Cells of Higher animals and plants that contain a nucleus

What are Eukaryotes?

100
a membrane factory that specializes in the synthesis and transport of the protein and lipid components of most of the cell's organelles. The folded membranes of this structure may be rough or smooth.
What is the Endoplasmic Reticulum?
100
Cells communicate with each other to maintain this stable internal environment.
What is homeostasis?
100
occurs naturally through any semipermeable barrier. Does not require life. Requires no energy by the cell.
What is passive transport?
100
movement of water "down" a concentration gradient - from a region of higher water concentration to a region of lower water concentration.
What is Osmosis?
200
Cell such as bacteria, cyanobacteria, and rickettsiae. These cells contain no organelles, and their nuclear material is not encased by a nuclear membrane.
What are Prokaryotes?
200
A network of membranes located near the nucleus. Many molecules pass through this "refining plant" at some point in their maturation.
What is the Golgi Complex?
200
all the chemical tasks of maintaining essential cellular functions.
What is Cellular metabolism?
200
large molecules are moved into the cell by these mechanisms and requires life, biologic activity, and expends energy by the cell.
What is active transport?
200

A cell placed in a hypertonic environment

What is shrink?

300

Movement, conductivity, metabolic absorption, secretion, excretion, respiration, reproduction, and communication.

What are the eight chief cellular functions?

300
saclike structures that originate from the Golgi complex. They contain more than 40 digestive enzymes and are necessary for normal digestion of cellular nutrients, debris, and potentially harmful substances. Abnormalities of these structures are involved in a number of conditions that involve cellular injury and death.
What are Lysosomes?
300

Energy molecule

What is ATP?

300

The difference between hypotonic and hypertonic is..

What is hypotonic has low solute to water concentration and hypertonic has a high solute to water concentration?

300
a cellular internalizing process where a section of the plasma membrane enfolds substances from outside the cell, forming a vesicle that moves into the inside of the cell.
What is Endocytosis?
400

Viruses are not considered living because...

What is they don't have a metabolism, can't reproduce on their own and don't have a cell membrane.

400
organelles found in large numbers in most cells, responsible for cellular respiration and energy production.
What are Mitochondria?
400

All energy for life originates here...

What is the sun?

400
movement of a solute molecule from an area of greater concentration to lesser concentration.
What is Diffusion?
400

Why is the use of stem cells controversial?

Ethical question of the use of embryos

500

RNA protein complexes that are synthesized in the nucleolus and secreted into the cytoplasm through pores in the nuclear envelope. Their chief function is to provide sites for cellular protein synthesis.

What are ribosomes?

500

The ending letters -ose are usually ____ and -ase is usually an ____

What is a sugar and an enzyme?

500

Photolysis is..

What is the splitting of water?

500
The types of transport that don't use energy are ___, ____, ____ and the type of transport that requires energy are ____, ______, ______/

What is diffusion, osmosis, and facilitated diffusion--what is exocytosis, endocytosis, and active transport
