1 Cells

2 1. Name the parts of the light microscope

3 Name the parts of this microscope
3 4 5 7 8 9 11 12 13

4 2. Describe how to make a preparation of plant cells
Take a thin piece of tissue e.g. onion epidermis Place on the slide Add a drop of water/ iodine stain Place on coverslip at an angle to prevent air bubbles View at low power then high power

5 What do plant cells look like?
Onion epidermis ( X 100)

6 What do plant cells look like?
( X 100)

7 Cells Cell structure

8 Differences between plant and animal cells
Plant cells No cell wall Cell wall No chloroplasts Chloroplasts No large vacuole Large vacuole

9 6. Draw a plant cell under the light microscope.
Label cell wall, cytoplasm, nucleus, vacuole, chloroplast, cell membrane.

10 7. Draw an animal cell under the light microscope.
Label cytoplasm, nucleus, cell membrane

11 Name this!

12 Name this! A B C

13 Identify these cells! In each case give 3 reasons for your answer.
B

14 D C

15 E F

16 Define tissue A tissue is a group of similar cells eg muscle tissue, nervous tissue

17 Some animal tissues Muscle, bone, connective, nervous tissue

18 Plant tissues Dermal tissue Vascular Tissue
A single layer of cells that surrounds the different parts of a plant Epidermis protects the plant Vascular Tissue Transports materials around the plant Xylem transports water and minerals around the plant Phloem transports food from the leaves to the other parts of the plant

19 7. Define organ Several different types of tissue organised together for a particular function e.g. heart, leaf, liver

20 8. List 4 animal and 4 plant organs
Animal organs Heart Stomach Brain Kidney

21 Plant organs Leaf Root Stem Flower

22 9. Define organ system Groups of organs working together for a particular functions Circulatory system

23 10. List 4 organ systems in animals

24 Enzymes Cell structure
