Controls what enters and exits the cell, holding its contents together.

Provides support and protection to plant cells, letting water in.

The cell's jelly-like substance that holds organelles.

Controls cell activities, contains DNA.

Produce proteins, essential for cell structure and function.

Synthesizes lipids (fats) and transports them within the cell, using vesicles to send them to the Golgi apparatus.

Processes, packages, and stores fats and proteins that were made in the ER. Exports them to other parts of the cell or outside.

Powerhouse of the cell. Makes energy (ATP) through cellular respiration, fueling the cell's activities.

Storage spaces for water, starch, and fats. Formed from cell membrane, Golgi, or ER.

Long, hollow tubes giving the cell shape and rigidity. Form cilia and flagella for movement.

Thin protein threads involved in cell movement, like muscle contraction in larger organisms.

Site of photosynthesis in plant cells. Contains chlorophyll to capture light energy and produce food (carbohydrates) for the plant.

Enzymes break down cells no longer needed by the organism, such as bacteria or cells forming tadpole tails.

A centriole is made up of microtubules.

Centrioles help separate chromosomes during cell division by forming a spindle shape.

Centrioles are found in pairs inside the centrosome.

All living organisms are composed of one or more cells.

The cell is the basic unit of life.

All cells arise from pre-existing cells.

The part of the microscope you look through to view the specimen.

Magnifies the specimen, with different lenses offering various magnifications.

A microscopy technique that illuminates the specimen from the side, creating a bright image against a dark background.

A microscopy technique that enhances the contrast of transparent specimens by exploiting the differences in refractive index, allowing detailed visualization of living cells without staining.

A type of microscopy that uses a beam of electrons to image specimens, providing much higher resolution than light microscopy.

An electron microscope that transmits a beam of electrons through a thin specimen, revealing internal structures and details.

An electron microscope that scans a focused beam of electrons across the surface of a specimen, creating a 3D image.

A nucleic acid that contains the genetic instructions for the development and functioning of all known living organisms. It consists of two long polymer strands of nucleotides linked by sugar-phosphate backbones, organized into chromosomes.

Structures found in the nucleus of cells that contain DNA organized into genes. They are duplicated during cell division and determine cell function, lifespan, and structure.

A micrograph (picture) of an individual's chromosomes arranged in pairs by size and shape, revealing the chromosomal composition.

A segment of DNA that provides instructions for making a specific protein, controlling cell activities and structures.
