Gen Bio Seb

Is the basic membrane bound unit that contains the fundamental molecules of life

Use basic microscope to look at thin slices of plant tissues - cork

Looked empty like monk's chamber

Was the first one to view pond water organism

He was the first one to observe blood and sperm cell w/ microscope

He introduced the first unicellular

The first unicellular organism

He is a german botanist and he concluded that all plants were made of cells

A german zoologist who concluded that animals were made if cells

A german physician who studied cell reproduction, he said that where a cell exists, there must have been a pre-existing cell

The 3 principles/components of cell thwory

are single cell that can perform all essential function that enables it to grow, survive, and reproduce

are more complex in structure and function but has the same mechanism on how they are able to live

Example of Unicellular Organism

Example of Multicellular Organism

Example of postulate 2

a cell consist of three parts

are seperated membraneous compartment inside the organ of a living organism

Function of Cell Organelles

It maintains the integrity of the cell and controls the passage of materials into and out of the cell

What is cell membrane made of?

It contains the cell'shereditary DNA and controls cellular activity

it is where the subunits of ribosomes are assembled

is a double membrane lipid layer enclosing the nucleus to protect DNA and nucleoplasm

is a permiable barriers that limits the entry of proteins and RNA but allow the free passage of water, ATP, ions and other small molecules

is a gel like substance made of dissolved protein and liquid

texture of cytoplasm

are little organs that are suspended in the cytoplasm of the cell

is the cellular site of respiration and production of ATP energy molecules that gives if the title of "powerhous of the cell"

are minute particles consisting of RNA and associated proteins

is the network of membraneous tubules that transport the materials needed by the cell

is studded with milllions of ribosomes and involved with production, folding, quality control and dispatch of other proteins

it is largely associated with lipid fat

is a cell organelle that helps process and package of proteins and lipids molecules

they are small, cylindrical cell organelles

are polymers of tubulin that forms the part of the cytoskeleton

is a thread like structure located inside the nucleus of animal and plant cells

is a membrane enclosed sac for storing essential materials

is an organelle found only in animal cells and involved with digestion and waste removal

is found exclusively in plant cell and contains the green chlorophyll pigments

is a membraneous compartment of flattened sac

made up of several stack

is highly concentrated fluid composed of enzymes, DNA and ribosomes

it is the non-living component, covering the outmost layer of a cell.

state that endosymbiosis became the means by which organelles such as mitochondria and chloroplasts within eukaryotic cell came about

considered to be the most important distinction among organisms

this cell contains membrane bound organelles

this cell does not contain membrane bound organelles

consist of sequencial phases of events wherein parent cell divides and replicate DNA to produce new daughter cells

Why do cell have to undergo cell cycle

the longest part of the cell's life cycle called the resting stage because the cell isn't dividing

cell mature and increase in size

sees the cell preparation for DNA replication

in this stage, the DNA is replicated and involved the actual replication of DNA materials which results to doubling of the chromosomal number

sees the cells continuing to grow in preperation for mitosis or meiosis

the cell examines the internal and external cues and decide whether or not to move forward with the division

g1 to s checkpoint

g2 checkpoint

is the chromosomes lined up in the middle?

is a process of cell division wherein the replicated traits of the chromosomes seperates into two new nuclei

is a special type of cell division that is exclusively for gametes

gametes

this is the starting stage of mitotic phase sees the chromatin of the nucleus condensing to form chromosomes

the stage wherein the nuclear envelope breaks down causing interaction of spindle and the chromosomes to form spindle fibers

the shortest phase of mitosis

the seperation of sister chromatids

sees the shortening of the microtubules of the kinetochores

is the division of the cytoplasma into two individual cell

Integral Proteins

integral membrane proteins can be classified:

it transport subtances in a unidirectional manner depending on the concentration gradient

these proteins acts as receptors for hormones, recognition center, and antigens

this are proteins that are present in red blood cells that acts as an antigens

occurs when particles movefrom an area of lower concentration toan area of lower concentration

if diffusion is taking place ona solvent across a semi-permeablemembrane, the transport is calledosmosis.

type of passivetransport that relies on carrier proteinsin order for the substances to movedown their concentration gradient

when the cell needsnutrients at a higher concentration thanit typically receives or at a faster ratethan what simple diffusion can offer

occurs wherein themolecule can bind to the surface of themembrane.
