living things and cells

science

characteristics of life

cells, nutrition, excretion, response and reproduction

cells

the basic building blocks of all living things

nutrition

the way in which living things get thier food

excretion

the way in which living things get rid of the waste that they produce

response

the way in which living things react to change in their enviroment

reproduction

the way in which living things create new living things

organism

a living thing that has the characteristics of life

kingdoms of life

animal, plant, fungi, bacteria, protista

bacteria

the simplest forms of life

fungi

simple forms of life that can cause disease but can also be very beneficial. Yeast can be used to produce alcohol

plants

complex forms of life, plants are capable of producing their own food for example shrubs bushes trees

animal

complex forms of life. must eat other organisms to obtain their food, for example rabbit or wolf

protista

seaweed and ameobas. can be unicellular or multicellular but are simple and hard to define

bacteria

the simplest forms of life and are very small. can be dangerous and disease causing

vertibrates

animals that have a backbone e.g. cat, dog, horse

invertebrate

animals with no backbone e.g. jellyfish, bees, spiders

cells

all living things are made out of cells

nuclues

controls the cell and all of its activities. also contains chromosomes that hold our genetic code

cytoplasm

the jelly like substance found in the cells and where the chemical reactions take place

cell membrane

surrounds the cell and holds keeps cell content inside. also controls what enters and exits the cell

ribosome

small structures used to make protiens

mitochondrion

provides energy to the cell

cell wall

provides structure and support to the cell

vacuole

stores water food and waste in the cell

chloroplast

allows the plant to make its own food. contains the green pigment chlorophyll
