Section A: Core Practice

Question 1mcq

Which statement best explains nucleus and genetic material Focus on: The nucleus controls cell activities and contains genetic material (while labelling a plant-cell diagram)?

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

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

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 2mcq

A student is checking nucleus and genetic material. Which statement is scientifically accurate Focus on: The nucleus stores instructions that guide cell function and inheritance..?

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

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

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

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

Question 3mcq

Which answer shows correct understanding of nucleus and genetic material?

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

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

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

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

Question 4mcq

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

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

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

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

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

Question 5mcq

Which statement best explains mitochondria and chloroplast functions?

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

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

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

D.Nervous tissue receives and transmits impulses for coordination.

Question 6mcq

A student is checking mitochondria and chloroplast functions. Which statement is scientifically accurate Focus on: Mitochondria release energy, while chloroplasts carry out photosynthesis (while comparing energy release and food making)?

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

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

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

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 endoplasmic reticulum and vacuoles Focus on: Endoplasmic reticulum helps transport materials, while vacuoles store substances (while labelling a plant-cell diagram)?

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

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

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

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

Question 8mcq

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

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

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

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

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

Question 9mcq

Which statement best explains endoplasmic reticulum and vacuoles?

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

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

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

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

Question 10mcq

A student is checking plasma membrane and cell wall differences. Which statement is scientifically accurate Focus on: The plasma membrane controls exchange; the cell wall gives support and protectio.?

A.The plasma membrane controls exchange; the cell wall gives support and protection.

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

C.Tissues allow division of labour in multicellular organisms.

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

Question 11mcq

Which answer shows correct understanding of plasma membrane and cell wall differences?

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

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

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

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

Question 12mcq

Which statement should a Grade 9 student remember about plasma membrane and cell wall differences Focus on: The plasma membrane controls exchange; the cell wall gives support and protectio.?

A.It is only a naming fact and does not affect how organisms work.

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

C.The plasma membrane controls exchange; the cell wall gives support and protection.

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