Diversity of Life 1.4
Learning Target: Protists are a diverse group of organisms.
Learning Target: Protists are a diverse group of organisms.
Review:
Organisms are grouped into six kingdoms.
Bacteria are single-celled organisms without a nucleus.
Viruses are not living things.
Part 1
What is a protist?
Protists include the most complex organisms found on earth.
Protists include all organisms with cells having nuclei and not belonging to the animal, plant, or fungi kingdoms.
Protists are considered a collection of leftover organisms. As a result, protists are the most diverse of all the kingdoms.

Part 2
Most protists are single-celled, microscopic organism that live in water. However, protists also include some organisms with many cells. These organisms are called multi-cellular.

Part 4
Given the many different types of organisms grouped together as protists, it is no surprise that protists play many roles in their environments. Algae are producers. They obtain energy from sunlight. These protists also produce oxygen, which is beneficial to many other organisms. Other protists act as parasites and can cause disease in many organisms, including humans.
Protists live in any moist environment, including both freshwater and saltwater and on the forest floor.

Part 5
Protists obtain energy in three ways.
Some capture sunlight and convert it to energy. (ALGAE)
Another group gets its energy from eating other organisms. (Protozoa)
The last group obtains energy by absorbing materials and nutrients from its environment. (Decomposers)
ALGAE
Plantlike protists, called algae, get energy from sunlight. Like plants, they use the Sun's energy, water, and carbon dioxide from the air or water. Algae contain chlorophyll, a green pigment that they use to capture the Sun's energy. In the process of transforming energy from sunlight, alsgie release oxygen gas into the air. This important process is called photosynthesis.
All organisms that drift in water are called plankton.
Protozoa
Protists that eat other organisms are animal like and called protozoas. Protozoas must move around to obtain the energy they need to survive. They move in three ways.
1. Flagella
2. Cilia
3. Pods
Decomposers
Protists that absorb food from their environment can be called funguslike protists. These protists take in materials from the soil or other organisms and break materials down in order to obtain energy.
