spores

• A spore is the reproductive "seed" of fungi and some bacteria which is capable of spreading through various means (wind, water, animals) and when arriving at a suitable host, with optimum conditions, can germinate and/or cause disease in the host.

deciduous

(of plants and shrubs) shedding foliage at theend of the growing season Leaves fall off these types of trees

evergreen

• a plant having foliage that persists and remains green throughout the year

• Leaves do not fall off the tree/ or change color

flowering

blossoming: the time and process of buddingand unfolding of blossoms Plants that have flowers

Non-flowering

• without flower or bloom and not producing seeds

• Plants without flowers in their growth cycle

annual

• Annual plants are by definition plants whose life cycle lasts only one year, from seed to blooms to seed

chlorophyll

• Chlorophyll is a green pigment found in all plants, algae, and cyanobacteria.

• Chlorophyll is the molecule that absorbs sunlight and uses its energy to synthesize carbohydrates from CO2 and water

• Plants use chlorophyll to trap light needed for photosynthesis

photosynthesisthe process a plant uses to combine sunlight, water, and carbon dioxide to produce oxygen and sugar (energy).

nutrient

• any substance that is assimilated (taken in) by an organisms that is needed for the organism to live, grow, breathe, move

oxygen

ReleasedDuringPhotosynthesis

Carbon dioxide

• Carbon dioxide is used by plants during photosynthesis to make sugars

heat

• a form of energy that is transferred by a difference in temperature

• Plants need heat to survive- they can’t get too cold!

light

• Plants need light (Photosynthesis!)

mammals

• Any of various warm-blooded vertebrate animals of the class Mammalia, including humans, characterized by a covering of hair on the skin.

birds

• Any of various warm-blooded, egg-laying, feathered vertebrates of the class Aves, having forelimbs modified to form wings.

reptiles

• any cold-blooded vertebrate of the class Reptilia including tortoises, turtles, snakes, lizards, alligators, crocodiles, and extinct forms

fish

• cold-blooded aquatic vertebrates usually having scales and breathing through gills

amphibians

• cold-blooded vertebrate typically living on land but breeding in water; aquatic larvae undergo metamorphosis into adult form

• frogs, toads, salamanders, newts, and caecilians are some examples

arthropods

• he largest group of animals on Earth. Arthropods are a type of invertebrate. Common examples include: spiders, ants, butterflies, crabs and dragonflies.

• Animals that have jointed legs, a body divided into two or more parts, and a skeleton on the outside of its body; all arthropods lack a backbone

Examples of Arthropods

vertebrates

having a backbone or spinal column; "fishes and amphibians and reptiles and birds and mammals are vertebrate animals”

invertebratesAn invertebrate is an animal without a backbone. The group includes 95% of all animal species (due to insects and bugs!)Examples: shellfish, worms, jellyfish, sponges, seastars, corals, insects, spiders, snails and slugs

Plant Characteristics

• They make their own food–Chloroplasts contain chlorophyll–Chlorophyll absorbs energy from the

sun–Plants use the energy to make food -

glucose (sugar)–Process is called Photosynthesis

Chloroplasts:

Plant Characteristics

• Plants Have a Cuticle

What is a Cuticle?

–A waxy layer that coats the surface of stems, leaves, and other plant parts exposed to the air.–Keeps plants from

drying out.

Plant Characteristics

• Plant Cells have Cell Walls

What is a Cell Wall

–a plant cell is surrounded by a rigid cell wall –outside of the

cell membrane–helps support

and protect the plant

Animal Characteristics

1. Multicellular2. Consume Food3. Movement4. Exhibit embryonic development

behaviors

• manner of acting or controlling yourself

migration

• the movement of people/animals from one country or locality to another

environment

• the circumstances, objects, or conditions by which one is surrounded

Natural events

• Natural events occur outside of human control

habitat

• the type of environment in which an organism or group normally lives or occurs;

adaptation

• a change in a plant or animal that makes it better able to live in a particular place or situation
