Life Science
Explain that cells are the basic unit of structures and function
of living organisms.


Cells are the basic unit of structures of living
organisms because it is the smallest unit of life that
is classified as a living thing, and is often called the
building block of life.
Cells are the basic unit of function of living
organisms because all cells are made by other cells.
Basic units of life

The basic units of life is made up of more or one
cells.

Cells are the basic unit of all living things.

Those cells are produced by other cells.
Cells have different jobs



Cells that have the same job combine together to form
body tissue. (muscles, skin, or bone tissue)
Groups of other cells make up the organs in our body's.
(heart, liver, or lungs)
Those organs have there own jobs, but all organs work
together. They make up the systems in your body.
Those systems keep you alive and healthy.
Animal Cell
Eukaryotic Cell

Has cell membrane
Allows
material to enter and
leave the cell.





Nucleus-contains DNA
Mitochondria-energy is
stored and used,
contains DNA
ER- transportation
system within the cell
Ribosomes- protein is
made
Vacuoles- closets, store
stuff
Plant Cell

Cell Wall
Function is protection,
support, structure.

Chloroplasts

Contain chlorophyll


Make the plant
green
Function is to
produce food
Explain the characteristics of life as indicated by
cellular processes.

The characteristics of life as indicated by cellular
processes is movement, sensitivity, growth,
excretion, reproduction.
Describe the process of cell division and development.
.

The process of cell division and development
is to growth of the cell population, where one
cell grows and divides to produce two
“daughter cells”.
Mitosis is...

Is the process by which a eukaryotic cell
separates the chromosomes in its cell nucleus
into two identical sets in two nuclei.
Meiosis is...

Is a special type of cell division necessary for
sexual reproduction.
Explain the genetic mechanisms and molecular basis of
inheritance.

The genetic mechanisms and molecular basis of
inheritance is that genetics deals with the
molecular structure and function of genes, with
gene behavior in the context of a cell or organism
(e.g. dominance and epigenetics), with patterns of
inheritance from parent to offspring, and with
gene distribution, variation and change in
populations.
Explain the flow of energy and the cycling of matter through
biological and ecological systems (cellular, organismal, and
ecological).

The flow of energy and the cycling of matter
through biological and ecological system is the
integrated study of biotic and abiotic components
of ecosystems and their interactions within an
ecosystem framework.
.
Explain how evolutionary relationships contribute to an
understanding or the unity and diversity of life

The evolutionary relationships contribute to an
understanding or the unity and diversity of life is
the cycling of matter and flow of energy in living
systems.
Explain the genetic mechanisms and molecular basis of
inheritance.

The genetic mechanisms and molecular basis of
inheritance is that the inheritance of each trait
is determined by "units" or "factors" that are
passed on to descendents unchanged.
Explain the structure and function of ecosystems and
relate how ecosystems change over time.

The structure and function of the ecosystems
is the characteristic structure of an
ecosystem is obtained by the systematic
physical organisation of the abiotic and
biotic components of that particular
ecosystem.

Biotic- Living

Abiotic- Non-living
Describe how human activities can impact the status of natural
systems.

Human activities can impact the status of natural
systems by a great increase of phytoplankton in a
water body. Negative environmental effects
include hypoxia, the depletion of oxygen in the
water, which induces reductions in specific fish
and other animal populations.
Describe a foundation of biological evolution as the change in gene
frequency of a population over time.

A foundation of biological evolution as the change
in gene frequency of a population over time is a
remarkable amount of biological diversity
appeared over approximately 10 million years.
Explain did natural selection and other evolutionary
mechanisms account for the unity and diversity of past and
present life forms.

The natural selection and other evolutionary
mechanisms account for the unity and diversity
of past and present life forms by a process in
which there is differential survival and/or
reproduction of organisms that differ in one or
more inherited traits.
Summarize the historical development of scientific theories
and ideas, and describe emerging ideas.


The historical development of scientific theories
and ideas is to test them and try to figure them
out.
The emerging ideas are ideas that come straight
to their minds and they are good ideas.
