Flashcards in Chapter 4 Vocabulary Quiz Deck (20):
1

Binary fission

This process occurs in prokaryotes (bacteria and Archaea)It is a less complicated means by which the cells divide

2

Cancer

A tumor in which the cells begin dividing at an uncontrolled rate and can become invasive (affect the organism)

3

Cellular respiration

Glucose plus oxygen reacts to form carbon dioxide plus water

4

Chlorophyll

This is the main pigment used in photosynthesis that gives plants there green color. It is found within the chloroplasts.

5

Chromosome

In a eukaryotic cell it is one of the structures in the nucleus that are made up of DNA and protein. In a prokaryotic cell, it is the main ring of DNA.

6

Fermentation

The breakdown of food without the use of oxygen.

7

Melanoma

This is one type of deathly skin cancer. Wear that sunscreen!

8

Mitosis

This process occurs in eukaryotes. It is the process of cellular division that forms two new nuclei each of which has the same number of chromosomes.

9

Photosynthesis

Carbon dioxide plus water combines with light to form sugar and oxygen

10

ATP

Adenosine triphosphate is the molecule that is freed during the process of cellular respiration. Molecules of this supply readily available energy fuels cells activities such as growth

11

Cytokinesis

The division of the cytoplasm of a cell

12

Cell cycle

The lifecycle of a cell. It includes interfase, mitosis, and cytokinesis

13

Daughter cells

Cytokinesis, the cell divides resulting in these two identical cells

14

Cell plate

A major difference between cell division of animal and plant cells. Implant algae and fungi cell division, this forms between the two daughter cells during cytokinesis. This is where the new cell wall will form

15

Interphase

The longest portion of the cell cycle in which the cell replicates it's chromosomes they start to become sister chromatids) and organelles

16

Feedback switches

This term pertains to the proteins that control the go and stop of the cells lifecycle. If they are not functioning properly, rapid cell growth may occur (cancer)

17

Anaphase

This phase of mitosis in which the paired (or sister) chromatids are separated and pulled (by the centrioles) two opposite sides of the cell

18

Metaphase

A phase of mitosis in which the nuclear membrane dissolves in the sister chromatids a line in the middle of the cell (the cells equator).

19

Prophase

Phase of mitosis in which the chromosomes condense are thinking to become rodlike structures

20

Telophase

A phase of mitosis in which the nuclear membrane reforms around each set of chromosomes and the chromosomes do you can dance. The cell is just starting to pinch in two. Mitosis is now complete.
