DNA: the genetic material
must have certain characteristics to explain
the properties of life.
First, the genetic material must be able to
code for the sequence of amino acids in
proteins and control protein syn

Structure and Function
When discussing structure and function, biologists distinguish
anatomy from physiology.
Anatomy is the study of the form of an organisms
Larger body size does not
mean bigger cells.
an ensemble of cells, not
necessarily identical, but from
the same origin, that together
carry out a specific function.
The study of tissues.
TYPES OF ANIMAL
CELL DIVISION MECHANISM
Each species (non-reproductive body cell)
has a characteristic chromosome number:
Human somatic cells= 46
In gorillas= 48
In cabbage cells= 20
In pea plants= 14
Adders-tongue fern= 1262 chromosomes
Types of Cell
Prokaryotic and Eukaryotic Cell
- Are built from cells and generally have the
Membrane enclosed units
Filled with cytosol
Has the ability to create copies of themselves
Contain genetic material
Characteristics of Living Things
Caraga State University
Organism are built by assembling
large molecules, much as house is
assembled from building blocks
Living organisms are manifestations

- as a science, biology also uses scientific method in
solving or investigating a biological problem; a systematic
way of solving problems
- systematic process because it involves sequence or
series of steps
