Living organisms need this to provide them with energy and the raw materials for growth and repair
Nutrition
1 of 23
Organisms releasing food
Respiration
2 of 23
Waste products such as carbon dioxide and urine leaving an organism
Excretion
3 of 23
Reacting to changes in environment
Sensitivity
4 of 23
Going towards and away from water, food, predators and poisons
Movement
5 of 23
Being able to regulate internal conditions including temperature and water content
Control
6 of 23
Multiplying
Reproduce
7 of 23
Tiny structures within cells (nucleus, cyptoplasm)
Organelles
8 of 23
Groups of organelles which work together to carry out a particular function
Specialised cells
9 of 23
A group of similar cells which work together to carry out a particular function
Tissues
10 of 23
A group of different tissues that work together to carry out a particular function
Organs
11 of 23
Groups of organs
Organ systems
12 of 23
Multicellular, contain chloroplasts, can photosynthesise, have cell walls made of cellulose and store carbohydrates as starch
Plants
13 of 23
Multicellular, can't photosynthesise, no cell walls, most have nervous coordination, can move around and store carbohydrates as glycogen
Animals
14 of 23
Some are single-celled, others have a body called a mycelium which is made of hyphae (which contain many nuclei), have cell walls made of chitin, feed by saprotophic nutrition and they store carbohydrates as glycogen
Fungi
15 of 23
Single-celled, some have chloroplasts but others are like animal cells
Protoctists
16 of 23
Single-celled, no nucleus, they contain a circular chromosome of DNA nad they feed of other organisms
Bacteria
17 of 23
Particles not cells, can only reproduce inside living cells so they are parasites, infect all types of living organsims, different shapes and sizes but they dint have a cellular structure, they have a protein coat around some genetic material.
Viruses
18 of 23
Organisms which cause disease
Pathogens
19 of 23
A substance which increases the speed of a reaction without being changed or used up in the reaction
Catalysts
20 of 23
The net movement of particles from an area of higher concentration to an area of lower concentration
Diffusion
21 of 23
The net movement of water molecules across a partially permeable membrane from a region of higher water concentration to a region of lower water concentration
Osmosis
22 of 23
The movement of particles against a concentration gradient (i.ei from an are of lower concentration to an area of higher concentration) using energy released during respiration
Active Transport
