Cell Theory and Structure Review - Year 11 Biology Module 1

Which of the following are common among all cells

• Golgi apparatus, Endoplasmic Reticulum, Cilium

• Cell wall, Vacuole, Nucleus

• DNA, Cell membrane, Ribosomes

• Mitochondria, Chloroplast, Cytoplasm

Cell theory states that (select all that apply)

• Cells are the basic unit of life

• Cells are a product of spontaneous generation

• All organism are made of cells

• All cells come from pre-existing cells

Why are cells limited in size?

• The cell membranes can't contain lots of organelles without bursting

• Cell size is limited to depending on the amount of DNA that kind of cell possesses

• Cell size is limited by the available space surrounding a cell

• Cells need to exchange molecules across their membrane to survive, so their size is limited by their SA:V ratio

The cell membrane has which of the following characteristics

• Hydrophobic lipid heads

• 2 layers of phospholipids

• A ridged and immovable structure

• Embedded proteins which serve as transport channels

Ribosomes are ...

• The sites of mRNA translation

• Made of 3 subunits

• Always attached to the Endoplasmic Reticulum

• Not membrane bound

The organelle that recycles cell material, is the ...

• Centriole

• Cilium

• Cytoskeleton

• Lysosome

Thylakoid, Granum and Stroma are all parts of a ...

• Chloroplast

• Chlorophyll

• Cytoplasm

• Cytoskeleton

Which of the following cells could have a cell wall?

• 
• 
• 

Cellular respiration is to mitochondria as photosynthesis is to

• plants

• microtubules

• chloroplasts

• ribosomes

The cell membrane

• regulates what enters/leaves cell
• helps maintain homeostasis
• keeps contents of cell in place
• all of the above
