Beechdrops epifagus virginiana are leafless plants that lack chlorophyll beechdrops get

Beechdrops (Epifagus virginiana) are leafless

plants that lack chlorophyll. Beechdrops get

their nourishment from the roots of beech trees, which reduces the amount of nutrients available to the trees themselves. This interaction is best described as —

A. predatory

B. parasitic

C. commensalistic

D. mutualistic


Beechdrops epifagus virginiana are leafless plants that lack chlorophyll beechdrops get

According to this food web, which of these is an omnivore?

A. Caterpillar

B. Mouse

C. Ant

D. Fly larva


Which molecule provides most of the energy used to drive chemical reactions in cells

Which molecule provides most of the energy used to drive chemical reactions in cells?

A. DNA

B. RNA

C. ATP

D.ADP


Photosynthesis

PHOTOSYNTHESIS

To create

Light

Purpose: Plants use light to create sugars (glucose-C6H12O6)


What is photosynthesis

What is photosynthesis?

  • The process in which plants convert light energy into chemical energy (food glucose).

  • Happens in the chloroplast


Photosynthesis equation

Photosynthesis Equation

  • PHOTOSYNTHESIS EQUATION:

    It will be on every quiz and your unit test!

    Carbon dioxide + water + E → glucose + oxygen

    6CO2 + 6H2O + E → C6H12O6 + 6O2

Within the chloroplast pictured above are disc like structures arranged in stacks called grana. The stack like membranes contains pigments that absorb light energy. The individual disc-like shaped structures labeled A are called ____.

A. chlorophyll

B. thylakoids

C. stroma

D. Golgi apparatus

Which word summary word equation best describes a process that directly requires light energy

Which word summary word equation best describes a process that directly requires light energy?

A. water + carbon dioxide  glucose + oxygen

B. glucose + glucose  maltose + water

C. glucose  alcohol + carbon dioxide + ATP

D. water + glucose  oxygen + carbon dioxide  ATP

Vein


Beechdrops epifagus virginiana are leafless plants that lack chlorophyll beechdrops get

Water enters the plant through the roots and travels up to the leaf through the veins.

Water then travels to each cell through a process known as OSMOSIS.

Stomata

Stomata are the little “holes” on a plant leaf that regulates the gas exchange in plants.


Beechdrops epifagus virginiana are leafless plants that lack chlorophyll beechdrops get

Carbon dioxide enters the leaf through the stomata.

Carbon dioxide then travels to each cell through a process known as Diffusion.


Which structure regulates gas exchange during the processes of photosynthesis and respiration

Which structure regulates gas exchange during the processes of photosynthesis and respiration?

A. Q

B. R

C. S

D. T


Products and reactants in photosynthesis

Products and Reactants in Photosynthesis

  • Reactants- Carbon Dioxide and Water

  • Products- Glucose and Oxygen

  • There is NO ATP gain during photosynthesis!

    • *****Remember the ATP Cycle*****


Light and pigments

Light and Pigments

  • Photosynthesis depends onpigments -proteins that absorb some light and reflect others.

    • Examples: chlorophyll and carotene


Light and pigments1

Light and Pigments

  • Chlorophyll absorbs blue, violet, and red light, but reflects green light.

    • This is why plants are green.

  • Carotene reflects orange light.


Which compound is a product of photosynthesis and a reactant for cellular respiration

Which compound is a product of photosynthesis and a reactant for cellular respiration?

A.carbon dioxide

B.water

C.glucose

D.energy


Why are photosynthesis and cellular respiration often considered opposites

Why are photosynthesis and cellular respiration often considered opposites?

A. Photosynthesis produces twice as many ATP molecules as cellular respiration does.

B. Water is released during photosynthesis and consumed during cellular respiration.

C. Photosynthesis occurs during the day, and cellular respiration occurs at night.

D. Oxygen is produced during photosynthesis and used during cellular respiration
