1. Practical lesson № 2
Morphology of a cell. Structural
components of cytoplasm and a
nucleus.
Cell membranes. Transport of
materials across cell membranes

2. II. Control questions:
1. The Cell Theory in its modern form. Importance
for medicine.
2. Organelles, their structure and functions.
3. Structure and property of cell membrane.
4. Chemical composition of cell membrane.
5. Function of cellular membrane Compartmentcy.
6. General characteristic of transport across cell
membrane.
7. Intercellular contacts.

3. Home work: I. to draw ultrastructure of the
eukaryotic cell.

4. II. To draw the chemical model of a plasmalemma.

5. Classification of organells

6. Non menbrane organells

7. Structure of biological membrane

8. Transport across the membrane

9. Intercellular contacts

10. Auditorial wok (class work)
II. Chloroplasts in cells a leaf of a plant.
Place a part a leaf of an alga in a drop of water on a
microscope slide, cover integumentary glass. Find cells
with a small amount of chloroplasts. Pay attention to
locomotion of cytoplasm. Sketch at the big augmentation
some cells; specify a cellular wall, cytoplasm,
chloroplasts.

11. II. Plasmolisis in plants cells
A. Pell from the onion internal side a skin by the pincers. Cut off a 3-4 mm
of the onionskin by the scissors and prepare provisional specimen.
Examine a specimen with a microscope. During microscopic examination
you observe rectangular long cells. Sketch.
B. Repeat preparation of provisional specimen. Use hypertonic solution in
place of water. Examine a specimen with a microscope during 15 minutes.
Sketch the cells in the hypertonic solution. Mark: cell wall, nucleus,
cytoplasm, cell membrane, vacuole.
