Lessons 4-5 NotesCreating A Pond and Exploring Cells

Macro vs. Micro• Macroorganism – an organism that can be

seen with the naked eye. (Example: Blackworm, Raccoon, Fish)

• Microorganism – any organism to small to be viewed without a microscope (Example: bacteria, protists, some fungi and algae)

Habitat vs. Ecosystem• A habitat is the home of a single type of organism.

(House)– For example, blackworms live in the muddy fringes of a pond,

but Lemna (an aquatic plant) will have a habitat on the surface of the water.

• Ecosystems are home to more than one type of organism. (Town)– Contains many habitats that share resources (water, land,

vegetation). A pond is an ecosystem.• An organism’s niche is the job they perform naturally

within the ecosystem to keep the ecosystem functioning.– In a pond, frogs and birds consume insects to keep the number

of them from becoming too high.

The Pond Ecosystem• The living components (animals, fungi,

microorganisms) of an ecosystem are referred to as a community.– In a pond, the community of organisms consists of

blackworms, dragonflies, and Lemna (free floating aquatic plant)

• The members of each species in a community are called a population.– All of the blackworms in a single pond community

make up the blackworm population there.

Plant Cell vs. Animal Cell

• Nucleus• Cell membrane• Endoplasmic

reticulum• Mitochondria• Golgi body• Ribosomes

• Chloroplasts• One central

vacuole• Cell wall• More square

in shape

• Many smaller vacuoles

• More round in shape

Remembering the Organelles• Golgi Body – GB PACKERS – The Golgi Body

packages proteins.• Ribosomes – Rib – Ribs are protein and the

ribosomes make proteins.• Mitochondria – Mighty Mitochondria – break

down nutrients to create energy.• Lysosomes – Lys Slice – break down/digest

proteins.• Vacuole – Vacuum – storage.
