|
What are flagellas?
|
Flaggella are threadlike tails that whip around to cause movement of some types of cells.
|
|
|
What does the diet of baleen whales mainly consists of?
|
plankton
|
|
|
What are parasites?
|
Cells that do not move on their own. They live in or on other organisms.
|
|
|
What is the function of chlorophyll?
|
Chlorophyll helps plants, and plantlike protists, make food, susing the Sun's energy.
|
|
|
What is pseudopod?
|
A pseudopod is cellular movement that is involved in feeding.
|
|
|
What type of cell structure are most algae?
|
Most kinds of algae are single-celled.
|
|
|
What is at the base of the ocean food chain?
|
plankton
|
|
|
What are many plantlike protists called?
|
algae
|
|
|
How do most protists reproduce?
|
Most protists reproduce by fission.
|
|
|
Give an example of a protozoan and tell how it operates.
|
An amoeba is a protozoan. Amoebas move by pushing out its cytoplasm and forming pseudopods. Amoebas also use their pseudopods to capture food. an amoeba completely surrounds the food and ingests it. Once inside the amoeba, the food is digested and used for energy.
|
|
|
What is fission?
|
Fission is the dividing of a cell to produce two new cells. In this form of reproduction, there is only one parent, and the new cells are identical to the parent.
|
|
|
Discribe protists.
|
Mostly single-celled microscopic organisms that have traits of animals, plants, or both. Most protists contain a nucleus and the other cell structures needed to carry out all basic life functions. Some protists, though, are multi-cellular.
|
|
|
What are cilias?
|
Hairlike structures that proplel a cell and draw water and food cells, such as paramecium.
|
|
|
What is plankton?
|
Plankton includes all the tiny organisms that float freely near the surface of the ocean. It is plantlike plankton that forms that base of the ocean food chain.
|
|
|
What structures is chlorophyll held in?
|
Chlorophyll is held in structures call chloroplasts.
|
|
|
What are protozoans?
|
They are protists that get their energy by feeding on other organisms.
|
|
|
Where do protists live?
|
ponds, lakes, rivers, oceans, damp soil, and even inside other organisms.
