Science

Question 1

Define photosynthesis and what is needed for photosynthesis To occur

Answer 1

Photosynthesis is the process by which a cell captures energy and uses it to make food. what is needed for photosynthesis is carbon dioxide water and light energy

Question 2

What is stage one of photosynthesis?

Answer 2

Energy is captured in the chloroplasts water in the chloroplast is split into hydrogen and oxygen. Oxygen is a waste product and hydrogen goes onto stage too.

Question 3

Write the formula for photosynthesis

Answer 3

Light energy + carbon dioxide +water= glucose and oxygen

Question 4

What stage two of photosynthesis

Answer 4

The hydrogen carbon dioxide have a chemical reaction and then produce glucose and energy

Question 5

Define cellular respiration

Answer 5

Process by which cells obtain energy from glucose cells break down glucose and other food molecules in the presence of oxygen and then release energy

Question 6

What happens in stages one of cellular respiration

Answer 6

It occurs in the cytoplasm of the cell molecules of glucose are broken down into smaller molecules and oxygen is not needed so it is called a anaerobic process. very little energy is released

Question 7

What happens in stage II of cellular respiration

Answer 7

It happens in the mitochondria look The small molecules are broken down even more and this requires oxygen which is called an aerobic process it produces a lot of energy

Question 8

What are the raw materials of photosynthesis

Answer 8

Light energy carbon dioxide and water

Question 9

Where the raw materials of cellular respiration

Answer 9

Oxygen and glucose

Question 10

What is produced during photosynthesis

Answer 10

Glucose and oxygen

Question 11

What is produced during cellular respiration

Answer 11

Light energy carbon dioxide water

Question 12

Compare photosynthesis and Cellular respiration

Answer 12

It helps keep an equal balance of carbon dioxide and oxygen in nature the products and raw materials are Opposite of both Processes

Question 13

Define fermentation

Answer 13

Is energy releasing process but does not require any oxygen it releases less energy then cellular respiration

Question 14

What are the products of Alcohol fermentation

Answer 14

Oxygen and a small amount of energy

Question 15

What is needed to make alcohol fermentation

Answer 15

Yeast and other one celled organisms

Question 16

What is a autotroph

Answer 16

Anything that makes it’s own food for example a plant

Question 17

What is indigestive heterotrophs

Answer 17

Is where food is taken and digested internally for example a human

Question 18

What is a absorptive heterotrophs

Answer 18

They’ll secrete digestive enzymes to the area that surrounds them and break down And absorb foods for example fungi

Question 19

Autotroph

Answer 19

Producer

Question 20

Ingestive heterotrophs

Answer 20

Consumers

Question 21

Absorptive heterotrophs

Answer 21

Consumers
