Cells In Tissue Organs And Sytems Flashcards
Living things consist of different types of cells which are found in many different
Shapes and sizes and carry out different functions
In plants what can take place only when the number of cells increases until a certain age
Growth
Explain the process through which the increase in cells takes place
The increase in cells takes place through a special process during which a mature cell divides into two daughter cells which in turn grows into maturity and subdivide.
Not all the cells of a multicellular plant or animal are
Similar
During the early stages what does the enzymes(chemical substances that control different processes in cells) ensure
It ensures that cells develop in such a way that they differ from one another in structure and is one of the reasons living organisms look different.
The differences in the cell development from other cells in structure is known as……… And are aimed at giving cells specific functions in other words, the cells are….
Differentiation, Specialized
Cells are adapted and have different shapes and structures to perform different…….
Functions
Some cells protect the body against the
Invasion of germs like skin cells
Some cells play an important role in
Transportinv substances like red blood cells that transport oxygen
Some cells carry impulses to and from the
Brain like nerve cells(neurons)
Some cells can contract and relax
Like muscles cells
List the 7 types of cells and draw a diagram of them
1 blood cells, #2 surface epidermal cells, #3bone cell, #4nerve cell, #5 cardiac muscle cells,#6 skeletal muscle cells, #7 smooth muscle cells
There are 2 types of celled organisms
Single-celled organisms and multicellular organisms
Microscopic organisms such as…….,…… and………. normally consist of a single cell are reffered to as……
Bacteria, the amoeba and certain algae.
Unicellular
How does bacteria look like
Bacteria can have three basic shapes: spheres or ball-shaped (cocci bacteria), rod-shaped bacteria (bacilli), and spirals or helixes (spirochetes).The size of bacteria is measured in micrometers. To see bacteria swimming, a 400x magnification is required.
