What does a cell wall do?
The cell wall provides protection for the cell.
A consumer
Name one structure found in plant cells but not in animal cells.
One of the following: chloroplasts, vacuole or cell wall.
Why do we classify organisms?
To make it easier to talk to other scientists about organisms.
An organism that makes its own food is known as what?
A producer
What is the job of the vacuole?
To carry out tasks, such as photosynthesis that keep the plant alive
What is ecology?
Ecology is the study of the relationships between organisms.
What disease can be transmitted through sexual contact?
Gonorrhoea.
How did liquid water end up on Earth?
Water in the atmosphere fell as rain. This rain cooled the surface of the Earth over millions of years. Eventually, the Earth was cool enough for liquid water to exist.
Give three ways bacteria spread.
Any three of the following: Droplets, Air, direct contact, indirect contact, waterbourne, foodbourne, vectors.
How long ago did the Earth form?
4.54 Billion years ago.
What is climate?
Climate is the long-term weather conditions in a given area. Usually around 30 years
Put the following organisms into a food chain: caterpillar, sparrow hawk, wood pigeon, strawberry bush, red fox
Strawberry bush, caterpillar, wood pigeon, sparrow hawk, red fox
What is ecology?
Ecology is the study of the relationships between organisms.
What are three symptoms of a cholera infection?
Any three of the following: diarrhoea, vomiting, cramps, restlessness or thirst
Below is an example of a food chain.
grass, rabbit, fox. What would happen to the food chain if all the grass died?
If the grass died the rabbits would lose their source of food. The rabbit population would get smaller. The foxes would then have less rabbits to eat, so they start to die too.
What name do we give bacteria that cause disease?
Pathogens
How do we prevent cholera from spreading?
Isolating sick individuals, cleaning surfaces.
Does an organism need to be able to reproduce on its own to be living?
Yes
If a plant cell didn’t have a cell wall, what would happen to the cell?
The plant cell would lose the protection from having a cell wall. This would make it easier for bacteria to infect and other organisms to damage the cell.
When a virus is near to a cell it can infect it. This is an example of reacting to the environment. Why is a virus considered non-living?
Viruses are not made up of cells, and they can not reproduce on their own.
Explain what happens during the nutrient cycle.
Plants and animals die. The material is broken down by organisms in the ground known as decomposers. This releases nutrients back into the soil. The nutrients are taken up by new plants. The cycle repeats.
Michael has been ill for a number of days. He has a cough, a headache, and a fever. In what ways can Michael spread his illness?
Through droplets, and direct and indirect contact
Ms. Bell prepares a microscope slide. She places it under the microscope and focuses the lens.
Lindsay sees a cell that has a rigid wall. What type of cell is she looking at?
A plant cell.
Explain the water cycle.
Water evaporates into the air. Clouds of water form and move over land. As the temperature drops water falls to the Earth as rain. The rainwater flows into nearby water and the cycle repeats.
