17
Q

A double layer of lipids that surrounds the cell. It controls what moves into and out of the cell

A

Cell membrane

18
Q

Contains the genetic info

19
Q

A semi fluid liquid that fills the cell and holds the components of a cell

20
Q

The powerhouse of the cell. The site where energy (ATP) is obtained from food consumed

A

Mitochondria

21
Q

The site of photosynthesis

A

Chloroplast

22
Q

Contain hydolytic enzymes that digestive materials entering the cell

23
Q

Does not have ribosome attached and is the transpo system of the cell

A

Smooth Endoplasmic Reticulum

24
Q

Has ribosome attached and also carries our cell transi, but mainly of necessary protein materials needed

A

Rough Endoplasmic Reticulum

25
Fluid-filled sacs which usually contain water, proteins, pigments or metabolic wastes
Vacuoles
26
Threadlike structures composed mainly of DNA. This is the hereditary info of the cell
Chromosomes
27
A tiny, grainy structure attached ti the Endoplasmic Reticulum. It serves as the protein factory of the cell
Ribosome
28
This pressure is necessary for the cell to adjust to its needs and environment.
Turgor Pressure
29
The process if combing administration acids to produce peptide chains to reconstruct proteins
Protein synthesis
30
The process if combing administration acids to produce peptide chains to reconstruct proteins
Protein synthesis
31
The process of cell reproduction following several stages to produce two daughter cells
Cell division
32
Produces two genetically identical daughter cells from a single parent cell
Mitosis
33
Four stages of mitosis
Prophase, metaphase, anaphase, telophase
34
Produces cells that are genetically unique from a parent
Meiosis
35
This type of cell division only occurs in plants animals and fungi
Meiosis
36
A stage in mitosis where in dna replicates itself and forms messenger rna, transfer rna, and ribosomal rna
Interphase
37
During this stage in mitosis, chromatids shorten and thicken. The nucleoli disappear and the nuclear membrane breaks down and disappears as well. Spindle fiber begins to form
Prophase
38
During the space in mitosis each chromosome moves to the equator or middle of the spindle. The paired chromosomes attached to the spindle at the centromere
Metaphase
39
This phase is characterized by the separation of sister chromatids into a single stranded chromosome. The chromosomes migrate to opposite poles of the cells
Anaphase
40
During this phase, the chromosomes begin to uncoil and the nucleoli as well as the nuclear membrane reappear
Telophase
41
This type of cell division consist of two successive cell divisions where chromosomes duplicate only once
Meiosis
