Chapter 2 How Cells Function
cellular respiration
Both a whale and a seaweed use which of the following to change glucose into energy?
oxygen
Both plants and animals obtain energy from food by the process of cellular respiration. What substance do plants produce during photosynthesis that is necessary for cellular respiration to take place?
oxidizing agent, oxidizing organic compounds
During cellular respiration, oxygen serves as a(n)
only used in the light-independent reaction
During photosynthesis, carbon dioxide is
the sun
During photosynthesis, plants produce "food" for themselves. When animals eat plants, they take in energy that originally came from:
carbohydrate
During photosynthesis, plants produce glucose, which is a
chemical energy
During photosynthesis, producers convert energy from the sun into
energy
Grass produces glucose during photosynthesis. A cow eats grass. When the cow breaks down the glucose, what is being supplied to the cow from the grass?
chloroplast
In a plant cell, which organelle is the site of photosynthesis?
oxygen
In fermentation, cells release energy without
light energy
Leaf cells use chlorophyll to absorb
mitochondria
Which organelle is the site of cellular respiration?
chlorophyll
Which plant pigment traps most of the light energy used in photosynthesis?
photosynthesis
Which process occurs in chloroplasts?
osmosis
Which word means" diffusion of water across cell membranes?
lipid
are found in the fats, oils and waxes used for structure and to store energy
nucleic acid
A type of molecule, made up of subunits of nucleotide, that is part of the genetic material of a cell and is needed to make proteins
chloroplasts
Animal cells cannot carry out photosynthesis because they lack
water
Osmosis is the diffusion of ______ into or out of the cell through the cell membrane
Photosynthesis produces oxygen while respiration produces carbon dioxide.
Photosynthesis and respiration both occur in plant cells as two important chemical processes. What are the differences in the processes?
cellular respiration
The cells of a redwood tree require oxygen for the process of
lipids
The fats, oils and waxes found in living things are known as
active transport
The movement of materials across a cell membrane, requiring energy, is called
chemical reaction
The process by which chemical changes occur
leaf
Where on a plant does photosynthesis take place?
organic carbon
Which of the following is a product of photosynthesis
CO2 (carbon dioxide) and H2O (water)
What are C6H12O6 (glucose) and O2 (oxygen) converted into in cellular respiration
O2 (oxygen) and C6H12O6 (glucose)
What are carbon dioxide (CO2) and water (H2O) converted into as a result of photosynthesis
proteins
What do cells use as a source of energy and for energy storage?
protein
control the chemical activity of a cell and support growth and repair.
