Cell Skills Lab: Slides, Models and Health Connections

Section A: Core Practice

Question 1mcq

Which statement best explains preparing slides to observe cells Focus on: Temporary mounts help observe cell structures under a microscope..?

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

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

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

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

Question 2mcq

A student is checking preparing slides to observe cells. Which statement is scientifically accurate Focus on: Staining and careful slide preparation make cells easier to observe..?

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

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

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

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

Question 3mcq

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

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

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

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

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

Question 4mcq

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

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

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

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

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

Question 5mcq

Which statement best explains cell organelle models?

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

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

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

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

Question 6mcq

A student is checking cell organelle models. Which statement is scientifically accurate Focus on: Models are useful when labels and materials show structure-function relationship.?

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

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.Cells were discovered after microscopes made tiny structures visible.

Section B: Application Check

Question 7mcq

Which answer shows correct understanding of cell organelle models?

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

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

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

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 cell organelle models?

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

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

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

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

Question 9mcq

Which statement best explains links between cell biology and health?

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

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

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

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

A student is checking links between cell biology and health. Which statement is scientifically accurate Focus on: Mitochondrial problems, membrane transport issues and uncontrolled division link.?

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

B.Nervous tissue receives and transmits impulses for coordination.

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.
