1.2 Eukaryotic Cells Flashcards
A rigid structure that surrounds the cell membrane and provides support to the cell.
Cell Wall
A cell organelle composed of RNA and protein; the site of protein synthesis.
Ribosome
A network of membranous tubules within the cytoplasm of a eukaryotic cell, continuous with the nuclear membrane. It usually has ribosomes attached and is involved in protein and lipid synthesis.
Endoplasmic Reticulum
An organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. It has a double membrane, the inner layer being folded inward to form layers (cristae).
Mitochondrion
Cell organelle that helps make and package materials to be transported out of the cell.
Golgi Complex
A fluid- or air-filled cavity or sac, in particular.
Vesicle
A cell organelle that contains digestive enzymes.
Lysosome
Cell is a peer-reviewed scientific journal publishing research papers across a broad range of disciplines within the life sciences.
Cell
Cellulose is an organic compound with the formula n, a polysaccharide consisting of a linear chain of several hundred to many thousands of β linked D-glucose units.
Cellulose
A fibrous substance consisting of polysaccharides and forming the major constituent in the exoskeleton of arthropods and the cell walls of fungi.
Chitin
The semipermeable membrane surrounding the cytoplasm of a cell.
Cell Membrane
The cytoskeleton of a cell is made up of microtubules, actin filaments, and intermediate filaments. These structures give the cell its shape and help organize the cell’s parts. In addition, they provide a basis for movement and cell division.
Cytoskeleton
The central and most important part of an object, movement, or group, forming the basis for its activity and growth.
Nucleus
A small dense spherical structure in the nucleus of a cell during interphase.
Nuceolus
The essential amino acids are arginine (required for the young, but not for adults), histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. These amino acids are required in the diet.
Amino Acids
In biology, lipids comprise a group of naturally occurring molecules that include fats, waxes, sterols, fat-soluble vitamins, monoglycerides, diglycerides, triglycerides, phospholipids, and others.
Lipids
A lipid containing a phosphate group in its molecule, e.g., lecithin.
Phospholipid
Tending to repel or fail to mix with water.
Hydrophobic
Having a tendency to mix with, dissolve in, or be wetted by water.
Hydrophilic
The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
Photosynthesis
Chlorophyll is any of several closely related green pigments found in cyanobacteria and the chloroplasts of algae and plants. Its name is derived from the Greek words χλωρός, chloros and φύλλον, phyllon.
Chlorophyll
A space or vesicle within the cytoplasm of a cell, enclosed by a membrane and typically containing fluid.
Vacuole
The organelle that uses the energy of sunlight to make food.
Chloroplast
