Zoology Lesson 2 CELL

Question 1

It is the outer covering of the cell

Answer 1

Cell Membrane

Question 2

It functions as the selective barrier that regulates the entrance and exit of substances into the cell

Answer 2

Cell Membrane

Question 3

The biggest part of the cell where organelles are found

Answer 3

Cytoplasm

Question 4

It is a continuous intercommunicating channel composed of membrane-enclosed sacs and tubules

Answer 4

The Endoplasmic Reticulum

Question 5

It is the more common type of endoplasmic reticulum, is defined by the presence of ribosomes.

Answer 5

Rough endoplasmic reticulum

Question 6

It is more tubular and non-granular due to the absence of ribosomes

Answer 6

Smooth endoplasmic reticulum

Question 7

It is the site of protein synthesis

Answer 7

Ribosomes

Question 8

It is responsible for sorting and packaging macromolecules for use within the cell or for exocytosis

Answer 8

The Golgi Apparatus

Question 9

It is the Powerhouse of the cell that varies in size, shape, and number, depending of cellular activity.

Answer 9

The Mitochondrion

Question 10

It is the site of Adenosine Triphosphate (ATP) synthesis and fatty acid oxidation.

Answer 10

The Mitochondrion

Question 11

It is a small membrane-bound
bodies that contain several hydrolytic enzymes, such as acid hydrolase, for intracellular digestion.

Answer 11

The lysosome

Question 12

It has a central role in cell division where it participates in the formation of the mitotic spindle. It is usually adjacent to the nucleus

Answer 12

Centriole

Question 13

It is where hereditary factors are stored. It is found in almost all cells

Answer 13

Nucleus

Question 14

It is a source of ribosomal (rRNA), messenger (mRNA), and transfer RNA (tRNA).

Answer 14

Nucleus

Question 15

It is the Nucleus’ two-layered outer limit separating it from the cytoplasm.

Answer 15

Nuclear Envelope

Question 16

It acts as a selective channel between the cytoplasm and the inside of the nucleus. It can be found on the Nuclear Envelope.

Answer 16

The Nuclear Pores

Question 17

It is also called as Karyoplasm

Answer 17

Nucleoplasm

Question 18

It is the fluid contained in the nucleus. Suspended to it is the spherical, non-membrane-bound nucleolus

Answer 18

The Nucleoplasm

Question 19

It is found inside the nucleus. It is made up of DNA and Proteins and forms chromosomes during cell division.

Answer 19

Chromatin

Question 20

What are the two types of Chromatin

Answer 20

euchromatin and heterochromatin

Question 21

It contains the genes inherited by the offspring from their parents.

Answer 21

Chromosome

Question 22

Name the four stages that the interphase is composed of.

Answer 22

• Gap 1 (G1)
• Synthesis (S)
• Gap 2 (G2)
• Mitosis (M)

Question 23

The phase of the cell cycle in which a cell copies its DNA to prepare for mitosis

Answer 23

Interphase

Question 24

It is the first phase of interphase that comes before the synthesis of DNA. The cell increases in mass and or size in preparation for cell division.

Answer 24

G1 Phase

Question 25

It is a crucial part of the interphase since this is when DNA is synthesized.

Answer 25

Synthesis Phase

Question 26

This is the phase that comes after DNA synthesis has occurred but before the start of mitosis involves the cell synthesizing proteins and continuing to increase in size, while simultaneously initiating the condensation of chromosomes and synthesizing the necessary proteins for the construction of the mitotic spindle.

Answer 26

G2 Phase

Question 27

It is the type of cell division that takes place in somatic or body cells

Answer 27

Mitosis

Question 28

The main purpose of this cell division is the production of more cells for growth, repair, and development.

Answer 28

Mitosis

Question 29

It produces two diploid somatic cells

Answer 29

Mitosis

Question 30

this is where the chromatin condenses into more discrete chromosomes.

Answer 30

Prophase

Question 31

This stage is where the nuclear envelope starts to disintegrate, and spindles form at opposite 'poles' of the cell.

Answer 31

Prophase

Question 32

This stage is where the spindle fibers fully develop.

Answer 32

Metaphase

Question 33

This stage is where the chromosomes align at the equatorial plate.

Answer 33

metaphase

Question 34

This stage is where the paired chromosomes separate and begin to move toward the opposite poles of the cell.

Answer 34

Anaphase

Question 35

At the end of this stage, each pole contains a complete set of chromosomes.

Answer 35

Anaphase

Question 36

This stage is where the chromosomes are confined into distinct new nuclei of the daughter cells.

Answer 36

Telophase

Question 37

This stage is where the cytoplasm splits in two and the cell divides.

Answer 37

Cytokinesis

Question 38

This is the cell division that takes place in sex cells or gametes

Answer 38

Meiosis

Question 39

It produces four genetically diverse haploid daughter cells from one diploid parent cell.

Answer 39

Meiosis
