An organism made up of only one cell

Question 1

What is an organism

Answer 1

An organism is a living system with parts that work together to carry out the processes of life

Question 2

Answer 2

An organism that is made up of two or more

Question 3

What is a vertebrae

Answer 3

An animal with a backbone

Question 4

What is an invertebrate

Answer 4

An animal without a backbone

Question 5

What is fungi

Answer 5

Organisms that usually obtain nutrients from dead or decaying matter and cannot carry out photosynthesis

Question 6

What is a protist

Answer 6

An organism that is neither plant nor animal but shares many of the same characteristics of both

Question 7

What is bacteria

Answer 7

Bacteria is The most basic of all unicellular organism and it lacks a nucleus

Question 8

Give an example of the unicellular organism

Diatom

Question 9

Given example of a multicellular organism

Answer 9

Plants and animals

Question 10

Give an example of a animal with the vertebrate

Answer 10

Moose salmon or Bluejay

Question 11

Given example of a I invertebrate

Answer 11

Spider shrimp or snail

Question 12

Give an example of a fungi

Answer 12

Mushrooms

Question 13

Answer 13

Volvox

Question 14

Give an example of bacteria

Answer 14

Escherichia coli

Question 15

What are the five major groups

Answer 15

Animals, bacteria, plants, protists, and fungi

Question 16

How do you classify living things

Answer 16

when you examine the organisms in each group, you see that they have important characteristics in common. This method of classification allows scientists to better understand the diversity of life on earth for example a dog with reclassified animals because it has a backbone

Question 17

How does Paramecium obtain nutrients

Answer 17

When the oral groove contains cilia that creates a current that draw food into a cavity once the cavity is filled the food is enclosed in vacuole where it is slowly digested as the food vacuole travels through the cellS NUTRIENTS DIFFUSE through the vacuoles membrane into the cytoplasm

Question 18

How does amoeba obtain nutrients

Answer 18

When the amoeba needs nutrients chemicals are released into the vacuole to break down the store food the food particles then able to diffuse into the cytoplasm of the cell

Question 19

How do both Paramecium amoeba exchange gases

Answer 19

In unicellular organisms oxygen diffuses across the cell membrane into the cell, carbon dioxide diffuses out of the cell once the concentration of carbon dioxide is higher inside the cell that it is outside of the cell

Question 20

How do unicellular organisms respond to the environment

Answer 20

Unlike humans five senses on unicellular organisms do not have the ability they must sense their surroundings and other ways some bacteria can detect chemicals such as sugar in their environment and move toward them Photosynthetic protist called Euglena can detect light using special sensors all organisms are able to sense their environment and someway and respond to it

Question 21

What is movement

Answer 21

The change in shape or figure of all or part of an organism a characteristic of living things

Question 22

What is locomotion

Answer 22

Locomotion is the movement that takes an object from one place and its environment to another a characteristic of animals animallike protests and some bacteria but not Plants or fungi

Question 23

What is cellular differentiation

Answer 23

The process by which a cell become specialized to perform a specific function

Question 24

What is the definition of tissue

Answer 24

A group of differentiated cells that work together to perform a specific function

Question 25

Definition of organ

Answer 25

To or more tissues that work together to perform one or more functions

Question 26

Definition of organ system

Answer 26

A group of organs that work together to perform related functions

Question 27

What are the functions and organs in the respiratory system

Answer 27

Functions it exchanges oxygen and carbon dioxide between blood and the external environment for major organs there is Lungs windpipe and blood vessels

Question 28

Major functions and major organs for the nervous system

Answer 28

Four major functions there is to responds changes in the internal and next ternal environment of the body and coordinates the function of all of the organ systems.

For major organs they are brain spinal cord sensory organs brackets eyes ears nose tastebuds bracket

Question 29

How does gas exchange occur and bigger vertebrates

Answer 29

In a bigger vertebrae such as humans Air is inhaled through the mouth and nose and passes into the trachea

Question 30

How do small vertebrae’s exchange gas

Answer 30

Small vertebrates use diffusion to obtain oxygen for example the earthworm uses it’s moist skin to exchange gases with the outside air

Question 31

How does gas exchange occurs in plants

Answer 31

Plants have special tissues containing stomates which they use for gas exchange stomates are microscopic pores that control the movement of gases and water vapor into and out of the plant

Question 32

Give one example of how animals respond to the environment

Answer 32

An example would be a cat may see a saucer of milk information from the cat’s-eye travels along nerve cells to the brain with that brain processes the information it to bring to size it wants the milk the brain sends a signal to the Muscles
the cats limbs and the cat moves the saucer of milk and drinks it

Question 33

What unicellular organisms are helpful to humans

Answer 33

Fungi and bacteria for example are decomposers breakdown dead plant and animals material releasing usable nutrients and carbon dioxide back into the environment some bacteria are able to change nitrogen into the air into a material that acts like a plant fertilizer

Question 34

What unicellular organisms are back to the environment and humans

Answer 34

So microorganisms can cause health problems such as acne strep throat and diarrhea in humans so microorganisms can make people temporally ill or others can cause serious diseases several bacterial diseases have killed millions of people throughout history
