Goal 6 Review #2

1. A ______________________ is a type of cell that has a true nucleus.

Prokaryote

Eukaryote

Bacterium

Virus

prokaryotes and bacteria have primitive nuclei and virus are not even living

Explanation

prokaryotes and bacteria have primitive nuclei and virus are not even living

2. Mitosis generates

Daughter cells identical to the mother cell

Many reproductive cells

Diseased cells

Gametes

After mitosis is complete the daughter cells are exact copies of the mother cell. Gametes are sex cells and they are not exactly the same as the mother cell. Mitosis only generates one new daughter cell for every mother cell.

Explanation

After mitosis is complete the daughter cells are exact copies of the mother cell. Gametes are sex cells and they are not exactly the same as the mother cell. Mitosis only generates one new daughter cell for every mother cell.

3. What objecct is most similiar to the shape of a volvox?

Hotdog

Cell phone

Golf ball

Tree leaf

because both the volvox and a golf ball are spherical in shape

Explanation

because both the volvox and a golf ball are spherical in shape

4. Two structures found in plant cells that are not found in animal cells are the

Mitochondria and ribosomes

Cell wall and plastids

Cell membrane and centrioles

Nucleolus and endoplasmic reticulum

all others are found in both.

Explanation

all others are found in both.

5. Meiosis is a type of cell division that

Leads to genetic mutation

Creates somatic cells

Is necessary for sexual reproduction

Causes alleles to deform

Meiosis generates the sex cells so it is necessary for sexual reproduction.

Explanation

Meiosis generates the sex cells so it is necessary for sexual reproduction.

6. The necessary characteristics a substance must have in order to be classified as living are

A heart and lungs

The ability to nourish itself, grow, and reproduce

The ability to photosynthesize and to eliminate waste products

A true nucleus and nuclear membrane

to be living: have to be made of carbon, have to be able to respire (breathe), to take in nutrients, eliminate wastes, respond to stimuli, grow and reproduce.

Explanation

to be living: have to be made of carbon, have to be able to respire (breathe), to take in nutrients, eliminate wastes, respond to stimuli, grow and reproduce.

7. What structure do a volvox and a euglena use for movement?

Cilia

Pseudopods

Flagella

Eyespot

While the euglena does have an eyespot, it is used to detect light. Amoebas use pseudopods for movement. Cilia are used for movement by paramecium.

Explanation

While the euglena does have an eyespot, it is used to detect light. Amoebas use pseudopods for movement. Cilia are used for movement by paramecium.

8. Amoebas obtain food by wrapping the cell membrane around the food particle, creating a vesicle. The food is then brought into the cell. This process is called

Exocytosis

Endocyotosis

Osmosis

Photosynethesis

Photosynthesis is using the sun to make energy. Osmosis is water moving across a cell membrane. Exocyosis is particles leaving a cell using a vesicle. Endocyotosis is particles crossing a cell membrane using a vescile. Remember ENDO looks and sounds like IN.
