Organelles Flashcards
Organelles
Small structures that help carry out the day-to-day operations of the cell
Ribosome
Organelles which participate in protein synthesis.
Mitochondrion
The power plants of the cell, are organelles that produce energy.
Lysosomes
Organelles that contain enzymes that aid in digestion
Cell areas
Three main areas:
The cell membrane
The cytoplasm
The nucleus
Cell(animal) types
Bone cell Muscle cell Nerve cell Cartilage cell Blood cell Small intestine cell
Cell wall
Found primarily in plant cells and is a rigid structure found outside the membrane.
Is made of cellulose.
Provides structural support, protections, and also acts as a filtering mechanism.
Cytoplasm
A jelly like substance
The material between the cell’s nucleus and the cell membrane
It fills the entire cell
It contains a large variety of organelles and nutrients
It stores nutrients
Nucleus
The cell’s command center
Contains the cell’s DNA, the genetic code.
Nuclear envelope
Also called nuclear membrane, found in both plant and animal cells.
Protects genetic material (DNA)
Protects the cell’s genetic material from the chemical reactions that take place outside the nucleus.
Contains many proteins that are used in organizing DNA and regulating genes
Chromosomes
Carries genetic information in the form of genes
A threadlike structure of nucleic acids and protein
Found I. The nucleus
Endoplasmic reticulum (ER)
In charge of manufacturing and packaging proteins
Works closely with the Golgi apparatus, ribosomes, and mRNA and tRNA
Many roles in the cell’s ER including calcium storage, protein synthesis and lipid metabolism
Ribosome
Synthesizes proteins or protein builders
Can be found floating within the cytoplasm or attached to the ER
Chloroplast
Captures the Sun’s energy and is the site where photosynthesis takes place. Which provides energy for growth, development, and repair.
Golgi Bodies ( Also called Golgi apparatus)
Modifies proteins and lipids
Process materials to be removed from the cell
Make secrete mucus
Packages products into vesicles for transport
