Answer
  • To hold DNA codes for amino acid sequences
  • Where rRNA transcription occurs
  • Aerobic respiration

Question 2

Question
The cell [blank_start]membrane[blank_end] controls which substances enter and exit a cell. It also helps to [blank_start]support[blank_end] the cell and [blank_start]maintain[blank_end] its [blank_start]shape[blank_end].
Answer
  • membrane

Question 3

Question
Mitochondria are the site of anaerobic respiration
Answer
  • True
  • False

Question 4

Question
What feature makes mitochondria suitable for respiration reactions?
Answer
  • A matrix, giving the mitochondrion a large surface area
  • Cristae, giving the mitochondrion a large surface area

Answer
  • golgi body
  • vesicle
  • cristae
  • rough endoplasmic reticulum

Question 6

Question

Question 7

Question
What is the role of the smooth endoplasmic reticulum?
Answer
  • Break down of lipids
  • Protein synthesis
  • Synthesis and transport of lipids
  • photosynthesis

Question 8

Question
Centrioles are arranged in two hollow cylinders, positioned perpendicular to each other. During cell division they organise the microtubules that form a spindle.
Answer
  • True
  • False

Question 9

Question
What is the function of the nucleolus?
Answer
  • Site of mRNA synthesis and transport
  • Synthesis tRNA
  • Where DNA is held
  • Synthesis of rRNA

Question 10

Question
What is a nuclear pore and what is it's purpose?
Answer
  • A small hole in the membrane of the nucleus which allows molecules such as mRNA in and out.
  • A large hole in the membrane of the nucleus which allows molecules such as mRNA in and out.
  • A small hole in the membrane of the nucleus which allows nutrients and oxygen in and out.

Question 11

Question
The nuclear envelope separates genetic material from the cytoplasm.
Answer
  • True
  • False

Question 12

Question
What are the main functions of a lysosome? (Tick 3)
Answer
  • To isolate digestive enzymes
  • To digest enzymes
  • To carry proteins to the golgi body
  • To digest material that has been taken into the cell
  • To digest unwanted DNA

Question 13

Question
What is the purpose of a vacuole?
Answer
  • To maintain osmotic pressure
  • To maintain atmospheric pressure
  • To maintain cell temperature

Question 14

Question
A stack of thylakoids is called a grain.
Answer
  • True
  • False

Question 15

Question
Where can thylakoids be found?
Answer
  • In a chloroplast
  • In a centriole
  • In a mitochondrion

Question 16

Question
[blank_start]Photosynthesis[blank_end] occurs in the chloroplast. This is because the thylakoids contain a photosynthetic pigment called [blank_start]chlorophyll[blank_end].
