QuestionAnswer
Which microscope magnifies 1000x and gives a 2D image? Light
What are the advantages of a light microscope? Views live cells, portable
Which microscope magnifies 1000000x? Electron
What is the biggest disadvantage of the electronic microscope? Can only view dead cells
Which microscope produces 3D images? Laser
Which 3 structures are found in animal cells? Nucleus, cell membrane, cytoplasm
With three structures are found in plant cells but not in animal cells? Vacuous, chloroplast, cell wall
Where chemical reactions take place Cytoplasm
Controls what enters and leaves the cell Cell membrane
Contains DNA Nucleus
Where photosynthesis takes place Cloroplast
Stores cell sap Vacuole
Made of cellulose, gives the cell shape and sipport Cell wall
Specialised cell that carries oxygen Red blood cell
Adaptation of red blood cells Large surface area, no nucleus
Specialised cell that absorbs water into the roots Root hair cell
Adaptation of root hair cells Large surface area, no chloroplasts
Specialised cell found lining the airways Ciliated epithelial cells
Adaptations of ciliated epithelial cells Hair - like cilia to move mucus
Specialised cell that is the male gamete Sperm
Adaptations of sperm cells Tail to swim, special coating on its head to burrow into the egg
Specialised cell that is found in the leaf Palisade cell
Adaptations of the palisade cell Large number of chloroplasts, large vacuole to push chloroplasts close to cell membrane to absorb more light

How bacteria reproduce Splitting in half
Structure of a virus Protein coat and a strand of DNA
How do viruses reproduce? Inside a host cell
Structure of unicellular algae
How do algae reproduce? Either as asexualy by producing spores or sexually by fusion of gametes
Structure of yeast
How yeast cells reproduce Budding
Definition of a stem cell Undifferentiated cell that can develop into many different specialised cells
Two places where we can get human stem cells from Embryos or bone marrow
Why is stem cell research controversial? Human embryos ate destroyed
Why are bone marrow stem cells a good choice Less chance of rejection
Location of stem cells in plants Meristems
Cell wall, cell membrane, cytoplasm, nucleus
Two types of cell division Mitosis & meiosis
Number of daughter cells produced by mitosis 2
Number of daughter cells produced my meiosis 4
Daughter cells produced by mitosis are genetically ..... Identical
Daughter cells produced by meiosis are genetically... Different
Function of mitosis Growth and replace damaged cells
Function of meiosis Producing gametes
