The Four Eukaryote Groups — exam questions
10 original Incandio exam-style questions on the Four Eukaryote Groups, 21 marks, about 21 minutes of writing. Each one carries the command word, the tariff and the specification statement it assesses, exactly as a paper presents them. This is an original Incandio practice question, written to reflect the structure and demands of the qualification. It is not an official Pearson Edexcel past-paper question.
This is the practice set for The Four Eukaryote Groups — the lesson that teaches it. Read the lesson first if the idea is new; come here when you want to find out whether you can turn it into marks. Completely free, no account needed to read.
What these questions ask of you
8 command words run through this set, and on Pearson Edexcel International GCSE Biology each one means something precise. Answering the wrong command is the commonest way a candidate who understands the lesson still loses the mark.
- Which (1 mark)
- one option chosen from the set given
- Name (1–2 marks)
- the correct term, spelled recognisably
- State (1 mark)
- one precise fact, no justification
- Describe (2–4 marks)
- developed, linked statements of WHAT happens — no reason required, but detail is Misread as: giving one bare statement where the tariff asked for a developed account
- Explain (2–4 marks)
- a causal chain — WHY it happens, each link a separate marking point Misread as: describing what happens without giving the reason it happens
- Compare (2–4 marks)
- explicit points of similarity or difference, each naming BOTH things
- Give (1–2 marks)
- a short factual answer drawn from recall or from the data
- Suggest (1–3 marks)
- a plausible answer applying taught biology to a situation not taught
Assessed on Paper 1 (4BI1/1B) and Paper 2 (4BI1/2B), against AO1, AO2.
Where these sit in the specification
Pearson Edexcel International GCSE Biology (4BI1) — statement 1.2. Incandio is aligned to this specification; it is not published by, endorsed by or affiliated with Pearson, and it reproduces none of Pearson's wording.
The 10 questions
Answer them on paper, then open the lesson's exam practice to have them marked. The mark scheme, the accepted and rejected answers and the annotated model answer are in Incandio and are not printed here — an answer beside its question is not practice.
-
Table 1 — features observed in organism Q, found growing on a fallen log. Feature Observation Nucleus present in every cell Cell wall present Chloroplasts absent Body form a network of fine threads spreading through the wood Source of nutrients the dead wood the threads grow through (a)
(1)Give
Give the feature in Table 1 that shows organism Q is a eukaryote.
Table 1 — features observed in organism Q, found growing on a fallen log. Feature Observation Nucleus present in every cell Cell wall present Chloroplasts absent Body form a network of fine threads spreading through the wood Source of nutrients the dead wood the threads grow through (b)
(3)Suggest
Suggest which of the four eukaryote groups organism Q belongs to, using the evidence in Table 1.
Table 1 — features observed in organism Q, found growing on a fallen log. Feature Observation Nucleus present in every cell Cell wall present Chloroplasts absent Body form a network of fine threads spreading through the wood Source of nutrients the dead wood the threads grow through (c)
(2)Explain
Explain why finding a cell wall is not on its own enough to place an organism in the plant group.
Table 1 — features observed in organism Q, found growing on a fallen log. Feature Observation Nucleus present in every cell Cell wall present Chloroplasts absent Body form a network of fine threads spreading through the wood Source of nutrients the dead wood the threads grow through (Total for Question 1 = 6 marks)
-
(1)Which
Which group contains organisms whose bodies are made of a mycelium of hyphae?
Group A plants B animals C fungi D protoctists (Total for Question 2 = 1 mark)
-
(1)Name
Name the carbohydrate that fungi and animals both use as a storage compound.
(Total for Question 3 = 1 mark)
-
(1)State
State one feature of Amoeba that shows it is a protoctist and not a bacterium.
(Total for Question 4 = 1 mark)
-
(3)Describe
Describe how a fungus such as Mucor obtains its nutrients.
(Total for Question 5 = 3 marks)
-
(2)Explain
Chlorella is a single-celled organism containing chloroplasts. Explain why it is classified as a protoctist rather than as a plant.
(Total for Question 6 = 2 marks)
-
(3)Compare
Compare the way a fungus and a flowering plant obtain the organic molecules they need.
(Total for Question 7 = 3 marks)
-
(4)Compare
Compare a plant cell with a fungal cell and an animal cell, in terms of the structures each one has.
(Total for Question 8 = 4 marks)
Have them marked, then defend the answer
Practice tells you the mark; teaching it back tells you whether you understand it. On Incandio a topic counts as mastered only once you have taught it and defended it.
- Mark these questions — 10 questions, marked on Incandio against the authored scheme, with the mistake you actually made named.
- Teach it — explain the Four Eukaryote Groups to Ember, an AI pupil who does not have it yet and asks the awkward question.
- Defend it — argue it against Carl Linnaeus over three rounds, marked against descriptors you can read first.
