Section A: Core Practice

Question 1mcq

Which statement best explains: Identify nucleus and its role?

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

B.The nucleus controls cell activities and contains genetic material.

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

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

Question 2mcq

A student is revising Cell Organelles and Functions. Which idea is most accurate?

A.Mitosis supports growth and repair; meiosis supports gamete formation and variation.

B.The nucleus stores instructions that guide cell function and inheritance.

C.A good cell model represents organelles and connects each structure with its function.

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

Question 3mcq

Which answer shows correct understanding of identify nucleus and its role?

A.Xylem transports water and minerals, while phloem transports food.

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

C.The nucleus controls cell activities and contains genetic material.

D.Muscles, bones, cartilage and posture support fitness, yoga and healthy movement.

Question 4mcq

Which statement should a Grade 9 student remember about Explain mitochondria and chloroplast functions?

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

B.Tables, diagrams and graphs help represent tissue experiment observations clearly.

C.Mitochondria release energy, while chloroplasts carry out photosynthesis.

D.Muscles, bones, cartilage and posture support fitness, yoga and healthy movement.

Question 5mcq

Which statement best explains: Explain mitochondria and chloroplast functions?

A.Meristematic tissues divide actively; permanent tissues are specialised for functions.

B.Nervous tissue receives and transmits impulses for coordination.

C.It applies only to non-living objects, not cells or tissues.

D.Mitochondria are linked with respiration and chloroplasts with food making.

Question 6mcq

A student is revising Cell Organelles and Functions. Which idea is most accurate?

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

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

C.Mitochondria release energy, while chloroplasts carry out photosynthesis.

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

Section B: Application Check

Question 7mcq

Which answer shows correct understanding of explain endoplasmic reticulum and vacuoles?

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

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

C.Temporary mounts help observe cell structures under a microscope.

D.Exercise, posture, nutrition and injury prevention help care for the musculoskeletal system.

Question 8mcq

Which statement should a Grade 9 student remember about Explain endoplasmic reticulum and vacuoles?

A.ER forms internal channels and vacuoles store cell sap, food or wastes.

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

C.Tissue structure is adapted to the function it performs.

D.Xylem transports water and minerals, while phloem transports food.

Question 9mcq

Which statement best explains: Explain endoplasmic reticulum and vacuoles?

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.Tables, diagrams and graphs help represent tissue experiment observations clearly.

Question 10mcq

A.Tissue structure is adapted to the function it performs.

B.The plasma membrane is selectively permeable, while the cell wall is more rigid.

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

D.Connective tissues support, bind, protect and transport materials.

Question 12mcq

Which statement should a Grade 9 student remember about Compare plasma membrane and cell wall?
