Biology paper 1 GCSE AQA (Triple) Final
Exam And Correct Answers.
Differentiation - Answer Process by which a cell changes to become specialised for its job
eukaryotic cells - Answer complex and includes all animal and plant cells
prokaryotic cells - Answer Smaller and simple, single-celled organism
nucleus - Answer contains genetic material that controls the activties of the cell
mitochondria - Answer where the reactions for aerobic respiration takes place
cytoplasm - Answer gel-like substance where most of the chemical reactions happen
contains enzymes that control these chemical reactions
cell membrance - Answer holds the cell together and controls what goes in and out of the cell
ribosomes - Answer where proteins are made in the cell
Rigid cell wall - Answer made of cellulose to support the cell and strengthen it
permanent vacuole - Answer Contains cell sap, a weak solution of sugar and salts
chloroplasts - Answer Where photosynthesis occurs, which makes food for the plants.
Contains a green substance called chlorophyll which absorbs the light needed for photosynthesis
bacteria are... - Answer prokaryotes
, Plasmids - Answer small rings of DNA
Light microscopes - Answer Uses light and lenses to form an image of a specimen and magnify
Lets us see large subcellular structures like nuclei
Electron microscope - Answer uses electrons instead of light to form an image
Higher magnification than light microscopes
Magnification - Answer Image size/real size
Fine adjustment knob (on a light microscope) - Answer Adjusts focus
Coarse adjustment knob - Answer Moves the stage up to just below the objective lens
sperm cells - Answer specialised for reproduction
nerve cells - Answer specialised for rapid signaling
muscle cells - Answer Specialised for contraction
root hair cells - Answer specialised for absorbing water and minerals
embryonic stem cells - Answer Can turn into ANY type of cell
can be used to replace faulty cells in old people
chromosomes - Answer contain genetic material
number of chromosomes - Answer 23 pairs
