1	How do particles move in and out of cells?	By diffusion.
2	How does the amoeba eat?	It eats bacteria, algae, and plant cells by engulfing and they reproduce by splitting in half binary fission.
3	How does the Amoeba move?	They move by moving part of follow slowly in the same direction.
4	What are organisms?	Organisms are living things made up of cells. Some are only made up of one cell.
5	What are special features in the red blood cell?	No nucleus and it is disc shaped to create surface area.
6	What are the components in the Euglena?	Nucleus, vacuole, chloroplast, Eye spot, contractor and flagellum.
7	What are the components of a microscope?	Eye piece ,nose piece, objective lens, condenser lens, fine focusing knob, course focusing knob, diaphragms lamp and stage.
8	What are the components of a plant cell?	A cell membrane, cytoplasm, mitochondria, nucleus, vacuole, cell wall and chloroplast.
9	What are the components of an animal cell?	A cell membrane mitochondria, nucleus, and cytoplasm.
10	What are the components of the Amoeba?	Cell membrane, nucleus, food vacuole, contractor, pseudopod. ( vacuole removes waist)
11	What are unicellular organisms?	They only consist of one cell they have no fixed shape and adapted to carry out many different functions.
12	What do leaf cells carry out?	They carry out photosynthesis.
13	What do root hair cells create?	They create large surf services and they have no chloroplasts as they are underground.
14	What do sperm cells carry?	Male genetic material.
15	What do sperm cells look like?	They have a streamlined head and a long tail.
16	What does a nerve cell look like?	It is long and thin with connections are each end.
17	What does a red blood cell contain?	Haemoglobin which joins to oxygen.
18	What does the chloroplasts do for the Euglena?	It makes their own food by photosynthesis.
19	What does the eye spot do for the Euglena?	It dictates light.
20	What does the flagellum allow the Euglena to do?	It allows the Euglena to move towards the light to make more food.
21	What does the nucleus control in the Amoeba?	Growth and reproduction.
22	What does the specimen need to be?	Needs to be thin so I can pass through a dye can be added to make it easier to see.
23	What happens during diffusion?	Particles spread from high concentration to low concentration, glucose and oxygen move from the blood into cells by diffusion, dioxide moves out of cells to the blood by diffusion.
24	What is a red blood cell’s job?	To transport oxygen around the body.
25	What is a root hair cell?	It’s a plant cell that absorbs water and nutrients from soil.
26	What is a specialised cell?	A cell that has special features that allow them to do a specific job or function.
27	What is step 1 to using a microscope?	Move the stage to its lowest position and place a slide on it.
28	What is step 2 to using a microscope?	Choose the objective lens with the lowest magnification.
29	What is step 3 to using a microscope?	Look through the eyepiece and turn knob till you see the object.
30	What is step 4 to using a microscope?	Turn the fine focus knob until it comes into focus.
31	What is step 5 to using a microscope?	Repeat the steps using a higher magnification lense.
32	What is the Euglena?	The Euglena is a microscopic organism found in freshwater.
33	What is the fifth level of organisation?	A multicellular organism a group of systems working together made up of many cells and five stages.
34	What is the first level of organisation?	The cell is the smallest building block of an organism.
35	What is the fourth level of organisation?	Organ system, a group of organs working together.
36	What is the job of a nerve cell (neurone)?	To carry electrical impulses around the body.
37	What is the second level of organisation?	Tissue a group of specialised cells working together.
38	What is the third level of organisation?	Organ a group of tissues working together.
39	Where are leaf cells found?	They are found at the top of the surfaces of leaves packed with chloroplasts.
40	Why do sperm cells have lots of mitochondria?	So they are able to transfer energy.
