Cell Theory Flashcards
Who created the first compound microscope?
Zacharias Janssen
Who coined the term “cells” ?
Robert Hooke duh cno pa ba
What did Robert Hooke observe under the microscope?
Dead Oak tree bark, or cork cells
How did Robert Hooke coin the term “cells”?
It reminded him of the cells of monks (“yung mga oblaks” – sir jeniel) in a monastery
A botanist who stated that plants are made up of cells
Matthias Jakob Schleiden
A physiologist and physician who stated that animals are made up of cells
Theodor Schwann
The father of microbiology
Antonie Van Leeuwenhoek
What did Leeuwenhoek call the protozoans he observed?
Animalcules
Which German physician stated that cells come from pre-existing cells through cell division?
Rudolf Virchow
What is the first postulate of the cell theory?
All living things are made up of cells.
What is the second postulate of the cell theory?
Cells are the smallest functional and structural unit of life.
What is the third postulate of the cell theory?
Cells come from pre-existing cells
What is the fourth postulate of the cell theory?
Cells contain genetic material that is passed on from cell to cell during cell division.
What is the 5th postulate of the cell theory?
All cells are basically the same in structure and chemical composition.
What is the 6th postulate of the cell theory?
Energy flow or biochemical processes occur inside of the cell.
These are membrane bound structures found within the cell which performs specific functions that are vital to cellular life.
Organelles
The word “Organelle” is latin for?
Little Organs (hahaha ang cute)
This is a thin, double layer of fats and proteins. It regulates the passage of materials in and out of the cell.
Cell Membrane
This is a rigid membrane only found in plant cells, which provides structure, support, and protection for plant cells.
Cell Wall
Cell walls are mostly made up of?
Cellulose
What are the 3 parts of the nucleus?
Nucleolus, Nucleoplasm, Nuclear pore
It is the control center of the cell
Nucleus
It is the part of the nucleus that synthesizes ribosomal RNA
Nucleolus
The part of the nucleus that regulates the synthesis of ribosomes
Nucleolus
______ is a complex molecule made up of protein + rRNA
Ribosomes
It is the powerhouse of the cell hhahahaahahaha pag mali ka pa dito babalik kita sa grade 2`
Mitochondria >_<
What chemical does the mitochondria create?
Adenosine Triphosphate (ATP)
It is a double-membraned organelle which contains its own DNA.
Mitochondria
What are the two types of endoplasmic reticulum?
Rough ER, Smooth ER
Which ER contains ribosomes?
Rough ER
What does the Smooth ER synthesize?
Steroids, Lipids, Carbohydrates
What does the Rough ER do?
It synthesizes proteins
How does the rER send proteins to the Golgi apparatus?
Through vesicles
It sorts, tags, packages, and distribute lipids and proteins.
Golgi body/ Golgi Apparatus
It breaks down worn-out or damaged organelles, contains digestive enzymes, and induces apoptosis.
Lysosomes
It is a disc-shaped organelle unique to plant cells, which contains the pigment chlorophyll.
Chloroplast
It is the site of photosynthesis
Chloroplast
The vacuole is more abundant in ______ cells.
Plant cells
Water is stored inside of this organelle, it also stores waste materials.
Vacuole
It is a network of protein filaments or fibers.
Cytoskeleton
Name the 3 types of cytoskeleton
Microtubules, Microfilaments, Intermediate filaments
It is a jelly-like fluid that fills each cell and is enclosed by the membrane.
Cytoplasm
