Introduction To Cell Biology
Rigidity in a new location, change the shape of the cell, or even cause the whole cell or some of its parts to move. Crawling... Movements of a protist ___ and movement of some of our white blood cells
Amoeba
A versatile compartment that can account for more than half the volume of a mature plant cell. Stores organic nutrients, such as proteins stockpiled in ___ seed cells.
Central vacuole
Which are unique to the photosynthetic cells of plants and algae, are the organelles that perform photosynthesis. Absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant.
Chloroplasts
Within the nucleus, long DNA molecules and associated proteins form fibers called
Chromatin
are thread-like structures located inside the nucleus of animal and plant cells. Is made of protein and a single molecule of protein and acid (DNA).
Chromosome
Are generally shorter and more numerous than flagella and move in a coordinated back-and-forth motion, like the rhythmic oars of a crew team.
Cillia
The inner membrane of the envelope has numerous infoldings called
Cristae
The region of the cell outside the nucleus and within the plasma membrane is called...
Cytoplasm
of a Eukaryotic cell is partitioned by organelle membranes are physically connected, and others are linked by vesicles
Cytoplasm
Cells have an infrastructure called_____. Network of protein fibers extending throughout the cytoplasm. Both skeleton and "muscles" for the cell, functioning in support and movement.
Cytoskeleton
is the part of the cytoplasm that is not held by any of the organelles in the cell. On the other hand, cytoplasm is the part of the cell which is contained within the entire cell membrane.
Cytosol
Other ribosomes are attached to the outside if the nucleus or an organelle. 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. Organelle responsible for the Biosynthesis of protein that are destined for secretion by the cell is the
Endoplasmic Reticulum
Propel cells with an undulating, whiplike motion. They often occur singly, such as in human sperm cells, but may also appear in groups on the outer surface of protists.
Eukaryotic Flagella
Animal cells lack a cell wall, but most animal cells secrete a sticky coat called
Extracellular Matrix
Microtubules are arranged into structures called ___ extensions from a cell that aid in movement
Flagella, and Cillia
Working in close partnership with the ER, the ____ an organelle named for its dicoverer. Detailing facility that receives shipments of newly manufactured proteins. Proteins within a vesicle are usually modified by enzymes during their transit from receiving to the shipping side of the.. Warehouse
Golgi Apparatus
Enclosed sac of digestive enzymes found in Animal cells. Break down large molecules such as proteins, polysaccharides, fats and nucleic acids.
Lysosomes
One important type of fiber forms ___, hollow tubes of proteins.
Microtubules
Energy is harvested from sugars and transformed into another form of chemical energy called ATP, cells use molecules of ATP as a direct energy source.
Mitochondria
Does animal cells have Central Vacuole, Cell Wall, Chloroplast??
NO
Does plant have Centriole, and Lysosome?
NO
DNA is inside the
Nucleus
What is the Control center of the factory cell?
Nucleus
Two distinct regions a "head" with a negatively charged Phosphate group and two nonpolar fatty acid "tails". What is the major lipid found in membranes.
Phospholipid
Group together to form a two-layer sheet. Will associate proteins..
Phospholipid Bilayer
A microscopic membrane of lipids and proteins that forms the external boundary of the cytoplasm of a cell or encloses a vacuole, and that regulates the passage of molecules in and out of the cytoplasm.
Plasma Membrane
Surrounding their plasma membranes, plant cells have a cell wall made from cellulose fibers, which are long chains of
Polysaccharide
__ can be likened to workers on the factory floor because they do most of the actual work of the cell.
Proteins
Are responsible for protein synthesis. Are made in the nucleus and then transported through the pores of the nuclear envelope into the cyoplasm
Ribosomes
Phospholipids made by enzymes of the_____. Grows, and portions of it can bubble off and be transferred to other parts of the cell. Cells that secrete a lot of protein
Rough ER
This system includes the nuclear envelope, protein movement through the endomembrane would be
Rough Endoplasmic reticulum, Golgi Apparatus and Plasma Membrane
It makes fats. One is the synthesis of lipids, including steroids. The produce the steroid sex hormones and enriched with
Smooth ER
Are large sacs made of membrane that bub off from the ER or Golgi apparatus. Certain freshwater protists have contractile vacuoles that pump out excess water that flows into the cell.
Vacuole
Two Organelles that act as cellular power stations
chloroplasts and Mitochondria
