Q

What is diffusion?

A

The movement of molecules from an area of high concentration to low concentration

24
Q

What is osmosis?

A

Movement of a solvent into a solution of higher concentration that equalizes the concentration on both sides

25
Q

Endoplasmes reticulum?

A

Passageways where chemicals are made

26
Q

What are Ribosomes?

A

Builds proteins that build new structures
Repair damage
Direct chemical reactions

27
Q

Lysosomes?

A

Filled with enzymes that break up partially digested food

28
Q

Mitochondria

A

Converts nutrients to energy

29
Q

How does the mitochondria convert nutrients to energy?

A

Glucose and carbon hydrates made by plants during photosynthesis are Brocken down by the process of aerobic cellular respiration
ATP is the energy- carrying molecule

30
Q

Cellular respiration

A

Process of oxidizing food molecules to carbon dioxide and water

31
Q

Chloroplast

A

Responsible for photosynthesis

32
Q

Inputs

A

Sunlight
Water
Carbon dioxide

33
Q

Outputs

A

Oxygen and glucose

34
Q

Nucleus

A

Found in eukaryotic cells

Contains the majority of the cells genetic material

35
Q

Mitosis

A

Simple duplication of a cell and it’s parts
Two identical copies from one original
To grow and repair the body

36
Q

Meiosis

A

Cell division that reduces the number of chromosomes

This process is required to produce egg and sperm cells for sexual reproduction

37
Q

When do cells divide?

A

When the ration between the surface area and it’s volume gets smaller

38
Q

Anther

A

Part of the stamen where pollen is produced and stored

39
Q

Pollen grains

A

Cases that contain male gametes

40
Q

Filament

A

Long in stalk that supports the anther

41
Q

Stigma

A

Sticky surface of the pistil that captures pollen grains

42
Q

Style

A

Long thin stalk that supports the stigma

43
Q

Ovary

A

Swollen base of the pistil that contains female gametes

44
Q

Ovules

A

Female gametes

45
Q

Pollination

A

Pollen grains are produced by anthers. They must land on the stigma of the pistil in order to fertilize the flower so that it can produce seeds

46
Q

Self pollination

A

Occurs when pollen is transferred to the pistil of the same flower

47
Q

Cross pollination

A

Pollen is carried to the pistil of a different flower. Wind, and insects are keys to cross pollination

48
Q

Cellula Respiration

A

Transforms carbohydrates into energy in the mitochondria then a chemical reaction causes the oxygen to release the energy present in the carbon hydrate

49
Q

Inputs of cellular respiration

A

Oxygen and carbohydrates

50
Q

Outputs of cellular respiration

A

Carbon dioxide water and energy

51
Q

Taxonomy

A

The science that classifies all living things according to characteristics they have in common

52
Q

Plants

A

Characterized by the fact that they all make their own food from sunshine water and carbon dioxide by means of chlorophyl they don’t move on their own
Ex: mosses, ferns, conifers and flowering plants

53
Q

Animals

A

Either eat plans for the eat other animals. They can move on their own. This kingdom is divided into vertebrates and invertebrate

54
Q

Fungi

A

They neither make or eat their own food, they absorb it. Almost all of a mushrooms body is underground, Made up of tiny string cells called hyphae. Hyphae grow until they run into something that song is thinks is tasty. It’ll be storms nutrients directly into its own cells
Ex: mushroom

55
Q

Bacteria

A

Bacteria is everywhere but you can’t see them because they’re so small. Bacteria is different because it’s made up of just one cell and there is no nucleus

56
Q

Protist

A

Living things that do not belong in the other categories. Period some capture the food someone get food from sun and some do both

57
Q

Archaebacteria

A

Maany have a strikingly different genetic make up from other living things. It’s able to survive in extreme environments deep-sea trenches and Hot Springs
