◉ Eukaryotic. Answer: Has a nucleus, complex
◉ Prokaryotic. Answer: No nucleus, small and simple
◉ Subcellular structures. Answer: Different parts of a cell
◉ Nucleus. Answer: Contains genetic material and controls activities
◉ Cytoplasm. Answer: A gel like substance where most of the
chemical reactions take place
Contains enzymes
◉ cell membrane. Answer: In plant, animal and bacteria cells
Holds the cell together
controls which substances can enter or leave the cell
◉ Mitochondria. Answer: Powerhouse of the cell
,Where reactions for respiration takes place
◉ Ribosomes. Answer: In plant, animal and bacteria cells
site of protein synthesis
◉ Cell wall. Answer: Only in a plant cell
Made of cellulose
Supports and strengthens the cell
◉ Large Vacuole. Answer: Only in a plant cell
Contains cell sap
Maintains internal pressure
◉ Chloroplast. Answer: Site of photosynthesis
Contain chlorophyll
◉ Chromosomal DNA. Answer: In bacteria cell
Controls cells activities and replications
Floats free in cytoplasm
◉ Flagellum. Answer: In a bacteria cell
,A long, hairlike structure that grows out of a cell and enables the cell
to move.
Move away from toxins
◉ Plasmid DNA. Answer: In a bacteria cell
Small loops of extra DNA for things like drug resistance
◉ Specialised cells. Answer: Cells that are adapted to carry out a
particular function
◉ sexual reproduction. Answer: The nucleus of an egg cell fuses with
nucleus of a sperm cell to create a fertilised egg which develops into
an embryo
◉ Haploid nucleus. Answer: A nucleus containing a single set of
unpaired chromosomes
◉ Egg cell. Answer: Female reproductive cell
Carries female DNA
◉ How an egg cell is adapted to its function. Answer: 1) Contains
nutrients in the cytoplasm to feed embryo
2) Has a haploid nucleus
, 3)Straight after fertilisation the membrane changes structure to stop
any more sperm coming in
◉ Sperm cell. Answer: Male reproductive cell
Transports Male DNA
◉ How a sperm cell is adapted to its function. Answer: 1) Long tail-
swim to the egg
2) Lots of mitochondria in middle section to provide energy needed
to swim distance
3) Acrosome at front of head, where it stores enzymes needed to
digest way through membrane of egg cell
4) Haploid nucleus
◉ Ciliates epithelial cell. Answer: Lines the surfaces of organs
◉ How a ciliates epithelial cell is adapted to its function. Answer: 1)
Cilia to help move mucus in one direction
2) Allows mucus not to reach the lungs
◉ Resolution. Answer: How well a microscope distinguishes
between two points that are close together
