reproduction until in a living
cell(host).
Obtaining Food= they are
parasites.
Reproduction= Asexual
reproduction through
Replication.
Not made of a cell or cells.

Kingdom: Protista
Eyespot: used to detect
light.
When light is present, it acts
as an autotroph (carries out
photosynthesis); when light
is not present, it acts as a
heterotroph.
Gas Exchange: Diffusion
through the plasma
membrane.
Has Mitochondria: synthesis
its own ATP by respiration.
Unicellular: Eukaryotic cell
(has nucleus)
Algae- Volvox
algae
Volvox
1. Kingdom- Protista
2. Autotroph: carries out
photosynthesis.
3. Reproduction- Fragmentationasexual; produces clones;
eachalgae
little piece becomes a
new organism.
4. Gas Exchange: CO2 in and O2
out
5. All algae is protist made of
eukaryotic cells; some
unicellular and some
multicellular.
Fungus-like Protists
(Slime molds and Water Molds)
1.Heterotrophs-
saprophytes
2.Multicellular- no chitin in cell wall.
3.True fungi have chitin in cell wall.
4.Reproduction- Asexual called
sporulation.
Concept Map on Protists
1.Animal-like Protists are called protozoans.
2.Zooflagellates swim with a flagellum.
2.Sarcodines use pseodopods (false feet).
3.Ciliates use cilia (hair-like projections).
4.Sporozoans
live in a host… fish, birds humans etc.
They reproduce by spores.
5.Plant-like Protists are called Algae.
6.They exist in a wide variety of sizes and colors.
7.Contain chlorophyll; can conduct photosynthesis.
8.Six groups of algae: Diatoms, Dinoflagellates,
Euglenoids, Red Algae, Brown Algae, Green Algae.
Mushrooms- Fungi Kingdom
1.A
mushroom carries out asexual
reproduction called sporulation- each spore
is a clone of the parent.
2.Mushrooms are heterotrophs- release
enzymes over dead plant material- food is
liquified and absorbed into mushroom’s
body.
3.Mushrooms are saprophytes- food source is
dead or dying plant material.
Yeast- Fungi Kingdom
1.Asexual
reproduction: called budding.
2.Important in alcohol fermentation. (produces
two ATP and CO2)
3.Used in baking bread; release CO2 which
causes bread to rise.
Draw Yeast
Lichens= Fungi Kingdom
1.Lichens
are a symbiotic relationship
between algae and fungus.
a. Fungus provides protection, water and
minerals.
b. Algae carries out photosynthesis to
provide food for both.
2.Lichens are major producers in the Tundra
Biome.
3.Lichens grow on rocks and break them
apart to provide fertile soil.
4.They are good indicators of air pollution.
Leaf
1.Xylem
transport H2O to all cells.
2.Phloem transports sugar (glucose) to all cells.
3.Guard Cells opens and closes stomata.
4.Palisade Mesophyll= where the majority of
photosynthesis happens.
5.Transpiration (H2O moves out) happens at
stomata.
6.Vascular Bundle= contains Xylem and Phloem.
Seed
1.A
seed carries the embryo; embryo formed
by sexual reproduction known as pollination
which occurs in flowering plants called
angiosperms.
2.Seed is compared to the uterus of a female
because both carry the embryo.
3.For a seed to germinate when placed in the
soil, conditions must be favorable; H2O; O2;
temperature (warm); Earthworms help
increase O2 in the soil by turning it over as
they crawl
The Flower
1.Male reproductive parts are: .amen, anther
and filament, the anther produces pollen and
pollen carries the sperm cell.
2.Female reproductive parts are: pistil, stigma,
style and the ovary. Pollen lands on the stigma
and sperm cells are carried to the ovary by the
pollen tube. When the ovary is fertilized you get
a fruit in the end. No flower – no fruit.
Fertilization
1.Part
of the male gametophyte grow
through the pistil to reach the female
gametophyte in flowering plants.
2.Double fertilization involves two sperm
nuclei.
3.A zygote (2n) and endosperm (3n) are
formed.
Do book drawing and write
information in picture.

Process of Fruit Formation
All vegetables are fruit to a scientist because
they are formed from a flower.
2.When the eggs in the ovules of a blueberry
flower have been fertilized, the petals, stamen
and stigma wither and fall away.
3.The wall of the blueberry flower’s ovary
becomes fleshy as the seeds develop.
4.The remains of the sepals and some dried
stamens usually can be seen at the top of a
blueberry fruit.

Understanding Roots
1. Apical
Meristem= high rate of mitosis
(new body cells)
2. Xylem= transport H2O and minerals.
3. Phloem= transports sugar (glucose)
4. Xylem and Phloem in plants compare
to arteries and veins in animal
transport.
Plant Responses
*** Plant Responses are controlled by
Hormones called Auxins.***
1. Thigmotropism= plants touch object and
vines wrap around object.
2. Phototropism= plants bend toward light or
sunlight.
3. Geotropism or Gravitropism= roots grow
down and stems grow up.
a.
Positive Geotropism= roots always grow
down.
b.
Negative Geotropism= stems grow
4. Nastic
Movement= venus flytrap leaves fold
around insect that lands on it; traps the
insect and it dies- juices of dead insect used
by plant.
(Pictures to be drawn for each)
Plant Responses of Flowering Plants=
Photoperiodism
1. Many
plants are day-neutral. Flowering in
cucumbers, tomatoes, and corn is not
influenced by a dark period.
2. Spinach and lettuce are long-day plants that
flower in midsummer.
3. Short-day plants include pansies and
goldenrod.
(Pictures to be drawn for each)
