Science 7-Chapter 17

Cells, Life Processes, Organelles, and "Claim to Fame Scientists"

TermDefinition
RRREGENTS Respiration, Reproduction, Regulation, Excretion, Growth, Nutrition, Transport, Secretion.
R- Reproduction The production of offspring- Can be Sexual (2 Parent) or Asexual (1 Parent)
R- Regulation (Response to Stimulus) When an organism reacts (Response) to a change (Stimulus). Coordinates with Nervous and Endocrine systems to regulate changes- We call this Homeostasis.
E- Excretion The removal of waste products produced by cell activities. Ex. sweating, exhaling, urinating.
G- Growth When an organism increases in size or cell growth.
N- Nutrition Taking in materials from its environment for growth and repair.
T- Transport When usable materials are taken into the living thing (Absorbtion) and distributed throughout the living thing (Circulation).
S- Secretion Producing useful fluids (Secretion) for body activities. Ex. saliva, flowers secrete an odor.
... ...
The Cell Theory- What is it? 1. All living things are made of cells 2. The cell is the basic unit of structure and function in living things (performs all 8 life processes). 3. All cells come from other cells (Debatable)
Cells-What are they? Most are microscopic, performs all 8 life processes, different sizes and shapes (plant vs. animal), and have efficient functionality.
Anton van Leeuwenhoek First saw micro-organisms. Called them "Wee beasties."
Robert Hook Looked at cork and saw tiny room like structures that he labelled as cells.
Schleiden (German Botanist) and Schwann (German Zoologist) Together developed the Cell Theory.
... ...
Nucleus Center of the cell - Controls the cell activities.
Nucleolus Center of nucleus - Produces ribosomes.
Nuclear Membrane Surrounds the nucleus - Controls what moves in and out of the nucleus.
Chromosomes Found inside the nucleus - Contains genetic material.
Cell Membrane Surrounds the cell - Controls what moves in and out of the cell.
Cytoplasm Located throughout the cell - A jelly like material that aids in performing the 8 life processes.
Vacuole Scattered throughout the cell - Stores food, water, and waste. Often larger in plant cells.
Endoplasmic Reticulum (ER) Surrounds the nucleus - Transports material in and out of the nucleus.
Ribosomes Located throughout the cell - Involved in the making of proteins inside the cell.
Lysosome Found throughout the cell - Breaks down food, proteins, old cell parts. Rare in plant cells.
Golgi Body Found throughout the cytoplasm - Packages and secretes proteins.
Cell Wall Located on the outside of the plant cells - It supports and protects the cell. Only found in plant cells.
Chloroplast Scattered throughout the plant cells - Aids in trapping sunlight energy to make food (photosynthesis). Found only in plant cells.
Centrioles Found near the nucleus - Functions only during cell reproduction.
Mitochondria Located throughout the cell - Produces energy for the cell. Known as the "Powerhouse of the cell."
... ...
Cell - Simplest The basic unit of life (the building block).
Tissue - Simple A group of cells form a tissue.
Organ - Moderate When groups of tissue form for a specific function.
Organ System - Complex When groups of organs combine to work or function as one unit.
Organism - Most Complex Aka, a multicellular organism - When a group of organ systems function as a single unit.
... ...
A Cell is Like a City Because... ... there are many different functions happening and working together at the same time.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
