Unit 6

Unit Title: Living Systems
Unit Time Frame: 8-9 Weeks

Unit Overview
Students will learn that living systems interact
at all levels of organization.

Essential Learning
How do cells, tissues, organs, and organ
systems work together to serve the organism
as a whole?

What are the different types of reproduction in
plants and vertebrates?

What is the difference between a sperm cell and
egg cell and how do they relate to plants
and vertebrates?

What are the developmental stages of an
embryo?


Key Concepts(*) SLE repeated with plants
Illustrate the hierarchical relationships of cells,
tissues, organs, and organ systems.

Analyze how two or more organs work
together to perform a function.

Analyze the structure and function of tissues,
organs, and organ systems of a vertebrate and
an angiosperm using various models or methods
of dissection. (*)

Explain the role of reproduction in the continuation
of a species.

Differentiate between sexual and asexual reproduction
in vertebrates and plants.

Identify the number and source of chromosomes
in human body cells.

Identify the number and source of chromosomes
in human sex cells.

Explain the role of cell division.

Explain that the fertilized egg cell carries genetic
information from each parent and multiplies
to form a complete organism.

Distinguish between sperm cells and egg cells.

Compare and contrast the structure and function
of the sperm cell and the egg cell in vertebrates
and plants and their role in sexual reproduction.

Investigate and analyze the development of embryos.

Dissect a poultry egg to analyze its structure
(e.g., paper, plastic, or clay models, virtual dissection,
or specimen dissection).

Identify organ systems in vertebrates and plants.

Summarize the interactions between organ systems
in the maintenance of homeostasis.

Relate the structure of vertebrate and plant body
systems to their functions.

Compare and contrast vertebrate systems and
plant organ systems.

Identify human body systems: nervous, digestive,
circulatory, respiratory, excretory, integumentary,
skeletal/muscular, endocrine, and reproductive.

Investigate functions of human body systems.

Describe interactions between major organ
systems.

Dissect a flower to analyze the reproductive
system of angiosperms.

Differentiate between sexual and asexual
reproduction in vertebrates and plants.

Identify organ systems in vertebrates and plants.
