Answer
  • crystal violet and haematoxylin
  • crystal violet and metal
  • metals and haemotoxylin
  • crystal blue and crystal violet

Question 9

Question
The differences between gram positive and negative is that gram positive [blank_start]resists[blank_end] purple stains and has [blank_start]thick[blank_end] peptidoglycan whereas gram negative has [blank_start]thin[blank_end] peptidoglycan and [blank_start]absorbs[blank_end] the purple colour
Answer
  • resists
  • thick
  • thin
  • absorbs

Question 10

Question
The process of immunolabelling [blank_start]Unlabelled[blank_end] antibody [blank_start]binds[blank_end] to antigen then a secondary labelled [blank_start]antibody[blank_end] binds to the primary antibody and [blank_start]emits light[blank_end] as a marker
Answer
  • binds
  • Unlabelled
  • antibody
  • emits light

Question 11

Question
Two bacterial specialisations are [blank_start]pili[blank_end] and [blank_start]flagella[blank_end]. [blank_start]Pili[blank_end] is for adhesion and [blank_start]flagella[blank_end] is for movement
Answer
  • pili
  • flagella
  • Pili
  • flagella

Question 12

Question
Protists are [blank_start]unicellular[blank_end] organisms such as [blank_start]algae[blank_end] or amoeba
Answer
  • unicellular
  • multicellular
  • algae
  • sponges

Question 13

Question
Structure and function of fungi
Answer
  • have rigid cell walls
  • have no cell wall
  • have a cell membrane
  • made of microscopic filaments
  • are heterotrophs absobers
  • create molecules using enzymes
  • break down molceules using enzymes so they can be absorbed

Question 14

Question
3 types of plant tissues
Answer
  • ground tissue
  • vascular tissue
  • Dermal tissue
  • stem tissue
  • root tissue

Question 15

Question
Ground tissue is for [blank_start]support[blank_end] and [blank_start]energy storage[blank_end], vascular tissue is for [blank_start]transport of water and nutrients[blank_end] and dermal tissue is for [blank_start]protection[blank_end]
Answer
  • support
  • energy storage
  • transport of water and nutrients
  • protection

Question 16

Question
Epithelial cells are [blank_start]tightly packed[blank_end] cells which are [blank_start]specialised[blank_end]. They form a barrier and have [blank_start]absorbant[blank_end] properties and can facilitate absorbtion by [blank_start]microvilli[blank_end]
Answer
  • tightly packed
  • specialised
  • absorbant
  • microvilli

Question 17

Question
The two types of connective tissues are [blank_start]fibroblasts[blank_end] which are for [blank_start]support[blank_end] and secretion and [blank_start]leukocytes[blank_end] which are for [blank_start]defense[blank_end]
Answer
  • fibroblasts
  • support
  • leukocytes
  • defense

Question 18

Question
What are the intermediate filaments function?
Answer
  • to provide cell strength
  • to provide support
  • to provide protection
  • to provide defense
  • to provide nutrients

Question 19

Question
What processes occur in the nucleus?
Answer
  • DNA replication
  • DNA transcription
  • RNA transcription
  • RNA translation

Question 20

Question
What occurs when a large nucleolus or multiple nucleoli is present
Answer
  • A large nucleolus mean the cell is synthesising a large amount of protein
  • a large nucleolus mean the cell is synthesising large amounts of lipids

Question 21

Question
When DNA is highly condensed it is undergoing mitotic division
Answer
  • True
  • False

Question 22

Question
What is the role of lamins?
Answer
  • they help to organise chromatin
  • they help to organise DNA
  • they move organelles

Question 23

Question
What are nuclear pores ?
Answer
  • small channels for diffusion of water soluble molecules
  • large molecules for water soluble molecules
  • small channels for ion transport
  • small channels to allow for small molecules to pass
  • large channels for protein transportation

Question 24

Question
Facts about ribosomes
Answer
  • they occur freely in the cell
  • they occur attached to the rough ER
  • they occur attached to smooth ER
  • free ribosomes synthesise cytosolic proteins
  • free ribsomes synthesise mitochondria
  • attached ribosomes synthesise chloroplasts
  • free ribosomes synthesise chloroplasts and peroxisomes

Question 25

Question
