapour
or
gas
)
4. Adding heat can cause ice (solid) to
melt
to form
water
When
water
changes to a solid or a
gas
, the matter stays the same even though the physical form changes
