Cell structure & magnification

Draw a animal cell/ list it’s structures

• nucleus

• Cytoplasm

• Cell membrane

• Mitochondria

• Ribosomes

What is a sub-cellular structure?

a component or part found within a cell,

• often referring to specialized organelles eg nucleus/ mitochondria.

• These structures perform specific functions essential for the cell's survival and operation, such as energy production or protein synthesis

Draw a plant cell/ list it’s (extra) structures

• Cell wall

• chloroplast

• Vacuole

what are plant & animals cells classified under?

Eukaryotic

What is bacteria classified under?

Prokaryotic cell

list the characteristics of prokaryotic cells compared to eukaryotic cells

• prokaryotic cells are much smaller in size

• They don’t contain mitochondria & chloroplasts

• Their genetic material isn’t in a nucleus → single DNA loop (chromosomal DNA)

• Has plasmids

What are plasmids?

• One or more small rings of DNA that can be transferred from one cell to another

• Allows bacteria cells to move genes from one cell to another

List the bacteria cell characteristics (& draw it)

• role of mitochondria & chloroplasts → taken over by cytoplasm

• One or more flagella (moves the bacterium)

• Plasmids DNA (replicated independently from chromosomal DNA)

• Chromosome DNA (long looped)

Formula for magnification

Size of image/ size of real image

Write out the number line for all units (cm to nm)

cm = 100

mm = 1000

(Micro) = 1 000 000

nm = 1 000 000 000
