In which direction does passive transport (no energy required) move materials across the membrane?
high to low, with the natural flow or gradient
Inside this important organelle, DNA (genetic material) is stored. What organelle is the control center?
nucleus
Chemical energy- product of cellular respiration
ATP
This organelle provides support and protection to plants, so much so that animal cells do not have them. What organelle and why don't animals have them?
cell wall; they would restrict movement
According to the cell theory, all living things are ....
made up of one or more cells
Name the two example/forms of passive transport.
diffusion and osmosis
Prokaryotic cells have ___________ ___________________, are small and simple and lack membrane bound __________________________.
no nucleus, organelles
This substance, pigment is green in color and found inside an organelle in plant cells. This pigment allows absorption of sunlight energy from the sun.
chlorophyll
This organelle is like a storage container for water and minerals inside the cell. Plants have 1 large one. Animals have several smaller ones.
vacuole
This TYPE of cell is small, no nucleus and uses flagella (tail like thing) for movement.
prokaryote
What TYPE of cell is shown here?
eukaryotic (animal)
Where do all cells come from?
pre-existing cells
What is required for cellular respiration to occur?
glucose and oxygen
In ____________________ transport, materials are moved from low to high concentration.
active
The largest organelle inside a plant cell hold water and other waste. It can be compared to a storage container. What organelle is this?
vacuole
What are the products of photosynthesis?
O2 (oxygen) and glucose (sugar- plant food)
This eukaryotic cell has lysosomes.
animal cell
In which organelle does cellular respiration take place?
mitochondria
Why is photosynthesis just as important to animals as it is plants?
Animals use glucose and oxygen from plants to make ATP; we eat vegetables (plants) for food & so do other animals (meat) we eat
What process is taking place?
diffusion
Which form of cellular transport requires energy to move large particle into the cell from the outside?
endocytosis
Which eukaryotic cell is more square in shape, has 1 vacuole and chloroplasts?
plant cell
This organelle is responsible for regulating the passing of nutrients into the cell and getting rid of waste out of the cell.
cell membrane
What gas do plants take in from the air around them as a reactant for photosynthesis?
CO2, carbon dioxide
Plants and animals use which cellular energy process to get the energy required for daily functions?
cellular respiration
What is the purpose/function of lysosomes only found in animal cells?
get rid of waste; digest waste and foreign matter
These green organelles are found inside plants and are the site of which cellular energy process?
chloroplast; photosynthesis
What are the products of cellular respiration?
ATP, water, CO2
By looking at a slice of a cork tree under a microscope, _____________ ______________ discovered cells stating that they looked like little empty rooms.
Robert Hooke
What process is taking place?
exocytosis
In a school setting, the nucleus compares to what?
the principal
What is the purpose of a decomposer and why would you NOT find chloroplast in one of them?
To break down the remains of dead organisms so that the Earth is not covered in waste; decomposers are heterotrophs, not autotrophs & do not need chloroplast
What are the 3 reactants for photosynthesis?
sunlight, water, carbon dioxide
Plants are not active and require less energy to function. Animal are very active. Therefore you would expect to find more of what organelle inside animals vs plants?
mitochondria
When an item is placed in water overnight and swells, which cellular transport process is taking place?
osmosis
