What are systems made up of? Give 3 examples.
Organs working together to perform a similar function. Examples include the circulatory system, the digestive system and the nervous system.
Give 2 examples of organisms which belong to the protist kingdom.
Algae, amoeba.
Give 5 examples of specialised cells.
Red blood cells, white blood cells, nerve cells, root hair cells, leaf cells.
How to plants take in nutrients from their environment?
They produce their own food through photosynthesis.
What do decomposers feed on? Give two examples of decomposers.
Fungi and bacteria feed on the remains of dead plants and animals.
What are the 5 kinddoms that all living things are classified into?
Monera, Protist, Fungus, Plant, Animal.
What do cell walls do?
Protect the cell.
How to animals take in nutrients from their environment?
Feeding on other living things.
What do white blood cells do?
Protect the body from bacteria, viruses and other foreign invaders.
What is cytoplasm?
A jelly-like substance that fills the cell where chemical reactions happen.
What does the nucleus of a cell do?
It controls the functions of the cell such as reproduction.
What are the 2 main types of reproduction and how are they different?
Asexual reproduction occurs when only one organism is required. Sexual reproduction involves two animals of the same species; a male and a female.
What do nerve cells do?
Carry information from the brain to other parts of the body.
What 2 things do plant cells have which animal cells don't?
Cell walls and chloroplasts.
What do red blood cells do? Why are they red?
Carry oxyen around the body. They are red because they contain hemoglobin, a bright red protein that contains iron.
What does the cell membrane do?
It controls the substances that enter and leave the cell.
What do vacuoles do?
Contain water and minerals which the organism needs in order to grow.
What are tissues made up of? Give 2 examples of tissues.
Cells with similar stuctures and functions. Examples include muscle tissue and xylem.
What do chloroplasts do?
Contain cholophyll which is needed for photosynthesis.
During photosynthesis what gases are absorbed and released by plants?
Oxygen is released and carbon dioxide is absorbed.
What are the 3 life processes which all living things perform?
Nutrition, reproduction and interaction.
What do leaf cells do?
Absorb sunlight so photosynthesis can take place.
What do root hair cells do?
Absorb water and minerals from the soil.
What do organs do? Give 2 examples of animal organs and 2 examples of plant organs.
Organs work together to carry out a particular function. Examples: heart, lungs, stomach, brain (animal) roots, leaves (plant).
What is interaction?
When living things react to changes in their environment (stimuli).
