Reviewer Flashcards
One of the leading botanist of his time, he was able to compare different kinds of plants specimens under the microscope.
Robert Brown
He is a German botanist that concluded that all plant parts are made up of cells.
Matthias Schleiden
He is also a botanist and a close friend of Schleiden, stated that all animal tissues are composed of cells too.
Theodor Schwann
He considered that all cells comes from pre-existing cells.
Rudolf Virchow
This cell theory can be summed up into three (3) basic components.
- All living organisms are composed of one or more cells
- Cell is the basic unit of life
- All cells comes from pre-existing cells
What is a membrane system of interconnected tubules that serves as transport system of the cell.
Endoplasmic Reticulum (ER)
It consist of stacks or piles of flattened sacs called cisternae which are responsible for the packaging,sorting, and refining of the products that the cells are making.
Golgi bodies/Golgi Apparatus
What is one organelle that is larger in plants than in animal cells?
Vacuole
It serves as the main compartment for storing essential organic and inorganic compounds. It is also a disposal site for substances that are not needed by the cell or that could harm the cell.
Central vacuole or tonoplast
Is where organelles that are damaged are digested and turned into monomores, which will then be reused by the cell for the repair, maintenance, and creation of necessary cellular components.
Autophagy
This is only found in plant cells and other photosynthetic eukaryotic organisms.
Choloroplast
Which part contains a digestive enzyme that helps breaks down larger molecules in the cell?
Lysosome
What is the structure that separates the cell contents from its environment?
Cell Membrane
Which part of the cell serves as a venue for cellular respiration and is known as the powehouse of the cell?
Mitochondrion
Are the smallest functional unit that makes up all living things.
Cell
What is the structure that contains ions, substances, and suspended organelles?
Cytoplams
This cell are transformed cells that results from an uncontrolled cell division by overiding the checkpoints during cell division.
Cancer
Which part is responsible for the photosynthetic activities of a plant cell?
Chloroplast
It is a disorder that occurs when a cell has am incorrect number or set of choromosomes?
Aneuploidy
Two (2) common disorder under aneuploidy.
- Down Syndrome
- Turner Syndrome
This is a disorder that have extra chromosomes, giving the organism a total of 47 chromosomes.
Down Syndrome
This is a disorder that lack of one of its sec chromosomes, resulting in 45 chromosomes or 44 autosomes and X.
Turner Syndrome
It is a powerhouse of the cell where cellular respiration take place.
Mitochondrion
This can occur to avoid severe problems or threat to the cell or the organism in general.
Apoptosis or programmed cell death
Which part of the cell controls cell activities and transmit hereditary information?
Nucleus
The thousands of tiny empty chambers in cork are called cells.
Robert Hooke
Tiny living organism can be observed.
Anton van Leeuwenhoek
Cytoskeleton is composed of
Microfilaments,microtubules, intermediate filaments
Pairing of homologous chromosomes forming a tretrad
Synopsis
Is two chromosomes or four chromatids (sister and non-sister chromatids)
Tetrad
Chromatids of tretrad exchange parts.
Crossing over
The_____is where the DNA is located and controls the cell functions.
Nucleus
Which crossing over and exchange of genetic materia occur
Chiasmata
Variants of the some gene that occur on the same place on a chromosome
Allele
Are chromosomes pair (one from each parent) that are similar in length, gene position, and centromere location. The position of genes on each__________ is the same, however the genes may contain different alleles.
Homologous chromosomes
Males produce sperm throughout life, after the onset of puberty, about 1,500 sperm per second.
Spermatogenesis (sperm)
In females is probably complete either before or shortly after birth. During_______, three polar bodies develop as the mature ovum is generated.
Oogenesis (egg or ova)
It contain little cytoplasm and eventually degenerate.
Polar bodies
He reowned microbiologist, received his Doctor of Natural Sciences (magna cum laude, 2006) at the Technical University of Brounschweig in Germany.
Thomson Edison E. dela Cruz
He is multi-awarded Filipino inventor who snapped the top prize in the International Inventor’s Forum (IENA) in Germany for his latest product called DeBCC. This product is said to be an effective cure for skin cancer.
Ronaldo dela Cruz
Occurs only in GONADS (testes or ovaries)
Meosis
One of the most common diseases worlwide. It has different names depending on the tissue or organ that it affects.
Cancer
