Specialisation of cells

In our biology class, we are studying the cells. I worked with Pancho

1.Ciliated cell
pseudo2

The respiratory system is coved with tiny hair. this makes the cell move and moves the mocus from oone place to another. The cilia is the adaptation.

2. Root hair cells

This cell absorves water and minerals.  The absorption of water through the surface area. The cell has hair to protect it.  Does not has chroloplats because they are under the grass, so ther don’t make photosintesis.

3. Xylem vassels

small (1)

The adaptation is that they are connected to each other and have a long narrow tube to transport water and mineral salts. Doesn’t have a nucleus nor cytoplasm. Its a tissue, a group of cells. This transport water.

4. Palisade mesophyll cells

The adaptation is that they have lots of chloroplasts which contain chlorophyll which is used for photosynthesis. This are in the leaves of the cell.

5. Nerve cells
nervecell

The adaptation is that it has axon buttons which can join to different parts of our body to transmit information in the form of electrical impulses. This transmite information as electrical impulces. Its long to transmit information across  long distances.

6. Red blood cell

red-blood-cells

Its small size lets red blood cells pass through narrow capillaries and provides a large surface area, allowing rapid diffusion of oxygen. This transports oxygen, and is on the circulatory system. Has a picment called  haemoglobin. does not have nucleus.

7.Sperm and egg cell

The adaptation is that the head contains genetic information and an enzyme to help penetrate the egg cell membrane.

    Hi!
    The activity about cell structure is still missing.
    ( Venn diagram and functions)

    Hi !
    The activity is incomplete.
    You have to state the adaptations first, and then relate the structure to its function.
    Please, complete it.
    Regards
