Flashcards in Cells And Microsocpy Deck (25):
Name the sub cellular structures of both plants and animals
What are the three things plant cells have and animal cells do not?
Where is the genetic material found in in an animal cell?
Where is the genetic material found in a bacteria cell?
Single circular strand of DNA
What type of organism are bacteria ?
What gives a higher resolution a light or electron microscope?
Name the sub cellular structures where aerobic respiration takes place ?
Giveaways animal cells differ from plant cells ?
Give the differences of prokaryotic and eukaryotic cells
•prokaryotic cells are smaller
•prokaryotic cells have mitochondria
•prokaryotic cells don’t have a true nucleus
•prokaryotic cells have circular DNA
Why Microsoft should be used to look at the internal structure of a chloroplast?
What is the function of a chloroplast ?
They absorb light needed for photosynthesis to make food for the plant
What s the unction of a ribosome ?
They’re where proteins are made in a cell
What type of organism are plants and animals?
Why is an Electron microscope better than a light microscope?
Has a much higher magnification and resolving power
this means it can be used to study cells in much finer details
this has enabled biologist to see and understand Mossop cellular structures
Describe the nucleus
Contains genetic material that controls activities of the cell
These are where most of the reactions for aerobic respiration take place
respiration transfers energy that the cell needs to work
Describe the cytoplasm
I gel like substance where most of the chemical reactions happen
it contains enzymes that control these chemical reactions
Describe the cell membrane
Holds the cell together and controls what goes in and out
These are where proteins are made in the cell
Describe the cell wall
Original wall made of Celulose
it supports and strengthens the cell
Describe the permanent vacuole
Contains cell sap a weak solution of sugar and salt
These are where photosynthesis occurs which makes the food for the plant
they contain green substance like chlorophyll
which absorbs light needed for photosynthesis
What is the resolution of the microscope?
The ability to distinguish between two points
so higher resolution give the sharper image
Why do we add a drop of iodine solution when observing a slight?
It stings and highlights objects by adding colour to them
