Photosynthesis &
Respiration Review

Quiz Review

Multiple Choice

What does a plant get out of photosynthesis (what are the products)?

• Water and Carbon Dioxide

• Carbon Dioxide and Sugar

• Sugar and Oxygen

• Sugar and Water

Photosynthesis Equation

Light can also be included on the left as a reactant

Multiple Choice

Where does photosynthesis happen?

• Chloroplasts

• Stomata

• Chlorophyll

• Mitochondria

Photosynthesis

Requires Light

Happens in the
chloroplasts

Is done by autotrophs with
chlorophyll (plants, some
algaes & some bacterias

Multiple Choice

Where does carbon dioxide enter a plant?

• the roots

• the stomata

• the chloroplast

• the cell wall

Stomata are small
openings (usually) in
the bottom of a leaf.

Where gasses are
exchanged.

Multiple Choice

What are the products of cellular respiration?

• water and sugar

• water, sugar, and carbon dioxide

• carbon dioxide, water, and energy

• oxygen, sugar, and energy

Cellular Respiration Equation

Multiple Choice

When does cellular respiration happen?

• only in the light

• only in the dark

• all of the time

Respiration does
not require light.

Must happen all
of the time for
the organism to
survive.

Multiple Choice

What does respiration?

• plants, animals, bacteria, and algae

• plants, some bacteria, some algae

• animals, bacteria, and algae

• plants and animals

Respiration
happens in the
mitochondria

Plants, animals,
bacteria, and
algae all do
respiration.

Multiple Choice

Photosynthesis and respiration are a cycle. What one gives off, the other needs.

• True

• False

What one gives off, the other requires.

Reflection & Refraction Review

Quiz Review

Multiple Choice

The bouncing of light is...

• reflection

• refraction

Reflection

Bouncing of Light

Light bounces offa smooth surface better than a rough
surface

Multiple Choice

What kind of mirror is this?

• Convex

• Concave

• Plane

Types of Mirrors

Plane = Flat

Concave = “caves in”
*Think the inside of a bowl or
spoon.

Convex = bows out
*Think the outside/bottom of a
bowl or spoon.

Multiple Choice

On a flat (plane) mirror, the light coming out matches the angle of the light going in.

• True

• False

Angle of light in = Angle of light out

Multiple Choice

The bending of light is...

• refraction

• reflection

Refraction

Bending of light

Change in medium changes angle of light.

Multiple Choice

What type of lens is this?

• Concave

• Convex

Types of Lenses

“Caves in”

Separates
light rays

Bows out

Brings light
rays together
into focal
point

Multiple Choice

What kind of light can we see?

• Ultraviolet

• Infrared

• Visible

We see VISIBLE light

Multiple Choice

A lemon looks yellow because yellow light is reflected off of it and all other colors are absorbed.

• True

• False

Colors

The color of white light that is reflected is
the color we see.

White light can
be broken into
the colors of the
Rainbow using a
lens/prism.

White = all colors reflected
Black = all colors absorbed.

Multiple Choice

If there is any light at all, we can see something.

• True

• False

If there is light, we
can see things.

Only when there is
NO LIGHT can we
see nothing.
