Year 8 Revision

What is classification?

• Living organisms are classified into groups depending on their characteristics.

• Classification is the process of naming only plants.

• Classification is the study of chemical reactions.

• Classification is the grouping of non-living things only.

What are the 5 kingdoms of living things?

• Animals, Plants, Protists, Prokaryotes, Fungi

• Animals, Plants, Bacteria, Viruses, Fungi

• Animals, Plants, Algae, Bacteria, Fungi

• Animals, Plants, Insects, Bacteria, Fungi

What is the function of the nucleus in animal and plant cells?

• Contains the genetic material (DNA) of the cell. Controls the cell activities.

• Produces energy for the cell.

• Regulates the movement of substances in and out of the cell.

• Stores water, nutrients, and waste products.

What is the function of the cell membrane in animal and plant cells?

• Controls the entry and exit of substances into and out of the cell.

• Produces energy for the cell.

• Stores genetic information.

• Synthesizes proteins.

What is the function of the cytoplasm in animal and plant cells?

• Location of many chemical reactions.

• Controls the entry and exit of substances.

• Stores genetic information.

• Produces energy for the cell.

What is the function of mitochondria in animal and plant cells?

• Site of aerobic respiration.

• Storage of genetic material.

• Synthesis of proteins.

• Control of cell division.

What is the function of ribosomes in animal and plant cells?

• Site of protein synthesis (where proteins are made).

• Storage of genetic information.

• Production of energy through photosynthesis.

• Regulation of cell division.

What is the function of chloroplasts in plant cells?

• Site of photosynthesis.

• Storage of genetic material.

• Protein synthesis.

• Regulation of cell division.

What is the function of the vacuole in plant cells?

• Water storage and maintenance of cell shape.

• Photosynthesis and energy production.

• Protein synthesis and transport.

• DNA replication and repair.

What is the function of the cell wall in plant cells?

• Provides structure and support.

• Controls the movement of substances in and out of the cell.

• Produces energy for the cell.

• Stores genetic information.
