Cell Specialization

Cell Specialization

• Textbook 5-3

2
Questions

• What types of specialized cells are shown?
• What different functions do they carry out?
• Do neurons work together in a system in the body?
• What advantages do specialized cells give to a
  multi cellular organism?

3
Figure 5-8

• Figure 5-8 shows two examples of specialized
  cells macrophages and neurons.
• Macrophages help protect the body from disease.
  Neurons carry impulses throughout the body.
• Neurons work together in the nervous system.
• Specialized cells allow a multi cellular
  organism to accomplish complex tasks.

4
Levels of Organization

• What are the levels of organization that you see
  in Figure 5-9?
• C----------------
• T--------------

5
Levels of Organization

• Cells
• Tissues
• Organs
• Organ systems
• Organism

6
Levels of Organization

• What are specialized cells?
• Cells that are uniquely specialized to carry out
  certain tasks.

7
What are the levels of organism shown in figure
5-9 in order of complexity?

• Specialized cells
• Tissues
• Organs
• Groups of organs
• Organ systems

Xerox- Cell specialization and Organization

• A. nuclear membrane
• B. cytoplasm
• C. mitochondria
• D. endoplasmic reticulum
• E. ribosome
• F. vacuole
• G. cell membrane

9
1. In common..
.these cells have cytoplasm, nucleus, nucleolus,
mitochondria, nuclear membrane, endoplasmic
reticulum, Golgi Apparatus, ribosomes,
vacuoles.basically everything
10

• The amount of these structures varies based on
  the exact function of the specialized cell!

11
2. The many dendrites are used to receive
impulses. The single axon is used to send an
impulse.Label Axon (going down)Dendrite (many
going in)
12
3. This cell is found in the eye. It is a rod
cell. It has light-sensitive membranes.
13
4.

• Do this question and I will check it when I
  collect the paper!

A
14
5.

• The most abundant structures are the ribosomes
  and the endoplasmic reticulum

15
6.

• The function of this cell is to make and excrete
  proteins.
• These proteins are used for digestion of food.

16
7.

• The egg cell is going to have lots of vacuoles
  for storage.
