UNIT 1 - CHARACTERISTICS OF LIFE

Using your awesome powers of imagination and observation – Pretend that on your desk in front of you is a Petri dish with the following items in it. Write down six observations of each of these objects.

List Similarities AND List differences between the items

Below, create a list of the Characteristics of life based on your observations above

ALL LIVING THINGS:

.

• .

• .

• .

• .

Living things are made up of cells

Unicellular =

Multicellular =

Living things Reproduce

Asexual Reproduction:

Sexual Reproduction:

Living things Grow and Develop

Most living things go through a cycle of change called development

Then comes aging where reproduction stops

lastly inevitably comes death which is also a process that separates living from non-living things

Living things obtain and use energy

Anabolism:

2 Photosynthesis in plants

Catabolism:

1 digestion in animals

Metabolism:

Living things Respond to their Environment

The ability of living things to respond to stimulus is called irritability

Homeostasis:

Building your understanding of concepts: (#2, 3only)

2. Name and explain a feature of the human body, other than temperature that must be regulated to maintain homeostasis?

3. Why don’t all members of the same species have equal survival chances?

TYPES OF CELLS

Cells come in a variety of shapes and sizes that suit their diverse functions.

Lab: Why are Cells So Small?

MOST CELLS ARE SMALL FOR TWO REASONS:

#1-

#2 -

COMPARING CELLS

All cells share common features, such as a plasma membrane, cytoplasm, ribosomes, and genetic material (DNA).

But there is a high level of diversity among cells, there are significant differences between prokaryotes and eukaryotes. In addition plant, fungi and animal cells have differences, although all plant, fungi and animal cells are eukaryotic cells. (so are Protista cells but they are unicellular organisms)

EUKARYOTIC vs PROKARYOTIC CELLS

1. Prokaryotes differ from eukaryotes in that

2. In place of a nucleus, prokaryotes have

3. Prokaryotes lack

UNICELLULAR ORGANISMS such as bacteria and their relatives are Prokaryotes.

KINGDOM:

All other organisms are Eukaryotes; Kingdoms: .

The difference between Prokaryotes and Eukaryotes is such an important distinction that Prokaryotes are placed in Two Domains Separate from Eukaryotes - Domains Bacteria and Archaea.

Cell Theory:

• The three scientists involved were _________________, _____________________, _________________

• The three statements of the cell theory are:

o _________________________________________________

o _________________________________________________

o _________________________________________________

Cell Membrane Basics:

• All cells have an outer edges marked by ________________________ which plays a critical role in _____________________________.

• The structure of all cell membranes includes _________________and ____________________

• Variations of the cell membrane result because cell _______________ are not the same and since the synthesis of both lipids and proteins are coded for within a cells gene, these structural differences crease _________________________ differences.

• Cytoplasm is ________________________ and is composed of mostly _____________with some ________________________________________________________required to maintain the cell’s _____________________________________________

Cell Genetics:

[pic]

• Chromosomes are made out of _________________ and sections of a chromosome that code for a protein are called _____________.

• Proteins form many cell structures such as __________________ components of the membrane, etc.

Cell Walls:

• Not all cells have cell walls. ______________have no cell walls

• Cell walls are generally composed of linear ___________________ either ________________ in plant cells or ______________ in fungi cells

Answer the Review Questions on Page 12 below:

1. Protoplasm includes ___________________________and _______________________________

2a. Feature of the cell membrane that controls the movement in and out of a cell is ____________________________________

2b. The presence of this feature is determined by ____________________

Discussion:

2. How can variations in cell function be explained genetically? ______________________________________________________________________________________________________________________________________________________________________________________
