The Organism

Front 1

matter

Back 1

invisible particles called atoms

Front 2

atoms

Back 2

made of four elements-
carbon
hydrogen
oxygen
nitrogen

Front 3

molecule

Back 3

two or more atoms join to form a molecule

Front 4

chemical reactions are

Back 4

the basis for all body processes

Front 5

three main types of chemical reactions and give a description of each

Back 5

1. synthesis- A+B=AB
2. decomposition- AB=A+B
3. metabolism- a biochemical modification of chemical compounds of living organisms and cells

Front 6

cellular level

Back 6

cells are the smallest living units of an organism

Front 7

anatomy of a cell, three parts

Back 7

1.cellular membrane-lypids and proteins
2. cytoplasm-intracellular fluid which gives cells substance and suspends organelles
3. nucleus- large organelle containing DNA

Front 8

simple diffusion

Back 8

passive transport
substances move from an area of high concentration to an area of low concentration, this happens chemically through the cell membrane

Front 9

active transport

Back 9

temporary attachments are formed between molecules and protein, the molecule can then take the protein through the cell membrane

Front 10

phagocytosis

Back 10

a cell absorbs large particles through the cell membrane (a vesicle surrounds the particle and envelopes the particle)the cell then spits out what it doesn't want

Front 11

pinocytosis

Back 11

same a phagocytosis but with small particles

Front 12

exocytosis

Back 12

expulsion of waste from the cell

Front 13

cellular reprodution

Back 13

mitosis- when every aspect of the cell is reproduced
one parent cell divides into two daughter cells that are fully functioning
