When mold begins growing on an object,
describe what is happening.
– The fungus releases strong juices (enzymes) that
break down the plant and animal matter. A typical
fungus is made up of tiny tubes called “hyphae”
which help the fungus absorb and digest its food.
Plants Review - #2
When a plant begins the process of germination,
describe what it is doing.
– The germinating plant is starting to sprout and
grow. In both monocots and dicots, this process
starts with the root extending from the seed.

You notice that the large leafed plant in your house
needs to be watered much more often than the
small leafed plant. Both plants are the same height
and width. Which of the following processes
explains this scenario? Use claim, evidence and
reasoning to explain your choice.

You notice that the large leafed plant in your house
needs to be watered much more often than the
small leafed plant. Both plants are the same height
and width. Which of the following processes
explains this scenario? Use claim, evidence and
reasoning to explain your choice.
⁻ Transpiration is the process of plants releasing
excess water through the stomata in their leaves.
⁻ The plant with more leaf surface area has more
stomata and will release more water, so it needs
to be watered more often.
⁻ Stomata also let in the carbon dioxide needed for
photosynthesis and let out the oxygen.
⁻ We needed to water our bean and corn plants
more often after they grew leaves.

All species of organisms that reproduce sexually,
undergo a process called fertilization. What is it
and how does it work in plants?
– Fertilization occurs with the nucleus of a sperm cell
(male) joins with the nucleus of an egg cell (female).
– In plants this happens when pollen (sperm) enters the
stigma and joins with one of the many ovules (eggs)
inside of the ovary.

Humans consume and digest food to gain the energy
needed to perform life processes. Name and explain
the process that plants use to gain energy.
– Photosynthesis is the process that plants use to transform
light energy from the sun into chemical energy they can use.
– This is done by combining carbon dioxide, water and sunlight.
– The products (outcome) of photosynthesis are
oxygen, water vapor and glucose (sugar).
– Chloroplasts are the organelles
that perform this process.
Plants Review - #6
Define pollination and explain the different types
in detail.
⁻ Pollination is the process of pollen being transferred
from the male part of a plant (stamen) to the female
part (pistil).
⁻ There are two types of pollination.
⁻ Cross-pollination happens when the pollen from one
plant is transferred to the
pistil of another, usually by
an animal or wind.
⁻ Self-pollination happens
when pollen from a flower
enters its own pistil.

In a plant’s life cycle it will undergo 5 major
processes. Imagine that it is starting as a
dormant seed. Put these processes in order of
occurrence and be ready to defend/explain
your decisions. Fertilization, Photosynthesis,
Germination, Pollination, Transpiration
– Germination  Photosynthesis/Transpiration
 Pollination  Fertilization
– Germination comes first because the plant
must grow before it can perform any of the
other processes.
– Photosynthesis and Transpiration begin as
soon as the plant has leaves and continue
throughout the plant’s life cycle.
– Pollination happens when the plant has
matured enough to reproduce.
– The process of transferring pollen leads to
fertilization, or the egg and sperm uniting.

Describe some parts of a
flowering plant.
– Pistil & Stamen
– Pistil holds the female
portion of flower – style,
stigma, ovary, ovule
– Stamen holds the male
portion of flower –
filament, anther (pollen)
– Examples are Wisconsin

Describe some parts of a
flowering plant.
– Perfect Flowers have
both the male and
female reproductive
parts.
– Imperfect Flowers have
male OR female
reproductive parts.

Macroscopic Review - #9
When asked to identify a member of the Animal
Kingdom, what do you notice that makes an
animal different from plant or fungi?
Plants are different from
animals since they make
their own food (called
producers).
Plants are similar to
animals in that they are
multi-cellular organisms.

When asked to identify a member of the Animal
Kingdom, what do you notice that makes an
animal different from plant or fungi?
Fungi are different from
animals since they live on
their food breaking it down
(often called decomposers).
Fungi are similar to animals in
that they are multi-cellular
organisms. Also, fungi are
consumers

You notice that the life cycle of a Cabbage White
Butterfly has several distinct stages. What are
the stages and how many are there?
⁻ Butterflies are an insect who go
through the process of
“metamorphosis” (the process of
transformation from an immature
form to an adult form in two or
more distinct stages – “change
shape”)
⁻ Many insects have four distinct
phases of metamorphosis – egg,
larva, pupae and adult

You notice that the life cycle of a Cabbage White
Butterfly has several distinct stages. What are
the stages and how many are there?
⁻ Eggs are laid on
the underside
of a leaf
⁻ Larva (caterpillar) eats
leaves – 5 stages
