Cell Skills Lab: Slides, Models and Health Connections

Section A: Core Practice

Question 1mcq

Which statement best explains: Prepare slides to observe cells?

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

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

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

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

Question 2mcq

A student is revising [Formative] Cell Inquiry and Applications. Which idea is most accurate?

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

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

C.Staining and careful slide preparation make cells easier to observe.

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

Question 3mcq

Which answer shows correct understanding of prepare slides to observe cells?

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

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

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

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

Question 4mcq

Which statement should a Grade 9 student remember about Prepare slides to observe cells?

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

B.Staining and careful slide preparation make cells easier to observe.

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

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

Question 5mcq

Which statement best explains: Design models of cell organelles?

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

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

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

D.Epithelial tissues cover, line and protect body surfaces.

Question 6mcq

A student is revising [Formative] Cell Inquiry and Applications. Which idea is most accurate?

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

B.Nervous tissue receives and transmits impulses for coordination.

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

D.Models are useful when labels and materials show structure-function relationships.

Section B: Application Check

Question 7mcq

Which answer shows correct understanding of design models of cell organelles?

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

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

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

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

Question 8mcq

Which statement should a Grade 9 student remember about Design models of cell organelles?

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

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

C.Models are useful when labels and materials show structure-function relationships.

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

Question 9mcq

Which statement best explains: Connect cell biology to human health?

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

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

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

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

Question 10mcq

A student is revising [Formative] Cell Inquiry and Applications. Which idea is most accurate?

A.Mitochondrial problems, membrane transport issues and uncontrolled division link cells to health.

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

C.Nervous tissue receives and transmits impulses for coordination.

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