there.
The
cell theory
states that
cells
are the
basic units
of all living things
nucleus
is located near the
center
of a cell. It is the control center of the cell and it contains the genetic material
The
cell theory
states that all
living organisms
are
composed
of cells
The cell membrane, which is a thin
coat of lipids that encloses the cell
The cell membrane serves as the boundary between
the inside of the cell and the outside environment
The
cell theory

new cells
are produced from
pre-existing cells
The
nucleus
, which is a
jelly-like
material that encloses and protects the
organelles
The
organelles
, or "
little organs
", which are tiny celluar structures that serve specific functions within a cell
Common
organelles

The nucleus that is surrounded by a double-layered membrane called the
nuclear membrane
or
nuclear envelope
Reproduction refers to the process by which new
organisms are produced from a parent organism
Diploid
is a type of cell that contains the total
genetic materials
present in the species
Haploid
is a type of cell that contains
half
of the total genetic materials present in the species
Pistil
is the female component of a
plant
Ovary
,
stigma
, and
style
is a part of the carpel
Asexual
is a type of a reproduction produces individuals that are highly

community
of
organisms living
together and
interacting
with the
non living
components
Biotic

Abiotic factor
refers to physical environmental conditions such as temperature, light, water, air pressure, soil composition, etc.
pH
refers to the
level
of
acidity
and
alkalinity
Producers
refers to
organisms
that are
capable
of
producing
own
food
Decomposer
refers to organisms that
decompose dead parts
of
living organism
Detritivorce
refers to organisms responsible for
decaying
of matter and reabsorption of
nutrients
back to the soil
Aquatic biomes
comprises
70
% of the earth's surface
Marine
biome has
very high salinity
Desert biome
is considered to be the driest
Tropical
rainforest
biome receives the highest amount of rainfall
tropical rainforest biome
receives
10
to
30
inches of rainfall each year
Tundra
is considered to be the
coldest
and
harshest
of all biomes
Erythrocytes
delivers oxygen gas to the different parts of the body througn
blood flow
commensalism
does not involve
harming
another organism
parasitism
refers to a relationship where one organism
benefits
at the
expense
of other
mutualism
