A

Mitochondria

21
Q

The site of photosynthesis

A

Chloroplast

22
Q

Contain hydolytic enzymes that digestive materials entering the cell

A

Lysosomes

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
Q

Fluid-filled sacs which usually contain water, proteins, pigments or metabolic wastes

A

Vacuoles

26
Q

Threadlike structures composed mainly of DNA. This is the hereditary info of the cell

A

Chromosomes

27
Q

A tiny, grainy structure attached ti the Endoplasmic Reticulum. It serves as the protein factory of the cell

A

Ribosome

28
Q

This pressure is necessary for the cell to adjust to its needs and environment.

A

Turgor Pressure

29
Q

The process if combing administration acids to produce peptide chains to reconstruct proteins

A

Protein synthesis

30
Q

The process if combing administration acids to produce peptide chains to reconstruct proteins

A

Protein synthesis

31
Q

The process of cell reproduction following several stages to produce two daughter cells

A

Cell division

32
Q

Produces two genetically identical daughter cells from a single parent cell

A

Mitosis

33
Q

Four stages of mitosis

A

Prophase, metaphase, anaphase, telophase

34
Q

Produces cells that are genetically unique from a parent

A

Meiosis

35
Q

This type of cell division only occurs in plants animals and fungi

A

Meiosis

36
Q

A stage in mitosis where in dna replicates itself and forms messenger rna, transfer rna, and ribosomal rna

A

Interphase

37
Q

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

A

Prophase

38
Q

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

A

Metaphase

39
Q

This phase is characterized by the separation of sister chromatids into a single stranded chromosome. The chromosomes migrate to opposite poles of the cells

A

Anaphase

40
Q

During this phase, the chromosomes begin to uncoil and the nucleoli as well as the nuclear membrane reappear

A

Telophase

41
Q

This type of cell division consist of two successive cell divisions where chromosomes duplicate only once

A

Meiosis
