Do mushrooms have cells with nuclei?

Definition

 

 

 

 

Yes, they are fungi and eukaryotic 

Term

Is this cell Eukaryotic or Prokaryotic, how do you know?

[image]

Definition

 

 

Eukryotic because it has a nucleus and a plasma membrane 

Term

 

 

What are the unicellular organisms?

Definition

 

 

Bacteria and Protists 

Term

 

Organisms can be grouped by:

A. Cell number
B. Cell type
C. Both

 

Definition

 

 

C. Both 

Term

 

What is the purpose of reproduction?

Definition

 

 

To pass on genetic materials which is essential for the continuation of the species. 

Term

 

 

How do single celled organisms reproduce? 

Definition

 

 

 

Asexual reproduction- the cell buds or divides to create two cells with identical genetic material.

Term

 

 

 

Is the Zygote resulting from sexual reproduction identical in genetic material to the parents?

Definition

 

 

No it is a combination of genetic material from both parents 

Term

 

 

Where is genetic information stored? 

Definition

 

 

 

DNA Molecule 

Term

 

 

What are genes and where are they found?

Definition

 

 

Genes contain the genetic material to run cells, they are found in the DNA

Term

 

 

 

Where does an individual get it's genetic code?

Definition

 

 

The code on the DNA molecule is copied by the parent and passed on to the offspring during reproduction

Term

 

 

What causes growth in an individual?

Definition

 

 

Cell enlargement and cell division

Term

 

 

What is the difference between cell enlargement and cell division?

Definition

 

Cell enlargement is an increase in the size of the cells, cell division is an increase in the number of cells. 

Term

 

 

 

What do cells have to do with the development of an organism?

Definition

 

Repeated cell division as well as cell differenciation create development. 

 

Division allows growth, differenciation allows individual cells to specialize allowing change over the life cycle

 

 

Term

 

 

 

A catapiller turning into a butterfly is an example of 

 

A Growth 

B Development

Definition

 

 

B Development

Term

 

 

What do you call an organism that makes it's own food. 

Definition

 



Autotroph 

Term

 

 

How do phototrophs make food?

Definition

 

Phototrophs use solar energy as an energy source to make their food in a process called photosynthesis

Term

 

 

What do you call an organism that uses sulfer or another chemical to make it's energy? 

Definition

 

 

 

Chemoautotroph

Term

 

 

How do heterotrophs get energy?

Definition

 

 

By consuming energy rich molecules in other organisms. 

Hetero - other

hetero trophs take the energy from OTHER organisms 

Term

 

 

If an organism eats only plants what would it be called?

Definition

 

 

Herbivore 

Term

 

 

If an animal is an omnivore what does it eat? 

Definition

 

 

plants and animals

Term

Definition

 

 

Decomposers 

Term

 

 

What 2 things does an ecosystem involve?

Definition
