What are most fungi?
Most fungi are multicellular eukaryotes.
How do fungi differ from plants?
Fungi do not undergo photosynthesis, do not have chloroplasts or chlorophyll, and are not autotrophs. They are heterotrophs and get food from dead or decaying organisms.
How do fungi reproduce?
Fungi reproduce by spores, not seeds.
What are examples of “good” fungi?
Mushrooms, yeast, bleu cheese, penicillin.
What are examples of “bad” fungi?
Mold, mildew, athlete’s foot, ringworm.
How do plants obtain energy?
Plants are autotrophs that undergo photosynthesis to make food.
What is chlorophyll?
Chlorophyll is a green pigment in a plant’s chloroplasts that is important for photosynthesis.
What are stomata in plants?
Stomata are tiny openings in a plant’s epidermis that allow gases like carbon dioxide, water vapor, and oxygen to enter and exit.
What are the two main groups of plants?
Simple plants (nonvascular) and complex plants (vascular).
What are simple plants?
Simple plants are nonvascular, small, and lack real roots, stems, and leaves. They reproduce by spores.
What are complex plants?
Complex plants are vascular, have roots, stems, and leaves, and reproduce by seeds.
What are gymnosperms?
Gymnosperms are plants with uncovered seeds, such as coniferous trees.
What are angiosperms?
Angiosperms are plants with covered seeds and produce flowers.
What is the process of germination?
Germination is the process of developing from a seed into a plant.
What is the pistil in a flowering plant?
The pistil is the female reproductive organ that includes the stigma, style, ovary, and ovule.
What is the stamen in a flowering plant?
The stamen is the male reproductive organ that consists of the anther and filament, where pollen is produced.
What is pollination?
Pollination is the transfer of pollen to allow fertilization in plants.
What are vertebrates?
Vertabrates are animals that have a backbone. All belong to the Phylum Chordata.
What are invertebrates?
Invertebrates are animals that do not have a backbone. Examples include sponges, cnidarians, worms, mollusks, arthropods, and echinoderms.
What is unique about fish?
Fish are cold-blooded, lay eggs, must live in water, and can be jawless, bony, or cartilage-based.
What is unique about amphibians?
Amphibians are cold-blooded, lay eggs, and must live near water due to their thin skin. They undergo metamorphosis.
What is unique about reptiles?
Reptiles are cold-blooded, lay eggs, and can live in any environment due to their thick, scaly skin.
What is unique about birds?
Birds are warm-blooded, lay eggs, have feathers, hollow bones, wings, and beaks. Most birds can fly. Class aves.
What is unique about mammals?
Mammals are warm-blooded, have hair or fur, give birth to live young, and nurse their young with milk.
