Biology Unit Test Flashcards
Cell wall
surrounds and protects the cell
Nucleolus
contains the DNA
Centriole
Helps pull chromosomes to opposite poles of the cell
Cell membrane
surrounds and protects the cell
Centromere
where the spindle fibers attach
Cardiac muscle
involuntary striated muscle tissue found in the heart, is responsible for the ability of the heart to pump blood
Ground tissue
a plant tissue other than those of the dermal tissues and the vascular tissues, arises from the ground meristem, fills in the soft parts of the plants
Interphase
the first and longest phase in a cell’s life
Epiglottis
a small, movable “lid” above the larynx that prevents food and drink from entering your windpipe
Stamen
the pollen-producing part of a flower
Stem cells
the body’s raw materials, cells from which all other cells with specialized functions are generated, under the right conditions stem cells divide to form more cells called daughter cells
Gall bladder
a storage pouch for bile, a liquid that aids digestion
Crop
a thin-walled expanded portion of the alimentary tract used for the storage of food prior to digestion
Metaphase
the middle of a cell’s life cycle, beginning of mitosis, everything lined up in the middle
Esophagus
the muscular tube that carries food and liquids from your mouth to the stomach
Cell plate
the structure found inside the dividing cells of plants
Anaphase
the second phase of mitosis where sister chromatids have split up
Digestion
the complex process of turning the food you eat into nutrients
Chloroplast
use energy from the sun to make food
Respiratory
the network of organs and tissues that help you breathe.
Centrosome
a cellular structure involved in the process of cell division, it duplicates and the two centrosomes move to opposite ends of the animal cell
Nervous
coordinates the body’s actions and sensory information by transmitting signals to and from different parts
Connective tissue
tissue that supports, protects and gives structure to other tissues and organs in the body
Phloem
vascular tissue that transports carbon (photosynthates) from the leaves to basal parts of the plant.
