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
