Instructions: Review the content in Chapter 3 of the textbook and prepare a table or diagram that compares the components and characteristics of prokaryotic and eukaryotic cells. Be sure to include both (1)similarities- characteristics in common and (2) differences- characteristics unique to each cell type.

My project:

Prokaryotic and Eukaryotic Cells

Similarities between Prokaryotic and Eukaryotic :

- Both are made of cells.

- Cell is covered by a lipid bilayer membrane

- Both reproduce and multiply for grows

- Their genetic material is either DND or RNA

Differences:

Prokaryote eukaryote

absent	nucleus	present
smaller	ribosome	larger
Fold and condense prokaryotic dna	dna	Wrap their dna around proteins called histones
absent	Membrane bound organelle	present
absent	chloroplast	present
Absent	mitochondria	present

My teachers notes :

Both cell types have cytoplasm.

Be specific and include a list of membrane bound organelles in eukaryotic cells.ï»¿ï»¿ï»¿ï»¿ï»¿ï»¿ï»¿ï»¿ï»¿ï»¿ï»¿ï»¿ï»¿ï»¿ï»¿ï»¿ï»¿

i need help with this homwork please choose the correct answers and just be claer to read and understand for the slect the apply qusestions too and it is important i realy need the right answers so please be claer not write randomly i really need the correct answers to study for my test so hop you can help me

membrane enclosed cell organelles

mitochondria

Question 5

Prokaryotes and eukaryotes both have which if the following cellular components. Click all that apply.

Question 6

I am made of one 60s and one 40s subunit, which organelle am I?

protein

lipid

bacterial ribosome

Question 9

The difference between the rough and smooth ER is

the rough produces lipids where as the smooth does not

the rough has many folds and convolutions where as the smooth does not

the rough has ribosome embedded and the smooth does not

the rough is closer to the cell membrane whereas the smooth is closer to the nucleus

Question 10

The site where many lipids, including cell membrane is produced.

Question 11

Name the organelle: In muscle cells in particular, I would increase in number and size in response to frequent exercise

In animal cells, glucose would be mobilized from its storage molecule (glycogen) in this part of the cell.

Question 13

Which of these is associated with the rough ER

production of carbohydrates

production of steroid hormones

production of ATP

production of proteins that are secreted from the cell

Question 14

Question 15

Which organelle is responsible for ATP production. Write one word in the singular as the answer.

Question 16

You inherit all of your mitochondria from your

father

half from your mother and half from your father

your siblings

mother

Question 17

An organelle that contains chlorophyll

Question 18

Microtubules have a variety of roles, which of the options below is NOT one of them?

separate chromosomes

cilia and flagellum movement

tracks for organelle movement

constrict the cell during cell division

Question 19

Made of tubulin subunits

microfilaments

microfilaments

microtubules

Intermediate filaments

Question 22

True

False

Question 23

connecting cells together

regulate the movement of substances into and out of the cell

helping cells divide into two cells

M2A1 Worksheet: Mitosis and Meiosis

A dog is a diploid organisms and has 39 pairs of chromosomes (2n = 78), where n = 39 chromosomes from each parent. Use this example to answer the following question regarding chromosomal number.

INTERPHASE

How many chromosomes are present in the somatic cell?

What do they look like?

What are they âdoingâ in G1 of this phase?

What is happening in the S phase?

What is happening in the G2 phase?

What follows G2 phase in a somatic cell?

What follows G2 phase in a gamete cell?

MITOSIS

Number of chromosomes in the parent cell.

Number of chromatids in the parent cell.

Number of chromosomes in the daughter cell.

Number of chromatids in the daughter cell.

How many daughter cells are produced?

Are the daughter cells haploid or diploid?

How many cell divisions take place?

In what type of cell does this division occur?

Meiosis 1:

Number of chromosomes in the parent cell.

Number of chromatids in the parent cell.

Number of chromosomes in each Meiosis I daughter cell.

Number of chromatids in each Meiosis I daughter cell.

Are the daughter cells haploid or diploid at the end of Meiosis 1?

Meiosis II:

Number of chromosomes in the âparentâ cell (which is a daughter cell from Meiosis I).

Number of chromatids in the âparentâ cell.

Number of chromosomes in each Meiosis II daughter cell.

Number of chromatids in each Meiosis II daughter cell.

Are the daughter cells haploid or diploid at the end of Meiosis II?

Which phase or phases of Meiosis account for the genetic variability among the daughter cells? Howâ¦ what happens in this phase to create the diversity?

Comparing Mitosis and Meiosisâ¦..

How many daughter cells result from Mitosis? Are they diploid or haploid?

How many daughter cells result from Meiosis? Are they diploid or Haploid?

Cell structures and function: Match each organelle to its function:
