Question

1) Your research team has discovered a new single-celled organism in the San Francisco Bay. By microscopy, you find that the organism contains mitochondria. Based on what you know so far, this organism could be:

Select one:

a. an animal, but not a plant, fungus or bacterium

b. a bacterium, but not a plant, animal or fungus

c. a plant, a fungus or an animal, but not a bacterium

d. an animal, plant, fungus or bacterium

e. a plant or animal, but not a fungus or bacterium

2)

Your research team has discovered a new single-celled organism in the San Francisco Bay. By microscopy, you find that the organism has a cell wall (although you don't know yet what the cell wall is made of). Based on what you know so far, this organism could be:

Select one:

a. a plant, a fungus, or a bacterium

b. a plant or a fungus, but not a bacterium

c. a plant or a bacterium, but not a fungus

d. a bacterium, but not a plant or a fungus

e. a plant, but not a fungus or bacterium

3)

Which of the following components are common to ALL living cells? Check all that apply.

Select one or more:

a. plasma membrane

b. ribosomes

c. endoplasmic reticulum

d. cell wall

e. nucleus

f. mitochondria

g. RNA

h. DNA

Answer 1

Question-1,e is correct answer because mitochondria are present in plant and animal but not in fungus and bacteria.

Question-2,cell wall is outer protective covering which may be flexible or rigid . Cell wall is found in plants ,bacteria and plant so a is correct answer .

Question-3,DNA ,RNA, plasma membrane and ribosome are common to all.

Endoplasmic reticulum is found in eukaryotes like plants and animals.

Cell wall is not found in animals.

Nucleus is only found in eukaryotes not in prokaryotes.

Mitochondria is not found in prokaryotes
