Basic unit of life

Scientific theory which descrthe properties of cells

The Unifying Principle of Biology

The development of refinement of magnifying lenses and light microscopes made the observation and description of microscopic organisms and living cells possible

English Scientist who sliced a cork(oak)

Coined the term cell(from greek word “cella”)

Pertaining to room like structures

Produced the first microscope

First creator of a compound microscope

He discovered animalcules in pond water using his improved microscope

Animalcules are known as ___ today

Discovered the presence of nucleus within cells

Discovered that cells contain a sarcote, a fluid life substance

Obsolete term for protoplasm

Coined the term protoplasm for the fluid and substance of the cell

Established the protoplasm concept

German Botanist who examined and discovered that plant parts are made up of basic structure of cells

A german zoologist who examined and discovered tha animal parts are made up of cells

A german physician, stated that all living cells arise from pre-existing cells

3 Postulates of Cell theory

A.K.A Plasma membrane

A semi-permeable outer layer of the living crll which controls the passage of material within the surrounding

The entire region between the plasma membrane and nuclear envelop

Membrane-bound “little organs” that are suspended in the cytoplasm of the cell

Aqueous component of the cytoplasm wall

The stored nutrients, secretory products, and pigment granules that are produced by the organelles

The hereditary material of all organisms

The cellular organelles responsible for protein synthesis

Common components of all cells

The outer layer of the cell made up of a phospholipid bilayer

Outermost structure of plant cells which consists of cellulose and other substances

Gives rigidity and strength to the plant cells

The prominent and central part of the cell

The cell organelle that houses the DNA

A double membrane structure that constitutes the outermost portion of the nucleus

It is punctuated with pores that control the passage of materials between the nucleoplasm and cytoplasm

Semi-solid fluid inside the nucleus, where we can find the chromatin and the nucleolus

A dark staining region within the nucleud that aggregates the ribosomal RNA with associated proteins to assemble the ribosomal subunits

Powerhouse of the cell

Carry out oxidation reactiosn that break down fatty acids and amino acids

Acts as a digestive structure that stores food

Stores waste products to be eleased

Taking up space and pushing other organelles closer to the plasma membrane and gicing plant cell its shape

Source of microtubes in animal cells

“Suicidal bag” of the cell

Responsible for the digestion if macromolecules and recycling of worn-out organelles

Are membrane-bound organelles found in plants that contain pigment

Green pigment

Red Pigment

White or colorless

Oily Pigments

An extensive network of membrane-enclosed spaces in the cytoplasm

Has attached ribosomes to its cytoplasmic surface

It is where synthesized proteins are destined to be secreted out of the cell

Has no attched ribosomes to its cytoplasmic surface

A collection of flat sacs, usually located in the cell between the ER and the plasma membrane

Modifies and repackages the newly made proteins by adding chemical groups which will be delivered to other detinations in the cell

A network of protein fibers that is mad eup of mucrofilaments, intermediate filaments and microtubules

Exemplified only by the uni-cellular bacteri

Considered as primitive and do not possess a nucleus, and other membrane-bound organelles

Consists of the unicellular protists and fungi ad well the multi-cellular plants and animals

Posses “true nucleus” and has other membrane-bound organelles that allow compartmentalization of functions

Additional features to the cel’s body that evolve as they adapt to external pressures for efficient functioning

What are the 3 types of cell surface modifications

Long, stilized microtubules which is the central foundation kf cilia and flagella

Barrel-like microtublues structures

Tip of the cell surface

Plural of Cilia

It is under Apical and is often found in eukaryotic cells

Hair like structures

Usually present on a cell’s surface on large numbers

Used to move entire cells or sweep off the substances

Usually occur one per cell

Detect mechanical change

detect chemicals

detect light

organelle found in both prokaryotic and eukaryotic cells

whip-like structure
