CHARACTERISTICS OF LIVING THINGS
- Growth Development
- Reproduction
- Movement
- Metabolism
- Adaptability
- Homeostasis
Double layered called lipid bilayer
CELL MEMBRANE
contain protein molecules and carbohydrate molecules
CELL MEMBRANE
Separates cell from external
environment; controls passage of organic molecules, ions, water, oxygen and wastes into
and out of the cell.
CELL MEMBRANE
are multilayered
CELL WALLS
has cell junction called plasmodesma
CELL WALL
For protection, structural support and maintenance of cell shape
CELL WALL
is the material within a living cell,
excluding the cell nucleus
CYTOPLASM
Provides structure to cell; site of many metabolic reactions; medium in which organelles are found
CYTOPLASM
Convert energy from one chemical form to another
MITOCHONDRIA
It is enclosed by two membranes
MITOCHONDRIA
It is composed of two compartments,
the inter membrane space and the inner membrane
MITOCHONDRIA
ATP production or cellular respiration
MITOCHONDRIA
Produced by rough ER and golgi
apparatus
LYSOSOMES
Derived from two Greek words meaning “breakdown body”
LYSOSOMES
Digest cell’s food and wastes
LYSOSOMES
Digestion of macromolecules; recycling or worn out organelles
LYSOSOMES
Sac like structure that often store
materials such as water, salts, proteins and carbohydrates
VACUOLES
For storage and transport; digestive
function in plant cells
VACUOLES
Consists of flattened sacs that are not interconnected
GOLGI BODIES
It finishes, sorts and ships cell products
GOLGI BODIES
Modifies, sorts, tags, packages and
distributes lipids and proteins
GOLGI BODIES
Use energy from sunlight to make
energy rich food molecules in a process known as photosynthesis
CHLOROPLAST
Network of interconnected flattened sacs
ROUGH ENDOPLASMIC RETICULUM
Makes more membrane
ROUGH ENDOPLASMIC RETICULUM
Involved in the synthesis of proteins
ROUGH ENDOPLASMIC RETICULUM
Network of interconnected tubules that lack ribosomes
SMOOTH ENDOPLASMIC RETICULUM
Synthesize lipids, including fatty
acids,phospholipids and steroids
SMOOTH ENDOPLASMIC RETICULUM
produced proteins following
coded instructions that comes from the nucleus
RIBOSOMES
Cell’s genetic control center
NUCLEUS
Cell’s hereditary blueprint
NUCLEUS
Cell organelle that houses DNA and
directs synthesis of ribosomes and proteins
NUCLEUS
Consist parts of chromatin DNA
combined with RNA and proteins
NUCLEOLUS
It is where the components of ribosomes are made
NUCLEOLUS
Granular material consist of DNA bound to protein
CHROMATIN
A network of protein filament that helps the cell maintain its shape
CYTOSKELETON
It is also involved in many forms of cell movement
CYTOSKELETON
Maintains cells’ shape, secure organelles on specific positions, allows cytoplasm and vesicles to move within the cell, and enables
unicellular organisms to move independently
CYTOSKELETON
Oxidizes and breaks down fatty acids and amino acids and detoxifies poisons
PEROXISOMES
Unspecified role in cell division in animal cells; organizing center of microtubules in animal cells
CENTROSOMES
Cellular locomotion
FLAGELLA
Cellular locomotion, movement of
particles along extracellular surface of plasma membrane, and filtration
CILIA
