WHAT ARE THE 7 PROPERTIES OF LIFE?
- ORGANIZATION
- SENSITIVITY/RESPONSE TO STIMULI
- REPRODUCTION
- GROWTH AND DEVELOPMENT
- HOMEOSTASIS
- ENERGY PROCESSING
- ADAPTATION
helps living organisms adjust and continue the cycle of life
PROPERTIES OF LIFE
Living things are highly organized, meaning they contain specialized, coordinated parts. Living organisms are made up of one or more cells, which are considered the fundamental units of life.
ORGANIZATION
Living organisms show “irritability”, meaning they respond to stimuli or changes in environment
SENSITIVITY/RESPONSE TO STIMULI
Living organisms can reproduce themselves to create new organisms. When ____ occurs, genes containing DNA are passed along to an organism’s offspring. These genes ensure that the offspring will belong to the same species and will have similar characteristics, like size and shape
REPRODUCTION
2 TYPES OF REPRODUCTION
ASEXUAL & SEXUAL REPRODUCTION
Organisms grow/develop following specific instructions coded by their genes. Genes provide instructions that will direct cellular growth/development, ensuring that a species young will grow to exhibit many same characteristics as its parents.
GROWTH AND DEVELOPMENT
Living organisms regulate their internal environment to maintain the narrow range of conditions needed for cell function. The maintenance of a stable environment, even in the changing external environment
HOMEOSTASIS
Your body temp needs to be kept relatively close to ____
98.6F (37C)
All organisms use a source of energy for their metabolic activities
ENERGY PROCESSING
TYPE OF ENERGY PROCESSING WHERE: organisms capture energy from the sun and convert it into food.
PHOTOSYNTHESIS
TYPE OF ENERGY PROCESSING WHERE: process when organisms combine oxygen with food stuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding as waste products, carbon dioxide, and water
CELLULAR RESPIRATION
A heritable trait that provides a fitness advantage that may become more common in population, making it better suited to its environment
ADAPTATION
Does not need two parents to produce an offspring. Ensures that the offspring carries the same genetic information as their parent
ASEXUAL REPRODUCTION
3 TYPES OF ASEXUAL REPRODUCTION IN ANIMALS
- FISSION
- FRAGMENTATION
- BUDDING
TYPE OF ASEXUAL REPRODUCTION: where two individuals will form as the parents and divide in half
FISSION
2 TYPES OF FISSION
BINARY & MULTIPLE
TYPE OF FISSION? involves two individuals formed from a single parent
BINARY FISSION
TYPE OF FISSION? result in several off-springs that formed from a single parent
MULTIPLE FISSION
TYPE OF ASEXUAL REPRODUCTION: involves the breaking of body parts into fragments, followed by regeneration, and regrowth of lost parts
FRAGMENTATION
TYPE OF ASEXUAL REPRODUCTION: happens when an outgrowth, called a bud, grows and develops from the parent animal. The bud separates to become a new individual or remain attach in the form of a colony
BUDDING
Needs two parents to produce an offspring. Involves male and female parents to produce offspring through the fusion of gametes (sperm & egg cells)
SEXUAL REPRODUCTION
the fusion of gametes (sperm & egg cells) generated by
MEIOSIS
THIS increases THE chances of species variation
The combination of genes from both parents
union of gametes that lead to the development of a new individual.
FERTILIZATION
2 TYPES OF FERTILIZATION
EXTERNAL & INTERNAL
TYPE OF FERTILIZATION? union of egg and sperm occurs outside the female reproductive tract. Common among aquatic animals, especially in most bony fish and amphibians
EXTERNAL FERTILIZATION
TYPE OF FERTILIZATION? union of egg and sperm occurs within the female reproductive tract. The male parent releases the sperm cells into the reproductive tract of the female parent
INTERNAL FERTILIZATION
3 WAYS ANIMALS PRODUCE OFFSPRINGS IN INTERNAL FERTILIZATION:
- OVIPARITY
- OVOVIVIPARITY
- VIVIPARITY
WAY OF INTERNAL FERTILIZATION? eggs are fertilized internally, but development completes outside the mother’s body
OVIPARITY
WAY OF INTERNAL FERTILIZATION? embryos develop inside eggs that are retained within the mother’s body until they’re ready to hatch
OVOVIVIPARITY
WAY OF INTERNAL FERTILIZATION? eggs are fertilized internally. Embryos receive nourishment directly from the mother’s blood through the placenta
VIVIPARITY
