Protozoo
Cell Structure
Plasma membrane
Cytoplasm
Genetic material
What is the function of the plasma membrane?
It diferenciates the inner environment of the cell from the outside… As a filter for substances…
·What is the Eukaryotic cell unicellular, multicellular or both?
both
·What is the genetic material?
-Is the part of the cell which has the information to make structures. In some cells we can find membrane-bound that made up the nucleus.
·Where can we find organelles?
-In the Eukaryotic cell, specifically in the cytoplasm.
-What’s the smallest type of cell?, what’s approximately it’s size?
Bacterium 1mm : 1000
-Examples of multicellular organisms:
Animals and Plants
-Examples of one-celled organisms:
Protozoa, Bacteria and Some algae
What are the characteristics of the bacteria?
Lack of a nucleus
Bactria wall
Small shape
Characteristic shapes
Appendages
The size of a cell change if the animal is bigger or smaller?
No
The structure of the plant cell
Cell wall
Chloroplasts
Vacuole
Nucleus
Cell mabrane
Cytoplasm
What type of cells are bigger: Animal or Plants?
Plant cells.
What is the biggest cell in the human body?
Egg
Where is produce chemical reactions?
Chemical reactions is produce in the cytoplasm
What are chemical reactions?
Chemical reactions hapened when cells interact into another and reproduce, this process hapened in the cytoplasm.
What is the cytoplasm?
The cytoplasm is the internal part of the cell where chemical reactions are reproduced, its mostly made of water, inside there are dissolved subtance and inside the cells there are membrane ound call organelles.
Why substances are dissolved in the cytoplasm?
Because of the Chemical Reaction.
Who cells are organized and carry together?
Cells are organized into tissues and together carry out a specific function, in the organismand many tissues into functional structures that are know as a organ.
What are and make the cells?
. The cells are the structure that makes a chemical reaction.
How many cells are requiered to form a living organism?
Many microscopic living organisms are formed by a single cell.
Bacteria are eukaryotic cell or prokaryotic cell?
Bacteria are prokaryotic because they do not have a nucleus.
How it is called the object that we use for see things that we can not see with our eyes? (for example: cells)
The object is called light microscope.
