LEVELS OF ORGANIZATION

• Have specialized cells to perform specific jobs
• The shape of the cell is designed for its job

Red blood cells
Nerve cells
Cardiac cells
Liver cells
4
As you know, all living things are made of cells.
We have looked at two types of cells
Typical LEAF Plant Cells NOT root, stem or
flower!!!!
Typical SKIN Cells not nervous, muscle, bone,
etc
But not all plant cells are rectangular and not
all animal cells are circular!!!!!!!!!
5
LEVELS OF ORGANIZATION

• The shape of the cell is designed for its job

Onion stem cells
Onion skin cells
6
Bone Cells

• Bone cells are circular and stack on each other
  to make the bone strong.

7
Nervous Cells

• Nervous cells are shaped like wires to carry
• electrical impulses.

8
Red Blood Cells

• Red Blood Cells have a space or hole in the
  middle to carry oxygen. Why do organisms need
  oxygen?

9
Muscle Cells

• Muscle cells look like rubber bands that contract
  when they get the impulse from the nerve.

10
Skin

• Function Flat to stack on each other and
  protect the body.

11
Leaf

• Function Hard brick to stack on each other and
  make the plant stand up. The vacuole pushes
  against the cell wall.

12
White Blood

• Function Shaped like a blob to engulf foreign
  objects in the blood.

Why do red and white blood cells look different??

Unicellular vs. Multicellular

• Unicellular One celled organism. They must
  perform all activities within one cell. NO
  TISSUES, ORGANS, OR SYSTEMS!!

19
Multi-cellular Organisms

• Multi-cellular Organisms made of more than one
  cell. The cells work together to make tissues,
  organs, and organ systems.

20
Unicellular vs. Multicellular

• Similar
• Carry on all 7 characteristics of life.
• Have the same MAIN cell parts as multi-cellular
  organisms. Mitochondria, vacuole, ER, nucleus,
  ribosomes, chloroplast, golgi bodies, etc. Except
  nucleus in Arachebacteria and Eubacteria
• Different
• Cells in multi-cellular organisms have a specific
  job. Unicellular organism must carry on all 7
  characteristics of life in one cell.
• 2. Multi-cellular organisms have tissues,
  organs, and organ systems. Unicellular organisms
  DO NOT.

21

PLANT TISSUES
Plants are also made up of cells. These cells
form tissues and organs just like animals.
There are three basic organs in any plant. These
organs are the roots, the stem and the leaves.
Each one is made up of tissues that perform
different functions to keep the plant alive.
61
PLANT TISSUES AND ORGANS
Stems support the above ground parts of the
plant. Transports food and water between the
leaves and the roots.
Stems help the other two types of plant organs by
holding the leaves up so they can receive maximum
sunlight. Stems also transport water from the
roots to the leaves and transport food from the
leaves to the roots.
