Cells + cell cycle Flashcards
What do cells make
ATP
How small are cells
smallest functional unit
When cells group what do they form
tissues
when tissues group what do they form
organs
What do cells synthesise
new substances
e.g - proteins, peptides, sugars, fats, DNA, RNA
what do cells produce and secrete
specialised substances
what do cells do to perform specialist tasks
differentiation
how do cells pass on genetic material
grow + divide
what types of cells can stem cells become
- muscle cells
- sex cells
- immune cells
- epithelial cells
- nervous cells
- blood cells
- bone cells
- fat cells
what is the cell membrane structure
phospholipid bilayer
functions of cell membrane
- permeable
- protection
- regulation
- communication
- identity
what does a nucleus contain
genetic material
what is nucleus made of
- nuclear envelope
- nucleolus
- nuclear pores
what is role of mitochondria
ATP synthase + production
what is a mitochondria made of
- matrix
- inter-membrane space
- inner and outer membrane
- DNA
- cristae
- ribosomes
- granules
what is the role of ribosomes
protein synthesis
what is the role of SER+RER
assemble, package and release proteins
what is the role of the golgi apparatus
moves proteins into vesicle for transportation out of the cell
cells have
- cytoskeleton
- microfilaments
- microtubules
- centrosomes
- cell extensions
