Studied by 1 personunicellular organisms
Organisms consisting of a single cell.
excretion
Removal of waste products by an organism.
waste
All living organisms produce ________ that needs to be removed.
Sperm
________ and egg cells fuse to form a child with combined genetic set.
eg plants
Can be obtained by eating other organisms or from the environment (________ photosynthesise)
Catabolism Organisms
________ break down complex molecules into simple molecules- releases energy.
Cells
The smallest structural and functional units of all organisms, and are usually only visible through microscopes.
Survival of organisms
________ requires food for energy and nutrients.
genetic information
Parents produce sperm and egg cells, each with half the ________ that the child will receive.
total of all biochemical reactions
The ________ occurring in a living organism is called metabolism.
Cells
________ differentiate and have different purposes early on (skin, muscle, blood, nerve ________ etc)
cell
The ________ is the smallest unit of life.
Anabolism; Organisms form complex molecules from simple molecules
consumes energy
Catabolism; Organisms break down complex molecules into simple molecules
releases energy
Sexual
two parents
Associated with mitosis
cell division
Anabolism
Organisms form complex molecules from simple molecules - consumes energy.
Catabolism
Organisms break down complex molecules into simple molecules - releases energy.
Asexual reproduction
Offspring is produced by a single parent which inherits all the parent's genes.
Sexual reproduction
Offspring is produced by the combination of sperm and egg cells from two parents
Homeostasis
Regulation of internal environment to a stable level.
Growth
An organism's development over time.
Excretion
Removal of waste products from an organism.
Unicellular organism
Composed of one cell which performs all functions required for life.
Multicellular organism
Composed of more than one cell which together perform all functions required for life.
