The control center of the cell, containing DNA which determines the cell's characteristics and functions.

A network of interconnected sacs that acts as a transportation system within the cell. It facilitates the synthesis and movement of proteins and lipids.

A type of ER with ribosomes attached to its surface. Involved in protein synthesis and transport.

A type of ER without ribosomes. Involved in lipid synthesis, detoxification, and transport.

A liquid-filled sac within the cell that stores cell sap and other materials.

Found in plant cells, it's a strong, rigid outer layer made of cellulose fibers, providing support and maintaining shape.

The jelly-like substance that fills the cell. It contains many cell components and acts as a medium for all the cell's chemical processes.

A large, liquid-filled sac found in plant cells. It plays a vital role in maintaining cell turgor (rigidity) and stores substances.

This double-layered membrane surrounds the vacuole, regulating the flow of substances in and out.

Green-colored organelles found in plant cells. They capture sunlight and convert it into chemical energy during photosynthesis.

A single-celled organism capable of independent life, carrying out all life functions within a single cell.

A type of movement used by Amoeba sp. where it extends cytoplasm-filled projections called pseudopods to move.

The ability of a living organism to react to changes in its environment or internal state.

Tiny hair-like structures on the surface of some cells, like Paramecium, used for movement.

A process where an organism takes in nutrients for growth and energy.

A specialized organelle in Paramecium that regulates water balance within the cell. It removes excess water from the cytoplasm, preventing the cell from bursting.

Amoeba uses temporary finger-like extensions of its cytoplasm called pseudopodia to move around and engulf food.

When conditions become unfavorable, Paramecium reproduces sexually through conjugation. This process involves the exchange of genetic material between two individuals, leading to genetic variation in offspring.

The oral groove is a funnel-shaped structure in Paramecium that directs food towards the cell's interior for digestion.

If Paramecium is placed in a concentrated salt solution, water will move out of the cell due to osmosis. This will cause the contractile vacuole to become smaller as it works harder to remove the excess water.
