Bimonthly FEBRUARYYYY Flashcards
What did Hooke
In 1665 Hooke was the first to identify cells, and he named them.
What are The major principles of the cell theory?
• All organisms are made of cells.
• All existing cells are produced by other living cells.
• The cell is the most basic unit of life.
What did LeeUwenHOeK?
In 1674 Because he made better lenses, Leeuwenhoek observed cells in greater detail.
What did Schleiden
In 1838 Schleiden was the first to note that plants are made of cells.
What did SCHwAnn
In 1839 Schwann con- cluded that all living things are made of cells.
What did Virchow
In 1855 Virchow proposed that all cells come from other cells.
is a jellylike substance that contains dissolved molecular building blocks—such as proteins, nucleic acids, minerals, and ions.
Cytoplasm
are structures specialized to per- form distinct processes within a cell.
Organelles
do not have a nucleus or other membrane-bound organelles.
prokaryotic cells
have a nucleus and other membrane- bound organelles.
eukaryotic cells
which is a network of proteins that is constantly changing to meet the needs of a cell.
Cytoskeleton
is the storehouse for most of the genetic infor- mation, or DNA (deoxyribonucleic acid), in your cells.
Nucleus
is an interconnected network of thin folded membranes.
The endoplasmic reticulum
tiny organelles that link amino acids together to form proteins.
Ribosomes
consists of closely layered stacks of membrane-enclosed spaces that process, sort, and deliver proteins.
Golgi Apparatus
are a general name used to describe small membrane-bound sacs that divide some materials from the rest of the cytoplasm and transport these materials from place to place within the cell.
Vesicle
supply energy to the cell.
Mitochondria
is a fluid-filled sac used for the storage of materials needed by a cell.
Vacuole
are membrane-bound organelles that contain enzymes.
Lysosomes
are cylinder-shaped organelles made of short microtubules arranged in a circle.
Centrioles
which is a rigid layer that gives protection, support, and shape to the cell.
Cell wall
is a dense region where tiny organelles essential for making proteins are assembled.
Nucleolus
is a structure unique to plant cells.
CENTRAL VACUOLE
is a eukaryote that is not an animal, a plant, or a fungus.
Protists
What are the three types of protists
Animal-like protists
Plantlike protists
Funguslike protists
are het- erotrophs—organisms that consume other organisms.
Animal like protists
make their own food by photosynthesis just as plants do.
Plant like protists
decompose dead organisms.
Funguslike protists
tough polysaccharide that is also found
in the shells of insects and their close relatives.
Chitin
long strands
Hyphae
What are the three part is f the fungi
Hyphae,mycelium and Fruiting body
The function of fungi is..
Decompose
Fungi are
Heterotrophs that absorbs their food
is the real fungi inside of the earth.
Mycelium
Is just the reproductory system.
The fruiting body
are the smallest and simplest group of fungi and are aquatic and have flagellated spores.
Primitive Fungi
form a reproductive sac,or ascus.
Sac Fungi
are often found on spoiled food.
Bread Molds
have fruiting bodies which are club-shaped.
Club fungi
Fungi reproduce..
Sexually and Asexually
Yeasts reproduce asexually through
budding
Yeasts form asci during
sexual reproduction.
are mutualistic partnerships between fungi and the roots of certain plants.
Mycorrhizae
is a mutualistic relationship between a fungus and algae or photosynthetic bacteria.
Lichen
Fungi and bacteria are the main .
decomposers in any ecosystem
Like bacteria, some fungi can be
pathogenic, or disease-causing.
The overuse and incorrect use of antibiotics is one ex- ample of
how humans allow pathogens an opportunity to cause infection.
is a symbiotic relationship in which both organisms benefit.
Mutualism
What are the three types that fungi can mutualism
Lichens, Mycorrhizae, and insects
