Science Vocabulary Words (Organelles) Flashcards
the outer layer of a cell that’s rigid, strong, and stiff, and is made of cellulose
support (grow tall)
protection
allows H2O, O2, CO2 to pass into and out of cell
cell wall
this is selectively permeable. When this is in a plant cell, it’s on the inside of the cell wall but, if it’s in an animal, it’s on the outer layer of the cell; cholesterol
support
protection
controls movement of materials in/out of cell
barrier between cell and its environment
maintains homeostasis
cell membraine
this is large, and generally oval
controls cell activities
key organelle which has the genetic material and is
involved in multiplication of cell, growth and maintenance
of cells.
nucleus
the powerhouse of the cell that’s bean-shaped
breaks down sugar molecules into energy
site of aerobic cellular respiration
mitochondria
found inside a cell’s nucleus, there might be multiple of them, and it disappears during a cell division
Make ribosomes, contains building blocks or mRNA,
tRNA, rRNA
nucleolus
surrounds the nucleus, and is selectively permeable
Controls movement of materials in/out of nucleus
nuclear membrane
a jelly like material that’s clear, and thick, and all Organelles are found inside this substance. it also contains cytoskelon fibers
supports /protects cell organelles
cytoplasm
the network of tubes or membranes that has no ribosome, but has ribosome attached to it
carries materials through cell
Synthesis of fats/lipids
Ribosomes synthesis proteins for export
endoplasmic reticulum
small bodies free or attached to E.R., and is made of rRNA and protein
synthesizes proteins
ribosome
the vacuoles or sac-like structures that occupy a considerable amount of cytoplasm, and are stacks of flattened sacs
to modify and package proteins for export
have cis and trans face
Golgi/golgi bodies/golgi apparatus
fluid-filled sacs
Vacuoles are pouches in the cell that store materials such
as water, salts, proteins, and carbohydrates, waste products
and toxic waste..
store food, water, waste (plants need to store large amounts
of food)
vacuole
green, oval usually containing chlorophyll
uses energy from sun to make food for the plant
(photosynthesis)
chloroplast
