• Remember: I can identify the key cell parts that characterize an animal cell.
• Understand: I can define and differentiate between a native animal and an exotic species.
• Analyze: I can explain the mechanism by which an exotic species can out-compete and threaten a native species.
• Understand: I can define and provide examples of the survival strategies camouflage and mimicry.

Homework 2.4

What kingdom lacks a nucleus?

1. Bacteria
2. Plants
3. Animals
4. Fungi

The photo shows 2 sea sheep, a sea slug that's 1 cm big.
This slug is very special, it can perform photosynthesis, something other animals can't do.

Say you would look at cells of this slug.
What will you probably find in the cells that would make you think it's not an animal?
How would you still be able to tell the cells are from an animal?

Toadstools are only a part of fungi.
What is the name of the biggest part of a fungi that is found in the ground? (1 word, singular)

Jack has forgotten about his lunch. He left it in a plastic bag for about a week. When he finds it, it is covered in mould.
Even though the plastic bag hasn't been opened, mould still managed to grow on it.
Explain: how is this possible?

Yeast is a(n) ..a.. fungi
it reproduces using ..b..

1. a. unicellular b. spores
2. a. multicellular b. spores
3. a. unicellular b. cell division
4. a. multicellular b. cell division

Characteristics of animals

Animals are multicellular

All animal cells have:

• NO cell wall
• Nucleus

cell membrane

nucleus

cytoplasm

If you don't know these parts anymore.

Be sure to go back to 1.3

It is expected that you know the names and functions of these organelles

!

Think-Pair-Share

• Think: Work on the assignment on your own.
• Animals reproduce in many different ways, which ways do you know?

• Pair: Discuss and compare with your neighbour, improve your answer
• Share: Talk about given answers during plenary session.

Reproduction in animals

Most animals > Sexual reproduction

For example:

• Mammals: Live birth 
• Birds: Laying eggs

Some animals > Asexual reproduction

For example:

• Some lizards: parthenogenesis 

Reproduction in which two parents are needed.

Their offspring has a mix of their DNA

Reproduction in which only 1 parent is needed.

Their offspring has a copy of their DNA

This is just an example! you don't need to know this!

Female lizard lays eggs that have not been fertilized by a male lizard

Native and exotic

Animals can be native or exotic (sometimes both)

• Native = It normally lives in the area it is found in

Example: the mallard is native to the Netherlands

• Exotic = It originally doesn't belong in the area it lives in

Example: The rabbit is an exotic, it didn't originally live in the Netherlands

Sometimes exotics are counted as native animals, the rabbit is a good example of this.

• Invasive exotic = It also creates problems in that area

Mallard

Camouflage

Mimicry

having colours that make you blend into the surroundings

Imitating other objects or organisms

A hoverfly imates a wasp.

It can't sting but other animals will think it can and leave it alone.

A leaf insect looks like a leaf.

Other animals don't notice it and leave it alone

This owl looks just like the bark of this tree

This lizard looks just like the bark of this tree
