Topic 1 Living Things in the Biosphere Lesson 4 Plants & Animals

QuestionAnswer
Plants, Animals, Protists and Fungi are all in which Domain? Eukarya
Are plants autotrophs or heterotrophs? autotrophs
Are animals autotrophs or heterotrophs? heterotrophs
Describe movement and plants. they are anchored to the ground, and do not move
Describe movement and animals. they move around to get food
What do plants undergo to obtain food (sugar)? photosynthesis
What is the hint for photosynthesis? COW ------GO
Describe Stoma (Stomata). they are located under the leaves; they allow water, oxygen and carbon dioxide to move
Describe the following plant structure- cell wall. a strong, rigid wall around the cell
Describe the following plant structure- vacuole. the largest structure in a plant cell; holds water, waste and food
Describe the following plant structure- chloroplasts. this is where the food is made
Describe the following plant structure- chlorophyll. a pigment that absorbs sunlight for photosynthesis
Describe the following plant structure- leaf. it is used to capture light energy and gas exchange
Describe the following plant structure- stem. provides support and stores food; connects roots to bring water to the leaves
Describe the following plant structure- root. they absorb water and nutrients; they anchor the plant; they store nutrients
What is vascular tissue? groups of cells that work together to transport water, food and minerals; it strengthens the plant which allows them to grow higher
What is the cuticle? a waxy, waterproof layer that covers leaves and stems
What is the phloem? a type of vascular tissue through which food (sugar) moves
What is the xylem? a type of vascular tissue through which water and minerals move
What are nonvascular plants? they are low growing plants without vascular tissue
Where do nonvascular plants live? they live in wet environments to absorb moisture from their surroundings
Why don't nonvascular plants have "true roots"? their roots are just used to anchor the plants, not for water absorption
How are organisms classified? they are classified according to DNA, body structure and development
How are animals classified? they are classified as either vetebrates or invertebrates
What are vertebrates? animals with a backbone
What are invertebrates? animals without a backbone
Most animals are vertebrates or invertebrates? invertebrates
What are the 6 groups of invertebrates? sponges; cnidarians; worms; mollusks; arthropods; echinoderms
What is an exoskeleton? the support structure of the body is on the outside of the animal
What is an endoskeleton? the support structure of the body is on the inside of the animal
In vertebrates, what is the Phylum Cordata? the nerve cord
What are the 3 structures all vertebrates have in common? the notochord; the nerve cord; the throat pouches
Amphibians and reptiles are ectothermic. What does ectothermic mean? they use their environment to stay warm
Birds and mammals are endotherms. What does this mean? they control their temperature internally
What are the 5 major groups of vertebrates? fish; amphibians; reptiles; birds; mammals
Describe mammals. their body temperature internally regulates; they have hair or fur; they produce milk to feed their young
What are adaptations? characteristics that organisms inherit that help them survive
Name some adaptations for movement, in animals. legs, wings, muscular foot, tube foot, jet propulsions, fins
Name some adaptations for conserving water, in animals. they hold water, they filter water, they get fresh water from food
