Organelles and Cells

• Organelles are the parts of cells that have specific jobs, such as the nucleus or golgi apparatus

• Prokaryotic Cells are bacteria = no nucleus

• Eukaryotic Cells are either plant or animal cells = have a nucleus

• This is the level of organization where life begins!!!

Multiple Choice

• eukaryotic

• prokaryotic

• plant

• animal

Multiple Select

Eukaryotic cells include:

• bacteria

• virus

• plant

• animal

Multiple Choice

Eukaryotic cells have a nucleus.

• True

• False

Multiple Choice

What is a "cell part" called?

• organelle

• tissue

• organ

• cell part

Tissues

• A tissue is a group of cells that work together

• Examples = bone or nervous

• More complex than cells

Organs

• An organ is a group of tissues that work together

• More complex than tissues

• Examples= heart, brain

Organ System

• A group of organs that work together

• More complex than an organ

• The human body has 11 organ systems!

• Example= digestive system

Organism

• Formed when the body systems work together

• You are an organism!

Multiple Choice

Which is in the proper order?

• organ, tissue, organism, cell

• cell, organ, tissue, organ system

• cell. tissue, organ, organ system

• tissue, cell, organ, organ system

Population

• A group of the same organism living together

• A gaggle of geese

• A pride of lions

Community

• Different populations of living things, living together

• Pond = frogs, fisg, cattails,e tc...

Ecosystem

• All the living and non-living thins in an area

• Biotic=living

• Abiotic=non-living

• Plants+ Animals+ Rocks+ Water

• Examples= forest, pond

Multiple Choice
