Cell Structure and Functions Quiz

What is the primary function of the cell membrane?

Which organelle is responsible for respiration and energy release?

What is the function of the cell wall in plant cells?

What distinguishes the vacuole in mature plant cells compared to vacuoles in animal cells?

Which cellular structure is primarily involved in photosynthesis?

Which organelle is often abundant in active cells like liver cells?

In which type of cells are chloroplasts found?

What is contained within the large central vacuole of a mature plant cell?

Which of the following statements about ribosomes is true?

Cell Membrane

Forms a boundary between the cell's interior and its environment.
Regulates movement of substances in and out of the cell.

Cytoplasm

Site of all cellular activities.
Contains organelles like mitochondria and ribosomes, as well as food reserves (glycogen, starch, oil droplets).
Appears granular in structure.

Mitochondrion

Organelle where respiration occurs, providing energy for cellular functions.
Active cells, such as liver cells, have numerous mitochondria.
Structure is typically not clearly visible under light microscopy.

Cell Wall

Nonliving layer external to the cell membrane in plant cells.
Permits free passage of liquids and dissolved substances.
Provides shape and structural support to plant cells.
Absent in animal cells.

Vacuole

Mature plant cells contain a large central vacuole filled with cell sap (dilute solution of salts and sugars).
May also contain pigments.
Animal cells may have small, temporary vacuoles.

Chloroplast

Organelle that contains the green pigment chlorophyll found in plant cells.
Abundant in palisade cells of leaves, where photosynthesis takes place.
Not present in animal cells.

Test your knowledge on the essential components of a cell, including the cell membrane, cytoplasm, and mitochondria. This quiz will cover their functions and importance in cellular activities, helping you understand these critical biological structures.
