1

The study of microanatomy of cells, tissues and organs

Histology

2

Units of measurements in microscopy

Angstrom
Micrometer
Micron

3

The father of Microscopic Anatomy and Histology

Marcello Malphigi

4

He discovered the microscope

Leeuwen Hoek

5

It is the basic structural unit of life

Cell

6

Differences between prokaryotic and Eukaryotic

Prokaryotic- no true nucleus, found in bacteria, cell membrane not defined, Binary fission and contains one copy of each gene- Haploid

Eukaryotic- True nucleus, found in Animal, Plant, Fungi, and unicellular organisms, defined cell membrane, undergoes Meiosis and Mitosis

7

First growth phase of the cell

G1 Phase

8

Dna synthesis where TWO sister chromatids are produced

S- phase

9

Second growth phase of the cell

G2 Phase

10

preparation or resting phase for MITOSIS

Interphase

11

Majority of life cells are in what phase?

Interphase

12

Phase where in chromosome condense and become visible "PAIR UP"

Prophase

13

Phase where mitotic spindle apparatus forms at the opposite poles of the cell.

Prophase

14

Mitotic spindle is made up of?

MICROTUBULE

15

Chromosome checkpoint

Metaphase

16

Phase where chromosome align at the equatrial plate and held in place by microtubules.

Metaphase

17

Phase where sister chromatids and centromere separate and move toward the oppsite poles

Anaphase

18

phase when daughter chromosomes arrive at the poles and microtubules disappear.

Telophase

19

Phase where the last stage of Mitosis when there is Cleavage furrow

Cytokinesis

20

Chromosome with shorter arm

P- arm

21

Chromosome with longer arm

Q-arm

22

Pat of a cell that is made up of semi-permeable phospholipid bilayer

Cell membrane

23

Cell membrane is also known as

Plasma membrane / Cytoplasmic membrane

24

The major constituents of cell membrane

Lipid and Proteins

25

The major Non-Phospholipid constituent of cell membrane

Cholesterol

26

The fluid found inside the cell where organelles are suspended

Cytoplasm

27

These are tiny cellular structures that perform specific functions within a cell and are embedded within the cytoplasm

Organelle

28

A double membrane organelle containing the genetic information carried by DNA

Nucleus

29

Contains RNA for ribosomal synthesis (rRNA)

Nucleolus

30

a double membrane orhganelle that is the powerhouse of the cell

Mitochondira
