Modified Cells Flashcards
_________ are resistant to extreme heat, extreme cold, dehydration, and large amount of ultraviolet radiation
Endospores
______ are highly resistant to many chemicals, including most disinfectants and can survive for many years in soil and other inanimate objects
Spores
What is the main difference between spores and endospores (Wala ni siya na explain sa mods gid pero maka help ni clear up sang confusion)
spore is an active reproductive structure mainly produced by plants and fungi whereas endospore is a dormant, non-reproductive structure of bacteria
Hemoglobin-containing, disc-shaped that transports oxygen to the body cells.
Enucleated red blood cell
Hair-like structure made of proteins that enable bacteria to adhere to tissue surfaces.
Pili
Cell membrane extensions of an epithelial cell that increase the surface area of cells.
Microvilli
Thin neuron branch that receives neural messages from other neurons and conduct the impulses to the cell body.
Dendrites
Help in the survival of the organisms during adverse environmental conditions (heat, high pressure, and stress).
spores
Filaments of protein that permit the muscle to contract and elongate for organism activity.
Actin and Myosin
A neuron extension that transmits messages away from the cell body to other neurons and muscles
Axons
Tiny hair-like structures that increase the area available for water absorption and that of minerals and other nutrients
Root hairs
Hair-like projections that can also move an egg cell through the female reproductive tract.
Cilia
Whip-like structure that aid for the propulsion of single cells (facilitates sperm motility)
Flagella
Thousands of microvilli form a structure called the ___________ that is found on the apical surface of some epithelial cells, like those in small intestine.
brush border
The reason why enucleated red blood cell can bend and fit through narrower capillaries more than a nucleated red blood cell
because it lacks a nucleus
