PAPER 2026 COMPLETE QUESTIONS AND
VERIFIED ANSWERS
◉ Are plant cells eukaryotic or prokaryotic? Answer: Eukaryotic
◉ Are bacteria cells prokaryotic or eukaryotic? Answer: Prokaryotic
◉ are prokaryotic cells much bigger or smaller than eukaryotic?
Answer: much smaller
◉ Parts of a eukaryotic cell Answer: cell membrane, cytoplasm,
nucleus
◉ Parts of a prokaryotic cell Answer: cell wall
dna loop
cell membrane
cytoplasm
plasmids
◉ give 5 sub cellular structures that are found in both animal and
plant cells? Answer: -nucleus
,-cytoplasm
-cell membrane
-ribosomes
-mitochondria
◉ give 3 sub cellular structures that are found in plant cells but not
in animal plants? Answer: -cell wall
-chloroplasts
-permanent vacuole
◉ what the function of the nucleus ? Answer: contains genetic
material
◉ Function of cell membrane Answer: regulates what enters and
leaves the cell
◉ function of mitochondria Answer: cellular respiration
◉ function of chloroplast Answer: Contains chlorophyll which
absorbs light energy for photosyntheis
◉ cell wall function? Answer: provides support and protection
,◉ function of plasmids in bacteria cell? Answer: contains extra
genetic material that can help the bacteria cell survive
◉ What are plant cell walls made of? Answer: cellulose
◉ what is a plant cells permanent vacuole filled will? Answer: cell
sap
◉ give 2 differences between electron microscopes and light
microscopes? Answer: electron microscopes have a much higher
magnification and a much higher resolution than light microscopes
◉ what formula is used to calculate magnification of an image?
Answer: magnification = imagine size /real size
◉ give a brief method for using a light microscope to look at a
prepared slide Answer: USING A LIGHT MICROSCOPE TO LOOK AT A
PREPARED SLIDE
1)put the slide on the stage
2)select the lowest power lens
3)use the coarse adjustment knob to roughly focus the slide
4)use the fine adjustment(FA)knob to clearly focus the slide
5)switch to a higher power lens to increase magnification and
refocus with the FA knob
, ◉ give 3 things to remember when drawing cells observed through a
light microscope ? Answer: -use a pencil
-label the main structures
-include the magnification used
◉ what happens when cells differentiate? Answer: when cells
differentiate they develop different sub-cellular structures that make
them carry out certain functions
◉ how are animal cells different to plant cells in their ability to
differentiate? Answer: most animal cells differentiate early in
development and can't differentiate again
many plant cells can differentiate whenever they need to
◉ give 3 ways that a sperm cell is specialised to do its job Answer:
FUNCTION:to get DNA into egg cell
-tail for swimming
-lots of mitochondria to provide energy
-enzymes in head to digest egg cell membrane
◉ give 2 ways that a nerve cell is specialised to do its job Answer:
FUNCTION:carries messages around the body at high speed
