cell theory Answer: All living organisms are made up of cells
Cells are the smallest functioning unit of living organisms
All cells come from pre-existing cells
the characteristics of living organisms Answer: Movement - able to move towards
food and light
Sensitivity - sensitive to touch and moves away from danger
Growth - has the ability for cells to divide, grow and replace
Reproduce - can create an offspring
Exchange of gas - gases such as oxygen, carbon dioxide and nitrogen
Excretion - can excrete waste and get rid of toxins
Nutrition - is able to input nutrition and use its diet to grow/repair
Types of cells Answer: Prokaryotic - does not contain a nucleus or membrane
bound organelles. Unicellular. E.g. bacteria
Eukaryotic - contains a nucleus surrounded by a membrane. Contains membrane
bound organelles. E.g. animals, plants, fungi
Parts of Prokaryotic cell Answer: Cell wall- support and protection, found in plant
cell only
Cell membrane - flexible barrier that regulates movement of molecules in and out of
the cell, found in all cells

, Nucleus - holds DNA which controls cell activities.
Mitochondria - where energy ATP (energy currency for all cells) is produced from
glucose in cellular respiration
Chloroplast - site of photosynthesis to convert light energy into glucose.
Ribosome - site of protein synthesis
Cytosol - jelly fluid where many cell reactions happen
Parts of Eukaryotic cell Answer: Endoplasmic reticulum - transports materials within
the cell. Tubular tunnels, next to nucleus.
Golgi apparatus - packages materials for storage and secretion out of the cell. Close
to the cell membrane.
Vacuole - storage area for water, starch, oils etc. Found in plants/animals. Large in
plant cells.
Lysosomes - packets of enzymes (protein chemicals that break down substances)
that are released to kill old/malfunctioning cells
Centriole - structures involved in cell division
Characteristics of LIGHT microscopes Answer: Use lenses to bend light and
magnify images
Used to study dead or living cells in color
Cell movement can be studied. Can see cell wall, nucleus, cell membrane,
chloroplasts, cytosol; can see living cells if not stained
Characteristics of ELECTRON microscopes Answer: Uses electron beams focused
by electromagnets to magnify and resolve.
Requires cells to be killed and chemically treated before viewing, so no movement
can be seen.
