Last lesson of the year!

Let's see what you remember....

Unicellular organisms

• Uni = one
• Unicellular = one cell 

• Functions for life are performed 
    by cell organelles
• Live in aqueous environments   (water)
• Example: Amoeba

1. So are humans and other animals unicellular?

1. Yes
2. No

Levels or organisation 

Levels of organisation

Individual (organism)

Population

Community

Ecosystem

2. What do you study when you study
a population?

1. All life within an area
2. All life + non-living nature in an area
3. All individuals of one species in one area
4. All animals living in an area

The levels of organisation

You can investigate:

1. The relation between an individual and its environment.

2. A population is a group of individuals of the same species in a specific area. 

3. Populations of different species in the same area -> community.

4. An ecosystem: a specific area in which biotic and abiotic factors form a unit. 

Photosynthesis

• Plants take in water,
   carbon dioxide and
   energy from sunlight

• Photosynthesis produces
   glucose and oxygen. 

chloroplasts

• photosynthesis takes place
   inside the chloroplasts
• inside there is a green
   pigment --> chlorophyll

What is the link between cellular respiration and photosynthesis?

3. What is the link between photosynthesis and
cellular respiration?

1. They are opposite processes.
2. There is no relation.
3. Every organism does both.
4. They are the same processes.

Practice test 1.1 - 1.4

4. Which cell organelle controls what happens in each cell?

1. Chloroplast
2. Mitochondrium
3. Nucleus
4. Cell membrane

5. What is the name for the gel-like liquid that fills up the cell?

6. Which cell organelle is the hard, outer covering of the plant cell?

1. Vacuole
2. Cytoplasm
3. Cell wall
4. Cell membrane

7. What is the name for genetic material that can be found in the nucleus?

8. To which organ system does a lung belong?

1. DIGESTIVE
2. REPIRATORY
3. NERVOUS
4. SKELETAL

9. Which cell organelle can only be found in plant cells?

1. Chloroplast
2. Mitochondrium
3. Nucleus
4. Cell membrane

10. Many organ systems together form
a tissue.

1. True
2. False

11. Unicellular organisms have
organ systems.

1. True
2. False

12. Which organ
system is shown here? -->

1. Circulatory system
2. Respiratory system
3. Digestive system
4. Reproductive system
