Cells need energy to sustain life.

Animal cells get their energy

from sugars obtained by

consuming food.

During sexual reproduction two

cells (one from each parents),

each with exactly half a set of

DNA, are combined to form an

offspring with a full set of DNA.

Plant cells need large vacuoles

to store water needed during

photosynthesis and animal cells

do not.

The cell is the basic unit of

structure in living things. This

means that the structure of a living

organism is the result of the cells

that make up that organism.

Organisms that reproduce

asexually have offspring that are

identical to their parent while

organisms that reproduce

sexually have offspring with

genetic material from both

parents.

Prokaryotic and eukaryotic cells

are distinguishable by the

presence or lack of a nucleus.

Cells make tissue, and tissues

work together to form organs.

Plant cells get their energy from

sugar made through

photosynthesis.

Unicellular organisms do not

have tissue, organs, or organ

systems.

All cells carry out similar

functions like extracting energy

from food, maintaining

homeostasis, and getting rid of

cellular waste.

The presence of a cell wall and

very large vacuoles are two

distinguishing characteristics of

a plant cell from an animal cell.

The cell is the basic unit of function in living

things. This means that the various functions

of a living organism are the result of the cells

that make up that organism. For example,

one function of a plant is to convert sunlight

into energy. This function is the result of the

cells that make up the plant.

Autotrophic organisms have

cells with chloroplasts or other

mechanisms for making their

food.

It is correct to say that “all

prokaryotes are bacteria” and

“all bacteria are prokaryotes.”

Muscles are made of muscle

cells.

Skin is made of skin cells.

A liver is made of liver cells.

All cells come from other cells

except for the original cell in the

organism. This original cell

came from the joining of two sex

cells during reproduction.

Cells are made of smaller

functioning parts called

organelles.

One way a plant cell is different

from an animal cells is that it

contains a chloroplast used to

convert light energy into

chemical energy.

The cell theory states that all

living things are made cells.

All cells must extract energy

from food to maintain life.

A chloroplast would never be

found in a heterotrophic

organism.

Heterotrophic cells extract

energy from food they

consumed while autotrophic

cells extract energy from food

they make.

Most living things are composed

of cells.

Each type of cell in a human has a

different and unique set of DNA. For

example, the DNA found in the

nucleus of a nerve cell is completely

different than the DNA found in the

nucleus of a skin cell.

Organisms can be unicellular or

multicultural.

All living things are made of

thousands to millions of cells

working together to form an

organism.

Unicellular organisms are made

of many cells.

Animal cells can be considered

autotrophic.

The cell wall is important to an

animal cells because it helps the

cell maintain its shape and gives

its support and strengths.

All cells and cell types serve the

same function within an

organism.

Animal and plant cells are

prokaryotes.

A major difference in a plant and

animal cell is that the animal cell

has a mitochondria used to

convert sugar into usable energy

and the plant cell does not.

Similarities among all cells are

the presence of a nucleus, a

membrane made of a lipid

bilayer, and the presence of

DNA.
