Name one organelle that can be found in a plant cell
Name one organelle that can be found in a plant cell
Either:
- Cell wall
- Cell membrane
- Chloroplasts
- Vacuole
- Nucleus
- Mitochondria
- Rough and smooth ER
- Golgi body
- Ribosomes
Name the labelled organelles
Name the labelled organelles
A - Cytosol
B - Vacuole
C - Nucleus
D - Cell wall
What is the role of the cell wall in a plant cell?
What is the role of the cell wall in a plant cell?
Protection from outside bodies and it helps the cell to maintain it's shape
By what process do plants create energy?
By what process do plants create energy?
Name and state the function of 1, 6 and 7.
Name and state the function of 1, 6 and 7.
1 = Nucleus. The boss of the cell. Controls all functions.
6 = Vacuole. Storage for excess water and waste, provides support in plant cells. When the vacuole fills up with fluid it creates turgidity (pressure) and pushes against the cell wall, helping the cell to remain strong.
7 = Chlorplast. Responsible for photsynthesis. Contain cholorphyll which absorb sunlight.
What name do we give to the building blocks of all matter?
What name do we give to the building blocks of all matter?

The above picture is representing a solid. By what process does this solid change to a liquid? By what process does a liquid change into a solid?
Melting.
Freezing (solidification).
What are the atomic numbers of the elements below?
What are the atomic numbers of the elements below?
Point to the eyepiece on the microscope below
Point to the eyepiece on the microscope below
The cylindircal black piece at the top.
True or false?
It is correct procedure to carry the microscope by the eyepiece in one hand and your books in the other hand to the bench.
True or false?
It is correct procedure to carry the microscope by the eyepiece in one hand and your books in the other hand to the bench.
False! - you should always use two hands to carry a microscope, one hand on the arm and one under the base.
Is the microscope shown monocular or binocular?
Is the microscope shown monocular or binocular?
Binocular (like a pair of binoculars - two eyepieces)
Name parts 11, 12 and 8.
Name parts 11, 12 and 8.
11 - stage
12 - focusing knob
8 - lamp
List three differences between the microscopes shown
List three differences between the microscopes shown
Possible answers include:
- one is binocular, the other monocular
- one has the stage raised, the other is at the base.
- the monocular microscope has three focus settings.
True or false?
Every report should begin with an aim.
True or false?
Every report should begin with an aim.
False - every report should begin with a title.
What does the procedure/method section of a report include?
What does the procedure/method section of a report include?
The steps for how the prac/experiment is carried out.
Where does the conclusion go in a scientific report? What should it include?
Where does the conclusion go in a scientific report? What should it include?
At the end. A summary of the aim of the experiment, what was done and what was found. It should also give improvements for future experiments.
This is a students drawing of their slide under the microscope. It is lacking many important features of a scientific drawing. What could you include to make it better?
