• Investigate the great variety of body plans and
internal structures found in multicellular
organisms.
• Investigate the great diversity among organisms.

Monday we talked about many
of the aspect of living things.
body plans - the general structure each individual organism
assumes as it develops
internal structures – body structure elements within an
organism
multicellular organisms - organisms that consist of more than
one cell
Diversity of life - variability among living organisms
Invertebrate - animals that do not have a backbone, or any
other types of bones
Vertebrate - animals that have backbones
Vascular Plant – can conduct water
Nonvascular Plants – cannot conduct water
Highlights (plants)
Let’s watch this short video
and then do a quick review
before moving on.

Classifying Organisms
takes practice. Let’s go to
NOVA and try together
by doing this interactive
activity together.

Animals
The animals can be broken into two main groupings.
Invertebrate - animals that do not have a
backbone, or any other types of bones, like a
snails, earthworms, beetles or star fish
Now let’s play and animal
classification game
• Go to:

• Click Games and then click North American Forest
Vertebrates – animals that have a backbone, like
frogs, snakes, birds, and mammals
Reproduction (Asexual/Sexual)
Gas Exchange - “aka” respiration
• Species in the Animalia Kingdom can reproduce either sexually (with the genetic
information from two parents) or asexually with the genetic information from a
single contributor.
• Integumentary exchange - gases diffuse across the skin or body
covering, e.g.: flatworms, earthworms, and amphibians.
• Examples of a sexual reproduction include:
– budding - sponges and hydras
– fragmentation - flat worms
– parthenogenesis - whiptail lizards
•
Sexual reproduction can be broken down further as well.
– Internal fertilization
• egg and sperm combine inside of an organism
• usually takes place in the female
• mammals, reptiles, birds, some amphibians and fish
– External fertilization
• takes place outside of an organism
• most amphibians and fish
• Tracheal respiration - animals with hard coatings have small holes in
their body covering. An empty tube runs through the body covering and
into the tissue for oxygen to come in and carbon dioxide to go out, e.g.:
spiders and some insects.
• Internal gills – are gills are at the back of the mouth that allow gas
exchange between water and blood vessels, e.g.: fish.
• External gills – are gills that project out of the animal and into the water,
e.g.: insects and some amphibians.
• Lungs - a lung is an internal respiratory surface in the shape of a sac or
cavity that allow oxygen from the air is absorbed into blood vessels, and
carbon dioxide from blood vessels is released into the air, e.g.: mammals,
birds, and reptiles. Some fish and amphibians also use lungs & gills.
Body Plans
• Asymmetry—Asymmetry means that an organism does not
have symmetry. Asymmetric bodies do not have regular,
predictable shapes, and it is the simplest type of body plan.

Body Plans
Body Plans
• Radial Symmetry—Radial symmetry is a type of symmetry in
which several planes divide an organism into almost identical
parts and have more than one line of symmetry. Organisms with
radial symmetry have no "left" or "right" sides, but they do have
a "top" and a "bottom".
• Bilateral Symmetry—Bilateral symmetry is a
kind of symmetry in which a single plane divides
an object into halves that are roughly mirror
images of each other. radial symmetry either move
very slowly or do not move at all for most of their
lives.
• One of the most important features to develop as
part of bilateral symmetry is the head. The head is
the result of nervous tissue and sensory organs that
are concentrated on the end of the organism that
faces the direction of locomotion.
Digestion
Digestion
• All living things require energy. Animals accomplish this by consuming other
organisms and breaking that down into raw materials.
• Most animals possess a complete digestive system, or a one-way digestive tract.
These animals have a separate opening for food, the mouth, and wastes are
expelled through the anus. So, food travels in one direction and does not mix with
wastes. Vertebrates, insects, and mollusks have complete digestive systems
• In simple animals, such as sponges, digestion takes place within individual cells.
Sponges do not possess true tissues or organs. So, digestion takes place at the
cellular level.
• Other organisms have what is called an incomplete digestive system. It is also
referred to as a two-way digestive tract. Organisms with incomplete digestive
systems have a single opening through which food enters; wastes are expelled
from the same opening. Jellyfish and flatworms display this type of digestive
system.
• Most animals possess a complete digestive system, or a one-way digestive tract.
These animals have a separate opening for food, the mouth, and wastes are
expelled through the anus. So, food travels in one direction and does not mix with
wastes. Vertebrates, insects, and mollusks have complete digestive systems
Circulation
• As organisms become larger and more complex, they require a system of
transferring gases and nutrients to all parts of the body.
• The simplest is an open circulatory system. Insects have open circulatory
systems. Blood and body fluid mix to form a substance called haemolymph. The
size of the organism is limited because this system is not very efficient.
• Closed circulatory systems are the most efficient at transporting nutrients and
gases to all parts of the body. Earthworms are the simplest animals with a closed
circulatory system.
• All vertebrates have closed circulatory systems with true hearts. Fish have the
simplest heart, containing only two chambers.
• The vertebrate heart continued to evolve to become more efficient. Humans have
a four chambered heart.

Let’s play a game to see what specific traits in
different animals you can identify.

• Go to:

• Drag a trait into the correct bucket.
• If it falls out you must try again.
• Once you have filled the bucket correctly the
animal will appear!
