Species

Answer 20

A group of similar organisms that can mate with each other and produce offspring that can also mate and reproduce

Question 21

Binomial Nomenclature

Answer 21

A 2 part scientific name that Carlos Linnaeus developed to name organisms - it is made up of the organisms genus and species in that order, italicized, with the genus capitalized (ex. Felis catus)

Question 22

How animals are classified into kingdoms and domains

Answer 22

Cell type, ability to make food, the number of cells they contain

Question 23

Vascular plants

Answer 23

Plants that have true vascular tissue for transporting materials such as water, food using tube-like structures inside the plant. These plants grow tall

Question 24

Non-vascular plants

Answer 24

A low growing plant that lacks true vascular tissue for transporting materials and has NO roots for absorbing water from the ground.

Question 25

Angiosperms

Answer 25

A flowering plants that produces seeds encased within protective fruit

Question 26

Gymnosperms

Answer 26

A seed plant that produces "naked" seed (NOT enclosed by a protective fruit)

Question 27

The four functions of animals

Answer 27

To obtain food and oxygen, to maintain homeostasis, to move in someway, and to reproduce

Question 28

Ectotherm

Answer 28

And animal whose body temperature is determined by the temperature of its environment (cold-blooded)

Question 29

Endotherm

Answer 29

An animal whose body temperature is regulated by the internal heat the animal produces (warm-blooded

Question 30

Vertebrate

Answer 30

An animal with a backbone

Question 31

Invertebrate

Answer 31

An animal without a backbone

Question 32

Exoskeleton

Answer 32

Covering covering or skeleton

Question 33

Endoskeleton

Answer 33

An internal skeleton

Question 34

Virus, how they multiply, it's two basic parts

Answer 34

A virus is a tiny, non-living particle that enters than reproduces inside a living cell. They have a protein coat that protects the inner core of genetic material and cannot reproduce on their own. How they multiply: they enter the host cell and take over it's genetic material, making copies of itself that it sends out to the other cells. The host cell is usually destroyed in this process.

Question 35

Host

Answer 35

An organism that provides a source of energy for viruses and other organisms

Question 36

Parasite

Answer 36

An organism that lives on or in the host and causes it harm

Question 37

Vaccine

Answer 37

A substance introduced in the body to produce chemicals that destroy specific viruses- the vaccines are made of dead or weakened virus- they don't cause harm and they activate the body's defenses

Question 38

Bacteria

Answer 38

A single celled organism that lacks a nucleus; prokaryotes. Prokaryote whose genetic material is not contained in a nucleus. The basic parts are the cell wall,cell membrane, cytoplasm, ribosomes, genetic material, flagellum ( whiplike structure that helps a cell move)

Question 39

Binary fission

Answer 39

A form of asexual reproduction- one cell divides to form two identical cells- cell cycle and mitosis

Question 40

Respiration

Answer 40

The process of breaking down food to release energy.

Question 41

Protist

Answer 41

Eukaryotic organism that cannot be classified as an animal, plant, or fungus. They are all eukaryotes (have their genetic material within a nuclear membrane) and they all live in moist environments

Question 42

Animal like protist

Answer 42

Like animals, animal-like protists are heterotrophs and most can move to get food. They're also called protozoans

Question 43

Pseudopod

Answer 43

It means "false foot" there temporary bulges of the cell formed when cytoplasm travels to one location and the rest of the organism follows - they help the organism move around and when the organism extends two pseudopods it can "capture" food creating a vacuole

Question 44

Cilia

Answer 44

Hair-like projections that beat with a wavelike motion - they help creatures move and also sweep food into the organism

Question 45

Fungus

Answer 45

Fungi are autotrophs can be unicellular or multicellular and use pigments to capture the suns energy

Question 46

Fungus-like protists

Answer 46

Heterotrophs, have cell walls, and use spores to reproduce

Question 47

Spore

Answer 47

A tiny cell, that is able to reproduce in a new organism

Question 48

Diverse

Answer 48

It means "made up of people or things that are different from each other" the word diverse works well describing protist because they are so different. Some are single-celled while others are multi-celled. Some are autotrophs while others are heterotrophs. Some can't move but some can.

Question 49

The two basic parts of a virus

Answer 49

1) the inner core containing genetic material. 2) a protein coat that protects a virus (genetic material contains instructions for making new viruses)

Question 50

The characteristics of surface proteins and what they do

Answer 50

Viruses have unique surface proteins - the shape of the proteins allow them to only attach to certain cells in the host (like keys in locks,viruses only fit certain cells - ex. The cold viruses only affect the nose and throat)

Question 51

Plant-like protists

Answer 51

They commonly called "algae" , plant like protists are autotrophs, can be uni- or multicellular, and use pigments to capture the sun. Pigment - chemicals that produce color
