Types of Cells

1. List the three parts to the cell theory.

2. Why are cells important?

​

Bell work

SC.6.L.14.2

Investigate and explain the components of the scientific theory of cells (cell theory): all organisms are composed of cells (single-celled or multi-cellular), all cells come from pre-existing cells, and cells are the basic unit of life. 

Quick recall!!!!
what are the ABCs' of the CELL THEORY?

What is a CELL?

• The cell is the most basic unit of structure and

function in livings organisms.

• There are many different types of cells, each with their own specific

function, that act as the building blocks of living organisms.

quick recall!!!! the ABC of the CELL THEORY?

A. All living things (organisms)

are made of one or more cells.

• Bacteria are organisms that

are UNICELLULAR meaning
they live as just one cell.

• Plants and animals are

MULTICELLULAR meaning
they consist of many cells.

B. The cell is the most basic unit of structure and function in a living
organism.

TWO types of cells?
• All cells are classified as one of two types of cells

based the presence of a nucleus or not.

NO NUCLEUS

PROKARYOTE

EUKARYOTE

NUCLEUS

BACTERIA

ANIMAL CELL

PLANT CELL

A) All living things are made up of cells - unicellular or multicellular.

B) Cells are the basic unit of life.

C) Cells divide to make new cells.

• Cells undergo the process of homeostasis that help ​sustain life.

  Cells come in different shapes and sizes.

What we know so far..

Multiple Choice

A plant and an animal are both living things. According to the cell theory, what can you conclude about these two very different organisms?

• Plants have cells but animals do not.

• They both come from the same kind of cell.

• They are both made of one or more cells.

• They both come from a non-living organism.

C. All cells come from pre-existing, living cells.

​Draw a Venn diagram in your notebook and write down the difference and similarities between Prokaryotes and Eukaryotes as you watch the video

Prokaryotes Eukaryotes

What do BOTH cells have in common?

How are PROKARYOTES and EUKARYOTES different?

• The ?

NONUCLEUS

In PROKARYOTES, there is no nucleus. Instead there
is a nucleoid – a region where the DNA floats within
the cytoplasm.

How are PROKARYOTES and EUKARYOTES different?

• The
In EUKARYOTES, there IS a nucleus. A nucleus is a
membrane-bound organelle that contains most of
the cell’s DNA.

NUCLEUS

ANIMAL CELL

PLANT CELL

How are PROKARYOTES and EUKARYOTES different?

• The ?
PROKARYOTES are small and simple. About 1/10 the
size of eukaryote cells.

PROKARYOTE

EUKARYOTE

How are PROKARYOTES and EUKARYOTES different?

• The ?
PROKARYOTES are classified into TWO kingdoms:
BACTERIA and ARCHAEA. Archaea a similar to, but
evolutionarily distinct from bacteria.

How are PROKARYOTES and EUKARYOTES different?

• The ?
EUKARYOTES are classified into FOUR kingdoms: ANIMAL,
PLANT, FUNGI, and PROTIST.

ANIMAL

PLANT

FUNGI

PROTIST

To Do!!!!!!!

Study the structure of the plant and animal cell at the back of the room, draw a side by side picture in your notebook, label all the parts.
This is a GRADED assignment.
