Question 1

Study the classification table below. Which one of the following can be placed in the same group of things as group A?

Accepted Answer

(3) Lizard. Group A consists of living things (Frog, Tree, Fern). Among the given options, a Lizard is a living thing. Car, Table, and Mobile phone are non-living things.

Question 2

The table below show 3 things, L, M and N and their characteristics. A tick (√) shows that the thing has the characteristic. Based on the table above, which of the following statements below describes L, M and N correctly?

Accepted Answer

(1) N is a non-living thing.. Living things generally possess characteristics such as needing air, food, and water, moving, responding to changes, and growing.
- L shows all characteristics, indicating it is a living thing (like an animal).
- M needs air, food, water, and grows, but does not move or respond to changes, typical of a living plant.
- N shows none of these characteristics.
Therefore, N is a non-living thing. Statement (1) is correct.

Question 3

There are 4 statements, A, B, C and D made about living things. A They have young. B They can reproduce. C They come in different sizes and shapes. D They feed on other living things for food. Which statements state the similarities between plants and animals?

Accepted Answer

(4) A, B and C only. Let's evaluate each statement for both plants and animals:
- A (They have young): Both plants (seedlings) and animals (offspring) produce young.
- B (They can reproduce): Both plants and animals reproduce to continue their species.
- C (They come in different sizes and shapes): Both kingdoms exhibit vast diversity in size and shape.
- D (They feed on other living things for food): This is true for animals (heterotrophs) but not for most plants (autotrophs, which make their own food).
Thus, statements A, B, and C describe similarities between plants and animals.

Question 4

Which of the following statements about a non-flowering plant is not true?

Accepted Answer

(4) It has roots, stems, leaves and seeds.. Non-flowering plants (like ferns, mosses, conifers) do not produce flowers or fruits. Many, like ferns and mosses, reproduce by spores. While some non-flowering plants (like ferns and conifers) have roots, stems, and leaves, they do not produce seeds in the way flowering plants do; seeds are characteristic of seed plants (which can be flowering or non-flowering like conifers, but the general group of non-flowering plants, especially ferns and mosses, do not have seeds). Therefore, the statement 'It has roots, stems, leaves and seeds' is generally not true for non-flowering plants as a category, particularly the 'seeds' part for common examples like ferns.

Question 5

The characteristics of living thing K are listed below. Which of the following represents living thing K?

Accepted Answer

(3) Mushroom. The characteristics provided describe a mushroom:
- 'Has a cap, stalk and gills': This is the typical structure of a mushroom.
- 'Can be seen with naked eyes': Mushrooms are macroscopic fungi.
- 'Feed on dead and living organisms': Mushrooms are decomposers (saprophytes) or parasites, obtaining nutrients from other organisms.
Yeast and bacteria are microscopic. While bread mould can be seen as a colony, its individual structures are microscopic, and it doesn't typically have a distinct 'cap, stalk and gills'.

Question 6

Study the diagram below. They are living things that

Accepted Answer

(2) can be useful to us. The diagrams show Fungus (mushrooms) and Bacteria. Both are living things.
- (1) Neither fungi nor bacteria produce flowers.
- (2) Both fungi (e.g., yeast in baking) and bacteria (e.g., in digestion, making yogurt) can be useful to humans.
- (3) Fungi reproduce by spores, but bacteria reproduce by binary fission.
- (4) Bacteria are microorganisms, but macroscopic fungi like mushrooms are not always microorganisms.
Therefore, the statement that applies to both is that they can be useful to us.
