Flashcards in Cell Structure And Function Deck (33):
What are all the parts of the body made of?
Who observed a cork under a microscope and when?
Robert Hooke, in 1665.
What does Hooke saw and how did he called them?
Small rooms which he called cellulae.
Who saw living organisms in milk and pond water and how did he called them?
Anton Van Leeuwenhoek, animacules.
How many principles does the cell theory has?
Which are the three cell principles?
All living organisms are made of more that one cell.
Are the basic unit of organization of all living organisms.
Each cell came from another living cell. They pass copies of their genetic information during division.
They have various shapes and sizes, they differ in functions, they have all one thing in common. What are they?
What do every cells have in common?
The Plasma Membrane
What is the Plasma Membrane?
Is the cell structure responsible for homeostasis.
What is the selective permeability?
The ability of the PM to allow substances to pass through and to keep others out.
What is the cytoplasm?
Is the semifluid environment inside the cell.
It provides an anchor for the organelles using very thin fibers called microfilaments and microtubules, what is it?
What is the nucleus and what does it contain?
Like the “manager” of the cell, it contains DNA
What is DNA?
Is the information needed to make proteins for cell growth, function, and production.
Is the site where ribosomes are made?
What are ribosomes?
Help create proteins, are made of RNA.
What is Endoplasmic Reticulum?
The place where proteins and lipids are made.
How is the ER divided?
Into the Rough ER and the Smooth ER
What is the Rough ER?
Where ribosomes are attached.
What is the Smooth ER?
No ribosomes are attached there, lipids are made.
Where do proteins go after being created?
The Golgi Apparatus.
Where are proteins packaged?
Where do they go after being packed?
Wherever the cell needs it.
Are the place where food, waste, and other needed materials are stored:
Are vesicles that carry substances which digest old or excess organelles.
What are centrioles?
Groups of microtubules form them.
What is mitochondria?
Is the energy generator, produces ATP (Adesine Tri Phosphate)
Are structures connected to the outside of the PM in some prokaryotic and Eukaryotic cells.
Cilia and Flagella
What is cilia?
Are short, Look like hairs, Move in a “rowing” motion, Many per cell
What is flagella?
Are long, Look like tails, Move like a propeller, Only a few per cell.
A thick, rigid layer that surrounds a plant’s PM, what is it?
They are only found in plant cell, capture light and convert it into food(photosynthesis), energy from the sun is trapped in a pigment called chlorophyll, green.
