WorksheetsCell Transport and Energy
Total questions: 22
Worksheet time: 42mins
Substances enter and leave the cell through openings in the
cell membrane
organelles
cell wall
nucleus
What is the difference between active and passive transport?
Passive transport does not use the cell's energy, Active uses the cells energy.
Passive transport involves water. Active transport involves proteins.
Passive transport is for large substances. Active transport is for small substances.
Active transport moves things from high to low concentration. Passive moves things from low to high concentration.
Substances too large to pass through the cell membrane enter the cell in a process called
endocytosis
exocytosis
passive transport
active transport
The passive transport of water through a membrane is
osmosis
equilibrium
fermentation
active transport
What do mitochondria do?
produce proteins
contain chlorophyll
release energy from broken down food molecules
store food, water and waste materials
How are osmosis and diffusion related?
osmosis is the active transport of water
osmosis is the passive transport of water through a membrane by diffusion
osmosis is the movement of water from low concentration to high concentration
osmosis is the movement of water without a membrane
Why is water necessary for life?
Water makes up approximately 75% of a cell's volume
Water dissolves many substances and carries them across the cell membrane
Water play an important role in many chemical reactions
All of these
Animals use chlorophyll to produce glucose
true
false
During glycolysis and fermentation, glucose is broken down.
true
false
Energy is released during photosynthesis
true
false
Sunlight, water and carbon dioxide are needed to begin fermentation.
True
False
Respiration takes place in the cytoplasm and mitochondria of most cells.
True
False
Photosynthesis takes place in cells with chloroplasts.
True
False
Which form of energy is necessary in photosynthesis?
ATP
glycolysis
lactic acid
sunlight
During periods of vigorous activity, muscle cells run low on
oxygen
carbon dioxide
ATP
lactic acid
The process that releases energy without using oxygen is
photosynthesis
osmosis
respiration
fermentation
Photosynthesis is the process in which plants use energy from light to produce
new cells
glucose
organelles
Which of the following is NOT involved in photosynthesis or respiration?
water
carbon dioxide
chlorophyll
lipids
Respiration is the process in which organisms break down food to release
energy
sugar
nutrients
oxygen
Where in the cell, does glycolysis take place?
cytoplasm
nucleus
mitochondria
chloroplast
Photosynthesis slows down in the fall because
There is less light available
Leaves fall off the the trees
chlorophyll starts to decay
all of these
What are some reasons animals rely on photosynthesis
they get food and oxygen from it
they get water and carbon dioxide from it
they get to absorb sunlight
they get to enjoy the pretty flowers
