Bacteria and viruses
100

This organelle is responsible for converting sunlight into energy for plant cells.

Chloroplast

100

This type of organism, which includes bacteria, viruses, and fungi, can cause disease in a host.

Pathogen

100

This form of reproduction involves a single parent organism producing offspring that are genetically identical.

Asexual reproduction

100

This term refers to all the living organisms on Earth, along with their environment.

Biosphere

100

These are viruses that solely kill and selectively target bacteria

Bacteriophages

200

This structure surrounds the cell and regulates what enters and exits

Cell membrane

200

This type of microorganism can only reproduce inside a host cell and may cause illnesses like the flu.

Virus

200

This is the type of cell produced during sexual reproduction, such as sperm or egg.

Gamete

200

These small organisms are at the base of aquatic food chains and can be either plant-like or animal-like.

Zooplankton

200

This structure is found in viruses and is made up of proteins that protect the genetic material.

Capsid

300

This jelly-like substance inside cells is where organelles are suspended

Cytoplasm

300

These ancient bacteria thrive in extreme environments, such as hot springs or salt flats

Archaebacteria

300

This organism reproduces by budding, where a new organism grows from the parent.

Yeast

300

This is the term for the relationship between two different species living together

Symbiosis
300

This is the viral reproductive cycle in which the virus integrates its DNA into the host genome and remains dormant.

Lysogenic cycle

400

These are tiny structures within a cell that perform specific functions, such as protein synthesis

Organelles

400

This tough, dormant structure allows bacteria to survive extreme conditions like heat, radiation, and dryness.

Endospores

400

The offspring formed by sexual reproduction begins as this fertilized cell.

Zygote

400

This is a process where an organism responds to changes in its environment.

Stimulus

400

This type of bacteria has a spherical shape.

Coccus

500

This organelle is the site of ribosome production within the cell.

Nucleolus

500

This is the term for the process in which a virus enters and kills a host cell.

Lysis

500

This taxonomic rank is used to categorize organisms into groups based on shared characteristics.

Genus

500

This theory suggests that life on Earth may have originated from a mixture of organic compounds in the early oceans.

Primordial soup

500

This type of bacteria is characterized by a curved, comma-like shape and is often found in aquatic environments.
