what is the word equation for photosynthesis
carbon dioxide+water=oxygen+glucose
1 of 38
what is the symbol equation for photosynthesis
6CO₂+6H₂O→C₆H₁₂O₆+6O₂
2 of 38
What do plant cells have that animal cells dont
Cell wall, Chloroplasts, Permanent vacuole
3 of 38
what carries out aerobic respiration in the cell
mitochondria
4 of 38
where does protein synthesis happen
ribosome
5 of 38
list the uses of theses organelles: nucleus, cytoplasm, cell membrane
nucleus: contains genetic material, which controls the cell activities/cytoplasm: most chemical processes occur here, controlled by enzymes/Cell membrane: controls the movement of substances in and out of the cell
6 of 38
list the uses of these organelles:mitochondria,ribosome
Mitochondria: most energy is released here via aerobic respiration, ribosomes: is where protein synthesis happens
7 of 38
list the uses of these organelles found only in plants: cell wall, Chloroplasts, permanent vacuole
Cell wall: keeps the structure, Chloroplasts: contains chlorophyll that absorbs light energy for photosynthesis,Permanent vacuole: filled with cell sap to keep turgid structure

how does a fungus digest their food
They use saprotrophic nutrition. They secrete enzymes onto their food so that digestion happens outside the fungal cells
9 of 38
name an example of a multicellular fungus
mucor are organised into a mycelium which is made from thread-like structures called HYPAE
10 of 38
what are the key points of bacteria
release poisonous toxins that make humans feel ill/ they are a pathogen/ single celled and cause cholera and typhoid
11 of 38
what is a pathogen
they are a microorganism such as bacteria and viruses that cause disease
12 of 38
What do all living organisms do
Movement ReproductionSensitivityGrowthRespirationExcretionNutrition
13 of 38
how are viruses deadly
they will reproduce inside a host cell until the cell burst and they get ing the bloodstream
14 of 38
what disease are caused by viruses and how is their genetic material stored
viruses consist of a fragment of genetic material inside a protective protein coatDiseases consist of influenza,colds and measles
15 of 38
what is a proctoctista
they are also pathogens,unicellular e.g. an animal like one is an amoeba and a plant like one is a chlorella that will photosynthesis

label the structure of this influenza
pic of round influenza
17 of 38
label the standard virus
pic of standard virus
18 of 38
what is an organelle
a cell structure that is specialized to carry out a particular job or function
19 of 38
what is a cell
basic structural and functional unit of a living organism
20 of 38
what is a tissue
A group of cells with similar structures, working together to perform a shared function
21 of 38
what is an organ
A structure made up of a group of tissues, working together to perform specific functions
22 of 38
what is an organ system
A group of organs whith related functions, working together to perform body functions
23 of 38
what is diffusion
diffusion is the NET MOVEMENT of the particles of a substance from a region of high concentration to an area of low concentration
24 of 38
what will increase the rate of diffusion
A greater surface area of the cell membrane/A greater difference between concentrations inside and outside he cell/the distance the particles have to travel is short and the temperature is increased- this makes the diffusing particles move faster
25 of 38
What elements are in these biological molecules/carbohydrates, proteins, lipids( fat and oils)
carbohydrate: Carbon C Hydrogen H Oxygen O Lipid: Carbon C Hydrogen H Oxygen O/protein: Carbon C Hydrogen H Oxygen O Nitrogen N
26 of 38
what is osmosis
Osmosis is the diffusion of water from a high concentration to a low concentration of water( concentrated solution through a partially permeable membrane
27 of 38
What is active transport
the movement of particles from an area of low concentration to an are of high concentration ( against the concentration gradient) for example root hairs and this requires energy from respiration
28 of 38
what do carbohydrates take the structure of
Polymers( complex sugars) e.g. pasta Monomers(simple sugars (chocolate)
29 of 38
what are proteins
Proteins are polymers made by joining amino acids
30 of 38
what are lipids
lipids are fats and oils they are large molecule made from smaller units of fatty acid and glycerol
31 of 38
what results would be expected
!st =degrees 2nd=volume of O₂ collected/ 10=65/20= 70/30=72/40=80/50=60/60=18
32 of 38
Explain the results from the data collected from the experiment
as the temperature increased there was more kinetic energy so there was more successful collisions but as the temp went over 37 the body temp they became denatured and failed to function so more became redundant. less had kinetic energy at the start
33 of 38
what is the test for glucose
BENEDICTS SOLUTION: goes blue if non present/ goes green if traces of reducing sugar/orange if moderate amount/brick red if high amount
34 of 38
what is the test for starch
Add iodine solution and if turns YELLOW BROWN to BLUE BLACK then starch is present
35 of 38
what is the link between varying levels of CO₂ concentration and varying light intensity and varying temperature in the rate of photosynthesis
if one aspect is low then the plant can only use a low amount of the other two aspects
36 of 38
label this picture of the leaf
pic of leaf with full set
37 of 38
how has the leaf adapted for photosynthesis
it has a larger surface area for absorption of light, there is a short distance for the carbon dioxide to diffuse,absorbs sunlight to transfer into chemicals
