🗑
|
||||
| What are the characteristics of Ciliates? | have cilia covering entire body
used for locomotion and obtaining food
ie. paramecium
🗑

cellular slime moulds
water moulds
🗑
|
||||
| What are the characteristics of plasmodial slime mould? | tiny
slug like
visible to unaided eye
engulfs small particles into their cytoplasm
many nuclei
🗑
|
||||
| What are the characteristics of cellular slime mould? | engulfs small particles
releases a chemical causing them to gather into a pseudoplasmodium when food is scarce
🗑
|
||||

abundant
rigid cell walls with an outer layer of silica
food source for other organisms
🗑
|
||||
| what are the characteristics of dinoflagellates? | 2 flagella at right angles to each other
moves with a twirling motion
reproduces quickly in favourable conditions causing algal bloom
may have a mutual relationship with corals giving it its colour
🗑
|
||||
| What are the impacts of algal bloom? | causes red tides
produces a toxin that accumulates in plankton eating shell fish
may be fatal to humans
🗑
|
||||
| What are the characteristics of euglenoids? | found in shallow fresh water
have flagella
autotrophs in light, heterotrophs in dark
light-sensitive organs
🗑
|

has pseudopods for locomotion and food
free living or parasitic
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
