What is Sustainability
The ability of the environment and the living things it supports to endure into the future.
What is Reproductions role in sustainability
Reproduction ensures that organisms have a source of nutrients and energy to sustain their life processes.
what does continuity mean
how each species of organism continues to exist over time from one generation to another
what is the importance of reproduction
ensures that life exists beyond its present generation. All life depends on the ability of cells to reproduce
what are the two ways in which living things can reproduce
sexual and asexual
what is asexual reproduction?
offspring come from a single parent. Each offspring recieves a copy of the parent’s genetic material. As a result offspring are genetically identical to the parent and to each other.
what is sexual reproduction?
two parents each contribute half of the offspring’s genetic material. As a result, the offspring have genetic information that is different from either parent’s so the offspring are not identical to their parents or in most cases each other.
What is the same between asexual and sexual reproduction?
the genetic material and the information it holds is passed on to the offspring
Where is the genetic information from the parents contained?
The DNA
What are the building blocks of DNA
Nucleotides
what is a DNA sequence
the specific Order in which the nucleotides are linked together
What is the function of DNA
holds the genetic information that is passed on to offspring
how is sexual reproduction different from asexual reproduction
asexual comes from one parent contributing all the parents genetic material and offspring are identical to the parents and to each other.
sexual comes from two parents contributing half of the offspring’s genetic material therefore different from the parents and, in most cases, its siblings.
what is binary fission
a type of asexual reproduction in which a cell splits into two daughter cells that have identical genetic information
what is a spore?
a structure that produces a new organism by asexual reproduction
Explain the cell cycle? and what are the two main stages?
a series of events in the life cycle of a cell. It consists of two main stages: 1) Growth and Development and 2) Cell Division
what is vegetative propagation?
asexual reproduction of a plant from part of its roots, stems, or leaves
What is budding?
a type of asexual reproduction that involves the formation of an outgrowth, or bud, from a parent cell
What is a clone?
An exact copy of a cell or organism
How is food poisoning an example of reproduction?
Food poisoning is a result of microbes (example bacteria such as salmonella and E coli) that can reproduce at very fast rates in a short period of time (populations can double in minutes) becoming a threat to our health.
what is an eukaryote?
an organism composed of one or more cells that consist of a nucleus and other internal structures that are surrounded by membranes.
what are the two ways plant cells can reproduce
asexually and sexually
how does a plant cell reproduce sexually
what is asexual reproduction in plants called
Vegetative propogation. new plants grow from a portion of the roots stems or leaves of an existing plant becoming clones of the original plant.
