Let's learn about: Eukaryotic cell
Eukaryotic cells are the most modern major cell type. All multicellular organisms including you, your pet and the plants, have eukaryotic cells.
Eukaryotic cells usually have more than one chromosome which contains large amounts of genetic information.
All eukaryotic cells have
|
A nucleus |
 |
|
Mitochondria |
 |
|
Golgi body |
 |
|
Vesicles |
 |
|
Endoplasmic
Reticulum |
 |
There are two types of eukaryotic cells: animal and plant cells which can reproduce sexually or asexually.
|
A nucleus: This contains genetic material
(DNA), and controls the cell's activity. |
 |
Cell Membrane: A flexible layer that surrounds
the cell and controls the substances that enter and exit. |
 |
|
Cytoplasm: A jelly-like substances where the
chemical reactions happen. |
 |
|
Mitochondria: This is where energy is released
from the food moecules. |
 |
Plants are also made up of millions of cells which have a
nucleus, cell membrane, cytoplasm and mitochondria too, but they also contain
the following structures:
|
Cell wall – A hard layer outside the
cell membrane, containing cellulose to provide strength to the plant.
|
 |
|
Vacuole – A space inside the cell that is
used to store substances and help the cell keep its shape.
|
 |
|
Chloroplasts – Structures that contain the green pigment chlorophyll, which is a key part of photosynthesis. |
