6th grade SCI

TermDefinition
Tissue any of the distinct types of material of which animals or plants are made, consisting of specialized cells and their products.
Organ a part of an organism that is typically self-contained and has a specific vital function, such as the heart or liver in humans.
Radial Symmetry a body plan where parts are arranged around a central axis, allowing an organism or object to be divided into identical halves by multiple planes passing through the center,
Bilateral symmetry body plan where an organism can be divided by a single plane into roughly identical left and right halves, creating mirror images, like humans, dogs, or butterflies.
Describe an animals body plan An animal body plan is the basic blueprint of its structure, defined by features like symmetry (asymmetrical, radial, or bilateral), germ layers (diploblastic or triploblastic), segmentation, the presence and type of body cavity (coelom), and the arrangem
Describe how the structures of animals are related to their symmetry Bilateral Symmetry: Human (Most complex; characterized by a single plane of symmetry creating mirrored left and right halves). Radial Symmetry: Jellyfish (Standard aquatic example; body parts radiate from a central axis, allowing it to sense the environm
Describe what asymmetrical body type means and give an example of an animal An asymmetrical body type has no consistent pattern, axis, or mirror images. It is primarily found in primitive, Sessile (Stationary) organisms that lack true tissues or organs. Example: Sponge (Porifera).
Describe what radio body symmetry means and give an animal example Radial symmetry is a body plan where parts are arranged Equally Around a Central Axis, much like spokes on a bicycle wheel. This allows the animal to sense and interact with its environment from all directions equally. These animals have a top and bottom
Describe what bilateral body cemetery means and give example of animal. Bilateral symmetry is a body plan where only a Single Plane can divide an animal into two Mirror-Image Halves (left and right). This plan is the most common among animals and is essential for Directed, Streamlined Movement. Example: Humans (Other example

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.
