Cellular Respiration and Photosynthesis Quiz
what are the starting products of photosynthesis?
carbon dioxide, water
cells use oxygen to release energy during _________
cellular respiration
light energy is captured by the green pigment ________
chlorophyll
where does cellular respiration take place?
cytoplasm and cell membranes of prokaryotic cells; mitochondria of eukaryotic cells
what do plants gain from sunlight?
energy
which cells in your body undergo cellular respiration?
every cell in your body
ATP is to your cells as ________ is to a car
gasoline
how do plants store chemical energy?
glucose (a sugar) stores the energy
what are the starting products of cellular respiration?
glucose, oxygen, ATP (chemical energy)
chlorophyll
green pigment found in the chloroplasts of plants, algae, and some bacteria
in photosynthesis, water molecules are split into ______ and ________ atoms.
hydrogen and oxygen
if you were looking for a plant's chloroplasts, where would you find them?
in the leaves or any place green
what does chlorophyll do?
it captures energy from sunlight and uses it to combine carbon dioxide and water, which forms a sugar called glucose and oxygen gas
Could cellular respiration happen without photosynthesis? Explain your reasoning.
No, they both need each other to work. Photosythesis produces the oxygen and sugar needed for cellular respiration. Cellular respiration produces the carbon dioxide and water needed for photosynthesis.
what are the connections between photosynthesis and cellular respiration?
Photosynthesis is the end product of cellular respiration, and cellular respiration is the beginning products of photosythesis.
how do plants and animals get their energy in different ways?
Plants create and get their energy from the sun and photosythesis. Animals have to eat other organisms to get energy.
Plants don't move around, so why do they need energy?
They need energy because without it they couldn't photosynthesize, and if they couldn't photosynthesize they wouldn't be able to make their own food. Without food they wouldn't have energy, which would cause them to die.
Does your body get all its energy from the sun? Explain.
Yes, because plants make their own food that we eat. Also san animal could eat a plant and we could eat that animal.
what is ATP and what does it do?
a molecule that stores and releases energy; it powers many of the chemical reactions needed for cells to survive
photosynthesis
a process in which plants use energy from sunlight, carbon dioxide, and water to make sugars
what is photosynthesis?
a series of chemical reactions that convert light energy, water, and carbon dioxide into the food-energy molecule glucose and give off oxygen
chlorophyll is a type of pigment, and is the melanin in your skin. what is pigment?
a substance that contains color
how do we get the glucose we need to power our cells?
by eating
what do the respiratory system and cellular respiration have in common?
oxygen plays a key role in both
_______ takes place in organelles called chloroplasts
photosynthesis
in what way does plant nutrition differ from human nutrition?
plants make their own nutrients; humans must consume theirs
cellular respiration
the process of breaking down food to produce ATP
chloroplast
these organelles are found oly in the cells of plants and other organisms that undergo photosynthesis
what do plant cells do to glucose?
they break it down for energy, the excess sugars are stored in teh body of the plant, they are usually stored as starch (in the roots or body of the plant)
what might happen if plants could not produce glucose?
they could not grow and function
how does your body get rid of the carbon dioxide produced by cellular respiration?
through your lungs
