1
New cards

Scientific Method

A systematic process for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.

2
New cards

Problem Statement

A clear, concise description of the issue that needs to be addressed.

3
New cards

Literature Review

An assessment of existing research relevant to the problem being studied.

4
New cards

Hypothesis Formulation

The process of creating a testable statement predicting the outcome of an experiment.

5
New cards

Experimentation

The act of conducting tests to validate or invalidate a hypothesis.

6
New cards

Data Collection & Analysis

Gathering and interpreting information from experiments to draw conclusions.

7
New cards

Conclusion

The final decision made based on the analysis of data, either accepting or rejecting the hypothesis.

8
New cards

Null Hypothesis (Ho)

A statement that there is no effect or no difference, used as a default position in hypothesis testing.

9
New cards

Alternative Hypothesis (Ha)

A statement that indicates the presence of an effect or difference, opposing the null hypothesis.

10
New cards

Accept

To agree with the alternative hypothesis based on experimental evidence.

11
New cards

Reject

To disagree with the null hypothesis based on experimental evidence.

12
New cards

Antibacterial

A substance that inhibits the growth of bacteria.

13
New cards

Microliter (ml)

A unit of volume equal to one-millionth of a liter.

14
New cards

Objective Lens

A lens in a microscope that gathers light from the specimen and focuses it to create an image.

15
New cards

Total Magnification

The product of the magnification of the objective lens and the eyepiece lens in a microscope.

16
New cards

Cell Theory

A fundamental concept in biology stating that all living things are composed of cells, the cell is the basic unit of life, and all cells arise from pre-existing cells.

17
New cards

Cell Membrane

The outer covering of a cell that supports and protects it, also known as the plasma membrane.

18
New cards

Cytoplasm

The thick, clear liquid substance within a cell where organelles are suspended.

19
New cards

Nucleus

The control center of a cell that contains DNA and regulates cell activities.

20
New cards

Endoplasmic Reticulum (ER)

An organelle that transports substances and plays a role in metabolism, with rough and smooth types.

21
New cards

Golgi Apparatus

The cell's "post office," responsible for packaging and distributing molecules processed by the ER.

22
New cards

Mitochondria

Organelles known as the powerhouse of the cell, responsible for producing ATP through cellular respiration.

23
New cards

Lysosomes

Organelles that act as recycling centers, digesting old or foreign cells and substances.

24
New cards

Ribosomes

Structures that synthesize proteins using genetic material from the cell.

25
New cards

Cell Wall

A rigid outer layer found only in plant cells that provides protection and structure.

26
New cards

Chloroplast

Organelles in plant cells responsible for photosynthesis, containing chlorophyll.

27
New cards

Vacuoles

Storage organelles in cells that hold food, water, and waste.

28
New cards

Eukaryotic Cells

Cells with a nucleus, such as animal cells.

29
New cards

Prokaryotic Cells

Cells without a nucleus, such as bacteria.

30
New cards

Mitosis

A process of cell division that results in two identical daughter cells.

31
New cards

Meiosis

A type of cell division that produces four haploid cells, such as gametes.

32
New cards

Cell Membrane Structure

Composed of a phospholipid bilayer that is semi-permeable.

33
New cards

Fluid Mosaic Model

A model describing the structure of cell membranes as a mosaic of various proteins floating in or on the fluid lipid bilayer.

34
New cards

Homeostasis

The process of maintaining a stable internal environment within a cell.

35
New cards

Diffusion

The movement of molecules from an area of higher concentration to an area of lower concentration.

36
New cards

Active Transport

The movement of molecules across a membrane using energy, typically against a concentration gradient.

37
New cards

Passive Transport

The movement of molecules across a membrane without the use of energy.

38
New cards

Osmosis

The diffusion of water across a selectively permeable membrane.

39
New cards

Hypertonic Solution

A solution with a higher concentration of solute compared to another solution.

40
New cards

Hypotonic Solution

A solution with a lower concentration of solute compared to another solution.

41
New cards

Isotonic Solution

A solution with equal concentrations of solute compared to another solution.

42
New cards

Phagocytosis

A type of bulk transport where a cell engulfs solid particles.

43
New cards

Pinocytosis

A type of bulk transport where a cell takes in liquid from the surrounding environment.

44
New cards

Exocytosis

The process of expelling materials from a cell by vesicles fusing with the plasma membrane.
