protist-detailed

Question 1

what are protist?

Answer 1

all eukaryotes that are not animals, plants or fungi and are grouped together

Question 2

what do protist reproduce by?

Answer 2

binary fission[asexual reproduction] and sexual reproduction

Question 3

what are the characteristics/features of protist

Answer 3

1- can be multicellular or unicellular
2- can be heterotrophic or autotrophic
3- contains nucleus and other membraned bounded organelles

Question 4

define autotroph and heterotroph

Answer 4

autotroph
- makes its own food generally by photosynthesis
heterotroph
-find found sources from external environments rather than photosynthesis

Question 5

what is an animal-like protist called, including its features

Answer 5

animal protist are called protozoans and features are
1-they are heterotrophs
2- have mitochondria and digestive vacuole
3- there are 4 types of protozoans
 a] ciliates
 b]flagellates
 c]parasites
 d]pseudopods

Question 6

describe the 4 types of protozoans

Answer 6

ciliates
-contain cilia to move through water and waft algae and bacteria into their mouth like structure

flagellates
-contain flagella to propel through water and capture food particles

parasites
- rely on host cell and has a apical complex to wedge through the host cell

pseudopods[ finger like projection from cytoplasm]
-use the pseudopod for
a] locomotion
b]phagocytosis

Question 7

Answer 7

algae

Question 8

describe features/characteristic of plant-like protist

Answer 8

1- contain cell wall
2- contain chloroplast
3- autotrophs

Question 9

2 example of plant like protist

Answer 9

Answer 11

mold

Question 12

describe the characteristics/features of fungi-like protist

Answer 12

1-contains cell wall made of cellulose
2-use spores to reproduce
3-heterotrophs

Question 13

2 example of mold
