Unit 1 Science Study Guide Plant and Animal Classification Why is it important for scientists to classify animals and plants? Easier to share information Easier to locate animals or plants Shows the relationship to other living things There are 2 types of plants: Vascular: Examples: Celery, Trees, Bushes, Flowers, Grass Nonvascular Examples: Moss, Liverwort, Algae, Lichen Characteristics of Vascular plants: 1.) Have roots and tubes (vascular system) to carry water and nutrients 2.) Have a support structure to hold them up 3.) Grow tall 4.) Produce, seeds, flowers and fruit Characteristics of Non-Vascular plants: 1.) Do not have true roots or tubes (No vascular system) 2.) Grow in damp places. They soak up water through their leaves. 3.) Grow low to the ground. They have no support to hold them up. Animals are divided into 2 Main groups Vertebrates have: ● ● Vertebrates Invertebrates Backbones Examples of Vertebrates: Invertebrates do not have 1.) Animals 2.) Fish 3.) Amphibians 4.) Bird 5.) Reptiles Backbones Examples of Invertebrates: 1.) Insects 2.) Spiders 3.) Mollusks (Clams, oysters, mussels) 4.) Squid / Octopus 5.) Starfish Many invertebrates live in the ocean Critical Thinking 1.) How would understanding the science of living things be more difficult if they weren’t classified? If living things weren’t classified, it would be hard to share information, hard to locate animals and plants and hard to show the relationship between living things.. 2.) Why are vascular plants generally taller than nonvascular plants? Vascular plants have roots and tubes to bring water and nutrients to the top of the plant. Vascular plants also have stems and trunks to support them and make them strong. Non-vascular plants do not have roots and tubes, and they have no stems or trunks to support them. 3.) Why might a break in the main stem of a plant cause it to die? A break in the main stem of a plant would prevent water and nutrients from traveling to the different parts of the plant through its roots and tubes (vascular system). Without water and food, the plant will die.
