Section A: Core Practice

Question 1mcq

Which statement best explains diffusion and osmosis differences Focus on: Diffusion moves particles down a concentration gradient; osmosis is water moveme.?

A.Joints allow different types of movement, such as hinge and ball-and-socket movement.

B.Diffusion moves particles down a concentration gradient; osmosis is water movement through a semi-permeable membrane.

C.Apical meristem increases length, lateral meristem increases girth and intercalary meristem helps regrowth in grasses.

D.Prokaryotic cells lack a well-defined nucleus, while eukaryotic cells have one.

Question 2mcq

A student is checking diffusion and osmosis differences. Which statement is scientifically accurate Focus on: Osmosis is a special case involving water, while diffusion can involve different.?

A.Osmosis is a special case involving water, while diffusion can involve different particles.

B.Biomolecules such as proteins, lipids, carbohydrates and nucleic acids support cell structure and function.

C.Plant growth can be observed at regions such as root and shoot tips with active meristem.

D.Cells are the basic structural units because organisms are built from cells.

Question 3mcq

Which answer shows correct understanding of diffusion and osmosis differences?

A.Cells were discovered after microscopes made tiny structures visible.

B.Plant cells usually have a cell wall, chloroplasts and a large vacuole; animal cells do not.

C.Endoplasmic reticulum helps transport materials, while vacuoles store substances.

D.Diffusion moves particles down a concentration gradient; osmosis is water movement through a semi-permeable membrane.

Question 4mcq

Which statement should a Grade 9 student remember about osmosis through a semi-permeable membrane?

A.Biological organisation moves from cells to tissues, organs and organ systems.

B.Joints allow different types of movement, such as hinge and ball-and-socket movement.

C.Osmosis can be shown when water moves through a semi-permeable membrane into or out of cells.

D.It can be understood without looking at structure, function, or evidence.

Question 5mcq

Which statement best explains osmosis through a semi-permeable membrane?

A.Biomolecules such as proteins, lipids, carbohydrates and nucleic acids support cell structure and function.

B.Raisins swelling in water is evidence of water entering by osmosis.

C.It means all structures in living organisms perform exactly the same job.

D.Parenchyma stores, collenchyma gives flexible support and sclerenchyma gives strength.

Question 6mcq

A student is checking osmosis through a semi-permeable membrane. Which statement is scientifically accurate Focus on: Osmosis can be shown when water moves through a semi-permeable membrane into or (while explaining water movement in cells)?

A.Osmosis can be shown when water moves through a semi-permeable membrane into or out of cells.

B.Nervous tissue receives and transmits impulses for coordination.

C.It is mainly about memorising labels without explaining their role.

D.It can be understood without looking at structure, function, or evidence.
