Resource summary

Life Processes and Cells
1 Life Processes
1.1.1 Movement The ability to move parts of the body
1.1.2 Respiration Release of energy from food
1.1.3 Sensitivity The ability to respond to changes in the surroundings
1.1.4 Growth To grow to adult size
1.1.5 Excretion To release waste products
1.1.6 Nutrition To obtain food (plants- photosynthesis)
1.1.7 Reproduction To produce offspring (flowers germinate)
2 Specialized Cells
2.1 Plant Cells
2.1.1 Root Hair cell Function To absorb water and minerals from the soil Adaptation Has long and thin hair
2.1.2 Paliside cells Function To absorb light for photosynthesis Adaptaion They have a lot of chloroplasts
2.2 Animal Cells
2.2.1 Ciliated Epithelial Cell Function Keeps the trachea (windpipe) clear of thengs like dust Adaptation Has tiny cilia, hair which brush away dirt
2.2.2 Nerve Cells (Neurons) Function They conduct messages around the body Adaptation Are shaped like wires The information goes past quicker
2.2.3 Red Blood Cell Function Carries oxygen around the body Adaptation They have no nucleus They have a large surface area More area to absorb and to release oxygen
2.2.4 White Blood Cell Function To protect the body and engulf and destroy bacteria and other harmful microbes Adaption Their cytoplasm can flow so they move around mor easily
3 Plant and animal cells
3.1 Animal cells
3.1.1 The Nucleus Controls all activities in the cell
3.1.2 The Cell membrane Controls what leaves and enters the cell Keeps the cell together
3.1.3 The Cytoplasm Jelly like Chemical reactions happen here
3.2 Plant cells
3.2.1 The Nucleus Controls all activities in the cell
3.2.2 The Cytoplasm Chemical reactions happen here
3.2.3 The Cell Membrane Controls what leaves and enters the cell Keeps the cell together
3.2.4 The Vacuole A large place containing cell sap
3.2.5 Chloroplasts The structures where photosynthesis happens They contain chlorophyll
3.2.6 The Cell Wall Made of cellulose Gives a plant cell strength and support
4 Tissues and organs
4.1 Organs
4.1.1 Organs are made up of different tissues working together
4.1.2 Examples Liver Kidneys Stomach Intestines Brain Heart The Heart is made up of Muscle tissue Nervous tissue Cartilage Fat Tissue Blood Skin The skin is the largest organ!
4.1.3 A group of organs working together is called an organ system cardovascular The digestive system The nervous system The muscle system
4.2 Tissues
4.2.1 Tissues are a group of similar cells that are working together
