The diagram shows some parts of a plant cell. Which structure contains cell sap?

Here are the solutions to questions 9, 10, and 11:

Question 9:
The diagram shows the levels of classification of a human. The numbers 1, 2, and 3 represent the following levels:

• 1: Animalia is the Kingdom.
• 2: Primate is the Order.
• 3: Homo is the Genus.

Therefore, the levels represented by 1, 2, and 3 are Kingdom, Order, and Genus.
Let's examine the given options:
A Kingdom, class, species
B Kingdom, family, species
C phylum, order, genus
D phylum, order, species

Comparing our identified levels (Kingdom, Order, Genus) with the options:

• Option C contains "order" and "genus", which correctly match levels 2 and 3. While "phylum" is incorrect for level 1 (which should be Kingdom), this option has the most correct matches among the choices.

The best fit among the given options is C.
The final answer is $\boxed{\text{C}}$

Question 10:
The cell theory is a fundamental concept in biology. It states that all living organisms are composed of cells, cells are the basic units of life, and new cells arise from pre-existing cells.

• A cells are eukaryotic (describes a cell type, not the theory)
• B cells are prokaryotic (describes a cell type, not the theory)
• C cells are building blocks of organisms (this is a core tenet of the cell theory)
• D cells are food for all living organisms (incorrect)

The phrase that best describes the cell theory is that cells are the building blocks of organisms.
The final answer is $\boxed{\text{C}}$

Question 11:
The diagram shows a plant cell with various labeled structures:

• A points to the nucleus.
• B points to the large central vacuole.
• C points to the cytoplasm.
• D points to the cell wall.

Cell sap is the fluid found within the large central vacuole of a plant cell. Therefore, structure B contains cell sap.
The final answer is $\boxed{\text{B}}$
