Biology quiz 2 review

hi

organization

All living things are made of cells

• Unicellular (bacteria)

• Multicellular (Whale)

Genetic Material

Living things that have genetic material in the form of DNA or RNA

• 50% from mom, 50% from Dad

reproduction

Living things must produce new individuals called offspring.

Growth

Living things grow by

• Growth

• Development

Energy

All living things need a source of energy.

• Use energy to break and build up materials - metabolism

Response

Living things must respond to the environment that they are in.

Regulation

Organisms need to maintain homeostasis - stable internal conditions

Adaptation

Living things change over a long period of time and certain changes (adaptation) help them to survive and reproduce ——> evolution.

What is an example of regulation?

it is really cold outside so your body starts to shiver.

What is the difference between growth and development?

Growth is an increase in size, development is a change in form or function

Why is there a debate between viruses being living (biotic) or nonliving (abiotic)?

Viruses are debated as living or nonliving because they can evolve and have genetic material, but can’t reproduce or make energy on their own.

What characteristics of life does a virus have?

They can reproduce and they respond to their environment 

What characteristics of life does a virus not have?

Organization, Genetic material, Growth, Energy, regulation, Adaptation

What is the primary source of energy in Earth’s ecosystems?

The sun

Why do all living things need energy?

Then we would not be able to do things or work

What is a autotrophs and what are the 2 types?

They make their own food aka producers and the two types are chemoautotrophs - bacteria and photoautotrophs - plants and algae 

What is a heterotroph? and the four types?

They eat the food aka consumers and the four types are carnivores, herbivores, omnivores, and decomposers.

What is photosynthesis, and what is its purpose?

 the process in which organisms use energy from sunlight to make the sugar glucose. And its purpose is to make food (glucose)

What organisms perform photosynthesis?

Autotrophs - plants, algae, and some bacteria

Parts of the chloroplast where photosynthesis takes place?

Thylakoids and stroma

Light dependent reactions..what is it? What does it use? What does it produce?

• It is in the thylakoids

• it uses sunlight and water

• it produces oxygen

Light independent (Calvin cycle) reactions…Where is it? What does it use? What does it produce?

• The stoma

• it uses Carbon dioxide

• it produces glucose and ATP and NADP+
