Cell Explorer: Discovery, Types and Life Units

Section A: Core Practice

Question 1mcq

Which statement best explains: Explain discovery of cell?

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

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

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

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

Question 2mcq

A student is revising Cell Discovery and Types. Which idea is most accurate?

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

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

C.Robert Hooke observed cork cells and microscopy opened cell biology.

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

Question 3mcq

Which answer shows correct understanding of differentiate plant and animal cells?

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

B.Nervous tissue receives and transmits impulses for coordination.

C.Striated muscles are usually voluntary, smooth muscles are involuntary and cardiac muscle works in the heart.

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

Question 4mcq

Which statement should a Grade 9 student remember about Differentiate plant and animal cells?

A.Plant and animal cells share basic parts but differ in visible structures and functions.

B.Cell biology connects with health because diseases can affect organelles, membranes, DNA or cell division.

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

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

Question 5mcq

Which statement best explains: Differentiate prokaryotic and eukaryotic cells?

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

B.Tissues allow division of labour in multicellular organisms.

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

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

Question 6mcq

A student is revising Cell Discovery and Types. Which idea is most accurate?

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

B.Cells are functional units because life processes occur inside cells.

C.A nucleus and membrane-bound organelles help identify eukaryotic cells.

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

Section B: Application Check

Question 7mcq

Which answer shows correct understanding of explain cell as structural unit of life?

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

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

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

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

Question 8mcq

Which statement should a Grade 9 student remember about Explain cell as structural unit of life?

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

B.Tissues and organs are formed from organised groups of cells.

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

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

Question 9mcq

Which statement best explains: Explain cell as functional unit of life?

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

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

C.Cells are functional units because life processes occur inside cells.

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

Question 10mcq

A student is revising Cell as Life Unit. Which idea is most accurate?

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

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

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

D.Cellular activities support growth, repair, energy release and survival.

Question 11mcq

Which statement should a Grade 9 student remember about Explain discovery of cell?

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

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

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

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

Question 12mcq

Which statement best explains: Differentiate plant and animal cells?

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

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

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

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