Interactive biology worksheet for matching cell organelles to their functions.

The task is to match the cell organelles with their respective functions. Below is the solution with explanations for each match:

Left Column: Functions

1. Secretory and membrane protein synthesis
- Match: Rough Endoplasmic Reticulum (RER)
- Explanation: The Rough Endoplasmic Reticulum is studded with ribosomes, which are responsible for synthesizing proteins. Proteins destined for secretion or insertion into membranes are synthesized here.

2. Structures for locomotion
- Match: Flagella
- Explanation: Flagella are whip-like structures that help cells move. They are used for locomotion in cells like sperm cells and some bacteria.

3. ATP synthesis; produces energy
- Match: Mitochondrion
- Explanation: Mitochondria are often called the "powerhouses of the cell" because they produce ATP (adenosine triphosphate) through cellular respiration, which is the primary source of energy for the cell.

4. Hydrogen Peroxide scavenging
- Match: Peroxisome
- Explanation: Peroxisomes contain enzymes that break down harmful substances, including hydrogen peroxide, converting it into water and oxygen.

5. Spindle fibre formation in animal cells
- Match: Centriole in animal cell
- Explanation: Centrioles play a crucial role in organizing the microtubules that form the mitotic spindle during cell division in animal cells.

6. Protection, Structure, and support
- Match: Cell wall in plant cell
- Explanation: The cell wall in plant cells provides structural support, protection, and maintains the shape of the cell. It is made primarily of cellulose.

7. Site of ribosomal subunit synthesis
- Match: Nucleolus
- Explanation: The nucleolus is a dense region within the nucleus where ribosomal RNA (rRNA) is synthesized and ribosomal subunits are assembled.

8. Protein sorting and targeting
- Match: Golgi apparatus
- Explanation: The Golgi apparatus modifies, sorts, and packages proteins and lipids for delivery to their final destinations within or outside the cell.

Right Column: Functions

9. Structural framework of the cell
- Match: Cytoskeleton
- Explanation: The cytoskeleton is a network of protein filaments (microtubules, microfilaments, and intermediate filaments) that provides structural support, helps maintain cell shape, and aids in intracellular transport.

10. Selectively permeable to molecules
- Match: Plasma membrane
- Explanation: The plasma membrane regulates the movement of substances in and out of the cell. It is selectively permeable, allowing certain molecules to pass while blocking others.

11. Site of Photosynthesis
- Match: Chloroplast in plant cell
- Explanation: Chloroplasts are the sites of photosynthesis in plant cells. They contain chlorophyll, which captures light energy to convert carbon dioxide and water into glucose and oxygen.

12. Extracellular and Intracellular digestion
- Match: Vacuoles in plant cell
- Explanation: Vacuoles in plant cells store nutrients, waste products, and other substances. They can also participate in extracellular and intracellular digestion by breaking down materials.

13. Intracellular digestion and autophagy
- Match: Lysosome in animal cell
- Explanation: Lysosomes contain digestive enzymes that break down macromolecules, cellular debris, and foreign particles. They are involved in intracellular digestion and autophagy (self-digestion).

14. Lipid biosynthesis and drug detoxification
- Match: Smooth Endoplasmic Reticulum (SER)
- Explanation: The Smooth Endoplasmic Reticulum is involved in lipid synthesis, carbohydrate metabolism, and the detoxification of drugs and poisons.

15. Protein synthesis
- Match: Ribosomes
- Explanation: Ribosomes are the sites of protein synthesis. They read mRNA and assemble amino acids into proteins.

16. Contains genetic material DNA
- Match: Nucleus
- Explanation: The nucleus is the control center of the cell and contains the cell's DNA, which carries the genetic information necessary for the cell's functioning and reproduction.

Final Matched List:

- Secretory and membrane protein synthesis → Rough Endoplasmic Reticulum
- Structures for locomotion → Flagella

- Protection, Structure, and support → Cell wall in plant cell
- Site of ribosomal subunit synthesis → Nucleolus
- Protein sorting and targeting → Golgi apparatus
- Structural framework of the cell → Cytoskeleton
- Selectively permeable to molecules → Plasma membrane
- Site of Photosynthesis → Chloroplast in plant cell
- Extracellular and Intracellular digestion → Vacuoles in plant cell
- Intracellular digestion and autophagy → Lysosome in animal cell
- Lipid biosynthesis and drug detoxification → Smooth Endoplasmic Reticulum
- Protein synthesis → Ribosomes
- Contains genetic material DNA → Nucleus
