Grade 10 Biology Quiz (pg. 1-9)

What are cells?

Cells are the smallest and most basic unit of life that can support all characteristics of living things.

What are all living things made up of?

All living things are made up of one or more cells.

Where do all cells come from?

All cells come from other cells.

Recall the cell theory.

1. All living things are made up of one or more cells

2. The cell is the basic unit of life

3. All cells come from other cells

What is a eukaryote?

A eukaryote are organisms that cells have a nucleus. It can be single celled organisms, or multicellular organisms.

What is a prokaryote?

A prokaryote are single celled organisms that do not have a nucleus. They consist of bacteria and archaea.

What are microorganisms?

Micro organisms are any living thing that is too small to see with the naked eye.

Where can microorganisms be found?

Microorganisms can be found in the air, in the water, and on plants and animals.

List the four main types of microorganisms.

1. Monera (bacteria)

2. Protists ( found in water)

3. Fungi (mould)

4. Viruses

What are the characteristics of living bacteria?

• Asexual Reproduction

• Large (use light microscope)

• Cell wall

• Single-celled

• Single chromosome

• Harmful & beneficial

• Localized infections (food poisoning, pneumonia)

• Treated with antibiotics

What are the characteristics of non-living viruses?

• Needs a host to replicate DNA

• Small (use electron microscope)

• Protein coat

• Non-cellular

• DNA/RNA strand

• Harmful

• Systematic infections (AIDS, flu, COVID-19)

• Treated with vaccines.

What characteristics do bacteria and viruses share?

• Microscopic

• Causes infections

7 characteristics of all living things.

1. Have a lifespan

2. Grows (in size, reproduces, and repairs itself)

3. Consents and respond to changes in their environment/stimuli (able to move)

4. Requires energy (nutrition/photosynthesis)

5. Produces waste

6. Made up of cells

7. Respiration (exchange gases with environment)

For the cells structure, what is made up of?

Cells are made up of organelles.

What are organelles?

Organelles are cell structure that perform specific functions for the cell.

Describe the shape of a animal cell, and a plant cell.

Animal: round and spherical

Plant: rigid and rectangular

Describe the cell membrane.
