A membrane-bound compartment that holds the genetic material or DNA in cells.

Cells that do not have a nucleus. Example: Bacteria

The internal environment of the cell including water, dissolved substances and sometimes organelles.

Consisting of a single cell. Ex: Protozoa, bacteria, some algae.

Consisting of many cells. Plants, fungi, and animals may contain hundreds to billions of cells.

The material that surrounds all cells. It works as a filter to regulate the movement of substances in and out of a cell.

This material regulates all cell functions and is sometimes free floating in the cytoplasm and in some cells it is in the nucleus.

Parts that help cells move around: cilia and flagella (thin filaments)

Compartments inside the cytoplasm: ribosomes, vacuoles, mitochondria, etc.

A membrane-bound compartment that holds the genetic material or DNA in cells.

Cells that have a nucleus. Examples: Plant and animal cells

Cells that do not have a nucleus. Examples: Paramecium and Amoeba

The largest & most diverse group of prokaryotic organisms. They can be spherical, rod, corkscrew, or bean shaped.

A form of life that has processes that carry out living functions. Single or multi-cell.

Living things - people, plants, bacteria

Normal action of something or what something does. Eating, sleeping, moving...

Non-living things - rock, metal, air, water...

A lens that enlarges the image of an object.

An instrument that uses visible light, a lens and objective to magnify objects - cells, crystals

The size of a multicellular organism is not related to the size of its cells. The cells of an ant, a mouse, and an elephant are similar in size

A pitbull has more cells than these three organisms. (check 3 choices)

When an organism is growing, the number of cells it has increases, but not their size.

An organelle that is the powerhouse of the cell

An organelle that converts sunlight to energy

An organelle that contains the genetic material of the cell

This provides structure and support for plant cells

The students learn that eukaryotic cells have a nucleus and prokaryotic cells do not have a nucleus. They observe the samples and record their observations in this chart.

The students claim that all living things have a nucleus. Is the students' claim true or false

The students examine a sample that contains moving objects that each have a nucleus. The image shows the sample under the microscope.

Which statement correctly describes the sample?
