Cells
Compared to a human, are cells big or small?
Small
Which is smaller: a tissue, an organ or an organ system?
A tissue
Where does the digestive system start?
The mouth and teeth
True or false: all animals see the same
False
The 4 topics in science we learn are:
Physics, Earth, Biology, and Chemistry
List one part of cell theory
- All organisms are made of cells
- All cells come from other cells
Define and organ. Include the word tissue
An organ is a multicellular organism which has its own specific function/job. Organs are made up of many cells joining together to make different tissues.
What is the main function/job of the digestive system?
To break down food we eat into useful energy and nutrients for our body.
Someone who has trouble seeing certain colours in images might have what condition?
Colourblindness.
Next term our topic is?
Chemistry
What is one main organelle difference between plant and animal cells?
- Plant cells have a cell wall
- Plant cells have chloroplasts
What is the main organ that is apart of the cardiovascular system?
The Heart
Why is the digestive system connected to the circulatory system?
So the blood can move through the broken down food nutrients and energy to where it needs to be.
The name and function of the part of the eye being shown in the diagram is:
Pupil - controls the amount of light that enters the eye.
What are the 3 states of matter?
Solid, liquid, gas
What was the name of the scientist who names the cell?
Robert Hooke
What are the 4 main types of tissue in the human body?
a) Bone, cardiovascular, connective, and squamons
b) Bacterial, eukaryote, prokaryote, and viral
c) Connective, epithelial, muscle, and nervous
d) Circulatory, digestive, epithelial, and immune
C
The digestive system involves both chemical and physical breakdown of food. Identify and example of where each of these happen.
Physical - teeth, mouth, stomach, small intestine
Chemical - salivary, glands, stomach, intestines, liver, pancreas, gall bladder.
What is the function of the eye lens?
What is one difference between a plant and animal cell?
Plant cells have chloroplast, but animal cells don't.
Name a type of human cell, and an organ system where you might find it
Neuron/Nerve Cell - Nervous System
Muscle Cell - Muscular System
Sperm Cell - Reproductive System
White blood cell - Immune System
Explain how the lungs do their job?
Lungs bring in oxygen and take out CO2.
Oxygen and C02 both travel in our blood, and can move through the small blood vessels into/out of the alveoli.
Which organ in the digestive system has the main job of removing excess moisture and forming the stool?
Large Intestine
When you shine a light into a humans eye you see a red shine, while other animals have different coloured eye shine. What part of the eye is responsible for this?
In term 1, we learnt about physics, what is the difference between an energy transfer, and energy transformation?
Transfer means energy moves from one spot to another. Transformation is when energy changes from one type to another.
