Across
1. The powerhouse of the cell, responsible for producing energy in the form of ATP.
Answer: Mitochondria
Mitochondria, often referred to as the “powerhouses of the cell,” are essential for cellular energy production. They are responsible for the process of cellular respiration, where glucose is broken down to generate ATP, the primary energy currency of the cell.
5. The “brain” of the cell, containing DNA and controlling cellular activities.
Answer: Nucleus
The nucleus is the cell’s control center, housing the genetic material, DNA, in the form of chromosomes. DNA contains the blueprint for all cellular activities, including protein synthesis and cell division. It directs and coordinates all cellular functions.

9. A network of interconnected membranes that function in protein synthesis, lipid synthesis, and detoxification.
Answer: Endoplasmic reticulum (ER)
The ER is an extensive network of interconnected membranes that forms a labyrinthine structure within the cell. It plays a crucial role in protein synthesis, folding, and modification, lipid metabolism, and detoxification processes.
11. The “garbage disposal” of the cell, responsible for breaking down waste products and worn-out organelles.
Answer: Lysosomes
Lysosomes are membrane-bound organelles containing digestive enzymes. These enzymes break down waste products, cellular debris, engulfed bacteria, and old or damaged organelles, ensuring the efficient removal of cellular waste.
Down
2. A small, dense structure inside the nucleus where ribosomes are produced.
Answer: Nucleolus
The nucleolus is a prominent structure within the nucleus, responsible for the production of ribosomes, essential components for protein synthesis. The nucleolus is a vital site for the synthesis of ribosomal RNA (rRNA), which combines with proteins to form ribosomes.
3. Small, spherical organelles that help in protein synthesis.
Answer: Ribosomes
Ribosomes, the protein factories of the cell, are responsible for translating the genetic code from messenger RNA (mRNA) into proteins. They are composed of ribosomal RNA (rRNA) and proteins and are found in the cytoplasm, attached to the ER, or within mitochondria.
4. A network of protein filaments that provides structure and support to the cell.
Answer: Cytoskeleton
The cytoskeleton is a complex network of protein filaments that provides structural support, maintains cell shape, and facilitates cellular movement. It is composed of three main types of filaments: microtubules, microfilaments, and intermediate filaments, each with unique roles in cell organization and function.
6. A stack of flattened, membrane-bound sacs that modify and package proteins.
Answer: Golgi apparatus
The Golgi apparatus, often called the “post office” of the cell, is a stack of flattened membrane-bound sacs. It receives proteins from the ER, modifies them, sorts them, and packages them into vesicles for delivery to their final destinations within or outside the cell.
7. Fluid-filled spaces within the cytoplasm that store substances, including water and nutrients.
Answer: Vacuoles
Vacuoles are large, fluid-filled sacs surrounded by a single membrane. They are particularly prominent in plant cells and play a vital role in regulating cell turgor pressure, storing nutrients and water, and even helping in waste disposal.
8. Short, hair-like projections that help in movement.
Answer: Cilia
Cilia are short, hair-like projections found on the surface of some cells. Their rhythmic beating motion helps in the movement of fluids, such as in the respiratory tract, where they help to sweep away mucus and debris.
10. Long, whip-like projections that allow for locomotion.
Answer: Flagella
Flagella are long, whip-like projections that are typically used for locomotion. They are found in some bacteria and eukaryotic cells, such as sperm cells, and their wave-like motion propels the cell through its environment.
